Oral evidence: Work of the Chief of the Air Staff, HC 1108

Oral evidence, 1 February 2023.

Witnesses

Air Chief Marshal Sir Michael Wigston and Air Marshal Sir Richard Knighton.

Chair

Welcome to this Defence Committee hearing; we will be looking at the UK’s air power. I am delighted to welcome Air Chief Marshal Sir Michael Wigston who is Chief of the Air Staff. With him is Air Marshal Sir Richard Knighton, who is the Deputy Commander for Capability and People. You are very much welcome and we very much appreciate your time. I mentioned in the private session that we may be interrupted at 4 o’clock. We will do our best to get through. Before we go into the details of questions—there is much to cover this afternoon—could you just give us an overview as to the air power capability? So very straightforwardly, how many Typhoons have we got, how many F-35s have we got, and how many are operational right now?

Air Chief Marshal Wigston

Just to clarify, Chair, do you want me to focus just on the combat air force in answering that, or would you prefer that I give a broader answer?

Chair

Just on the fast-jet capability, and then we will move on to the other air support assets in a second.

Air Chief Marshal Wigston

The current fast-jet capability consists of the Typhoon force—it is an established force, but it is still growing as a result of decisions that were made in 2015—and, of course, the Lightning force, which you and Committee members were fortunate to visit up at Marham last week. The Typhoon force currently consists of 137 aircraft in seven squadrons, plus the operational conversion unit, plus the trials unit. That is the backbone of the Royal Air Force’s combat air capability—the UK’s combat air capability. It is a phenomenally effective aircraft. In the context of Ukraine-facing activity and NATO, over the last 12 months we have flown over 500 sorties from the north of Norway all the way down through the Black sea and into the Mediterranean. At the same time, we have continued the missions against violent extremists in Iraq and Syria under Operation Shader, and we have even had the ability to deploy a half squadron across to the other side of the world, to Australia, to exercise with 17 other regional air forces last summer. Currently, we have II Squadron in Nevada on Exercise Red Flag, so we are continuing the high-end training, as well as that phenomenal operational drumbeat. We flew over 21,000 hours last year, which is between 5% to 10% more than we would normally fly in a normal year. What was most significant was that it was an almost 100% increase in operational hours. When I talk about the backbone of the Royal Air Force, it is those seven combat air squadrons on Typhoon. The F-35 force is a force in growth still. We have taken delivery of 30 aircraft. Very sadly, we lost one in 2021, so we are down to 29. We will continue to build the force up to 47 by 2025. Aligned with that, of course, is building the technicians who get these aeroplanes in the air and, of course, the pilots who fly them. That is a complex challenge of training the trainers, who then train the new students. I am pleased to say that, just this week, we are going to graduate another two pilots, so we will be up to 34 trained UK pilots, and another seven will graduate between now and August.

Chair

We will come on to pilots. Can I confirm that you have seven squadrons of Typhoon?

Air Chief Marshal Wigston

Seven frontline squadrons, plus the operational conversion unit, plus the trials unit.

Chair

Okay. If we needed to go to war, we have seven squadrons that are up and running and functional, and then you have an additional F-35 squadron, which we met when we went to Marham, so there are eight squadrons.

Air Chief Marshal Wigston

There are. A second Lightning squadron will stand up this year as well, so we will have two frontline Lightning squadrons. That will take us to nine.

Chair

That will take us to nine. When you were a Tornado pilot in Operation Granby, we had 36 squadrons. You know where I am going with this. The world is getting more dangerous, not less. You really are going to be stretching what you have now with the extra duties that are going to come the RAF’s way unless you are able to upgrade. Would you agree with that?

Air Chief Marshal Wigston

The only bit I wouldn’t agree with is that I flew on Op Granby—I was still in flying training at the time—but I recognise the rest of your statement. It is a bit like comparing the size of the Army with the size of Wellington’s army. A combat aircraft today—something like the F-35—is so unbelievably more capable than the aircraft we were flying even 20 years ago, let alone 30 years ago, and that makes up for the absence of mass. We also have aircraft like the Reaper, soon to be the Protector, which bring lethality to the frontline. Air power brings the lethal into defence. Air power takes the fight to the enemy in Iraq and Syria.

Chair

Those squadrons can only be in one airspace at any one time, so while the Wellington comparison works, it then fails—we are going to need more squadrons, I think. We just flag that up, because we are making as much noise as possible given the refresh of the integrated review. As with the Navy, we will probably come to the realisation that our Air Force is very exquisite but not large enough.

Derek Twigg

Sorry, Chair, your question was twofold—how many have we got, and how many can fly?

Chair

You have this wonderful phrase “force elements at readiness”, which is another way of saying how many work and are available at any one time.

Air Chief Marshal Wigston

I try to avoid using force elements at readiness; I use the metric of squadrons, because I see a squadron as a command-and-control unit that is deployable—

Derek Twigg

On the Typhoon, you said 137 aircraft—how many of those could actually fly out today?

Air Chief Marshal Wigston

For the Typhoon, with aircraft that are being upgraded or going through depth maintenance, the forward area available fleet would be about 100, but I will go away to check that figure, because it varies. We can talk a very good story about improving Typhoon availability as the aircraft has matured in service and we have got to understand it.

Derek Twigg

You are saying that about 37 are not flying, because of issues of maintenance and so forth.

Air Marshal Knighton

Mr Twigg, it might be useful to give a bit of context. The Committee—Mr Jones—has asked this question previously. In a steady state, when we are training pilots and preparing for operations, we go through a cycle with the aircraft which, after a certain number of hours, need to be taken offline to be inspected and maintained. Sometimes, spiral upgrades also need to be undertaken. In an average period, those are the numbers that the Chief of the Air Staff is describing. In extremis—we have seen this before—we can generate some of those aircraft more quickly, but we work on the basis that we have enough pilots and enough aircraft for the seven frontline squadrons, the OCU, and the Test and Evaluation Unit. We always need to continue to maintain those aircraft, so that when we need them, we can bring them back into the frontline.

Derek Twigg

And the F-35s?

Air Chief Marshal Wigston

The working assumption on the F-35 is that around 10% of the fleet at any one time will be in depth maintenance or upgrade, leaving the remainder for day-to-day operations. Given that these are technical beasts, which don’t work 100% of the time, there will be an element of difference between those aircraft that are serviceable and those in the forward fleet. In my reckoning, anything above 80% is a good figure when we are dealing with complex combat aircraft.

Chair

Quickly, for a couple of minutes, let us look at the back-up for that. We visited Birmingham, where the Wedgetail—the E-7—is being made. It is a very impressive aircraft. You spoke of the Wellington comparison, and what makes the F-35 an interesting aircraft is having that mother ship being able to control all those assets with the E-7. That prompts the question: when we are growing the fleet of F-35s, why did you purchase only three E-7s and not five, as you intended originally? Would you like to have more?

Air Chief Marshal Wigston

I will answer that by saying that our original analysis identified that the number to give our political decision makers choice, to bring resilience to the force and to add the value you talk about from this phenomenal platform, which really multiplies the force, was five airframes. The decision of three that we came out of the integrated review with I absolutely stand by, because I recognise that the decisions made were in the context of all the other decisions made across defence. My focus now is absolutely on delivering the three that we have signed up to and getting them into service as quickly as we can, so that they enhance the frontline and contribute to NATO. That analysis stands. At a future date, in a future review, it is something that I hope we would come back to, but my focus now is on delivery.

Chair

I understand that No. 10 takes a huge interest in Defence Committee hearings leading up to the integrated review refresh. This is your opportunity to share what you would like to come out of the upgrade. There is a suspicion that there were an awful lot of cuts in your capabilities in air power, and this was one example—moving from five airframes to three. If you look at the equivalent of E-7 over the water—which is the P-8—you have nine of those, whereas you have only three to work over the land. Last opportunity: would you like to see more of these in the integrated review refresh?

Air Chief Marshal Wigston

The integrated review refresh, as you say, is ongoing at the moment—

Chair

Just say yes.

Air Chief Marshal Wigston

The decisions are for the Secretary of State. What we would recognise as a future fleet and an aspiration for a future fleet is five—

Chair

Ah, okay. We got there—thank you.

Air Chief Marshal Wigston

But we recognise that the focus now has to be on delivering the three, and those decisions can come at a later date.

Chair

We saw the three. They are in the bag; we witnessed those.

Air Chief Marshal Wigston

They are on the way.

Mr Francois

Very quickly—we used to have seven E-3s. If you have three, because of maintenance you will probably have only two available on any given day. If you are really unlucky, you will have only one. It has to be more than three to provide you with resilience. When is the E-7 actually going to achieve initial operational capability, given that the E-3s have gone and, in the event of a hot war, we would lose most of our east coast radar stations to cruise missile strikes within 24 hours? When is the E-7 actually going to be in service?

Air Chief Marshal Wigston

Everything I am told and see from Boeing tells me that we will take delivery of the first aircraft next year.

Mr Francois

With respect, Air Chief Marshal, we were not born yesterday. “Take delivery” does not mean “in service”. Could you answer the question that the Committee asked?

Air Chief Marshal Wigston

Mr Francois, you are absolutely right. I was about to get on to what it then takes to get to an operational capability. Of course, you are not immediately operational, and usually the long pole in that is people; it is technicians, pilots and aircrew. What we are doing at the moment is exactly what we did with Poseidon. We have aircrew currently flying in Australia with the Australian air force, and we have engineers in Australia with the Australian air force, learning how to operate this aircraft so that, as quickly as possible, we can get from taking delivery to being operational. It was a matter of months with Poseidon, and I am confident that we can do the same again. On your question about how many and the relevance of three, three aircraft will enable us to make a very meaningful contribution to the NATO airborne early warning network. In return, we will get support from NATO as well. Everything points to the USAF buying into E-7 as well now. This will be a large global fleet alongside the Australians. As I say, there is an aspiration to grow at a future date, but the focus now is on delivery.

Mr Francois

We are always time-limited in these hearings. I will give you one last chance: give us a date when the E-7 will enter service.

Air Chief Marshal Wigston

We will take delivery of our first E-7 in the middle of next year, in 2024.[1]

Chair

When is that then operational?

Air Chief Marshal Wigston

The operational date—Rich might want to add some more detail on this. Because of the change of the programme from five aircraft to three, we still need to get the business case through the approvals process. Part of that process is when we actually define initial operating capability and set a date. That will happen in the next few months—so the middle of 2023. We have had to renegotiate from five aircraft to three—

Mr Francois

Right, so you cannot give us a date. Can you confirm that we are paying not far short of the same amount for three as we were for five? It is about £1.9 billion for three, and we were going to pay £2 billion and a bit for five, weren’t we? Surely that is a false economy.

Air Chief Marshal Wigston

It is a significant reduction. In addition to reducing the number of airframes, we elected to co-locate the Wedgetail up at Lossiemouth with Poseidon, so you have two common airframes and all the efficiencies that come with that. It was a significant reduction in the costs, and that contributed to the overall balancing of the integrated review in 2021.

Mr Francois

For the record, we have given you four opportunities now to tell us when this critical aircraft comes into service, and you have ducked it four times, so let’s move on.

Air Chief Marshal Wigston

If I may, Mr Francois. I absolutely understand what you are saying there. I have tried to give you an indication as best I could—

Chair

Maybe you can take that away. I do recall receiving a call from the American embassy saying that, if you only buy three, it might not be worth setting up the assembly line in Birmingham to make these things, because it is not in their interest to invest in just three rather than five. You did save money, and you were forced to, because of the limits of the money going into the integrated review. But ultimately, the money that you saved on two was not cost-effective—I think that is the point that Mark has made. We need to make progress. John, do you have a quick point?

John Spellar

The MoD has contingency plans and assessments for almost every eventuality. You must have somewhere within the RAF a contingency assessment of, “If things proceed as anticipated, this will be operational by X.” The MoD always does that.

Chair

We are going to return to this.

John Spellar

I would like to know whether you have a contingency plan or an assessment that says this is probable, likely or a possibility.

Air Chief Marshal Wigston

Mr Spellar, in those circumstances, in extremis, it is a bit like we were talking previously about pulling aircraft out of depth servicing. In extremis, with trained and qualified crew—which I know we have, because they are flying in Australia—and with trained and qualified engineers, we would be able to do it very quickly. But actually, it is far better to do it on a programme basis and get it right.

John Spellar

Right, but what is your contingency plan? What is your rough assessment of when this is likely to be?

Air Chief Marshal Wigston

My broad assessment is that it will be a matter of months after we take delivery of the first aircraft.

Chair

That is operational.

Air Chief Marshal Wigston

It will be less than six months, but it will be a matter of months, not years, from in service to operational.

John Spellar

That’s fine.

Chair

We will come back to this, but we are eating into important time to deal with some of the other substantives. Richard, let’s look at manpower.

Richard Drax

Good afternoon, gentlemen. Pilot training, as I am sure you are aware, has been a problem for many years. The NAO investigated in ’15 and ’19, and both reports identified significant problems in the system. The ’19 report noted that, on average, it took 7.1 years for a fast-jet pilot to be trained, against an MoD target of 3.9 years. We met some of your pilots in Marham—I think one pilot was in his ninth year, if I recall, and another was in his eighth, and they still had not qualified to fly the F-35. It is over three years since the Secretary of State said that fixed flying training should be your No. 1 priority. Do you agree with his recent conclusion that things have in fact gone backwards?

Air Chief Marshal Wigston

Mr Drax, I agree with the Secretary of State when he said that things are not what we would want them to be in flying training. But there have been some misunderstandings and misinformation around what is actually going on at the moment and where the backlog that surfaced last year came from, because the part of flying training, which is the contracted military flying training system—I would describe it as the second phase—is actually delivering. It is taut, but it is delivering. That has had an awful lot of NAO attention over the years, and it has had a lot of criticism, but I would point to that as a part of the overall flying training system, which is now working. The challenge that we have had, which began to surface at the end of 2021 and through 2022, was a combination of a number of external factors. The first was the covid-19 pandemic, where we were fortunate enough to be able to recruit 100 pilots or aircrew who had recently left the Air Force and found that they did not have the jobs that they thought they had. We were able to recruit them back into the service, and about another 100 pilots who would otherwise have left over that period elected to stay. At the same time, we were at pace implementing the decisions made in the integrated review. We were winding down the Hercules force. We were retiring Sentry. We were retiring Sentinel. We retired the BAe 146. We had reduced the size of the Chinook force. We had reduced the size of the Puma force. All those were frontline seats, and all those forces had operational conversion units to train that would normally be training people for those seats. So somebody who had been loaded into flying training off the street some three or four or, in some unfortunate cases, five or six years previously, thinking that they were on target for a Hercules operational conversion unit place, found themselves, by the time they got to it, without the frontline seats or the training place to go to. The third external element was of our own making. We consciously prioritised the frontline of the Typhoon force last year and took resource away from the operational conversion unit for the Typhoon just to make sure that we were absolutely ready for anything that Putin might do in terms of escalation or expansion. That logjam ahead of the frontline is what has conspired to create the backlog that made the headlines last summer and that we are working to fix.

Richard Drax

What have you personally done to fix it?

Air Chief Marshal Wigston

In terms of the military flying training system, as I say, that is in a much, much better place. When I became Chief, there were 150 people waiting for their first flying course, waiting for elementary flying training; today, it is fewer than 10. We still have hundreds of people who are waiting to get through to the frontline and are at various stages in the flying training system. However, we have fixed that element which you would recognise as the military flying training system. As you say, the figures in the past for fast jets have been five years, which includes about three and a half years of actual flying training, but it’s seven years in total to get to the frontline. That is the position historically; today it’s five years, and by this time next year it will be four years. It’s the same for multi-engine; it’s the same for rotary wing.

Richard Drax

But what do you say to these hundreds who are waiting to be trained? Of course, time is money, you want these men and women in the cockpit of whatever they are going to fly, and the longer they wait, the longer they aren’t qualified and the fewer planes and qualified pilots you have in the air.

Air Chief Marshal Wigston

Mr Drax, you are absolutely right. First, I absolutely feel for the position they are in; I have absolute sympathy for the position they are in. They are not doing what they joined the Air Force to do and they would give anything to be on the frontline. But what we are doing with them is that we are making sure that, wherever we can, we are giving them career-enhancing personal development opportunities.

Richard Drax

But does that mean flying?

Air Chief Marshal Wigston

It’s not flying, but I have holding officers working in Ministers’ offices in the MoD and working in the Air Staff in the MoD. We have them supporting ambassadors and attachés—

Richard Drax

But they joined to fly—

Air Chief Marshal Wigston

Absolutely.

Richard Drax

And that’s not what they’re doing. You have hundreds queuing up to do this training. When will these hundreds all be through the system? When will you have a system that actually works?

Air Chief Marshal Wigston

Because of all the things that we have put in place over the last six to—well, over the last year—I have absolute confidence that, in the absence of any other changes to our force structure or external injects, by the middle of next year, by the middle of 2024, the maximum hold that anyone will experience between flying courses is six months. The optimum hold will be about three months, because that then gives us flexibility to bring people forward and flexibility for people to take some leave, recuperate, or do some courses. All the signals are that we will get there, for multi-engine and rotary wing, by the middle of next year. For fast jets, it will happen quicker; it will happen this year. The hold for the Typhoon OCU is already down to about two months. So things have improved markedly from where they were even a year ago.

Richard Drax

Well, there are many more questions to go. Chair, I am going to hand back to you, because I know there is a lot more to get through.

Chair

Thank you very much. Over to John, please.

John Spellar

In terms of being trained, including flying, roughly how many weeks of actual training—not just the four years—do they have to undertake to be qualified to fly a fast jet?

Air Chief Marshal Wigston

Fast jet is 35 months.

John Spellar

When you say 35 months, do you mean that they are training every week during the course of that?

Air Chief Marshal Wigston

Or ground school or simulators. A fortunate fast-jet pilot who does not have any holds will do three MFTS courses—the middle phase of training—and then the OCU. That is the 35.

John Spellar

Okay, so just under three years. How many pilots get through the course in that time?

Air Chief Marshal Wigston

Over the last three years, it has been around 20 a year, but as we continue to grow the Typhoon force, as we grow—

Mr Francois

That’s not true, is it?

Chair

Let him finish the answer, Mark, and then you can come back in.

Air Chief Marshal Wigston

As we grow the Lightning force, that number will have to increase. That is something that we had been working hard to put in place at Valley to increase the capacity there—stand fast, the recent developments with the Hawk engine.

John Spellar

So that is 20 pilots a year who may go through the three years. How many pilots are in the whole cohort?

Air Chief Marshal Wigston

We have been training about 100 a year for the last few years.

John Spellar

So 80 out of the 100 a year are not going through at that pace.

Air Chief Marshal Wigston

No, no. They go through to rotary wing or multi-engine.

John Spellar

Okay, so clearly there are a number of bottlenecks in the system, or there have been. You say that you are eroding them away. Who is directly in charge of this? It has been an ongoing saga for a very long time and a concern to Committees for a very long time. Who is operationally dealing with this on a day-to-day basis to actually drive this process of improvement through?

Air Chief Marshal Wigston

Mr Spellar, that was something that I recognised when I became Chief. It is one of the driving factors when I made changes in the headquarters. I moved 22 Group, which is our training group, underneath deputy commander operations. One three star, who is Rich’s counterpart, is responsible for all our frontline force generation and operational flying, but is also responsible for the entirety of the pilot training pipeline and the aircrew training pipeline. That is something that I put in place, recognising exactly what you identify. In the space of my career, I can identify at least three—probably four—cycles where the flying training system has got out of balance, but it is a complex system that is prone to external shocks that reverberate through the system and have the kind of impact that we identified last year.

John Spellar

Shocks happen; it is how quickly you react to them. By the way, do we have a comparator from other, comparable air forces for how long they take to train fast-jet pilots?

Air Chief Marshal Wigston

Yes, we do. We take leading practice from them as much as they take leading practice from us. One of the key debates at the moment is the balance between synthetic flying and live flying, and I would offer that we are at the front of the pack in that regard, in terms of how much we are embracing the opportunities in synthetic training.

John Spellar

The others might not agree with us.

Air Chief Marshal Wigston

Actually, I think that as the technology of the simulators and augmented reality in the actual cockpit is becoming better and better, we are seeing increasing levels of synthetic training before people live fly. For our Lightning pilots—there are no two-seat Lightnings—their first flight in a Lightning is on their own, but they get up to that standard by flying in the simulator.

Mrs Lewell-Buck

Good afternoon again. The defence operational capability audit was ordered in August last year. As a Committee, we asked for an update in October, and we still have not received any feedback, but we have been led to believe that it has concluded. Has it concluded?

Air Marshal Knighton

The report was concluded, and it went to the Defence Secretary. We have not had a response back from the Minister, but it set out the conclusions that the Chief of the Air Staff set out, in terms of the causes and the actions that we are taking being exactly what the DOC audit identified. We were already, and are, acting on the recommendations that were made by the DOC audit that has gone to the Defence Secretary.

Mrs Lewell-Buck

Is there anything in those recommendations that could not have been reached back in 2019, three years ago?

Air Marshal Knighton

As the Chief of the Air Staff set out, in 2019, the focus and the problem was principally around the contracted-out part of the military flying training system, which as a consequence of the changes in airframe type over those previous few years had led to the number of pilots holding before they started growing to an unacceptable level. As CAS has set out, that has now worked its way through the system. In 2019, it was pre-pandemic and pre-this integrated review, so we did not know that we were going to see a reduction in the number of cockpits, nor did we know that we were going to be able to hold on to—and, in fact, attract back into the service—a whole range of pilots who had left and then wanted to rejoin. All those things contributed to the position in which we found ourselves in the summer, and as CAS pointed out, all those issues are being addressed by a whole range of levers. There is no single solution to the problem, and the DOC audit was a useful way to flush all that out, laying that out and making sure that we left no stone unturned in trying to address these issues, because as the Chief and Mr Drax said, that is not what these young men and women join for.

Mrs Lewell-Buck

Is there any reason why we cannot see that operational capability audit?

Air Marshal Knighton

It is secret. It is classified, so you would have to—

Mrs Lewell-Buck

Bearing in mind that you went through some of the recommendations there, what is it that we are not being told, then? I suppose that is what we would want to know.

Air Marshal Knighton

On the basis that it is secret, if I were to tell you what you are not being told, that would tell you what is in there. It was classified, as DOC audits are—DOC audit stands for defence operational capability audit; that is why is it classified—but in terms of the findings, as the Chief and I have set out, they are the principal findings and the steps that we are taking. But it would be a matter for Ministers as to what they would be prepared to redact and share with the Committee.

Air Chief Marshal Wigston

Can I go back to Mr Spellar’s question? One of the things that I am optimistic about, in terms of looking at the future, is the potential to bring technology in to help us model how resilient we are, and how we are able to withstand the sorts of shocks that we have spoken about and which have impacted on us in the past 18 months. It is something that Rich is leading on.

Air Marshal Knighton

There are around 2,000 pilots in our system, in the frontline and going through the training system, and there are multiple factors. There are different course lengths, there are different problems that might occur—weather, a whole range of factors. It is quite a difficult system to really understand and visualise, so although there is a model for the contracted-out element of the military flying training system, we did not have a sort of digital twin of the overall system for our pilot cohort. That is what we are putting into place, taking the models we already have and enabling us to answer the question, so that when we come to the next integrated review, if there is a big increase in the pilot requirement or a reduction in the pilot requirement, we can explain to Ministers and decision makers what that impact would be. That digital twin—it is a slightly grand term—will provide us with a much better tool to understand and model different outcomes and the impact of different decisions.

Chair

Thank you for that.

Mr Francois

Air Chief Marshal, I am sure you would agree—I will just check—that it is your duty to give as candid and accurate responses to this Committee as you can, right?

Air Chief Marshal Wigston

Yes, Mr Francois.

Mr Francois

You told the Committee a few minutes ago, when we were asking about MFTS, that in the last three years about 20 fast-jet pilots have graduated from the programme. Did we hear you right?

Air Chief Marshal Wigston

It is around 20, yes. That is right.

Mr Francois

Okay, because I tabled a question on this exact subject on 26 January: “To ask the Secretary of State for Defence, how many RAF fast-jet pilots have successfully graduated from the MFTS programme in each of the last five years.” In 2021-22, there were 10. That is an official answer from the Department, which is half of what you told the Committee it was. How do you explain that discrepancy?

Air Chief Marshal Wigston

Because of the pandemic and lockdown, courses were delayed and slipped into subsequent years.

Mr Francois

Hang on, you told us a few minutes ago that in the last three years there were 20. I have a PQ here that says you weren’t quite right. I think it is important to be accurate.

Air Chief Marshal Wigston

Mr Francois, I completely accept that. As you say, in-year, the accurate number, because I think your answer is rounded for statistical reasons—

Mr Francois

So it could have been less than 10.

Air Chief Marshal Wigston

It was 12, but some of the other years were slightly above 20. But the throughput in a normal, non-covid year has been around 20.

Mr Francois

I am not going to play semantic games with you, sir. Everyone can see what is happening. You told us that in the last three years it was 20; you have now admitted it was 12 in one of them. Let’s not get bogged down in it—we have made the point. When we went to Marham, we spoke to some F-35 pilots and asked them, “What is the ground truth about how long it really takes?” Before I tell you what they said, how long is it taking now to train a fast-jet pilot, from when they join the service to when they actually get in the cockpit of an F-35?

Air Chief Marshal Wigston

For somebody starting at the end of last year, it was five years. For somebody starting at the end of 2021, it was seven years.

Mr Francois

Right, well, we asked these two chaps, “How long does it take?” The answer we were given was, “If you have average luck, it is seven years.” These two had not been flying the F-35 for that long, I don’t think, and other Members were there. We were told, "If you are lucky”—that was the word used—“it is six,” and the guy who said that was at six years. He said, “My friend here was unlucky, and it was 10.” These are real pilots. There is an old infantry saying that time spent in reconnaissance is rarely wasted. Why is it taking all these years to train someone to fly a fast jet?

Air Chief Marshal Wigston

I absolutely recognise that there are people out there—because I am talking average figures, and those young pilots you were speaking to were from the generation that came through from 2015 onwards, so they battled their way through all the early introduction problems we had with MFTS, which I have spoken about previously. They have had the worst of all worlds, as they have had the misfortune of coming through that process at that time. But the average—

Mr Francois

So you think it is getting better?

Air Chief Marshal Wigston

There is absolutely no doubt it is getting better, Mr Francois.

Mr Francois

Absolutely no doubt.

Air Chief Marshal Wigston

By the end of this year, for fast-jet pilots starting—

Mr Francois

There is someone who disagrees with you. His name is Ben Wallace. In his introductory session with the Committee in October 2019, the Defence Secretary said he had told the Chief of the Air Staff that fixing MFTS should be his No. 1 priority. He gave each of the three service chiefs one overriding priority, and that was yours. In the evidence to the Committee in November 2022, he said, “we have gone effectively backwards from when I gave my instruction to the Chief of the Air Staff… I do not think that is acceptable.” You cannot both be right. Who is right? Is it you, and the Secretary of State is wrong, or is he right and you are wrong?

Air Chief Marshal Wigston

Mr Francois, I completely agree with the Secretary of State that we are not where we would want to be with this, but I can say, as I have assured him after he gave me the task of fixing MFTS—the contracted part of flying training—that that has been fixed.

Mr Francois

With respect, that is not what he told us three months ago. He told us precisely the opposite; he said it is going backwards.

Air Chief Marshal Wigston

What I believe the Secretary of State was referring to was the number of people in hold. The overall number of people has gone up. However, the key factor is not the number of people in hold, but the length of time that they are in hold.

Mr Francois

Air Chief Marshal, MFTS is a broken contract. Everyone knows it. Everyone in the RAF knows it; everyone in industry knows it. This Committee knows it. It is broken. It doesn’t work properly.

Air Chief Marshal Wigston

Mr Francois, I do apologise for interrupting your flow there. It is delivering for us now. We have actually had to ask them to cut back on capacity because of the logjam ahead of the operational conversion units—standfast one element, which is the engine problem we have with the Hawk at the moment. I assure you, Mr Francois, that on the MFTS contract, which the Secretary of State did give to me as my No. 1 task in 2019, we have fixed it and it is delivering.

Mr Francois

We have already caught you out on the numbers. In common patois, as one man down the pub might say to another, he gave you one job and you have failed to do it, haven’t you?

Air Chief Marshal Wigston

The job was fixing MFTS, and, as I said, I am confident that MFTS was fixed. In terms of aircrew training, we have explained the external shocks that have shaken through the system and caused the backlog ahead of the OCU. Mr Francois, the frontline for the last couple of years has been full. Today, it is 94% full. I am one of the few chiefs in recent history who has been able to say that I have a full frontline of pilots. That does not speak to a broken flying training system.

Mr Francois

With the F-35, you have almost exactly as many Brit pilots as you have planes. That is something that came out of Marham.

Air Chief Marshal Wigston

But I have only one frontline squadron. As I say, we are 94% full. When you look at what we have achieved operationally over the last two years, there has been no operational impact. The flying training log jam was caused by covid and us gaining 200 pilots.

Mr Francois

It was caused by a broken contract that has not been managed properly. I will say one last thing and then we will move on. The Battle of Britain was a long while ago. None the less, the point was that we never ran out of planes, but we nearly ran out of pilots. You would think we would have learned that lesson. You have very little in terms of reserves. You can just about match pilots to planes, but if we have to go to war, you have very little left in the locker, and everybody knows it.

Mr Jones

We have spoken about the people we met who have been waiting seven or eight years. I understand your explanation for why that is, but what are you doing to keep them motivated? To be honest, it is a big problem to keep getting pushed back through no fault of your own. Have you had any leakage in terms of people saying it is not worth it?

Air Chief Marshal Wigston

Again, it speaks to the quality, talent and aspiration of these people that, given there have been hundreds in the backlog in the holding system over the last seven years, our recent records show that only two have voluntarily withdrawn because they had run out of patience. The vast majority stick with it and get to the frontline. We have been here before. We were here in the ’90s after Options for Change when we massively reduced the frontline.

Mr Jones

What are you doing, then, to keep them motivated?

Air Chief Marshal Wigston

We have a specific career management desk officer dedicated to the holding officers, and wherever we can, we put them in career-enhancing appointments. I recognise and appreciate their frustration that they are not flying, which is what they joined the Air Force to do, but they are getting experience that will be invaluable to them later in their careers—whether that is working in a Minister’s office, in an embassy or on an operational squadron. Some of our aircrew waiting to go on to the Protector are working as extra crew in the back of a Poseidon. They are learning the skills that they will be applying as Protector operators while flying as supernumerary crew in a Poseidon. I don’t underestimate the challenges in these people getting to the frontline later than we would wish, but the Royal Air Force understands that we have to treat them carefully and that they will still have career aspirations and want to rise through the ranks, and we have to give them those opportunities. As the history of the ’90s and the backlog at the turn of the century shows, people still come through and rise through, even if they have the misfortune of starting their careers in a flying training backlog.

Chair

Just a quick time out while we do some voting procedure—apologies. I have just been in touch with my pairing Whip. The number of Members from the Government and the Opposition is equal in this room. My pairing Whip has said that we can stay and miss the votes if we all promise to stay in the room. As we continue, can the Labour Members confirm that? For the Conservatives, Stuart Anderson has confirmed that. Sorry about that technicality, but it means we can continue uninterrupted. If there is a problem with that arrangement, then we all have to go, so hopefully there will be unity in the Committee.

Robert Courts

Do we need to confirm that, Chairman?

Chair

It is confirmed from our side, but we need confirmation from Labour Members. I will make sure Stuart speaks to the Labour pairing Whip. Let’s move on and turn to the flying training programme itself. Let’s imagine I am fresh out of university or a member of the public, and I want to join the RAF. I go to Cranwell to begin with, which is the first stage where people learn about what the RAF is about. Then I go into phase 1. Is it correct to say that that would be with a frontline squadron somewhere?

Air Marshal Knighton

Elementary flying training, of which that is part.

Air Chief Marshal Wigston

Again, that is at Cranwell.

Chair

Okay. That continues at Cranwell. What aircraft would elementary flying be in?

Air Chief Marshal Wigston

That is in the Prefect.

Chair

Okay. If I pass that, I will then be graded and it is worked out whether I will be multi-engine, helicopter or a jet fighter. Is that correct?

Air Chief Marshal Wigston

Yes.

Chair

I’m looking at the fast-jet component. Would I be flying a Texan?

Air Chief Marshal Wigston

Yes.

Chair

And if I pass that, I then move on to the Hawk.

Air Chief Marshal Wigston

Yes.

Chair

Right. And if I pass that, I can then move on to a simulator of a F-35, not the real thing, and then if I pass that, I can fly operationally in a F-35. Is that it? Is that a fast and furious career in the RAF?

Air Chief Marshal Wigston

For the fast-jet stream, that is right.

Chair

Then home for tea and medals.

Air Marshal Knighton

It is worth reiterating that we forecast that by the end of this year or the beginning of next year the period that that would take, excluding the time at Cranwell, which is about six months, would be just above four years.

Chair

The whole process? Okay. I don’t want to reopen the last discussion we had, but it took one of the pilots we met 10 years to become operational—not 3.9 years, but 10 years.

Air Chief Marshal Wigston

It is to his enormous credit, and that of all his colleagues, that they stuck with it. I have the utmost admiration for them for that.

Chair

I am just getting into the meat of it, but Kevan has caught my attention.

Mr Jones

If we are talking about fast-jet training, one thing that came out when we went to Marham is about women. We asked how many women there were for F-35s. I think we were first told that no one had qualified yet or gone through the process, but it didn’t actually come down to that, because that is not the reason, is it? It is to do with the weight of the helmet.

Air Chief Marshal Wigston

It is the former, actually. To use the language of the Chief of the Defence Staff, it is the “woeful” gender diversity that we have managed to achieve, particularly in aircrew and fast-jet aircrew.

Chair

We are going to come on to that particular subject a bit later. There was an issue to do with the helmet that we flagged up: there needs to be a second, lighter helmet for females to use.

Air Chief Marshal Wigston

I am aware of this issue. With the lighter helmet, which would allow lighter aircrew—not just women—to fly the F-35, we would have challenges clearing it in safety terms, because it does not give the pilot the protection that the other helmet has now. On a case-by-case basis, if a woman or a light person came through the flying training system and there was an operational benefit for them to be flying Lightning, we could make the risk case for flying with a different helmet. But as it stands at the moment, there are sufficient safety grounds for us to say, “That’s the minimum weight limit for Lightning. Whether you are a man or a woman, that is what applies.” Frankly, I would dearly love to be in that position, because we have a far more fundamental problem, which is the lack of women coming through flying training.

Chair

Can we come back to this? I want to focus on the Hawk.

Mr Jones

But can I just say that the problem there is that you are reducing your pool straightaway? If women are lighter—they generally are—they are never going to be able to fly F-35s, so you either stop them flying or ask them to put some weight on.

Air Chief Marshal Wigston

If we were in the fortunate position where I had a woman who was in a position to be flying F-35s, we would absolutely do a bespoke risk-case analysis for that person flying with a different helmet.

Mr Jones

Yes, but they’re not going to get that far, are they? They are going to be weeded out earlier on.

Air Chief Marshal Wigston

They can fly the Hawk. The choice of whether they go to Lightning or Typhoon—

Mr Jones

Come on, let’s be honest. You know what is going to happen. If a woman is a certain weight and she passes all the other sections of it and gets to the point where she could go down the F-35 route, are you going to tell me that they are going to say, “We are going to make a special case for this one”? They’re not.

Air Chief Marshal Wigston

If that person’s aptitude test and the skills they demonstrate, which are different, going through Valley—there is a different skillset to go to Typhoon, compared with Lightning—strongly pointed towards F-35 Lightning, as I say, we would look at the option of using a less safe helmet. That is what we would be saying.

Chair

I want to move on. Just to conclude Kevan’s point, we were told that the weight limit was 5 stone 8 lb. There is an American helmet designed for females, which is lighter, but they cost a quarter of a million pounds each, and we haven’t purchased any. I think there are some health and safety regulations, or UK regs, that prohibit us from doing that. Maybe you can take that away. If you solve that particular issue, we wouldn’t be debating whether a female is over or under 5 stone 8; the determining factor would be whether they can fly the F-35.

Air Chief Marshal Wigston

Mr Chair, I can assure you that no woman has been turned away from Lightning because of a weight limit.

Chair

I don’t think you have had enough pilots coming through to even test the system yet. That is why no woman has come through. We can come back to this, but I am trying to focus on the Hawk, which is part of the mechanism of getting males and females up into the sky, but at the moment it is grounded. Can you confirm that? What has happened with the Hawk?

Air Chief Marshal Wigston

We returned to flying yesterday after a pause to investigate another engine failure at the beginning of the week before last.

Chair

Go round the world and the Hawk has been like the Land Rover: you find it everywhere. It is one of those ubiquitous bits of kit that everybody has enjoyed. Unfortunately, for some reason, it is no longer seen as the great trainer that everybody wants to use. In your own words, what do you think happened? Why did we go from being the world’s leader in training aircraft, which everybody used for understanding how to fly fast jets, to being no longer able to export any? What happened?

Air Chief Marshal Wigston

We are still exporting it, although the production is probably coming to an end—

Chair

That suggests that the exports are not going particularly well.

Air Chief Marshal Wigston

But that is because it is an airframe that was originally designed in the ’70s using 1970s manufacturing techniques. The modern digital design, the materials, the modern manufacture—that is not the Hawk. The latest generation of training aircraft come off the line faster, with more modern technology, and so are more attractive to prospective buyers. I think this is more an issue for BAE Systems than us. We were the first people to buy the Hawk T2—the new generation Hawk, as was—and we will be using it in our flying training system into the 2030s.

Chair

You fly the Hawk, but what is going to happen when these Hawks run out? You are going to need a new trainer aircraft, are you not?

Air Chief Marshal Wigston

Possibly, but we will do some analysis of that, because it may be that a turbo-prop aircraft can fulfil the role, or that synthetics will have reached such a level of development over the next 10 years that we will be able to do that element of training in a synthetic environment. So there are lots of—

Chair

In English, that means that instead of them going up and feeling all the vibrations and all the noise of a jet aircraft, you are going to put them in a simulator. After they have been in a turbo-prop, they are going to do that, and then they are going to straight into an F-35.

Air Chief Marshal Wigston

There is a turbo-prop that is flying around the world today that is capable of minus 4 G to plus 8 G. It absolutely replicates a modern combat aircraft. That is the PC-21. The point is that we will be flying the Hawk T2 until the middle of the next decade, at least, and we have time to look at the options over that period. There is analysis to be done, but certainly no decisions or directions of travel have been identified yet.

Chair

Okay. I’m sorry, but I think this is another one of those little roads that leads to finances. You are making an impassioned case as to why we are now going down the road of training our Air Force pilots using ever more of the simulator, but I think that if you had the money, you would not be pushing people into that space: you would be using a trainer. You would be getting them out into the skies doing the real thing. I cannot help thinking that it is the money that has caused this. We are the only NATO country to do this. That is what raises my suspicions.

Air Chief Marshal Wigston

Chair, you are absolutely right about the physical conditioning. There is an element of live flying that will always be necessary so that the body can experience those unique stresses. However, modern technology, in the simulator environment, thanks in part to the computer-gaming industry and all of the developments and networking available, means that a large part of the training is of better value in a synthetic environment. You can do repetitions. You can put the aircraft in a position that you wouldn’t want to in a live environment. You can give the student all sorts of stresses that you wouldn’t be able to replicate. We get better training in a synthetic environment with our operational squadrons now that they are networked. As I said, there is still analysis to be done, but we are on the threshold of a sort of paradigm shift in how we train our aircrew.

Chair

It is not the same; I appreciate that. I declare my interest as a private pilot, but I can assure you that doing things in a simulator, where you just press reset—“Game over; try again”—you cannot do that in real life. There is a sense of nervousness and a sense of pressure on you, in the real McCoy, that you do not get in a simulator.

Air Chief Marshal Wigston

I completely agree. There is absolutely a minimum level of live flying that will always be a part of this.

Chair

Okay. We’ve made the point. Kevan, over to you.

Mr Jones

In terms of reviewing the contract, why did you employ external consultants?

Air Marshal Knighton

I think you are referring, Mr Jones, to the work with BCG, which was around helping us to build that digital twin and model. There was some expert advice, but actually, fundamentally, what we got from that was a tool that we own that allows us to build that model of our flying training system. In fact, it will actually give us the opportunity to expand that into the modelling other elements of our workforce, so I am already expanding that into modelling the workforce associated with our groundcrew and our engineers. So we got a product at the end of it: we got all the IP and all the data, and it is ours to adjust.

Mr Jones

So it wasn’t just a general consultancy looking at the entire—

Air Marshal Knighton

Not at all.

Mr Jones

In terms of developing that product, who did they speak to? Were they speaking to the actual trainers themselves?

Air Marshal Knighton

Yes, absolutely. Part of the work was to ensure that we understood all the multiple factors that are associated with the outcome—working directly with people in the flying training system to understand what things affect the outcome, and working with those who own the flying training system, as well as our workforce planners. It was deliberately meant to be a method of building what I would euphemistically describe as a digital twin. It enables us to visualise the impact of decisions and to model different outcomes, depending on what levers we are able to pull. It was not a traditional consultancy contract; it was to deliver an actual software tool that we could use.

Mr Jones

So you now have that software. How is it being used?

Air Marshal Knighton

We hold an aircrew pipeline steering group meeting every couple of months. That model is becoming the definitive picture, and that allows us to feed in any changes to waiting times or the number of places, so that we can model from officer cadets to officer commanding—OC to OC.

Mr Jones

Are these just ballpark numbers or are these individuals who are actually put into this system? How does it work?

Air Marshal Knighton

We don’t put individual names in, but it is about individual places and individual pilots progressing through that system. Clearly, as soon as you simulate a different inject into it, then it becomes a forecast rather than absolutely specific.

Mr Jones

Does the system allow you to say, basically, that we will have visibility of where people are at in the system?

Air Marshal Knighton

Yes.

Mr Jones

That should really get to the point that CAS has just made. If you notice that you are getting bottlenecks, for example, you should be able to either turn the pipe up or change something.

Air Marshal Knighton

That is exactly right.

Mr Jones

It sounds like a very valuable tool, but it gets back to this point about the entire system. You have clearly got visibility now. It’s basically, then, who rattles the table and says, “We need to do X.”

Air Marshal Knighton

If I can bring it to life for you, at the meeting of the aircrew pipeline steering group we had before Christmas, we had a specific look at pilot rotary wing—so, helicopter pilot training. We were trying to identify how big a lever we could pull in terms of increasing the number of pilots going through the Chinook OCU, and what that would do to the waiting times. This tool enables us to understand how much of a difference increasing the number of pilots going through the OCU will have on the pipeline and hold times, and how quickly that will change.

Mr Jones

In terms of visibility, does CAS get, for example, a print-out of where people are, to help to monitor it? It is fine having a committee to do these things, but you really have to have somebody at the end of the decision making who is going to say, “Yeah, that’s interesting, but can you do this?”

Air Chief Marshal Wigston

Some of the numbers that we have used today have been the result of the inputs and outputs from that tool.

Mr Jones

Who takes the decision? Does it arrive on your desk, CAS, so that you can say, “Look, I’m bit concerned about this”?

Air Chief Marshal Wigston

Ultimately, yes; but there are a number of people in the organisation who play a part in making those decisions along the way.

Air Marshal Knighton

Just to be really crystal clear for you, Mr Jones, there were some adjustments in the organisational structure of the Air Force before I started in my job last year, which put all the flying training under the deputy commander in charge of operations. Responsibility for managing that process, end to end, now sits with him—which is what the Chief talked about—so he chairs that meeting. I go with him, because I am responsible for aspects of recruitment and career management. I help him, but he is ultimately responsible, and he has got almost all the levers. The only thing that he might escalate to the executive committee or the Chief is if we need to spend money in a particular place that is beyond his delegation, but it is all focused around that single place now.

Mr Jones

He is the person who CAS goes and kicks if it’s not working.

Air Marshal Knighton

That’s one way of putting it.

Air Chief Marshal Wigston

A good real-world example would have been a year ago, when we made the decision to divert resource away from the Typhoon operational conversion units so that we had everything that we had out the door supporting NATO, facing the Russian invasion of Ukraine. A year ago, it would have been nice to say, “This will be the impact of this. This is what the model is telling us will happen over the next two years because of that, and this is what you might need to do to mitigate.” Today we are still in the foothills, but we have the opportunity to do that with this model in a way that we didn’t a year ago.

Derek Twigg

Before we move on to the other matters, I will just ask one simple, quick question to the Air Chief Marshal, as one of the chiefs. On Monday at Defence questions, the Secretary of State said in response to a question about funding: “I am happy to say that we have hollowed out and underfunded.” Do you agree with that and are you happy with the funding for the Air Force?

Air Chief Marshal Wigston

Mr Twigg, when I look all the way back to 2010 and earlier, and look at some of the decisions that our predecessors were forced to take, I would not disagree. What the Secretary of State was talking about was a long period of shortfall, where because of the nature of the operations we were conducting at the time, there were areas where we were able to take risks. Back in 2010 and in the early part of the last decade, we were not facing a near-peer adversary any time soon—although some members of this Committee were calling that out even then. The spending review settlement—the £24-billion uplift in defence funding—and the decisions made in the integrated review absolutely put us on the right course. When the Secretary of State uses that language, of course I agree. But for me, this is ultimately about accelerating some of those decisions.

Derek Twigg

You agree that you are underfunded and hollowed out?

Air Chief Marshal Wigston

Historically, but with the decisions made in 2015 to grow the Typhoon force by two squadrons and to bring back Poseidon maritime patrol, and in 2021 to set up Space Command and continue to grow the F-35 force beyond 48 aircraft up to 74 and grow the Atlas force with around another six platforms later this decade, that is not hollowing out. That is growth for a future, more uncertain world. The funding that went with that, the funding that continues, and the very welcome integrated review refresh that is ongoing, all heads in the right direction.

Derek Twigg

So you are happy with the funding that you got?

Air Chief Marshal Wigston

If you are asking a service chief whether they have enough—in my case, asking the Chief of the Air Staff if they have enough aeroplanes—

Chair

This is your opportunity to say to the world that the RAF needs more money. Threats are coming over the hill and Russia is returning to type, so the RAF needs more funds.

Air Chief Marshal Wigston

If you are asking the Chief of the Air Staff if he needs more aeroplanes, the answer is yes. But I absolutely recognise the huge investment that went into defence in 2021 as a step up, as well as the continued discussion that is going on as part of the refresh and the decisions that the Secretary of State will make in concert with the rest of Government.

Chair

In seriousness, we have had a couple of decades where things have been hollowed out over time—that is what everybody does agree on.

Air Chief Marshal Wigston

Yes, and that is not to castigate my predecessors. Those were risk decisions made because of the context we were operating in at the time. From an Air Force perspective, we had almost complete air superiority in Iraq and Afghanistan. We did not need to worry about defensive aids or air-to-air missiles, or some of the things we are focusing on now, such as Wedgetail.

Mr Jones

Chair, it is very easy for the Secretary of State, and some others, to try and throw this back to 20 years ago. But it was not the last Labour Government that cut the defence budget by 16% from 2010 onwards.

Chair

I was not trying to apportion blame; I was simply trying to say what the lay of the land is. Before we get into a political argument about whose fault it is, I will absolutely say that it was the Conservatives as well. I think there is a general acceptance that we became more complacent after the fall of Soviet Union and the Berlin wall. We can debate that another time.

Sarah Atherton

Going back to the F-35, it is taking around 12 years for a QFI to qualify, and all but two in 207 Squadron are Navy not RAF—I will leave that one with you. Have you got enough instructors?

Air Chief Marshal Wigston

It is not just a Lightning challenge; across all our frontline forces it is a constant challenge to grow the instructors. You need people with the skills and experience. Whether that is weapons instructors, flying instructors, helicopter instructors, that is the critical cohort across all our forces, and particularly a force like Lightning, which is in growth. I would say the same for Poseidon and for Protector.

Sarah Atherton

Have you got American instructors?

Air Marshal Knighton

On squadron, we have three exchanges—an Australian, a US marine corps and a US air force. We have British pilots in their systems as well. We are not specifically using US air force pilots to instruct per se, but we find these exchanges very valuable, because we pick up insights from pilots who come from other countries. Likewise, our pilots are able to give them interesting insights, and then we bring them back into the force.

Air Chief Marshal Wigston

We have industry partners in the simulator—those of you who visited might have seen them—who are also instructing, which again speaks to the enterprise and the working relationship with industry, not only in delivering serviceable aeroplanes but in contributing to generating the trained aircrew.

Sarah Atherton

How much of a challenge is it when the carrier—singular—goes out and you take instructors from Marham?

Air Chief Marshal Wigston

It is a very good question. This is a critical phase in the growth of the Lightning force. We consciously took a pause in the growth of the force—of the trained pilots and engineers—to make sure that the carrier strike group deployment all the way to Japan in 2021 was a success. We recognised that the price we would pay for that—or one of the things that we would have to accept with that—is that the force growth would level off for that period. Over the past year, however, we have absolutely been able to ramp it up again. This year, two pilots are graduating around about now, and another seven will graduate between now and August. The force is on the way and we will be standing up the second frontline squadron this year.

Chair

On the F-35, we have all seen that tweeted video of the F-35 that tried to take off from the aircraft carrier in November 2021 and didn’t get up to the necessary take-off speed, so the pilot had to eject, landing on the deck, and the F-35 went down to the bottom of the sea—I think it has now been retrieved. Has a report now be completed? What was the cause of the aircraft not being able to get up to take-off speed?

Air Chief Marshal Wigston

The investigation has been completed. It was convened by the Defence Safety Authority. My understanding is that the report is still in the review phase. We can come back to you when a publication date is expected, but as is the way of things these days, it will be published.

Chair

And the lessons learned to ensure that it does not happen again. We would be very grateful for that report, once it has been reviewed.

Air Chief Marshal Wigston

The safety-critical lessons that need to be learned, they are almost immediate. The frontline does not wait for a report to be published. I can absolutely assure the Chair and Committee of that.

Sarah Atherton

Just to interrupt, was it not an intake blank blown down, causing 70% power on the ramp at 30 knots?

Chair

Sounds like you have read the report, Sarah.

Air Chief Marshal Wigston

That is ultimately what caused the accident but, as is often the way of these things, a number of events led up to that actually happening. That is why we have these investigations—so we can learn from them.

Mr Francois

Air Chief Marshal, let us turn from one controversy about training our pilots to another one about training other people’s. Politicians and military leaders alike have criticised the actions of former British Armed Forces pilots who provided training to the Chinese military. What is the ground truth on that? There have been lots of rumours, but what is the truth about the extent of that? Is it one or two people, or many? What is the MoD doing to prevent any further such instances of RAF pilots and others training Chinese pilots?

Air Chief Marshal Wigston

Thank you for the question, Mr Francois, and thank you for this Committee’s continued interest in this issue, because it is really important. As I will say in a second, among the things we will look for is for Parliament to give us some beefed-up tools with which we can deal with people who choose to go and work for a potential adversary air force. It has been going on for many years and it goes back to a period when we took a different approach to China. We took a much more engaging approach: we did training, it was formal, we had state visits, and the Red Arrows went and displayed in China in 2016. So I can understand why those people who went and became contractors, helping in simulators and with flying—training at that stage—would have felt that it was a reasonable thing to do. I am limited in what I can say because of the security nature of this issue, but what became a matter of concern and prompted the Ministry of Defence to publicise it was the fact that we saw a significant ramping up of this activity. It was not just the Air Force; it was across all the Armed Forces—it was not just pilots—

Mr Francois

To be fair, we did say that.

Air Chief Marshal Wigston

Yes, you did. And it was happening internationally too. As I say, I am limited in what I can say but, working with the equivalent organisations in our partner air forces, it has become a concerted effort to call out this behaviour for what it is, because it had gone beyond what I would say was the very benign earlier activity.

Mr Francois

Our understanding—perhaps you could confirm whether this is accurate—is that, at least in essence, we were officially providing RAF pilots who were providing flying training to Chinese pilots under an MoD-sponsored scheme up to about 2016, and that some Chinese nationals were receiving officer training at Cranwell as recently as 2019. Is that broadly correct?

Air Chief Marshal Wigston

I don’t have the figures. There were elements of flying-related training but not flying training—for example, flight safety and supervisory training; the sort of things you would do as a normal part of defence engagement with any nation as a way to build relationships—but, as I say, that was at a different time.

Mr Francois

So when the international climate changed and our relationship with China was no longer golden, if you like, and it became more tense and potentially adversarial, we officially stopped doing it, but some people carried on doing it, knowing that the Government’s policy was to stop doing it. Can you give us any idea of how many individuals we are talking about? Are we talking about one or two, or a dozen, or 50? What is the extent of it?

Air Chief Marshal Wigston

It is around 30.

Mr Francois

Around 30?

Air Chief Marshal Wigston

UK people—that is my understanding. Notwithstanding my caution with figures, Mr Francois; I stand to be corrected on that.

Mr Francois

I think on this occasion we will take around 30.

Air Chief Marshal Wigston

But if I may, that is going back a decade. It was not so much the volume that gave us cause for concern in the past year or so; it was just the scale of the recruiting activity that was going on.

Mr Francois

Is not the Official Secrets Act sufficient in this? Are you saying that new legislation is needed?

Air Chief Marshal Wigston

These people are still subject to the Official Secrets Act and they have been personally reminded of that fact as we have become aware. We will continue to look at all the levers we have available. I am conscious that, with things like the National Security Bill going through Parliament, recognising the provisions within that for sanctions does become an important element of this.

Mr Francois

You say you have reminded them, but there are rumours that some of these people are earning a quarter of a million pounds a year. The Chinese know what they are doing, and these people are very well remunerated. A reminder on a crisp bit of headed paper does not seem to be having the desired effect. The situation with China is tense in the Taiwan strait. Their rhetoric is becoming more and more aggressive, but we are not at war with them. But we were not at war with Germany in 1937 and it would surely have been completely inconceivable for an RAF Fighter Command pilot to have gone and trained someone in the Luftwaffe. If you don’t mind me saying so, what has gone wrong that some pilots feel they can do this—potentially train an adversary to kill their comrades?

Air Chief Marshal Wigston

I cannot speak on this. That is not because of classification, but because I don’t know the actual details of the individual motivations of people. What I have taken heart from is that when it was publicised last autumn, a number of our people came forward to talk about when they had been approached, how the approach was made and who made the approach. There is a level of awareness now that this is an insidious third-party recruiting activity, where you might find yourself working for an organisation that is not all that it seems. We have people coming forward now. The security climate has changed; security awareness is much higher. We will continue to do everything we can to bring these—

Mr Francois

Just quickly, because I think others want to come in, it takes many years to train a fast-jet pilot—let’s say that for the moment. These are highly intelligent people. They are not daft, or you wouldn’t put them in charge of a £100 million aeroplane. They must know full well what they are doing. Years ago, this would just have been inconceivable. What has gone wrong?

Air Chief Marshal Wigston

Mr Francois, I absolutely share your frustration and, to an extent, I share—without putting words in your mouth—your disgust, but I can’t speak for their individual motivations. They are still subject to the Official Secrets Act, and we have reminded them of that.

Mr Francois

Have we attempted to prosecute anybody?

Mr Jones

We can’t.

Chair

Kevan, did you want to come in here?

Mr Jones

Well, I sympathise with you. It is a difficult one, this. I agree with what you are doing in reminding people of their obligations, but once someone has left the armed services, I don’t know how you would construct a law that said you could never actually go on and work somewhere—for life. Let’s be honest, it is not just for pilots; it is for other technologies as well. It is one of those things where there seems to be an easy solution, but I’m not sure there is.

Air Chief Marshal Wigston

We are investigating people leaving and getting non-disclosure agreements, and what legal tools we have to hand. That is why I say the continued interest of this Committee would be really helpful. I would welcome that.

Mr Jones

I just don’t think it is possible. If someone is determined to go and work for someone, how would you restrict them from doing that for life? Let’s take a different example: if someone who has been in the Royal Marines wants to go and work for a middle eastern country and advise them on X, Y and Z, can you stop them? I’m not sure you can. I accept that you can remind them of their obligations, but I don’t think it’s an easy one to solve.

Air Chief Marshal Wigston

That’s the issue.

Air Marshal Knighton

It is very difficult to see a route through to resolving it. The Chief talks about potential support from Parliament because there may be a legislative route, but you are more expert than me on how to write that legislation.

Mr Francois

We’re not going to draft legislation now in this Committee, but could we not at least have a blacklist of countries that you absolutely cannot go and work for?

Mrs Lewell-Buck

But that might change over time—in the future, once you’ve legislated.

Mr Jones

But it might change over time.

Mr Francois

But then you change the list.

John Spellar

I think it would be helpful if you could send to us some of the considerations and legal obstacles that you’ve found, in order that we can then take other advice as to the needs. For example, are they subject to a potential recall to the forces after they have left?

Air Marshal Knighton

Depending on how long it is since they have left, they would be considered part of the strategic reserve, and we could recall them.

John Spellar

Precisely. If you are part of the strategic reserve, surely there are obligations on you. I don’t want to pursue this any longer now, but if you could send us some of the problems and considerations, we could then have further thought on this and take further advice.

Air Marshal Knighton

My understanding is that the defence legal services are thinking through these options, and I am sure they will engage with the Committee.

John Spellar

Some engagement with us would be welcome.

Air Marshal Knighton

That is noted, Mr Spellar.

Chair

Colleagues will correct me, but there is a National Security Bill, I think, making its way through. Maybe your legal teams could look at that to see if you require further powers, and that you bolster those. Clearly, what you have at the moment is not good enough to deter people.

Mr Jones

The Bill’s a shambles as it is; it doesn’t need any more things added to it. [Laughter.]

Chair

On that note—from one controversy to another, please, if we can now address a rather dark chapter for the RAF, which is to do with the formal diversity drive that you went through not too long ago. In summary, this was about a precedence of selection given to ethnic minority and female pilots over better-qualified white pilots, in order to improve the RAF’s diversity profile, even though it could materially affect the RAF’s operational performance. This all began back in November 2020 and ran until March 2021. Group Captain Lizzy Nicholl was then placed in charge of recruitment and selection at that time, and it was she who refused to continue this formal programme. I understand that she determined that about 160 cases of positive discrimination had taken place and she ended up having to resign because she did not wish to go through with this policy. In October 2022, an inquiry was launched—I think it was launched by yourself, Sir—to look into the circumstances that led to the resignation of Group Captain Lizzy Nicholl. Clearly, there has been a lack of integrity at the very top of the RAF. Your own legal team’s advice said it would break the law if you pursued a policy of positive discrimination. So this wasn’t just one individual trying to improve the diversity numbers, but a formal directive from the top, because Group Captain Lizzy Nicholl was ordered by her boss, Air Commodore Jo Lincoln, who is the Director of RAF Workforce Requirements. In turn, she was ordered by her boss, Air Vice-Marshal Maria Byford, who is Chief of Personnel, who I’m guessing was ordered by her boss, the head of the Air Force, which I think is you. My question today is this: did the wrong person resign?

Air Chief Marshal Wigston

Chair, I recognise some of what you say there, but I would like to offer a counterview to some of that. However, I will absolutely start by saying that I very much regret, and I’m very sorry, that the group captain you mentioned felt that she had no alternative but to resign. As I say, I very much regret that she found herself in that position. There is a non-statutory inquiry ongoing into this; we’ve asked for it to be convened and run by the Army. And it hasn’t made its findings to me yet. I look forward to them. I want the Royal Air Force to learn from this, and we will. And it’s my understanding that the Secretary of State has undertaken to share the findings with this Committee as well. However, in terms of what you said, I can absolutely assure this Committee that there was no compromise of entry standards. There was no impact on the standard of recruits from any background. There was no impact on the frontline or on operational effectiveness.

Chair

I hear that, and it is understood. You were taking people who had passed the courses. What you weren’t doing is allowing those who had achieved the best in the class to then go forward. Some of those people, because of their skin colour, were then held back or not allowed to progress, because others who possibly were not as good as their standards were then given preferential treatment. That is against the law.

Air Chief Marshal Wigston

If I may, Mr Chair, I’ll offer a different perspective on that. Certainly, around the matter that caused the group captain to resign, I am absolutely clear that there was no discrimination, because the direction that she challenged was never implemented. But what it did do was that it did prompt us—

Mr Francois

Huh?

Air Chief Marshal Wigston

It was not implemented, so there was no discrimination in the case of that August ’22 matter. But what it did prompt us to do—

Chair

Sorry—there was a time between November 2020 and March 2021 where this was the policy.

Air Chief Marshal Wigston

Chair, I will come to that if I may. It prompted us to look into historical recruiting. We did identify mistakes and we accepted that we had made mistakes, and we accepted it publicly in last September. The mistakes we identified hinged on our categorisation of when recruitment finished and when training started, and so which part of the Equality Act applied. This was the premise that we worked on until the beginning of last year, when it was recognised as being in error. But prior to that—and this is to your point, I think—a limited number of women and ethnic minority candidates who had passed through the recruiting system were allocated to additional slots on basic training. But that process of course loading should have been done under the less permissive parts of the Equality Act, because technically it was still recruiting, even though they had passed all of the recruitment process. In answer to your question, Mr Chair, throughout all of this I have seen nothing to indicate that people were giving directions that they believed to be unlawful. They were working on the assumption that what we were doing was lawful, and it was all done with the best of intent to tackle this intractable challenge. As I say, I am very sorry that the group captain found herself in a position where she felt she had no option but to resign.

Chair

So she resigned because she saw the legal advice that said it was unlawful, but she was encouraged to continue with this. That is why she felt she had no option. We should be conscious in this Committee that this is being investigated. I think it is going to go to court as well—to a tribunal—and therefore we need to be careful as to how far we pursue this. I ask colleagues to have that in mind when they comment on this. The question today, which I will leave hanging, is that, to the extent that there was support for this going up the chain of command, there are questions of integrity that need to be addressed. This is a blot on the RAF copy book.

Air Chief Marshal Wigston

I absolutely recognise the reputational harm that was done, but some of what you said in your opening remarks implied that there were different standards applied and that there was active discrimination against white men. But that was not the case. This was people within the organisation who felt that they were acting within the law, and who understood that they were acting within the law. They were doing it with the best of intentions to tackle this intractable challenge around diversity. As I mentioned earlier, the Air Force has a real challenge—across the Armed Forces we have a challenge—with our levels of diversity.

Chair

This is clearly not the way to solve it.

Mrs Lewell-Buck

Just to clarify for me—I might have missed it—you said it was the direction that she challenged. Where exactly did the direction come from, and what exactly was that direction? Just make it really clear.

Air Chief Marshal Wigston

I am very happy to talk about what we have discovered around the historical mistakes we made, but for the reasons that Mr Chair discussed, I really cannot talk about the specific instance in August last year when the group captain elected to resign. As I say, the findings will be shared with the Committee, and we will be as open as we need to be on this.

Chair

When is that report due? I hear that it is imminent. Is that correct?

Air Marshal Knighton

I commissioned the report back in November. It is worth just describing the process. There is a review of emails and literature and a series of interviews. Those interviews have concluded. Many on the Committee will know better than I that the investigation will then be written up, and then it is shared with those who have been interviewed. They have the opportunity to comment, and then the report is reviewed again by those who author it. We are in that stage at the moment. I speak regularly to the retired major general who is doing that work to get an update. He is understandably reluctant to be definitive about when it will be ready, but you can be assured that he is trying to move it forward as quickly as possible.

Chair

Okay. Sarah has done more on this, to try to expose the challenges of diversity. I would like to give her the floor for a second.

Sarah Atherton

Thanks. You obviously know the difference between positive discrimination and positive action. I personally do not agree with either of them, but I appreciate that there is an investigation under way. I am more concerned about people such as Group Captain Lizzy Nicholl, who tried to raise a concern within our military—in this case, in the RAF. After a long, successful career, she felt that she had to leave. We know that we have a problem with retention. I am more concerned about what the RAF’s whistleblowing process is. What protection are you giving to personnel when they raise legitimate concerns? She believed she was drawing attention to an illegal action. What is your whistleblowing policy? What protection have you got for people who are trying to do the right thing, and is your chain of command learning?

Air Chief Marshal Wigston

Ms Atherton, I absolutely agree. We have been very careful to ensure that this officer had the support that she needed. I spoke to her after she resigned; Richard has spoken to her on more than one occasion. I am really limited in what I can say about that case, for the reasons that the Chair outlined. I can give earlier examples where people have come forward—very junior officers, in one case, from a careers office. They recognised that the direction needed legal advice—this was back in 2020 or 2021—and that person was listened to and was proved right. The legal advice was refined, and the whole organisation benefited, so I have examples where challenge worked and the organisation responded correctly. A direction that could have left the Air Force vulnerable to legal challenge was not implemented, and that was because of a junior officer making a challenge, so there are good things that I can point to on this. On the Chair’s point, I suspect that the inquiry will identify that the sharing of information—the communication both across and up and down the organisation—was not what it should have been. I have been out on the ground apologising for that, to people in recruitment and selection in particular. I make no apologies for setting a challenging, aspirational goal for the Royal Air Force on diversity; I want us to be able to recruit from every corner of British society, and to be successful at it. Those are challenging goals and stretching, aspirational levels of ambition. One mistake that we have identified is this. That aspiration or goal was stretching. It was translated into the strategy, and then into our business plan—the command plan. It then trickled down into individual recruiting officers’ and sergeants’ in-year personal objectives. As it was an unattainable target, it put intolerable stress on them, and that was a failing of the organisation’s; it is a failing when an aspirational goal becomes an individual target.

Mr Francois

To clarify, you have said that this was never implemented, but that is because the group captain resigned rather than implement it. If it had not been for what she did, it would have been implemented, wouldn’t it?

Air Chief Marshal Wigston

Mr Francois, I would really rather not go into the circumstances of that officer’s resignation. The matter that she challenged was never implemented.

Chair

We have to be conscious that we should not do that, though Mark’s point is valid.

Mr Francois

Fair enough. I will leave it there.

Chair

But I would say that if your overall task is to encourage females to join the RAF, which is absolutely commendable, and something this Committee would agree with, and that policy leads to a senior female officer having to resign as a whistleblower, that is clearly not going to help your cause, I am afraid.

Derek Twigg

You keep saying that the policy that she resigned over was never implemented—those were your words—so who took the decision to have that policy that was never implemented?

Air Chief Marshal Wigston

That was direction pertaining to recruitment.

Derek Twigg

No, the question I am asking is: who took the decision on the policy that you said was never implemented?

Air Chief Marshal Wigston

Those will be matters that the ongoing inquiry looks into, and I do not know what its conclusions are.

Derek Twigg

Sorry—you are head of the service, and you do not know who took the decision?

Air Chief Marshal Wigston

There are a number of people involved in setting directions.

Derek Twigg

Did you take the decision?

Air Chief Marshal Wigston

I set the aspirational goal and the level of ambition for the service, and as I have said—

Derek Twigg

But did you take the decision on this particular policy that was not implemented?

Air Chief Marshal Wigston

I set the direction, and I set the aspirational targets for the Royal Air Force to achieve.
