Ajax Programme

Al Carns Excerpts

Wednesday 14th January 2026 Westminster Hall

[The Minister for the Armed Forces (Al Carns)]

It is a pleasure to serve under your chairmanship, Mr Stuart. I am grateful to the hon. and gallant Member for Huntingdon (Ben Obese-Jecty) for securing this debate.

It will not be lost on the audience that I am not the Minister of State for Defence Readiness and Industry, but I am a former Royal Marine with 24 years of service and now also the Minister responsible for the armed forces. I can assure hon. Members of this Government’s commitment to the safety of our service personnel. That is absolutely paramount. It underpins a bond of trust between all MOD activity and the Government, and it is a vital strand of our responsibility to ensure that our service personnel are provided with the correct equipment that is safe, but also reliable and effective.

That is why Ministers were so alarmed by the symptoms reported by 35 soldiers who operated Ajax vehicles during November’s exercise Titan Storm. I can update Members that of those 35 people, nine are now back to normal duties, two were found to be suffering from symptoms unrelated to Ajax and the remaining 24 continue to be monitored by our medical services, primarily for hearing and vibration. We will ensure that they receive all necessary support as they progress. I can also confirm that the Minister for Defence Readiness and Industry, my hon. Friend the Member for Plymouth Sutton and Devonport (Luke Pollard), alongside the Chief of the General Staff, will visit affected units and speak to affected soldiers later this week, having written to them at the end of the year.

Exercise Titan Storm represented the latest chapter in a programme that has been well documented by parliamentary Committees and independent MOD reports. Ajax was approved in 2014 with a date for initial operating capability of 2020. Today, after significant delays, just over 180 vehicles have been delivered. The symptoms reported by some of our soldiers operating Ajax during Exercise Titan Storm have led to four separate, rigorous investigations. The Minister for Defence Readiness and Industry plans to further update the House on this matter next week, so hon. Members will understand that I may leave some of the specific questions—including the 37 from the hon. Member for Huntingdon; on average, one a minute—for that Minister to answer in detail.

Along with the investigations into the vehicles by the Defence Accident Investigation Branch and the Army safety investigation team, which were set out to Parliament by the Minister for Defence Readiness and Industry on 8 December, a ministerial-led review into the implementation of previous recommendations has also been commissioned. It focuses on the basis of written assurances given to Ministers ahead of the announcement of initial operating capability in November. As set out in his written ministerial statement on 18 December, the Minister for Defence Readiness and Industry subsequently also directed a pause on all Ajax trials to allow for an investigation into a second safety incident reported during a trial at Bovington on 12 December.

Each of the 23 affected vehicles have now undergone 45-point inspections, with further instrumental testing, including for noise and vibration, taking place literally as we speak. In that incident, the affected soldier received medical support and did not require hospitalisation. The vehicle involved was not one of the 23 from Exercise Titan Storm; it was a separate vehicle being used to establish a safety baseline for comparison. I can confirm that that soldier has now returned to duty with no issues whatsoever, and that discussions are ongoing between the Minister for Defence Readiness and Industry and officials within the Department on appropriate next steps regarding the potential restart of those trials.

As many of my Welsh colleagues have pointed out, the Ajax vehicles are built in Merthyr Tydfil to support a UK-wide supply chain of more than 230 companies and over 4,100 jobs. Because of the importance of the programme to south Wales, Ministers have been in close contact with the Welsh Government; the Minister for Defence Readiness and Industry met the Welsh Economy Minister, Rebecca Evans on 15 December.

As I mentioned earlier, because previous investigations and adjustments should have fixed the recent challenges to the programme, the Minister for Defence Readiness and Industry has put in place a ministerial-led review that will assess how the Department has implemented the recommendations of previous reviews, and suggest improvements to the process of providing timely and accurate information to Ministers. To ensure the independence and rigour of that process, that review is conducted by experts who are not part of the Ajax programme. Ministers, the Chief of the General Staff and officials are also working closely with General Dynamics to resolve the issues, and will continue to do so. Most recently, at ministerial level, the Minister for Defence Readiness and Industry met senior managers from General Dynamics on 9 December. He plans to meet them again next week, and has future plans that are in train to meet the workforce again.

It is important that each of the investigation teams are given the time and space required to get to the bottom of the recent incidents, and past failures, so that we can take the most appropriate and accountable next steps. I want to be clear that there is no predetermined outcome. Ministers will be led by the facts and all options are absolutely on the table. As the Defence Secretary has said of this programme, we must either back it or indeed scrap it.

[Stuart Anderson]

When or if trials resume, what assurances will we get that no future British troops will be put in harm’s way by testing Ajax?

[Al Carns]

I can assure the hon. Member—and I note his background—that the safety of our armed forces will be the No. 1 priority when we commence those trials. That has to be the baseline common denominator as we move forward. I reiterate that the Defence Secretary said that we must back it or scrap it; the evidence will allow us to make that decision.

I will cover off some of the 37 questions that were asked earlier. When we talk about initial operating capability, there is a slight dichotomy. We mentioned a perceived rush to IOC for Ajax on the one hand; on the other hand, collectively hon. Members are asking why Boxer’s IOC is moving. It cannot be one or t’other. We have got to allow the teams and experts to ensure that IOC is met in the safest possible manner and that any lessons from Ajax are pulled across into the Boxer programme and other big capability programmes, as has been mentioned by some hon. Members, so that we can understand and learn from them.

We are also, in some cases, our own worst enemy—we have had over 1,000 capability requirement changes throughout the programme. As we change the capability, the platform changes, the cost changes and the time-trialling system changes, and we need to reduce that as we move forward with major capabilities. The Minister for Defence Readiness and Industry will update the House in due course, covering things such as capability changes and requirements and how many noise vibration issues there were in Titan Storm, and he will answer the rest of the multitude of very detailed questions that were asked earlier today.

On British military doctrine, it is really important to recognise that Ukraine is changing the whole character of conflict and how we fight. Terms such as armoured recce, ranges of gun systems and the reason why we built the tank in the first place—to carry a gun and to deliver firepower at pace—are changing because of the development of technology. We are wrestling with a whole set of capability changes, which are changing the character of conflict. We must not learn false lessons from Ukraine but pull the most effective ones and draw them into our capability programmes that in some cases were set in place 10 to 15 years ago. It is a very complex system of moving forward, but I can assure Members that we are learning those lessons from Ukraine and trying to incorporate them as best we can into the current programmes. What I would say is that Ajax started in 2014, and we have had 10 years of progress, but also a huge amount of mistakes. Those lessons will be pulled across into Boxer.

My hon. Friend the Member for Merthyr Tydfil and Aberdare (Gerald Jones) outlined the invaluable skills and capability of the staff that have actually created these systems, and some of the capabilities that they have brough to bear are absolutely second to none. The Minister for Defence Readiness and Industry will report next week, and he is more than happy to meet both union and industry visitors in due course.

The hon. Member for Weald of Kent (Katie Lam) highlighted some issues with the direct threat to our armed forces that the capability may present. What I would say is: allow the facts to do the talking, allow the review to come out next week, allow the report to be presented to the House, and then let us work out whether this capability can actually add value, whether it is in the armoured recce space or armoured infantry roles and so on. From my perspective, it is important to allow the facts and the honesty of the review to pull through.

I express my gratitude once again to the hon. and gallant Member for Huntingdon for introducing the debate and to all Members for their continued attention to Ajax programme. I trust that we have collectively been clear about where we stand on this. Multiple investigations are under way. All Ajax activity—training, exercise and trials—has been paused until these investigations are complete. Ministers will receive findings in the coming weeks, and all options remain on the table.

Importantly—it has been mentioned multiple times, and I have been at the bottom of the food chain in the military as well—I thank Alfie and Fill Your Boots; I thank the men and the officers for highlighting these concerns and speaking truth to power; and I thank the armed forces collectively for working collaboratively with us to come to an amenable solution that gives them the capability that they deserve.
