Written questions by Akehurst.

What assessment he has made of the equipment that would be required to enable a UK Army division to operate as a war-fighting formation.

The Army has undertaken a broad assessment of the capabilities and enablers required for a UK Strategic Reserve Corps (SRC), inclusive of a division, to operate as a credible war‑fighting formation. This assessment is aligned with Defence planning assumptions and NATO standards and is kept under regular review. The assessment also recognises the importance of the entire system to enable divisional operations at scale and tempo, as well as sufficient stocks of munitions, spares, and fuel. These requirements are considered alongside the need for integration with allies, interoperability, and the ability to operate in contested and degraded environments. For reasons of operational security, the Department does not release detailed assessments of specific stock levels.

What assessment he has made of the adequacy of the level of war stocks held by the British Army to replace damaged or destroyed equipment in a high-intensity conflict.

What assessment his Department has made of the potential impact of cancelling the Ajax programme on planned British Army equipment numbers.

As advised within my Written Ministerial Statement dated 22 January 2026, the future of the Ajax platform is being considered as part of the forthcoming Defence Investment Plan (DIP). The DIP will set out investment priorities across Defence, to ensure we can deliver the capabilities required to meet the threats we face today and in the future.

What assessment he has made of the potential implications for this policies of the absence of a mechanised infantry combat vehicle in British Army equipment plans.

Boxer is set to become the new British Mechanised Infantry Vehicle, an eight-by-eight-wheeled, all-terrain, armoured transport vehicle, designed for rapid deployment, high mobility, and modularity.

What role general-purpose frigates within the Royal Navy will have following the development of the Atlantic Bastion concept.

Within the Atlantic Bastion concept, Royal Navy general‑purpose frigates will continue to play an important role in providing maritime presence, patrol, escort and reassurance tasks, while also acting as flexible platforms able to integrate with uncrewed systems. The exact pace and scale of capability enhancements delivered through Atlantic Bastion will be determined through the Defence Investment Plan. The Secretary of State for Defence and First Sea Lord have engaged with counterparts and senior officials from Canada, Norway, Denmark and the Netherlands on the Atlantic Bastion concept through a range of bilateral and multilateral forums, including NATO Defence Ministerial meetings and North Atlantic-focused working groups. The UK will continue to work closely with these Allies to ensure the North Atlantic remains secure and resilient.

Whether anti-submarine warfare is the primary operational focus of the Royal Navy for the foreseeable future.

Anti-submarine warfare remains a central and enduring operational priority for the Royal Navy due to the need to protect the UK’s Continuous at Sea Deterrent and to counter the growing undersea threat in the North Atlantic through the Atlantic Bastion concept.

What assessment he has made of the potential implications for UK maritime security of the United States Navy placing increased strategic emphasis on the Pacific region.

The Strategic Defence Review 25 clearly sets out how the UK will maintain its Defence and Security, including maritime security. This includes the Defence Secretary’s foreword to the review highlighting investment in the hybrid navy as a priority, and in the context of the changing priorities of the United States.

What steps is his Department is taking to ensure interoperability of Type 26 frigates across UK, Canadian, and Norwegian fleets.

The UK works closely with Canada and Norway to ensure interoperability across frigates based on the Type 26 design through regular engagements covering shipbuilding, training, supply chain management, through life sustainability and aligned standard operating procedures.

What discussions he has had with Canada, Norway, Denmark and the Netherlands on cooperation in the North Atlantic in connection with the Atlantic Bastion concept.

Within the Atlantic Bastion concept, Royal Navy general‑purpose frigates will continue to play an important role in providing maritime presence, patrol, escort and reassurance tasks, while also acting as flexible platforms able to integrate with uncrewed systems. The exact pace and scale of capability enhancements delivered through Atlantic Bastion will be determined through the Defence Investment Plan. The Secretary of State for Defence and First Sea Lord have engaged with counterparts and senior officials from Canada, Norway, Denmark and the Netherlands on the Atlantic Bastion concept through a range of bilateral and multilateral forums, including NATO Defence Ministerial meetings and North Atlantic-focused working groups. The UK will continue to work closely with these Allies to ensure the North Atlantic remains secure and resilient.

How many Type 26 anti-submarine warfare frigates are expected to be available for operations in the North Atlantic in support of the Atlantic Bastion concept.

The Type 26 programme will deliver eight anti-submarine warfare frigates for the Royal Navy, which are designed primarily for operations in the North Atlantic and will form a core component of the Atlantic Bastion concept.

What steps his Department is taking to help ensure future armoured vehicle programmes secure intellectual property rights to avoid sole-source support contracts.

The Ministry of Defence (MOD) has an established Intellectual Property (IP) acquisition policy which applies to all procurement contracts including those for equipment and armoured fighting vehicles. Unless special circumstances apply, the MOD’s policy is to leave the ownership of IP resulting from a contract with the contractor, while securing rights to use IP for internal use by the MOD, its technical advisers when necessary, and for competitive contracting for goods and services (including equipment support) needed by the MOD. This approach enables the MOD to operate, maintain and refresh capabilities without being dependent on others (“freedom of action”); and provides value-for-money. ​

Whether his Department expects to incur any cost of safety trials for Ajax vehicles.

As with procurement of any military equipment, it is normal for the Department to pay for trials required to validate compliance with requirements. This includes safety aspects, which we take extremely seriously for Ajax, as with any other capability.

What is the timetable expected for a full safety report into Ajax family vehicles.

As the hon. Member will be aware, investigations into Ajax remain ongoing, and time must be given to ensure all information and evidence is considered. I will continue to keep the house informed of developments, as I have done since the issue arose n Exercise Titan Storm. I released a written Ministerial Statement in the House on 22 January 2026 in which I provided an update to Parliament on the British Army’s Armoured Cavalry Programme (commonly known as Ajax) and the findings of the Ministerial review which has now concluded. It would not be appropriate to release any further specific details than those contained in my previous statement.

What investigations are underway into the safety case for Ajax and the decision-making process that led to Initial Operating Capability being signed off.

As the hon. Member will be aware, investigations into Ajax remain ongoing, and time must be given to ensure all information and evidence is considered. I will continue to keep the house informed of developments, as I have done since the issue arose n Exercise Titan Storm. I released a written Ministerial Statement in the House on 22 January 2026 in which I provided an update to Parliament on the British Army’s Armoured Cavalry Programme (commonly known as Ajax) and the findings of the Ministerial review which has now concluded. It would not be appropriate to release any further specific details than those contained in my previous statement.

Whether contractual mechanisms exist to recover costs if Ajax is cancelled; and what is the estimated financial exposure to the MoD.

Investigations into Ajax remain ongoing, but the Ajax contract does contain mechanisms to ensure General Dynamics rectify any failure to meet requirements or obligations, as well as provisions for terminating the contract if there is a material breach of their obligations. This would allow the Ministry of Defence (MOD) to recover costs. The value of the Ajax contract is already published. It would undermine the MOD's position by exposing its view on the level of costs it feels would be claimed in the event of a termination event of this nature.

What discussions he has had with industry stakeholders on mitigating the impact of delays to the Defence Investment Plan on investment planning.

The Secretary of State for Defence and other Defence Ministers engage routinely and regularly with a wide range of industry stakeholders through established forums, bilateral meetings, and routine commercial engagement on a broad number of topics.

What estimate he has made of the cost of the announcement that 12 F-35As will be bought, beyond the £1.1 billion already announced, once weapons, simulators, and infrastructure are taken into account.

The whole-life cost estimate of £57 billion includes procurement and sustainment of 138 F-35 aircraft to 2069, including technical infrastructure, weapons integration, and aircraft upgrades. The procurement of 12 F-35A rather than 12 F-35B as part of the next procurement package is expected to deliver a saving of up to 25% in initial procurement costs per aircraft for the taxpayer.

What estimate he has made of the number of F-35As that need to be procured to undertake training for the wider UK F-35 fleet and perform the tactical nuclear delivery mission.

The United Kingdom is purchasing at least 12 F-35A aircraft. The aircraft will allow the UK to participate in NATO's Dual Capable Aircraft (DCA) nuclear mission. The nuclear weapons allocated to the NATO DCA nuclear mission are United States (US) nuclear weapons and the US retains control and custody over them. NATO’s 2022 Strategic Concept states that the strategic nuclear forces of the Alliance, particularly those of the US, are the supreme guarantee of the security of the Alliance. The Government has no plans to expand the UK nuclear deterrent beyond our existing submarine-based system but continues to keep its nuclear posture under constant review in light of the international security environment and the actions of potential adversaries.

Whether spending on UK ground-based air defence and Integrated Air and Missile Defence effectors will be deferred until the 2030s.

The Ministry of Defence is committed to modernising the UK's air and missile defence capabilities, including ground-based systems such as Sky Sabre, to ensure robust national resilience as highlighted in the Strategic Defence Review. UK capabilities provide sovereign nation capability and support interoperability with NATO allies and partners. These capabilities, integrated with NATO Allies defend our homeland and contribute to the strength of the NATO Alliance. The Government has committed £1 billion to Integrated Air and Missile Defence in line with the Strategic Defence Review, ensuring investment is prioritised against evolving threats as part of the future Integrated Force. The allocation of investment and timelines for Integrated Air and Missile Defence spending will be set out in the forthcoming Defence Investment Plan.It would not be appropriate to state stockpile levels of munitions for reasons of national security, but these remain under continuous review to maintain operational readiness.

Whether his Department has reviewed existing command arrangements for ground-based air defence in relation to the protection of critical national infrastructure.

The Ministry of Defence (MOD) continually reviews its operational capabilities, including command arrangements for ground-based air defence, to ensure they remain effective and fit for purpose. The protection of the United Kingdom’s critical national infrastructure is a key priority, and the MOD works closely with other Government Departments and agencies to assess and address potential threats. Any updates or changes to command arrangements are informed by regular assessments, operational requirements, and emerging threats to ensure the safety and security of the nation.
