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

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

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

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

AskedWhat 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.
ReplyThe 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.

AskedWhat 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.
ReplyThe 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.

AskedWhat proportion of planned expenditure on UK Integrated Air and Missile Defence during the current Parliament will be allocated to effectors, as opposed to sensors and command-and-control systems.
ReplyThe 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.

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

AskedWhat progress has been made on developing a policy for the active engagement of unmanned aerial systems.
ReplyThe Ministry of Defence (MOD) works closely with partners across Government on a range of Counter-Uncrewed Aerial Systems (C-UAS) issues. The Home Office is responsible for C-UAS policy and strategy in the Homeland during peacetime. During wartime, C-UAS policy falls under the Integrated Air and Missile Defence (IAMD) framework, which the MOD is responsible for. The process of providing Military Aid to the Civil Authority (MACA) is well established and ensures a robust framework under which Defence capabilities may be used to support Other Government Departments. In terms of legislation, work is underway to develop a suitable legislative framework that will enable Defence personnel to operate authorised equipment to protect critical Defence property and activities from the threat of UAS.

AskedWhether there are any formal agreements in place with allied nations for the provision of ground-based air defence for the UK homeland.
ReplyThe UK is a NATO ally and participant in the NATO Integrated Air Defence System (NATINAMDS) a network of interconnected national and NATO systems comprising sensors, command and control facilities, and weapon systems. This system allows the UK to exchange information with Allied nations on a reciprocal basis, to improve sensor coverage and reaction times across the Alliance. Although there are no formal agreements for the provision of effectors of allied nations to be used to defend the UK homeland. NATO has the ability to position assigned or apportioned ground-based air defence effectors in response to emerging threats.

AskedWhat assessment he has made of the UK’s ability to sustain production of major defence equipment during a high-intensity conflict without reliance on overseas supply chains.
ReplyThe Strategic Defence Review (SDR) set out how we must move to warfighting readiness, that includes increasing industrial production and capacity and adding resilience. We are delivering on the SDR vision and the Defence Investment Strategy (DIS) sets out steps forward in this respect. The UK Ministry of Defence (MOD) is strengthening its supply chains to ensure procurement is more resilient, innovative, and agile. Under the Strategic Defence Review and Defence Industrial Strategy, we are developing a collaborative wargaming capability focused on supply chain resilience. This includes surge capacity planning, investment in UK industrial capability, and circular economy initiatives to secure critical raw materials and enable rapid production scaling during times of conflict.
