The Ministry of Defence (MOD) does not publish munition stockpile levels, as disclosure of such information could undermine national and operational security. The UK’s weapons stockpile is maintained at levels required by the Armed Forces and is actively reviewed to balance threats, availability, industrial capacity, and technology.

The MOD reviews and updates our munitions plan periodically, ensuring that planning assumptions remain aligned with the evolving threat environment and lessons identified from recent operations. Requirements for Brimstone, Paveway IV, SPEAR 3, Meteor and ASRAAM capabilities will be considered as part of this broader review to ensure UK stockpiles remain sufficient to meet the demands of current and future operations.

The UK’s munition stockpile levels and operational planning assumptions are classified; disclosure of such information could undermine national and operational security. The Ministry of Defence (MOD) works with the Military Commands and industry to regularly review munitions demand, supply resilience and opportunities to increase production capacity. This ensures our munitions planning assumptions remain aligned with the evolving threat environment and lessons identified from recent operations.

As we have set out in the Defence Investment Plan, we are investing in increasing munitions production capacity, including plans for six new energetics and munitions factories and an "always on" production model for some key munitions.

As the hon. Gentleman will understand I am withholding the date that this capability will be available as it would harm the capability, effectiveness, and security of the Armed Forces.

As previously advised within my answer to Question 23368, the Department is reviewing options to ensure future capability remains affordable and aligned with Defence priorities.

The full scope of Capability Uplift Package 1 of the Land Ground Based Air Defence (GBAD) Programme comprises both equipment enhancements to improve current operational capability and assessment work to inform future capability development.

The Government accepted all 62 recommendations of the Strategic Defence Review and is delivering them through the Defence Investment Plan, backed by record investment in Defence.

For Integrated Air and Missile Defence (IAMD), the Defence Investment Plan invests a further £790 million in dedicated homeland IAMD, focused on improving foundational capabilities through enhanced Command and Control and sensing systems, including new radars and control systems.

The Defence Investment Plan also invests in Deep Precision Strike and long-range weapons capabilities across Defence, including Precision Strike Missiles and other long-range strike capabilities, strengthening the Integrated Force's ability to deter and respond to threats. Work continues within the department to mature the IAMD enterprise to prioritise the work and engagement with industry to deliver these fused requirements.

Defence is also improving the sensing capabilities that underpin Integrated Air and Missile Defence through a layered NATO-integrated approach, drawing on ground-based, airborne, maritime and space-based sensors to improve the ability to detect, assess and respond to threats across the Euro-Atlantic

In addition, Defence continues to improve the sensing capabilities that underpin Integrated Air and Missile Defence, working closely with NATO as part of a layered and integrated approach to the defence of the UK and the Euro-Atlantic.

The UK, through the National Armaments Director, routinely works with NATO Allies, and global partner nations to identify opportunities for co-development and procurement seeking efficiency wherever possible.

I refer the hon. Member to the Answer I gave him on 26 May 2026 to Question 2224.

The Ministry of Defence continues to assess options to deliver the required Ground Based Air Defence capability in an affordable manner.

The programme is pursuing a more incremental and adaptable approach, prioritising lower-cost and faster-to-field capabilities, including interceptor uncrewed aircraft systems, jammers, command and control systems and sensors, while continuing to assess options for the progressive introduction of additional layered air defence capabilities as resources permit.

The programme is also seeking to maximise lessons and opportunities arising from operational capability acquisitions and international collaboration.

The UK is stepping up air defence supplies to Ukraine to help protect its civilians, urban centres and critical national infrastructure.

At the latest UDCG on 8 September the UK announced we will contribute a further £100 million towards NATO’s Prioritised Ukraine Requirements List (PURL), which will support the delivery of Patriot missiles and other air defence equipment before the winter.

Prior to this at the previous UDCG meeting on 18 June, the UK announced the delivery of more than 350 air defence missiles and radars. In addition to this, twenty remotely guided counter-drone turrets, acquired from Estonia, have now been delivered, which are designed specifically to defeat Shahed-style attack drones.

In addition, we continue to regularly deliver hundreds of UK produced Lightweight Multi-Role Missile (LMM) air defence missiles to Ukraine.

Previous delays have been overcome through a revised plan of combined USA and UK based testing, with final elements of safe separation trials concluding in the USA in June 2026 and further UK testing being conducted in August 2026. Paveway IV has been operationally available since March 2026. Brimstone 3 trial data is undergoing necessary analysis required prior to issuance of operational clearances.

Protector has been employed on operations since November 25, with Full Motion Video being passed to operational users. Metadata issues are expected to be resolved by the end of Quarter 3 of Financial Year 2026-27 (October to December 2026).

The STRATUS programme review is due to report this autumn. The Department will then consider its conclusions.

No capability has been removed from the approved Ground Based Air Defence requirement. The programme has, however, revised the planned acquisition approach in response to affordability pressures, evolving threats and delivery constraints.

The Land Deep Fires Programme (LDFP) is the Army’s modernisation programme for long-range surface-to-surface fires and comprises a portfolio of platform and munition projects designed to deliver a “one platform, many effectors” capability.

The principal projects include:

• the recapitalisation of the M270 Multiple Launch Rocket Systems (MLRS) launchers, and the associated Repair and Recovery Vehicles that are on contract to be upgraded;
• the acquisition of Wheeled Long Range launcher battery;
• the MLRS Family of Munitions comprising Guided MLRS (GMLRS) and Extended Range GMLRS;
• the Precision Strike Missile programme, together with the development of Long Range Area Effect alternative effectors, and
• Tactical Capability Trainers simulators, including a deployable system, and multi-spectrum camouflage system.

Collectively, these projects will enhance the Army’s ability to deliver precise, long-range fires, improve interoperability with allies, and provide a scalable deep fires capability from 70km to over 500km range.

Research and experimentation into a UK-developed Long Range Area Effect capability is being undertaken to develop the mechanisms and payloads required to deliver alternative effects from current and future weapon systems.
