The Royal Navy will determine the weapons fit and payload capacity of the Common Combat Vessel as the programme progresses through its concept and assessment phases. The role, configuration and armament of the Common Combat Vessel will be considered in the context of the wider Hybrid Navy force design.

The Defence Investment Plan announced the development of the Type 91 uncrewed missile platform as part of the Royal Navy's future maritime integrated air and missile defence and strike capability. The number of platforms to be procured has not yet been determined. Detailed requirements, including fleet size, will be considered as the programme progresses through its concept and assessment phases.

The Stratus programme is currently in its Assessment Phase and the in-service dates for the system have therefore not been formally set and endorsed. However, the programme is anticipating fielding both the STRATUS LO Air Launched Deep Strike variant and the Surface Launched Anti-Ship variant in the early 2030s.

It is not Ministry of Defence policy to comment on the exact numbers of weapons procured, as disclosure of such detail could undermine operational security. The Defence Investment Plan funds a weapons programme that represents a substantial and sustained investment in the UK’s defence capability.

This will include significant numbers of both novel and existing/low and high-cost long-range weapons systems, spanning all domains and target sets. These capabilities will be sourced not only from UK industry – supporting domestic innovation and industrial resilience – but also through close collaboration with trusted allies, including partners in the United States and across Europe. This balanced approach ensures that the UK maintains access to cutting-edge technology while reinforcing interoperability and collective security with key international partners.

The current commitment of £405 million funds delivery and manufacture of the Capability One Sea Viper upgrade and the assessment phase of Capability Two. As of 26 June 2026, the project has spent £223.653 million. This is an increase of £5.053 million since I answered the same question asked by the hon. Member on 13 April 2026.

The Sea Viper air defence system is subject to regular trials and evaluation activity to ensure it remains safe, effective and fit for operational use. As he will recall from his time as a Defence Minister, the Ministry of Defence does not routinely publish details of individual trials, including their timing, as disclosure could prejudice operational security and capability assurance activity.

The cost of delivering and manufacturing Sea Viper Evolution Capability Two has not yet been negotiated. Capability Two remains in the assessment phase to inform future capability and investment choices, and the associated delivery and manufacturing costs will be negotiated in due course.

The Lightweight Multi-Role Missiles (LMM) ordered this year to replenish the UK stockpile will be delivered, and available for use if required, by March 2027.

I refer the hon. Member to the response I gave to him on 8 June 2026 in response to Question 6453 which remains extant:

A review of credible options to fulfil the Land Deep Fires requirement has been undertaken and is being considered as part of the Defence Investment Plan.

Officials have engaged with industry representatives during the Department’s review of credible options to fulfil the Land Deep Fires requirement.

A review of credible options to fulfil the Land Deep Fires requirement has been undertaken and is being considered as part of the Defence Investment Plan. No final decision on procurement has yet been taken.

I can confirm the Ministry of Defence has placed orders for Aster, Advanced Short Range Air-to-Air Missiles, Lightweight Multirole Missiles and Advanced Precision Kill Weapon System missiles since 5 July 2024. Deliveries of Common Anti-Air Modular Missiles, which are used by the Land Ceptor system, continue under an extant contract. As a former Defence Minister, the hon. Member will understand that I am withholding further details, including quantities ordered and delivered, for reasons of operational security.
