Written questions by Cartlidge.

With reference to page 48 of the Strategic Defence Review, published on 2 June 2025, when he plans to establish a Digital Warfighter group.

As stated in the referenced section of the Strategic Defence Review, the Digital Warfighter Group, at an Initial Operating Capability, will be established by July 2026.

With reference to recommendation 49 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, when will the first departmental review of the (a) SKYNET 6A and (b) SKYNET 6EC satellite communications programmes (i) commence and (ii) conclude.

The Skynet 6 programme undergoes formal quarterly reviews and is subject to regular review by the National Infrastructure and Services Transformation Authority, the next is scheduled for November 2025. Those reviews consider the resilience and operational relevance of the planned Skynet 6A and EC capabilities, which are also continuously assessed against projected operational demands and emerging threats. Where necessary, adjustments are then made across the entire Ministry of Defence Space enterprise to both ground- and space-based elements.

With reference to recommendation 49 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, how regularly will his Department review the (a) SKYNET 6A and (b) SKYNET 6EC satellite communications programmes.

The Skynet 6 programme undergoes formal quarterly reviews and is subject to regular review by the National Infrastructure and Services Transformation Authority, the next is scheduled for November 2025. Those reviews consider the resilience and operational relevance of the planned Skynet 6A and EC capabilities, which are also continuously assessed against projected operational demands and emerging threats. Where necessary, adjustments are then made across the entire Ministry of Defence Space enterprise to both ground- and space-based elements.

With reference to page 48 of the Strategic Defence Review, published on 2 June 2025, where the Digital Warfighter group will be based.

Our planning assumption is that the Digital Warfighter Group will be federated with the military commands. Hence the Group would be formed of multiple operational units, distributed across the UK.

With reference to page 79 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, whether he has a target date for forming a dedicated training programme for international defence engagement.

A training programme has been in place since the formation of the Defence Attaché & Loan Service Centre in 2016, preparing personnel to deploy into International Defence Engagement Roles across the world. Following the publication of the Strategic Defence Review, an internal review aiming to establish a Defence Diplomacy Career Stream is underway to further professionalise our people, which will include an examination of training provision. Until this review is complete, a target date for changes to the training pathway cannot be set.

With reference to recommendation 32 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, when the first review by senior Ministers from the National Security Council (Nuclear) committee on progress on the National Endeavour for delivering the UK’s nuclear deterrent will (a) begin and (b) conclude.

The National Endeavour to maintain and renew the United Kingdom’s nuclear deterrent is a whole of Government effort. The Ministry of Defence works closely with other Government departments, including the Cabinet Office, His Majesty’s Treasury, the Ministry for Housing, Communities and Local Government and the Department for Energy Security and Net Zero, to ensure its effective delivery. The National Security Council (Nuclear) remains committed to regularly reviewing progress on the National Endeavour. It receives comprehensive updates on delivery at least twice each year, with involvement from all relevant Departments.

With reference to recommendation 37 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, when he expects the Royal Navy’s hybrid carrier airwing to reach full operational capability.

The Hybrid Air Wing, underpinned by the Royal Navy’s approach to Maritime Aviation Transformation, represents the evolution of the Fleet Air Arm to a crewed-uncrewed mix of drones, fast jets, helicopters and one-way effectors that will deliver enhanced lethality and combat mass for North Atlantic Sea Control, Homeland Defence and Carrier and Littoral Strike. Fielding a suite of capabilities that puts Europe’s only 5th generation aircraft carriers at the heart of NATO, the Hybrid Air Wing will be Uncrewed Where Possible, Crewed Where Necessary. The Hybrid Air Wing is an iterative concept, with individual capabilities subject to spiral development to keep pace with the threat; this means that there will not be a single declaration of Full Operational Capability. The investment decisions to support Strategic Defence Review recommendations are being developed by the Ministry of Defence and will be published in the Defence Investment Plan.

With reference to page 79 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, what discussions he has had with the Secretary of State for Foreign, Commonwealth and Development Affairs on a dedicated training programme for international defence engagement since 2 June 2025.

The Secretary of State for Defence has not engaged in direct discussions with the Secretary of State for Foreign, Commonwealth and Development Affairs regarding this issue. The Defenvce Minister for the House of Lords is leading development of the Defence Diplomacy Strategy, which will direct activities in this field. Nonetheless, officials from both Departments continue to collaborate on a routine basis.

With reference to recommendation 32 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, which government departments will participate in the progress review of the National Endeavour for delivering the UK’s nuclear deterrent.

The National Endeavour to maintain and renew the United Kingdom’s nuclear deterrent is a whole of Government effort. The Ministry of Defence works closely with other Government departments, including the Cabinet Office, His Majesty’s Treasury, the Ministry for Housing, Communities and Local Government and the Department for Energy Security and Net Zero, to ensure its effective delivery. The National Security Council (Nuclear) remains committed to regularly reviewing progress on the National Endeavour. It receives comprehensive updates on delivery at least twice each year, with involvement from all relevant Departments.

With reference to recommendation 56 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, updated on 8 July 2025, what estimate he has made of the cost to the public purse of creating a single counter-intelligence unit.

The new Defence Counter Intelligence Unit’s (DCIU) mandate is to protect UK Defence from intelligence and espionage threats, at home and overseas, by bringing together expertise and specialist capabilities alongside the UK Intelligence Community. The DCIU will be led by a One Star equivalent Senior Civil Servant. We do not comment on the proportion of manpower figures or specific locations to safeguard national security and strategic Defence interests. The costs relating to the formation and running of the unit are ongoing and will form part of the Defence Investment Plan, due to be published later this year.

With reference to recommendation 5 of the Strategic Defence Review, published on 2 June 2025, when the first report of progress in establishing the fundamental capabilities of a core common platform will be submitted to the Secretary of State.

The fundamental capabilities of the core common platform set out within the Strategic Defence Review already exist and are being used today; however, they are not at the scale or delivering the integrated and innovative capabilities at the speed required to support the Integrated Force model. The regular progress reporting to Ministers will ensure that investment in these essential digital capabilities is closely monitored and prioritised through the Defence Investment Plan. The first progress report is due to be submitted to the Secretary of State in Autumn 2025.

With reference to recommendation 21 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, what recent progress his Department has made on developing a new Defence Diplomacy Strategy.

With the backdrop of the challenging global environment outlined in the Strategic Defence Review and the National Security Strategy, the Ministry of Defence is developing a new Defence Diplomacy Strategy, in coordination and consultation with other Government Departments. The Defence Diplomacy Strategy will prioritise the use of the Defence instrument in support of UK defence and wider foreign policy objectives. It will ensure that we are taking a coordinated, strategic and deliberate approach to protect and promote UK interests and enhance UK influence.This work is being led by the Minister of State for the House of Lords who is responsible for international relations and defence diplomacy.

With reference to recommendation 47 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, whether he plans on establishing a cost-sharing arrangement with NATO allies to expedite the procurement of E-7 Wedgetail aircraft.

The UK remains open to exploring all opportunities for future E-7 Wedgetail procurement, subject to the availability of funding.

With reference to paragraph 31 of the Strategic Defence Review, published on 2 June 2025, where the CyberEM Command will be based.

The 2* Defence Cyber and Electromagnetic Force will be headquartered in Corsham.

With reference to recommendation 15 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, how many recommendations he plans to make by October 2025 to help tackle (a) structural, (b) behavioural and (c) leadership barriers to the creation of a more (i) representative and (ii) meritocratic workforce by June 2026.

Raising our Standards has been established by Defence to address structural, behavioural, and leadership barriers. This work is key to operational delivery, recruitment, retention and driving forward an inclusive and safe culture. Raising our Standards has planned initiatives under five pillars: communications and influencing behaviour change, data and analytics, 100% action when tackling unacceptable behaviours, streamlined education and training, and developing world-class leaders. In response to recommendation 15 of the Strategic Defence Review regarding independent oversight of implementation, Raising our Standards is working to implement a refreshed External Challenge Panel by October 2025.

With reference to recommendation 26 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, what discussions his Department has held with the Department for Education on plans to expand in-school Cadet Forces by 30% by 2030.

The campaign to increase the Cadet Forces by 30% by 2030 (’30 by 30’) is backed by £70 million of extra funding. The diverse and unique nature of the individual Cadet Forces and the federated approach to delivery mean that this funding will be spread across the single Services, Ministry of Defence (MOD) Centre, and supporting organisations. Work is currently underway to establish how the 30% increase will be realised, and costings will be refined through the ongoing Defence Investment Plan process. The recommendation of the Strategic Defence Review covers both school and community-based Cadet Forces across the country. For a number of years, one focus for Cadet growth has been through the ongoing joint Department for Education (DfE)/MOD Cadet Expansion Programme (CEP) in schools. The CEP will form a key component of the new ‘30 by 30’ campaign, and our important engagement with DfE on the delivery of this discreet element will continue. We wish to grow Cadets in areas where the need is greatest. The MOD and the Ministry of Housing, Communities and Local Government (MHCLG) are working together to achieve this aim. In addition to our ’30 by 30’ campaign, MOD future growth plans will be aligned with areas with the highest deprivation levels and the weakest social infrastructure, including MHCLG’s Plan for Neighbourhoods programme places.

With reference to paragraph 31 of the Strategic Defence Review, published on 2 June 2025, what recent progress he has made on establishing the new CyberEM Command.

Design and implementation planning is well underway. The 4* Cyber and Specialist Operations Command has been launched as of 1 September 2025 and within it the 2* Defence Cyber and Electromagnetic Force is on schedule to be launched by the end of the year.

With reference to page 55 of the Strategic Defence Review, published on 2 June 2025, how many staff will be employed as part of the Defence Research and Evaluation organisation.

I refer the hon. Member to the answer I gave him on 26 June 2025, to Questions 59137, 59138, 59140 and 59143, and to the hon. Member for Huntingdon (Mr Obese-Jecty) to Question 59406. https://questions-statements.parliament.uk/written-questions/detail/2025-06-11/59137 This evolution of the Defence Science and Technology Laboratory is in the initial stages of planning and therefore requires substantial design work. The outcome of this, and subsequent details within, will be announced in due course.

With reference to recommendation 29 of the Strategic Defence Review, published on 2 June 2025, what proportion of the new CyberEM Command will be staffed by (a) military and (b) civilian personnel.

As stated by recommendation 51 of the Strategic Defence Review, the Defence Cyber and Electromagnetic Force “must be a ‘whole force’ endeavour, with its structure largely filled by a mixture of civilians and Reserves, given that greater expertise exists in the civilian sector.” Resourcing and military to civilian proportions of the Defence Cyber and Electromagnetic Force Headquarters are dependent on the outcome of the Defence Investment Plan. Submissions into the Defence capability investment governance process are ongoing and under discussion.

With reference to recommendation 25 of the Strategic Defence Review: Making Britain Safer: secure at home, strong abroad, published on 2 June 2025, what discussions he has had with the Secretary of State for Foreign, Commonwealth and Development Affairs on the review of the principle elements of the Integrated Global Defence Network since 2 June 2025.

The Secretary of State for Defence has not yet engaged in direct discussions with the Secretary of State for Foreign, Commonwealth and Development Affairs regarding the review of the principal elements of the Integrated Defence Network (IGDN). The review is currently in the early stages and FCDO officials are actively engaged.
