Whether there will be an equal level of single Service representation for the (a) Military Strategic Headquarters and (b) its supporting staff.

It is too early to specify the overall staffing requirements and Service representation levels for the new organisational structure created as part of Defence Reform. This will be subject to refinement as planned implementation continues, and in response to operational and policy requirements as they emerge. It is, however, anticipated that the guiding principle of military post rotation within the single Services will continue to apply in the new structure.

What recent assessment he has made of the progress of the Ground Based Air Defence programme.

The Land Ground Based Air Defence (GBAD) programme strives to modernise Defence’s ground-based air defence capabilities in the face of rapidly developing threats and is a high priority for the Army. This includes the development of an integrated layered air defence system comprising countering Small Air Targets, Short and Medium Range Air Defence. The programme is now working towards an Initial Operating Capability of Medium Range Air Defence for warfighting by July 2026. This includes two Surface-to-Air Missile Operations Centres, and two enhanced Wireless Enabled Network sets. By June 2027, a further 800 Thales (Belfast) lightweight multi role missiles (LMM) will also be procured. The programme has begun to deliver Counter-Uncrewed Aerial Systems (C-UAS) capability for dismounted close combat forces, albeit in relatively low numbers. The focus is now switching to higher level UAS detect and non-kinetic systems, and upgrades to vehicle mounted weapon systems to enable them to engage UAS.

With reference to his Written Ministerial Statement of 1 April 2025 on Defence Reform, HCWS573, whether the National Armaments Director Group is a non-departmental public body.

No.

What recent progress his Department has made on the Land Intelligence, Surveillance, Target Acquisition and Reconnaissance programme.

The Land Intelligence, Surveillance, Target Acquisition and Reconnaissance (ISTAR) programme will deliver a suite of new sensor systems and enable a digitalised Army, by fusing data sources and ensuring capacity for effective and faster decision-making. At the core of the programme is project ZODIAC, which will provide the digital infrastructure required to network our sensors into a fused intelligence picture that is displayed across the network and automate our intelligence collection and analytical processes. The ZODIAC Minimum Viable Product was delivered to 3 (UK) Division in 2024. Following a period of continuous development, enabled by the agile nature of the project, it will deliver the backbone of the Divisional ISTAR system for the forthcoming Warfighter Exercise in the US in May 2025.The TIQUILA project will provide a new Uncrewed Air System (UAS) to support Brigade and Divisional Operations. It has now achieved its Initial Operating Capability, delivering three trained and equipped detachments into the Joint Aviation Command (JAC). TIQUILA is on schedule to reach Full Operating Capability by mid-2026, which will deliver a further 21 detachments that are fully integrated into the ZODIAC system. Under TIQUILA's spiral upgrade programme, platforms will be fitted with resilient hardware and Long-Range Antennas, enabling them to operate in Global Navigation Satellite Systems-denied environments with greater reach.
