Written questions by Cartlidge.

With reference to his Department's press release entitled Billion-pound helicopter deal secures 3,300 British jobs, boosts battlefield kit and unlocks up to £15 billion in UK exports, published on 2 March 2026, whether he plans to deliver the new medium-lift helicopter as an uncrewed capability in the (a) current or (b) next Parliament.

The New Medium Helicopter (NMH) has been procured with an open architecture that will enable integration with crewed and uncrewed systems as future requirements and funding are defined by Defence. This approach is supported by the wider benefits delivered through the £1 billion NMH contract, which secures thousands of skilled UK jobs, significantly increases UK industrial workshare, and establishes Yeovil as Leonardo’s global centre of excellence for autonomous helicopter technology. These investments strengthen the UK’s long-term capacity to develop and exploit emerging uncrewed aviation capabilities. While this provides a clear pathway for future interoperability, the platform will not be delivered as an uncrewed capability in this Parliament or the next.

With reference to his Department's press release entitled Billion-pound helicopter deal secures 3,300 British jobs, boosts battlefield kit and unlocks up to £15 billion in UK exports, published on 2 March 2026, how much additional money will be allocated to Proteus.

Given the hon. Gentleman’s former role as the Minister for Defence Procurement he will be aware of the details of the New Medium Helicopter (NMH) contract. We have improved upon that deal, renewing and strengthening MOD’s relationship with a key industry partner. Aside from the contract to supply 23 AW149 aircraft, Leonardo have agreed that future military international orders will be built in the UK, with an increased workshare for the UK above 40%. Moreover, Leonardo have also agreed to make the United Kingdom the home of exports for the AW149, with the potential for over £15 billion of export opportunities over the next decade. In addition, Leonardo have agreed to make Yeovil their global centre of excellence for autonomous helicopters, building on the ongoing successful development of Project Proteus. The £1 billion deal with Leonardo for NMH does not include funding committed to Proteus. Proteus is a £60 million programme, with information on the additional funding to be published in due course.

With reference to his Department's press release entitled Enemy weapons detector in the hands of soldiers five years early, published on 14 February 2026, how many SONUS systems have been procured as of 24 February 2026.

The SONUS system is an Acoustic Weapon Locating capability part of a wider programme which is delivering the next generation of Weapon Locating Sensors to enhance the capabilities of the 5th Regiment Royal Artillery. In January 2026, Leonardo UK was awarded a contract to deliver eight SONUS Acoustic Weapon Locating Sensors to the British Army. This state-of-the-art technology will play a critical role in enhancing the Army’s ability to detect and locate weapon systems with precision and efficiency. As part of the delivery schedule, 5th Regiment Royal Artillery will receive two sensors by the end of FY 2025-26, enabling the achievement of Minimum Deployable Capability. The remaining six systems will be delivered in FY 2026-27, achieving the Full Deployable Capability before year end.

What estimate has he made of the total cost of issuing operational tour bonuses in each remaining financial year of the current Parliament.

Operational Allowance (OA) is a location‑driven allowance that recognises increased and enduring danger in Specified Operational Locations (SOLs). The number of Service Personnel in receipt of OA reflects the number of Service Personnel deployed to SOLs. SOL status is kept under regular review and is considered by the Permanent Joint Headquarters’ (PJHQ) Operational Records Board on a six‑monthly basis. As operational activity varies according to Defence commitments, entitlement to OA fluctuates accordingly. It is not possible to forecast how many individuals will receive OA in future financial years, nor the cost. Forecasting would require assumptions about the scale, location, and duration of future operational activity.
