Drones: Industry & DefenceBackground
The British Army is the United Kingdom's land warfare service, with around 73,000 regular personnel organised under Army HQ at Andover into combat formations including the 1st (UK) Armoured Division and 3rd (UK) Division. It has flown tactical drones since Hermes 450 deployments in Afghanistan from 2007, and its primary current UAV is the Watchkeeper WK450.
Task Force RAPSTONE is the Army's fast-track route for autonomous systems, run alongside the standard Defence Equipment Plan, a response to Ukraine having compressed acquisition timescales that once ran ten to fifteen years. The Army also assesses an Apache loyal-wingman drone concept under Project NYX, and is the designated end user for Project Corvus, Watchkeeper's planned replacement.
GEREON, bought through RAPSTONE, is the clearest test of that fast-track approach so FAR: a platform already proven in Ukrainian service, in British Army hands within months rather than years, and exercised alongside US forces at Fort Irwin in August 2026 , following the £45 million RAPSTONE production award in April.
The Army's fast-tracked buy proves itself
In April 2026 the British Army awarded ARX Robotics a production contract for the GEREON uncrewed ground vehicle through Task Force RAPSTONE, its fast-track route for autonomous systems outside the standard Defence Equipment Plan. ARX is investing £45 million in a Devon production line with manufacturing partner Supacat, scaling to 1,800 units a year. On 11 August, eight GEREON vehicles ran six continuous days alongside British troops at the US Army's Fort Irwin exercise, handling scouting, electronic warfare, counter-drone work, logistics and casualty evacuation with minimal human intervention.
For the Army, that trial is an early return on RAPSTONE's central bet: buying combat-validated, Ukrainian-tested platforms fast rather than running the ten-to-fifteen-year acquisition cycle that stalled programmes such as Watchkeeper.
