Background

The British Army is the United Kingdom's land warfare service. Its current uncrewed procurement spans ground vehicles and the replacement of the Watchkeeper drone fleet, placing autonomous systems within its force-development work. The September AR5 award made the Watchkeeper replacement a defined acquisition programme.

Task Force RAPSTONE provides a faster route for the Army to acquire autonomous systems. In April 2026, RAPSTONE backed the GEREON purchase and a UK production line with Supacat.

The Army's August 2026 Fort Irwin trial showed how that route can connect procurement to field use. British troops operated GEREON vehicles across reconnaissance, electronic warfare, counter-drone, logistics and casualty-evacuation tasks.

Key Issues
Drone replacement

The Army replaces Watchkeeper

On 16 September, the Ministry of Defence committed up to £400m for Tekever's AR5, the aircraft selected to replace the British Army's Watchkeeper fleet. Six aircraft form the first delivery, placing the Army at the receiving end of a procurement decision shaped by its need for a successor system.

The route to that award had narrowed by July. Project Corvus received no compliant bids, leaving the ministry to negotiate directly with Tekever on a deal reported at £336m before VAT. For the Army, the outcome turns a replacement requirement into a defined programme after the Watchkeeper era.

Ground robot procurement

RAPSTONE accelerates robot fielding

In April, the British Army used Task Force RAPSTONE to procure ARX Robotics' GEREON uncrewed ground vehicle. The contract supported a £45m UK production line with Supacat and capacity of up to 1,800 vehicles a year, tying the Army's requirements to domestic manufacture.

On 11 August, eight GEREON vehicles worked alongside British troops for six continuous days at Fort Irwin. They performed scouting, electronic warfare, counter-drone tasks, logistics and casualty evacuation. The exercise gave the Army an operational test of the fast-track route, rather than only a factory commitment.

Common Questions
What drones does the British Army use?
The British Army's primary tactical UAV is the Watchkeeper WK450, which is being replaced via the Project Corvus competitive tender (£130-156M, 2026). The Army is also the end user for the Project NYX Apache loyal-wingman programme, targeting an operational variant by 2030.Source: Lowdown drones-industry-defence Update 10
How many soldiers are in the British Army?
The British Army has approximately 73,000 regular personnel, plus a significant reserve component.Source: Lowdown drones-industry-defence
What autonomous ground vehicles is the British Army buying?
The British Army awarded a GEREON uncrewed ground vehicle contract to ARX Robotics UK via Task Force RAPSTONE in April 2026. ARX is building a UK production line with Supacat capable of up to 1,800 units per year, backed by a £45 million investment.Source: event
What is the British Army's Project Corvus?
Project Corvus is the British Army's competitive tender to replace the Watchkeeper WK450 tactical UAV. The contract value is estimated at £130-156 million with an initial five-year term from May 2026; confirmed bidders include Quantum Systems and Anduril (UK).Source: event
What is Task Force RAPSTONE?
Task Force RAPSTONE is the British Army's fast-procurement mechanism for autonomous systems, operating outside the standard Defence Equipment Plan. It was used to award ARX Robotics a GEREON UGV production contract in April 2026.Source: event
