Task Force RAPSTONE is a British Army fast-procurement mechanism for uncrewed ground vehicles. It sits within the Army's acquisition organisation and is intended to shorten the route from a defined requirement to a contract. Its April 2026 GEREON award showed the mechanism operating on a major ground-robot purchase.

The mechanism favours UK manufacturing capacity over the nationality of a prime contractor. ARX Robotics, a German firm, secured its award through a UK production partnership with Supacat rather than by becoming a British company.

That approach makes RAPSTONE relevant to the Army's effort to build domestic capacity for ground robotics while drawing on European suppliers. Its significance rests on whether repeat awards can turn fast procurement and UK assembly into a durable acquisition route.

Ground robot procurement

RAPSTONE opens a British robot line

In April 2026, RAPSTONE provided the British Army route for ARX Robotics' GEREON contract. The award supported a £45m production line with Devon manufacturer Supacat, planned to make up to 1,800 vehicles a year.

By 11 August 2026, GEREON vehicles had completed a six-day trial alongside British troops at Fort Irwin, performing scouting, electronic warfare, logistics and casualty-evacuation tasks. For RAPSTONE, the trial gave its first prominent procurement award an operational test beyond the factory plan.

Common Questions

RAPSTONE fast-tracks its first UGV award

How did the GEREON robot perform in US Army trials?

What contract did Task Force RAPSTONE award ARX Robotics?

Task Force RAPSTONE awarded ARX Robotics UK its first GEREON UGV contract on 16 April 2026, backing a £45m UK manufacturing investment with capacity for up to 1,800 robots a year and at least 90 skilled jobs, with Supacat as production partner.Source: ARX Robotics / GOV.UK

How does the British Army fast-track robot procurement work?

Task Force RAPSTONE constrains programme scope and bypasses extended staff-work phases to accelerate uncrewed ground vehicle procurement. It accepts in-country final assembly by foreign firms such as ARX Robotics (Germany) working with UK partners such as Supacat.Source: ARX Robotics / GOV.UK

What is RAPSTONE?

A UK Army programme for cheap first-person-view attack drones and interceptor drones, given a further £50 million under the 29 June 2026 Defence Investment Plan.Source: event

Is RAPSTONE the same as the Royal Navy's Task Force RAPSTONE?

No, they share a name only; RAPSTONE the drone programme is an Army initiative, distinct from the Navy task force.

Why is the UK Army buying more FPV drones?

To copy Ukraine's wartime procurement model, which fields roughly 200,000 FPV drones a month against Russian forces.

How much money does RAPSTONE get?

£50 million over 12 months, part of a wider £650 million allocation for expendable autonomous systems in the £5bn Defence Investment Plan.
