Overview
- Three UK firms — MBDA UK, MGI Engineering and Rotron Aerospace — fired prototype ground‑launched systems in spring 2026 at a Ministry of Defence range in the Hebrides with only minor technical hiccups.
- Project Brakestop requires designs to reach about 500 km, carry roughly 225 kg warheads, cost near £400,000 per unit and be producible at about 20 units per month.
- The weapons were built without US components so they do not trigger US International Traffic in Arms Regulations, which can restrict how and where systems with American parts are used or exported.
- The programme has moved into a second development phase with follow‑on contracts and further trials planned and UK officials say initial deliveries to Ukraine could happen within months to roughly a year if testing and production scale-up succeed.
- The project blends civilian engineering know‑how, such as Formula 1 aerodynamics and carbon composites, with fast prototyping to boost UK industrial resilience and to give Kyiv direct access to deep‑strike capability without relying on allied approvals.
