Overview
- The Ministry of Defence confirmed the UK will join the PrSM programme and has allocated £190 million from its Defence Investment Plan to fund initial procurement.
- PrSM is a supersonic surface‑to‑surface missile designed to reach up to 500 km and is currently produced by Lockheed Martin.
- The missile is fully compatible with the British Army’s upgraded M270A2 MLRS launchers so no vehicle modifications are required to field the system.
- First deliveries to the UK could begin in 2027 but that schedule and any UK production workshare depend on formal agreements with the United States and Australia.
- Officials say PrSM will quickly add a long‑range precision option that complements the One Way Effector drone and ground‑launched cruise missiles while the UK continues longer‑term European strike collaborations.
