Lockheed Martin PrSM

By 2016, the U.S. Army had formulated its LRPF (Long Range Precision Fires) requirement for a guided missile to replace the MGM-140 ATACMS. Initially, Lockheed Martin, Raytheon and Boeing were competing for a contract, but the latter two withdrew in early 2020. The missile itself was labeled Precision Strike Missile (PrSM), and the first test flight of Lockheed Martin's PrSM occurred in December 2019.

PrSM

Thanks to an advanced solid rocket motor, the PrSM can fly farther and faster than the MGM-140, even though it is significantly sleeker. The latter feature enables the carriage of two missiles per launch pod instead of only one as for ATACMS. PrSM is compatible with the widely used M270A2 MLRS (Multiple Launch Rocket System) and M142 HIMARS (High Mobility Artillery Rocket System) launch vehicles. The missile can be used at ranges betweem 60 km (37 miles) and at least 500 km (310 miles) (probably more), and has a GPS guidance system for high precision against stationary targets. Later upgrades envision an additional multi-mode seeker for use against moving targets.

PrSM

At the end of 2023, Lockheed Martin delivered the first EOC (Early Operational Capability) PrSM all-up rounds to U.S. Army operational units. At least 300 PrSM missiles are already on order from the Army until FY2025.
