Also known as
  • PrSM
  • Precision Strike Missile Increment 1

The Precision Strike Missile, commonly abbreviated PrSM, is Lockheed Martin's long-range surface-to-surface missile for U.S. Army field artillery. Built for HIMARS and M270 MLRS launchers, it carries two rounds per launch pod, extends deep-strike reach beyond ATACMS, and moved from first delivery in December 2023 to documented combat use against Iranian targets in March 2026.

U.S. forces used PrSM from HIMARS during Operation Epic Fury against Iranian targets, marking its first documented combat deployment after fielding in 2023.

Documented Launch Profile

Lockheed's PrSM product card describes a two-round-per-pod missile with HIMARS and M270 MLRS compatibility. The public test record now covers the first flight test, a soldier-led HIMARS launch, and first-time M270A2 integration.

M142 HIMARS, Wheeled multiple rocket launcher and tactical missile launcher, ArtilleryArtilleryM142 HIMARSWheeled multiple rocket launcher and tactical missile launcherThe M142 HIMARS is a U.S.-built wheeled rocket and tactical missile launcher produced by Lockheed Martin for mobile precision fires. It carries one six-rocket pod, two PrSM missiles, or one ATACMS missile, uses a five-ton truck chassis with an armored cab, and can deploy by C-130-class airlift. Lockheed Martin reported the 750th launcher delivery in November 2025, while its combat record spans U.S. operations and Ukrainian long-range fires against Russian forces.

Its family spans M39/Block I cluster-warhead missiles, extended-range Block IA rounds, and later unitary-warhead variants, with documented combat use by U.S. forces in the 1990 Gulf War and 2003 Iraq War, transfer to Ukraine for long-range strikes, and later U.S. maritime-strike use during Operation Epic Fury.
