PrSM

America's next-generation tactical ballistic missile — a HIMARS/MLRS-fired deep-strike weapon that doubles ATACMS reach, adds an anti-ship capability, and made its combat debut against Iran in 2026.

Overview

The Precision Strike Missile (PrSM, pronounced "PRI-zim") is a surface-to-surface tactical ballistic missile developed for the US Army as the successor to the MGM-140 ATACMS. Fired from the same M142 HIMARS and M270A2 MLRS launchers, PrSM roughly doubles the range of its predecessor while fitting two missiles per pod where ATACMS carried one — yielding a substantial magazine advantage on every launcher. Increment 1 entered operational service in 2025, and the system saw its first combat employment in March 2026 during Operation Epic Fury against Iran. Later increments are expanding the envelope to moving maritime targets, modular payloads, and ranges exceeding 1,000 km, making PrSM the centerpiece of the Army's long-range precision fires modernization.
