The Precision Strike Missile (PrSM) is a surface-to­surface, all-weather, precision-strike guided missile fired from the M270A2 Multiple Launch Rocket System (MLRS) and the M142 High Mobility Artillery Rocket System (HIMARS). The baseline missile (Increment 1) will be developed and fielded to engage a wide variety of point and imprecisely located targets at ranges greater than 400 kilometers (km). Primary emphasis for follow-on spirals is increased range, lethality, and engagement of time-sensitive, moving, hardened, and fleeting targets.


The PrSM provides field artillery units with a long-range and deep strike capability while supporting brigade, division, corps, Army, theater, joint/coalition forces, and Marine Air-Ground Task Forces in full, limited, or expeditionary operations. PrSM will replace the existing aged inventory of Army Tactical Missile Systems (ATACMS) and provide a new compliance for Insensitive Munitions and Cluster Munition policy.
