Precision Strike Missile (PrSM)
Print Friendly, PDF & Email


The Precision Strike Missile (PrSM) will be a surface-to-surface, all weather, precision-strike guided missile fired from the M270A1 Multiple Launch Rocket System (MLRS) and the M142 High Mobility Artillery Rocket System (HIMARS). The baseline missile, which will be developed and fielded to engage a wide variety of targets at ranges up to 499 km, will emphasize imprecisely located area and point targets. Primary emphasis for follow-on spirals will be on increased range, lethality and engagement of time sensitive, moving, hardened and fleeting targets.


The PrSM will destroy/neutralize/suppress targets at ranges from 70-400-plus km using missile-delivered indirect precision fires. PrSM provides field artillery units with 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 non-Insensitive Munitions and Cluster Munition policy compliant Army Tactical Missile Systems (ATACMS).


  • Replaces ATACMS and doubles rate-of-fire with two missiles per launch pod
  • 400-plus km ballistic missile with a cluster munition compliant payload
  • Attacks critical and time-sensitive area and point targets
  • Maintains or improves accuracy in partial Global Positioning System (GPS)-denied environments; plan for M-Code GPS integration
  • Insensitive Munition compliant system
  • Launcher compatibility with M270A1 MLRS and
    M142 HIMARS
  • Technology upgrades via Open Systems Architecture
  • Growth capabilities for follow-on spirals
  • Includes Cyber Security requirements
