Alliant Techsystems has teamed up with McDonnell Douglas to bid for a US Navy contract to develop the Extended Range Guided Munition (ERGM), or Hammer projectile, for the Naval Surface Fire Support programme. The ERGM is a 5in rocket-assisted ship-to-shore projectile, to be fired from a Mk45 gun, using global-positioning/inertial-navigation guidance.
