Raytheon Company's Small Tactical Munition Phase II has successfully completed the first
guided flight test after scoring a direct hit on a target. "STM Phase II is ideally suited to weaponize Shadow-class unmanned aircraft systems and
counterinsurgency aircraft because STM is a mature, precise and affordable weapon," said
Dr. Thomas R. Bussing, vice president of Advanced Missiles and Unmanned Systems for
Raytheon Missile Systems. "STM gives warfighters flexibility because it enables them to
engage moving and static targets with minimal collateral damage." During the February test, a Raytheon Cobra unmanned aircraft system released the STM
Phase II in flight. After safely separating from the UAS, the weapon used both GPS/INS and
semi-active laser to guide to the target. STM Phase II is a new 13.5-pound, 22-inch long, precision-guided, gravity-dropped bomb
specifically designed for employment from manned and unmanned aircraft systems. STM Phase II is more than 2 inches shorter than the Phase I design and has foldable fins
and wings, enabling two weapons to be placed inside the U.S. military's common launch
tube. STM Phase II's modular assembly will make the system simpler to manufacture on a
large scale.
