TUCSON, Ariz., 6 April 2012. Raytheon Co.'s (NYSE: RTN) Small Tactical Munition Phase II scored a direct hit on a target during the weapon's first guided flight test.
During the February test at Yuma Proving Ground, Ariz., a Raytheon Cobra unmanned aerial vehicle (UAV) released the STM Phase II in flight. After safely separating from the UAV, the weapon used both GPS/INS and semi-active laser to guide to the target.

STM Phase II is a 13.5-pound, 22-inch long, precision-guided, gravity-dropped bomb specifically designed for employment from manned and unmanned aircraft systems.
The STM Phase II has both GPS/INS and digital semi-active laser guidance.
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 also make the system easier to manufacture on a large scale.
