This test marks the third time an AIM-9X has engaged moving surface targets. A U.S. Air Force F-16 launched an AIM-9X and sank a maneuvering boat in April 2008, and a U.S. Air Force F-15C fired an AIM-9X and destroyed a fast-moving armored personnel carrier in March 2007. "With a software upgrade, AIM-9X retains its air-to-air capabilities and gains an air-to-surface capability," says Harry Schulte, Raytheon Missile Systems vice president of Air Warfare Systems. "AIM-9X now has the potential to take on an additional mission at a very affordable cost." More than 400 Raytheon employees design and build the AIM-9X Sidewinder missile in three locations: Tucson, Ariz.; Andover, Mass.; and Goleta, Calif. Other technology firms across the U.S. manufacture components for the AIM-9X.
