Developed by United Defense & Boeing, Linebacker (M6) Air Defense System – a variant of the Bradley fighting vehicle family integrates Stinger surface-to-air missiles on a modified M2-series vehicle. Unlike the standard Bradley, the Linebacker replaces the external TOW antitank missile launcher with a launcher carrying four ready-to-fire Stinger missiles. (The vehicle has a basic load of 10 Stingers.) The Linebacker’s sensor suite includes optical, TV and forward-looking infrared systems. The vehicle integrates into the Forward Area Air Defense (FAAD) system trough combat net data networking. Position reporting is provided autonomously, vie the Enhanced Position Location Reporting System (EPLRS).
