ADM-20 Quail
The B-52 could carry eight McDonnell Douglas ADM-20 Quail air-launched cruise missile decoys in its bomb bay. The unarmed drone could be programmed to make altitude and heading changes, and carried radar reflectors and an infrared burner to trick enemy air defense radars into thinking the cruise missiles were American bombers. Initially equipped in 1961, advances in ground radar would render the Quail obsolete by the time it was removed from service in 1978.
