The AQM-38 was an American target drone, developed by the Radioplane Division of the Northrop Corporation during the 1950s. Extensively used for surface-to-air missile training, over two thousand of the drones were built during its production run, with the missile continuing in use with the United States Army and United States Navy for almost twenty years. ==Design and development== Following flight trials of the XKD4R target drone, developed for the United States Navy, Radioplane redesigned the aircraft into an improved version, designated RP-76, first flying in 1959.〔Parsch 2003a〕 Compared to the XKD4R, the RP-76 had redesigned wing fairings, with the vertical control fin being moved to the underside of the missile, as opposed to being on top.〔Parsch 2003b〕 The RP-76 was designed to fly a pre-programmed trajectory on autopilot, with radio command guidance being optional.〔 As with the XKD4R, control was provided by three fins located forwards on the body of the craft. A Luneberg lens was included to augment the drone's radar signature, and recovery at the end of the flight was by parachute.〔
