The Radioplane Co. RP-5A / OQ-2A / TDD-1 started rolling off the production line at the San Fernando Valley Airport in June 1941. The OQ-2A was catapult-launched and was recovered under a 24-foot diameter parachute. Conventional landing gear cushioned the landing impact. After launch, gunnery target missions were flown by a ground controller using a “beep” box, so called because of the tones transmitted to the target’s control system. Radioplane Co. produced a total of 14,891 drones for the USAAF and USN from 1941 through 1945.
