Applied Physics Lab RPD-2 Paradel

The RPD-2 Paradel mini-RPV was built for the U.S. Naval Surface Weapons Center by the Applied Physics Laboratory of the Johns Hopkins University. It first flew in June 1975.

The RPD-2 was launched from a catapult and powered by a single McCulloch MC-101A piston engine. For recovery, a parachute system was installed, and airbags stowed in the wings softened the ground impact. The drone's equipment included a passive radar augmentation device in the nose and a Luneberg lens in a tailfin fairing.

Four RPD-2s were built, and they were used by the Navy to evaluate new ship-board fire control systems and gun ranging radars. This test program ended around 1979/80.
