This is the XKD5G-1, a pulse-jet powered U.S. Navy target drone. The pulsejet, with a thrust of 170 pounds, was mounted externally as in the German V-1 missile of World War II but of smaller size. The XKD5G-1 had a speed of 300 knots and could be recovered by parachute for re-use. The XKD5G-1 originated in 1949, with tests undertaken at the Naval Air Test Station, Point Mugu, California.
By 1951-1952, requirements of drones increased in terms of speed, and pulsejets were not effective beyond 30,000 feet. Further development of the XKD5G-1 was thus abandoned. The drone was one of the last uses of pulse-jets by the U.S. military. This XKD5G-1 was donated to the Smithsonian in 1966 by the U.S. Navy.
