In 1942, McDonnell developed the Katydid jet-powered target drone under contract from the U.S. Navy. The prototypes were designated XTD2D-1, and were followed by an unknown quantity of TD2D-1 production drones.
The TD2D-1 was powered by a McDonnell 8" pulsejet, and could be either ground-launched by catapult or air-launched from under-wing racks on PBY Catalina aircraft. The Katydid was gyro-stabilized, could be controlled by radio commands and was recovered by parachute.
In 1946, the XTD2D-1 and TD2D-1 were redesignated as XKDD-1 and KDD-1, respectively. Later in 1946, the Navy changed McDonnell's manufacturer code letter from "D" to "H", and the KDD-1 was redesignated again as KDH-1.
Note: Data given by several sources show slight variations. Figures given below may therefore be inaccurate!
Data for KDH-1:
|Length||3.40 m (11 ft 2 in)|
|Wingspan||3.71 m (12 ft 2 in)|
|Speed||400 km/h (250 mph)|
