Design and development
The KD2G was a mid-wing, twin-tailed aircraft of similar design to the KDG Snipe which Globe was already supplying to the Navy. A single McDonnell PJ42 pulsejet engine was mounted atop the rear of the fuselage. The fuselage was constructed of steel tubing with a duralumin monocoque covering; dural was also used for the flying surfaces. The KD2G was equipped with radio control with an effective range of 6,000 yards (5,500 m); it could be launched using a catapult, or launched aerially from JD-1 or F7F-2D aircraft. Recovery, if it survived its mission, was by a 32-foot (9.8 m) diameter parachute; the Firefly was designed to be able to float for up to 15 minutes in the event of a water landing.
Operational history
First flying as the XKD2G-1 prototype during 1946, the KD2G-1 entered service with the United States Navy during 1947. The improved KD2G-2, powered by a Solar PJ32 pulsejet, began production in 1950; it was the first successful jet-powered target drone to be developed following the end of World War II. The KD2G remained in service through the mid-1950s, being replaced by the KD6G.
