Globe KD2G Firefly

The KD2G Firefly was Globe's first pulsejet-powered target. The XKD2G-1 of 1946 was similar to the piston-engined KDG-1 Snipe, but had a McDonnell 8" pulsejet and twin vertical tails. The KD2G-1 production version appeared in 1947 and had a 28V electrical system.

In 1950, Globe introduced the KD2G-2, which was powered by a different engine, the Solar PJ32 8" pulsejet. The KD2G series remained in use in the early 1950s, and the model eventually became the base for the development of the KD6G/MQM-40 Firefly, the most successful of Globe's target drones.
