The Globe KD6G Firefly was an American target drone, built by the Globe Aircraft Corporation for operation by the United States Navy during the 1950s and early 1960s.

Design and development

The design of the KD6G was based on the earlier Globe KD2G Firefly target drone, featuring a mid-wing configuration with a twin-fin empennage, but instead of a pulsejet powerplant as in the KD2G the KD6G was fitted with a single piston engine in a tractor configuration. Launched via catapult, the KD6G was radio-controlled during flight, and, if it was not shot down in the course of its mission, would be recovered via parachute.

Operational history

First flying in prototype form in 1951, the KD6G proved successful and was ordered into production in two forms, the KD6G-1 with a McCullough O-100 engine, and the KD6G-2 with a Kiekhaefer V-105 powerplant. Used extensively by the United States Navy during the 1950s in the gunnery training role, the KD6G-2 was redesignated in 1963 in the new unified missile sequence, becoming the MQM-40A before being retired soon thereafter.
