The Tigercat had a less than memorable Navy career, with its longest service
providing drone control, ironically enough of drone F6Fs.
When the F7F-2N’s were retired for the later versions,
several were converted to high performance airborne control aircraft. Major changes to the airframe included a raised second
seat behind the pilot for the controller. A Bearcat canopy was married to the fuselage. All guns were deleted, and an ADF
antenna housing was mounted to the upper nose section. Some aircraft were fi tted with under wing pylons for the launch of
KD2G-2 anti-aircraft drones. The drones were powered by pulse jets similar to those used on Germany’s V-1. Another
obvious change for the F7F-2D was the color scheme. It was designed to provide maximum visibility during gunnery practice.
Glossy blue fuselage and nacelles, bright yellow wings and empennage, red rudder, and red bands around the wings outboard
of the nacelles. The F7F-2D drone controller was retired from service in September of 1957.
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.

The first radio controlled aircraft
The F7F-3K (Bu No 80411) was a radio controlled drone, developed
by bell aircraft at MCAS Cherry Point on a Navy contract on August 8th 1946.
During the demonstration the aircraft had to land with its
wheels up and sustained major damage.
