The Honeywell GG440 Golden Gnat rate gyroscope was a common feature of Cold War-era military guidance equipment. The GG440 and its direct descendants were used in the F-104, F-4, F-15 and F-16 aircraft, as well as numerous radar and missile systems.
It appears that Honeywell no longer produces these devices, and legacy support is provided by the military contractor US Dynamics.
