The General Atomics GNAT is a reconnaissance UAV developed in the United States in the late 1980s and manufactured by General Atomics Aeronautical Systems Inc. (GA-ASI). As initially designed, it was a simplified version of the LSI Amber intended for foreign sales. The GNAT 750 made its first flight in 1989.The GNAT 750's configuration was similar to that of the Amber, except that the GNAT 750's wing was mounted low on the fuselage, instead of being mounted on a pylon on top.
