Background: General Atomics' Gnat-750™ represents the first of a new generation of long endurance (greater than 24 hrs) UAVs evolving from the DARPA/Leading Edge Amber program. It has been the basis for the subsequent Altus, Predator/Horus, Gnat-750XP (eXtra Performance), and I-Gnat (Improved) models. Later model Gnats are capable of conducting air-to-air video relay and carrying external (wing) payloads. Its customers include the U.S. and Turkey.
