The General Atomics Avenger (formerly Predator C) is a developmental unmanned combat air vehicle built by General Atomics Aeronautical Systems for the U.S. military. Its first flight occurred on 4 April 2009. Unlike the previous MQ-1 Predator and MQ-9 Reaper (Predator B) drones, the Avenger is powered by a turbofan engine, and its design includes stealth features such as internal weapons storage, and an S-shaped exhaust for reduced infrared and radar signatures. The Avenger will support the same weapons as the MQ-9, and carry the Lynx synthetic aperture radar and a version of the F-35 Lightning II's electro-optical targeting system (EOTS), called the Advanced Low-observable Embedded Reconnaissance Targeting (ALERT) system. The Avenger will use the same ground support infrastructure as the MQ-1 and MQ-9, including the ground control station and existing communications networks.

On 27 October 2016, General Atomics flew an extended-range Avenger featuring wings extended by 3.2 m (10 feet) to 23.2 m (76 feet). The extended wings add about 1,000 kg (2,200 lb) of fuel totalling 4,600 kg (10,100 lb), extending endurance from 15 hours to 20 hours but reducing internal payload to 3,000 lb (1,400 kg). Since its first flight in 2009, the Avenger has completed more than 13,000 flight hours, reaching 11,000 hours in July 2016 and accumulating most of those hours within the past three years.
