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 the 4th of 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 heat and radar signature. 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 Targetting (ALERT) system. The Avenger will use the same ground support infrastructure as the MQ-1 and MQ-9, including the ground controll station and existing communication networks.
