The General Atomics Avenger (formerly Predator C) is a developmental unmanned combat air vehicle built by General Atomics Aeronautical Systems for the United States 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 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 Targeting (ALERT) system. The Avenger will use the same ground support infrastructure as
