The General Atomics MQ-1 Predator is an American remotely piloted aircraft (RPA) built by General Atomics and used primarily by the United States Air Force (USAF) and Central Intelligence Agency (CIA). The USAF describes the Predator as a “Tier II” MALE UAS (medium-altitude, long-endurance unmanned aircraft system). The UAS consists of four aircraft or “air vehicles” with sensors, a ground control station (GCS), and a primary satellite link communication suite. Initially conceived in the early 1990s for aerial reconnaissance and forward observation roles, the Predator carries cameras and other sensors but has been modified and upgraded to carry and fire two AGM-114 Hellfire missiles or other munitions. The aircraft, in use since 1995, has seen combat in war in Afghanistan, Pakistan, the NATO intervention in Bosnia, Serbia, Iraq War, Yemen, Libyan civil war, the intervention in Syria, and Somalia. Powered by a Rotax engine and driven by a propeller, the air vehicle can fly up to 460mi to a target, loiter overhead for 14 hours, then return to its base. It has a maximum speed of 135mph, can fly as high as 25,000ft and can stay in flight up to 24 hours.
