The Lockheed Martin RQ-170 Sentinel, nicknamed Wraith,^[2] is an American unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force (USAF) for the Central Intelligence Agency (CIA). While the USAF has released few details on the UAV's design or capabilities, defense analysts believe that it is a stealth aircraft fitted with aerial reconnaissance equipment. Introduced in 2007, it was deployed to Afghanistan in late 2007, and to South Korea two years later, in September 2009. Some images and details of the aircraft were released after Iran captured an RQ-170 in 2011. It has a flying wing design, and uses a single engine, speculated to be either a General Electric TF34 turbofan or a Garrett TFE731.
