The Lockheed Martin RQ-170 Sentinel is an American unmanned aerial vehicle (UAV) developed by Lockheed Martin and operated by the United States Air Force 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. Some images and details on the aircraft were released after Iran captured a RQ-170 in 2011.

The RQ-170 Sentinel was developed by Lockheed Martin's Skunk Works as a stealth unmanned aerial vehicle (UAV). Journalists have noted design similarities between the RQ-170 and previous stealth and UAV programs such as the RQ-3 DarkStar and Polecat. It is a tailless flying wing aircraft, with pods, presumably for sensors or SATCOMs, built into the upper surface of each wing. Few details of the UAV's characteristics have been released, but estimates of its wingspan range from 38 feet (11.5m) to 90 feet (27 m). In a December 2012 report, journalist David Axe stated that "20 or so" RQ-170s had been built.
