A rare U.S. Air Force RQ-170 “Sentinel” stealth surveillance drone was recently spotted returning to Roosevelt Roads Naval Station in eastern Puerto Rico. The drone returned after U.S. military strikes conducted overnight against targets in Venezuela. The RQ-170 Sentinel is a high-altitude, long-endurance unmanned aerial vehicle (UAV) of the United States. It was designed and manufactured by Skunk Works, a division of Lockheed Martin, for the United States Air Force (USAF). The drone is used for intelligence, surveillance, target acquisition, reconnaissance (ISTAR), and electronic warfare missions over target areas.
