The US Department of Defense has approved the sale of four MQ-9 Reaper unmanned aircraft to Spain for $243 million.

The deal would include four MQ-9 Block 5 drones, 20 embedded Global Positioning Systems, two mobile ground control stations, five targeting systems and five radars, the Defense Security Cooperation Agency said in a statement.

The General Atomics MQ-9 Reaper (formerly named Predator B) is an unmanned aerial vehicle (UAV) capable of remote controlled or autonomous flight operations, developed by General Atomics Aeronautical Systems (GA-ASI) primarily for the United States Air Force (USAF). The MQ-9 and other UAVs are referred to as Remotely Piloted Vehicles/Aircraft (RPV/RPA) by the USAF to indicate their human ground controllers.

The MQ-9 is the first hunter-killer UAV designed for long-endurance, high-altitude surveillance.In 2006, the then–Chief of Staff of the United States Air Force General T. Michael Moseley said: “We’ve moved from using UAVs primarily in intelligence, surveillance, and reconnaissance roles before Operation Iraqi Freedom, to a true hunter-killer role with the Reaper.”
