The XQ-58A Valkyrie is a long-range unmanned aerial vehicle capable of high subsonic speeds. It was built by Kratos Unmanned Aerial Systems for the Air Force Research Laboratory's Low Cost Attritable Aircraft Technology (LCAAT) program and first flew on March 5, 2019. The XQ-58A demonstrator completed its inaugural flight at Yuma Proving Grounds in Arizona on March 5, 2019.

The Air Force is looking at relatively inexpensive, expendable drones like the Valkyrie as potential artificial-intelligence-driven autonomous platforms that could fly alongside and support manned fighter aircraft. This is the major focus of the Skyborg program.
