 The Desert Hawk was designed by Lockheed Martin's Skunk Works for the Air Force FPASS (Force Protection Airborne Surveillance System) Program on a quick-reaction contract issued late in the winter of 2002, with the first system delivered in the early summer.It was designed quickly because it leveraged heavily off of technology and design studies developed for the MicroStar MAVs.However, in 2007, the US Air Force FPASS office switched all of their UAV systems over to the RQ-11 Raven B.
