The Boeing X-45 unmanned combat air vehicle is a concept demonstrator for a "next generation" of completely autonomous military aircraft, developed by Boeing's Phantom Works. Manufactured by Boeing Integrated Defense Systems , the X-45 was a part of DARPA 's J-UCAS project.

May 13, 2003 · Boeing planned the development and construction of two UCAV prototype air vehicles, X-45B, a larger air vehicle than the X-45A with an integrated avionics system, increased weapon delivery capacity and increased operating range and altitude.

Oct 28, 2009 · The first X-45A Unmanned Combat Air Vehicle (UCAV) technology demonstrator completed its sixth flight on Dec. 19, 2002, raising its landing gear in flight for the first time. The X-45A flew for 40 minutes and reached an airspeed of 195 knots and an altitude of 7,500 feet.

The X-45B design closely resembled the X-45A, but was somewhat larger to provide greater payload and range. However, before the first X-45B had been built, it was replaced by the larger X-45C (q.v. below), a common basic design for Air Force and Navy requirements.
