The Defense Advanced Research Projects Agency (DARPA) has awarded Boeing an additional $175 million to continue the X-45C portion of the Joint Unmanned Combat Air Systems (J-UCAS) Capability Demonstration Program.

This new award continues the demonstration program and adds a full demonstration of a new Autonomous Aerial Refueling technology.

The autonomous refueling effort will continue ongoing Air Force Research Laboratory and Boeing development activities and culminate in an in-flight X-45C refueling by a KC-135 tanker in 2010.

"With autonomous refueling, the X-45C provides an even longer sustained, lethal presence in hostile airspace holding enemy forces open to immediate surveillance or destruction," said David Koopersmith, Boeing J-UCAS X-45 vice president and program manager.
