EAST HARTFORD, Conn., Jan. 8 (UPI) -- The follow-on naval variant of Northrop Grumman's X-47 unmanned aerial vehicle has been unveiled for the U.S. Navy.
U.S. companies Northrop Grumman and X-47 engine designer Pratt & Whitney unveiled the first X-47B UAV as part of the Navy's Unmanned Combat Air System Carrier Demonstration program.
The announced unveiling marks a significant milestone for the X-47B development, showing the Navy a structurally complete X-47B. Officials say the first flight of the X-47B, powered by a Pratt & Whitney F100-PW-220U engine, is expected to take place in 2009, with aircraft carrier trials at sea planned for late 2011.
"To see this revolutionary unmanned combat air system is truly a proud moment," Michael Ondas, Pratt & Whitney UCAS-D program manager, said in a statement.
"To see the tangible results of our design and development efforts is very rewarding. We are proud to celebrate this accomplishment with Northrop Grumman, the U.S. Navy and the entire X-47B team."
