    The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...

    The Vertical Take-Off and Landing Experimental Aircraft (VTOL X-Plane) program was an American research project sponsored by the Defense Advanced Research Projects Agency (DARPA). The goal of the program was to demonstrate a VTOL aircraft design that can take off vertically and efficiently hover, while flying faster than conventional rotorcraft ...
