The Lockheed Martin X-44 MANTA (Multi-Axis No-Tail Aircraft) was an American conceptual aircraft design by Lockheed Martin that has been studied by NASA and the U.S. Air Force. It was intended to test the feasibility of full yaw, pitch and roll authority without tailplanes (horizontal or vertical). Attitude control would rely purely on 3D thrust vectoring.[1] The aircraft design was derived from the F-22 Raptor and featured a stretched delta wing without tail surfaces.[1]
