The premise behind the X-44 Manta was to build an even better stealth fighter than the F-22 Raptor, and in no uncertain terms, that is precisely the stated aim of the NGAD program. However, it’s also important to note that the X-44 concept was born in 1999, making its design just about as dated as the F-35 and the fighters NGAD will be tasked with killing–the Chinese J-20, and Russian Su-57,Way back in 1999, Lockheed Martin had a plan to field a delta-shaped stealth fighter that skipped the need for a conventional tail section, in the F-22-based X-44 Manta.Instead of using a conventional tail section with both vertical and horizontal control surfaces, the Manta aimed to leverage thrust vector control, or directing the flow of the engine’s thrust to give the aircraft the acrobatic capabilities it would need in a high-end dogfight. Today, more than two decades later, that same concept appears to be found consistently across nearly all official renderings of the Air Force’s next air superiority fighter being developed under the NGAD, or Next Generation Air Dominance, program, begging the question… could elements of the X-44 Manta have found their way America’s next top-of-the-line fighter?
