In the history books of flight, there are some planes that never took to the skies and yet cast a permanent shadow over future models. Of these, one design has gone on to influence the U.S. direction of next-generation fighters more than any other: the X-44 Manta, a project that may have never lifted off but produced innovations to mark the future direction of stealth fighters.
The X-44 Manta, created in 1999 by Lockheed Martin and then with NASA in partnership, is a showcase of cutting-edge aeronautics with its design as a Multi-Axis No Tail Aircraft. The unique delta-shaped configuration, lacking a traditional tail section, held out the promise of greater stealth and maneuverability via thrust vector control. The X-44 Manta never made it past a design concept, but its short life influenced later stealth designs that may be taken up by the U.S. NGAD, emphasizes the potential of an aircraft that might have eclipsed its stealthier replacement, the F-22.
Lockheed’s X-44 was estimated to wow with its stretched-delta configuration and coveted spec sheet, including achieving speeds of 1,500 miles per hour and a 49,000-foot ceiling. The Manta’s internal weapons bays, which were streamlined and efficient, were to include an incredible load of Sidewinders, AMRAAMs, precision-guided bombs, and a 20mm internal cannon. These are not only specs that were to make it a formidable fighting machine but also an aircraft that could “carry a whole lot more hate,” to borrow the quote of Alex Hollings on Sandboxx.
Jump ahead to today, and the U.S. Air Force has allegedly built a prototype and test flown the Next Generation Air Dominance (NGAD) fighter, the U.S. Navy version being the F/A-XX on its own development path. The programs are designed to achieve the 6th-generation stealth fighter.
Pratt & Whitney, a leader in aviation propulsion, has conducted the critical design review of an advanced engine to power the NGAD on behalf of the U.S. Air Force. Next-generation adaptive propulsion is such a commitment toward ensuring future air superiority with technology that combines quick thrust with the optimization of efficiency. “Continued government funding for sixth-generation propulsion development must remain a high priority,” said Jill Albertelli, president of Pratt & Whitney’s Military Engines business. The NGAD’s foundation will be a system-of-systems design with open standards to integrate seamlessly with a fleet of crewed and uncrewed assets.
