US 6th‑gen fighter jet engine tech signal shift in air dominance strategy

The upcoming US sixth-generation fighter jet, designated the F-47 and expected to fly in 2028, is being developed under the Next Generation Air Dominance (NGAD) program to replace the F-22 Raptor. Boeing and the US Air Force have kept most specifications classified, but the F-47 is anticipated to be a long-range air superiority fighter capable of speeds around Mach 2 and a range exceeding 1,000 nautical miles. A recent Pratt & Whitney video, while primarily showcasing the XA-103 adaptive engine’s digital twin development, briefly reveals a possible F-47 render featuring a modified delta wing, tailless design, and high cockpit, though this image may be intentionally misleading. The XA-103 engine, developed under the Next Generation Adaptive Propulsion (NGAP) program, is expected to enhance the F-47’s performance by increasing its range by 25% and thrust by 10% compared to the F-35 engine. It incorporates advanced thermal management
