U.S. Air Force's Sixth-Gen Fighter Jet May Use Interim Engine
The U.S. Air Force's upcoming F-47 fighter jet, part of the Next Generation Air Dominance (NGAD) program, may initially fly with a less powerful interim engine. The NGAD program aims to integrate advanced technologies such as stealth, AI, and long-range capabilities into the F-47. However, the development of the aircraft's most advanced engine, under the Next Generation Adaptive Propulsion (NGAP) effort, may not align with the jet's production schedule. The NGAP engines are designed to adapt airflow for different flight conditions, enhancing thrust and fuel efficiency. If these engines are not ready, the Air Force might use an existing engine for the first production aircraft, allowing the F-47 to enter service sooner while the NGAP engines are further developed.
