The XA100 is an “adaptive cycle” engine, designed for maximum efficiency across subsonic, transonic, and supersonic flight speeds. Being engineered to seamlessly, and automatically, go from high-thrust events — think takeoff and advanced aerial combat maneuvers — to high-efficiency mode makes the XA100 a true super jet. Additionally, the XA100 exhibits high fuel efficiency on long-haul flights, which, of course, is not something that fighter jets are traditionally known for. But Tweedie says that’s about to change.
