Here’s a little update on this fighter design we showed you yesterday. It is indeed Boeing’s concept for a sixth-gen “air dominance” fighter for the U.S. Navy and Air Force, Daryl Davis, chief of Boeing’s Phantom Works division told me today. The plane, which is still just a concept, would have long-ranger range and fly at “higher mach numbers” (faster) than jets like the F-35 Joint Strike Fighter and be able to supercruise, according to Davis.
