The U.S. Air Force has secretly designed, built and flown at least one prototype of its enigmatic next-generation fighter jet, the service’s top acquisition official confirmed to Defense News on Sept. 14. The Air Force awarded a nearly $1.2 billion contract to Boeing for its first lot of eight F-15EX fighter aircraft on July 13, 2020. Almost every detail about the aircraft itself however, will remain a mystery due to the classification of the USAF’s Next Generation Air Dominance program. Source: DefenseNews
