The story of the “Hornet” is one of evolution and consolidation within the American aviation industry. The original version of the aircraft, the A/B models followed by the C/D variants, was developed by McDonnell Douglas in the 1970s, based on Northrop’s YF-17 Cobra prototype, which had lost the USAF competition. The U.S. Navy saw potential in the design, as it needed an aircraft to replace the aging F-4 Phantom II and the A-7 Corsair II attack aircraft.
