ummmm...Top Gun is Navy, not Air Force...
Are Air Force pilots now attending Navy "Top Gun" school? Anyone?
TOP GUN is open to the best pilots of all the services, including NATO pilots.
US Air Force
Since 1949, the United States Air Force has operated a similar training program at the United States Air Force Weapons School (formerly called the “United States Air Force Fighter Weapons School” and the “Aircraft Gunnery School”), and conducts large-scale tactical training exercises (see Red Flag) at Nellis Air Force Base, Nevada. Whereas the Navy’s Top Gun program is 9 weeks long, the US Air Force Weapons School program is five and a half months long. The program includes nearly every type of aircraft in the Air Force inventory as well as courses focused on intelligence, command and control, space and cyber operations.
