The Northrop F-5 was designed by Edgar Schmued, who had previously been at North American, and was responsible for the P-51 and F-86. The idea for the F-5 was to produce a lighter, less expensive and more maneuverable fighter, going against the 1960s trend of bigger, heavier fighters. The F-5 has been successful, used by more than 20 foreign operators, as well as the US Navy, as an F-5N aggressor aircraft.
