The F-5 is a legendary fighter plane designed and built by the American company Northrop, which in the 1960s was the only manufacturer of combat aircraft to offer a light and cheap fighter. The F-5 was produced in two versions; single-seat, fighter designated F-5A and two-seat, training and combat F-5B. The F-5 was much smaller than modern fighters weighed about a third of the weight of the popular F-4 Phantom.
