2007 Northrop F-5A/B Freedom Fighter and the F-5E/F Tiger II are part of a supersonic light fighter family, initially designed in the late 1950s by Northrop Corporation. Being smaller and simpler than contemporaries such as the McDonnell Douglas F-4 Phantom II, the F-5 cost less to both procure and operate, making it a popular export aircraft. The F-5 started life as a privately funded light fighter program by Northrop in the 1950s. The design team wrapped a small, highly aerodynamic fighter around two compact and high-thrust General Electric J85 engines, focusing on performance and low cost of maintenance. Though primarily designed for the day air superiority role, the aircraft is also a capable ground-attack platform. The F-5A entered service in the early 1960s. During the Cold War, over 800 were produced through 1972 for U.S. allies. Though the USAF had no acknowledged need for a light fighter, it did procure roughly 1,200 Northrop T-38 Talon trainer aircraft, which were directly based on the F-5A.

The Northrop F-5 is a family of supersonic light fighter aircraft that was developed by Northrop Corporation in the late 1950s. The F-5 has two main variants: the F-5A and F-5B Freedom Fighter, which were designed as low-cost export fighters for US allies, and the F-5E and F-5F Tiger II, which were upgraded versions with more powerful engines, improved avionics, and greater fuel capacity. The F-5 is a small, agile, and reliable aircraft that can perform both air-to-air and air-to-ground missions. The F-5 has been used by over 30 countries and is still in service with some of them. The F-5 also served as the basis for several other aircraft, such as the T-38 Talon trainer, the F-20 Tigershark fighter, and the Iranian HESA Kowsar fighter.
