The F-5 started life as a privately-funded light fighter program by Northrop in the 1950s. The first generation F-5A Freedom Fighter entered service in the 1960s. Over 800 were produced through 1972 for U.S. allies during the Cold War. The USAF had no need for a light fighter, but it did need a trainer and procured about 1,200 of a derivative airframe for this purpose, the T-38 Talon.

The improved second-generation F-5E Tiger II was also primarily used by American Cold War allies and, in limited quantities, served in US military aviation as a training and aggressor aircraft; Tiger II production amounted to 1,400 of all versions, with production ending in 1987. Many F-5s continuing in service into the 1990s and 2000s have undergone a wide variety of upgrade programs to keep pace with the changing combat environment. The F-5 was also developed into a dedicated reconnaissance version, the RF-5 Tigereye.

The F-5N/F remain in service with the United States Navy as an adversary trainer.
