Following the resounding success of the F-5A Freedom Fighter, the USAF issued a request in 1970 for a new light fighter aircraft that could both be exported to America's allies (Under the Mutual Assistance Plan, or MAP) or put on the international market. Northrop decided to repeat the feat of the F-5A a second time, and offered up a brand-new variant, the F-5E Tiger II. Named to honour the well-known Skoshi Tiger Unit that was formed solely to test out the F-5A during the Vietnam War, the F-5E Tiger II, just like its predecessor, instantly became an enormous hit on the export market. For a price of about two million dollars US (Today), a country could equip its air force with a light, modern single-seat fighter. The tactical RF-5E Tigereye and the F-5F Tiger II also soon hit the market, seeing success with a number of Asian, Middle-Eastern and European countries.
