F-20 "Tiger shark" Jet fighter

Due to export restrictions by the Department of Defence preventing sales of advanced avionics and aircraft to export customers, many allies who were flying the now out-dated F-5 could not purchase the latest F-16 aircraft to meet the threat of the latest MiG-29s and Su-27s that Soviet allies were receiving. As a result, Northrop Grumman initiated the FX program, to design and build a new 4th light export generation fighter on the basis of the cancelled F-5F Super Tiger. The primary requirements for this new fighter were cheap interoperability with existing F-5 fleets, BVR capability, and modular compatibility with almost every kind of ordnance the US offered for export at the time.
