At the end of the seventies, the retirement of the Venom and the increased use of the Hunter aircraft for air-to-ground attack caused a gap in the field of area air-defence which was to be closed with the Northrop F-5E Tiger II.

In 1976, after thorough evaluation, the parliament decided on the procurement of 72 Tiger fighter aircraft, 66 of the type F-5E (single seater) and 6 of the type F-5F (double seater). The parts and assemblies were manufactured in the USA, but the Swiss Federal Aircraft Factory, Emmen, carried out the final assembly.
