Saab 105

The Saab 105 is a Swedish high-wing twinjet trainer aircraft that Saab AB developed as a private venture in the early 1960s, starting in 1959. Saab meant it for many military and civil roles, from jet trainer to reconnaissance, ground attack and a limited interceptor, and even proposed a four-to-five seat business jet cabin, though no business customers appeared. The Swedish Air Force sponsored a prototype, which first flew on 29 June 1963, and bought 150 aircraft, designated Sk 60, that entered service in 1967 to replace the de Havilland Vampire. Austria bought 40 as the Saab 105 O, and Swedish and Austrian display teams flew it. It was typically powered by two Turbomeca Aubisque turbofans, later replaced in the Swedish fleet by Williams FJ44 engines. Sweden officially retired the type on 18 June 2024.
