The Saab 105, designated SK 60 by the Swedish Air Force, began as a private venture by Saab before the Air Force ordered 150 examples in 1964. It entered service in 1967, replacing the J 28 Vampire, and went on to serve as Sweden's primary jet trainer for decades — the last examples weren't retired until June 2024. The type came in several variants, including the side-by-side two-seat SK 60A trainer, the SK 60B attack version, and the reconnaissance SK 60C with an extended camera nose.

This aircraft, individual number 60145, is an SK 60E. It was among the first aircraft donated to F15 Flygmuseum when it opened in 1999 — reportedly a fully airworthy example at the time it was handed over.
