The Sk-60 is a twin engined trainer aircraft with attack/reconnaissance and liaison capability (versions A-E). 150 aircrafts were delivered to the Royal Swedish Air Force in 1966 - 1969. The Sk-60 will be operational at least to 2015. A service life extension program started in 1987. Installation of new models turbofan engines (Williams - Rolls FJ44) was decided in November 1993. 115 aircrafts will be modified in 1994 - 1998.
The new engines will give improved performance, better environmental characteristics and lower service and maintenance costs.
