Swedish Air Force saab 105 solo display
Saab 105 (Sk60A)
The Saab 105 is a Swedish high-wing, twinjet trainer aircraft developed in the early 1960s as a private venture by Saab AB. The Swedish Air Force, which had opted to procure the type for various roles, issued the aircraft with the designation Sk 60. The Sk 60 entered service in 1967, replacing the ageing De Havilland Vampire fleet. There were talks of buying Folland Gnat but it became a source of inspiration.
The Swedish Air Force bought a total of 150 aircraft and another 40 were exported to Austria, designated Saab 105Ö. The Saab 105 is also the aircraft used by Swedish Air Force display team Team 60 and was formerly used by two display teams of the Austrian Air Force, "Karo As" and "Silver Birds".
The Saab 105 was developed to function as a small and inexpensive multirole aircraft, which has been most typically used in a training capacity. It is an all-metal twin-jet aircraft with a pressurized cabin. It features a T-tail configuration, modestly swept wings, and a pair of engines mounted on either side of the fuselage just underneath the wing.
The 105 can be outfitted with various armaments and equipment to perform a wide range of duties, most of which would be installed upon the aircraft's six underwing hardpoints. In a ground-attack/close air support capabilities, the 105 can employ a combination of 135 mm, 127 mm, and 75 mm unguided rockets, air-to-ground missiles and assorted bombs, including napalm bombs; either a pair of 30 mm cannon or 7.62 mm guns may be installed using a series of gun pods. In the air defence role, AIM-9 Sidewinder air-to-air missiles can be employed in addition to cannons. Additionally, for the purpose of carrying a maximum of two passengers, smaller ejector seats can be installed for the pilot and co-pilot while a small bench directly behind them can be used by the passengers. Generic and more specialized surveillance/reconnaissance missions can also be performed by the Saab 105, having the option of being fitted with radiation detection equipment for atmospheric sampling. With suitable equipment, the 105 could be readily converted between trainer and light attack roles.
As-built, the Saab 105 was typically powered by a pair of Turbomeca Aubisque low-bypass turbofan engines, licence-manufactured by Volvo Flygmotor as the RM9. The Aubisque engine reportedly provided favourable engine-out characteristics, allowing the aircraft to proceed to successfully takeoff in the event of a single-engine failing at the critical point. This has not been the sole powerplant for the type, as a number of 105 aircraft have been powered by the General Electric J85 engine instead. Swedish Air Force aircraft have been remanufactured during the 1990s to use the newer Williams International FJ44, which has been designated as the RM15.
