HISTORY: The light attack/advanced jet trainer Saab 105 began life as a private venture.
Saab designed the 105 to be capable of a number of different missions as diverse as ground attack, reconnaissance, basic and advanced pilot training, liaison, target towing and even air ambulance. The first of two Saab 105 prototypes made its first flight on June 29 1963, while the following year the Royal Swedish Air Force ordered 130 production aircraft (later 150) as the Sk 60. The first production Sk 60 flew in August 1965.
The Sk 60A trainer entered service in 1966. These aircraft were delivered unarmed but were later retrofitted to carry hardpoints for weapons, allowing a secondary wartime ground attack role. The Sk 60B meanwhile is primarily tasked with weapons training and ground attack. The Sk 60C has a Fairchild KB-18 reconnaissance camera in the nose, but also retains a secondary ground attack capability. The Sk 60D and four seat Sk 60E (with the two ejection seats replaced by four fixed seats) are used for liaison and check rides.
From 1996 to 1998 Sweden's Sk 60 fleet will be progressively reengined with Williams Rolls FJ44 turbofans. The prototype conversion first flew in October 1995.
The only Saab 105 export customer was Austria, who ordered 40 Saab 1050s. The 1050 is based on the General Electric J85 turbojet powered Saab 105XT, which first flew on April 29 1967. The Saab 105XT was intended for export and apart from the more powerful engines has improved avionics, greater internal fuel capacity and a strengthened wing allowing an increased external ordnance load. For many years the 1050s, armed with AIM-9s, were tasked with air defence and were Austria's only jet fighters until the arrival of the Draken. Saab has also offered the improved 105G, and more recently a 105 development to meet the USA's JPATS trainer requirement. It was ruled out when the US stipulated tandem seating.
