The Saab JAS 39 Gripen (English: "griffin" is a light single-engine multirole fighter aircraft manufactured by the Swedish aerospace company Saab. It was designed to replace the Saab 35 Draken and 37 Viggen in the Swedish Air Force (Flygvapnet). The Gripen has a delta wing and canard configuration with relaxed stability design and fly-by-wire flight controls. It is powered by the Volvo RM12, and has a top speed of Mach 2. Later aircraft are modified for NATO interoperability standards and to undertake air to air refuelling.In 1979, the Swedish government began development studies for an aircraft capable of fighter, attack and reconnaissance missions to replace the Saab 35 Draken and 37 Viggen. A new design from Saab was selected and developed as the JAS 39, first flying in 1988. Following two crashes during flight development and subsequent alterations to the aircraft's flight control software, the Gripen entered service with the Swedish Air Force in 1997. Upgraded variants, featuring more advanced avionics and adaptations for longer mission times, began entering service in 2003.
To market the aircraft internationally, Saab formed partnerships and collaborative efforts with multiple overseas aerospace companies. One example of such efforts was Gripen International, a joint partnership between Saab and BAE Systems formed in 2001. Gripen International was responsible for marketing the aircraft, and was heavily involved in the successful export of the type to South Africa; the organization was later dissolved amidst allegations of bribery being employed to secure foreign interest and sales. On the export market, the Gripen has achieved moderate success in sales to nations in Central Europe, South Africa and Southeast Asia; bribery has been suspected in some of these procurements, but authorities closed the investigation in 2009.
A further version, designated Gripen JAS 39E/F, is under development as of 2014; it has been referred to as Gripen NG or Super-JAS. The changes include the adoption of a new powerplant, the General Electric F414G, an active electronically scanned array radar, and significantly increased internal fuel capacity. Saab has proposed other derivatives, including a navalised Sea Gripen for carrier operations and an optionally manned aircraft for unmanned operations. Sweden and Brazil have ordered the Gripen E/F and Switzerland initially selected it for procurement. As of 2013, more than 247 Gripens have been built.
