The Saab JAS 39 Gripen (English: Griffin) is a lightweight single-engine multirole fighter 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 technology. It is powered by the Volvo-Flygmotor RM12 engine, a derivative of the General Electric F404, and has a top speed of Mach 2.

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. Comparatively small relative to similar fighters, the Gripen has eight hardpoints that allow it to carry various armaments and equipment. It is also fitted with a single 27 mm Mauser BK-27 cannon.

Beset by early problems with its avionics during flight testing, during which a prototype was lost, the aircraft entered service in 1997. Saab has since cooperated with other aerospace companies in marketing the aircraft internationally, and has achieved moderate success in Central Europe, South Africa and Southeast Asia. More than 240 Gripens have been delivered or ordered as of 2012.
