Saab Gripen NG

A Saab Gripen NG multirole fighter on patrol over the sea.

The Saab JAS 39 Gripen (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 Saab 37 Viggen in 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 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 27mm Mauser BK-27 cannon.

The JAS 39 first flew in 1988. After early problems with avionics were rectified, 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 and Northern Europe. More than 240 Gripens have been delivered or ordered as of 2012. 1a
