The Saab 37 Viggen (Swedish for Thunderbolt) is a Swedish single-seat, single-engine, short-medium-range combat aircraft. It was used as a fighter, for ground attack, and reconnaissance. It was designed with a radical canard and delta wing configuration. The Viggen entered service in 1971. It was the first canard (the little wings at the front) design produced in quantity and was also one of the most advanced fighter jets produced in Europe until the arrival of the Tornado.
