The Saab 37 Viggen featured an extremely advanced aerodynamic configuration for its time, combining a main delta wing with delta-shaped canard foreplanes. As told by Jan Jørgensen, Anders Nylén and Peter Liander in their book Saab 37 Viggen – The ultimate portfolio, this unconventional design enabled the Viggen to meet the Swedish Air Force requirement for speed of Mach 2+ at high altitude and ability to operate from 500 m runways.

To keep the landing distance short Saab developed a thrust-reverser integrated with the rear fuselage, still the only one if its kind on single-engined aircraft. The Viggen was powered by the Volvo Flygmotor RM8A/B afterburning turbofan.

The SK 37 was the trainer variant of the Viggen. It was designed simply by adding an extra cockpit behind the cockpit of the single-seat Viggen, given the Skol-Viggen a very distinctive configuration with two separate canopies.

During 1998-2000 the Swedish Air Force carried out a comprehensive modification program to convert 10 SK 37s into SK 37E Electronic Warfare aggressors, taking over the role of the J 32E Lansen which had been retired a few years earlier. The SK 37E variant became referred to as jammer-Viggen.
