The Saab 37 Viggen is a single-seat, single-engine multirole combat aircraft designed and produced by the Swedish aircraft manufacturer Saab. It was the first canard-equipped aircraft to be produced in quantity and the first to carry an airborne digital central computer with integrated circuits for its avionics, arguably making it the most modern/advanced combat aircraft in Europe at the time of introduction. The digital central computer was the first of its kind in the world, automating and taking over tasks previously requiring a navigator/copilot, facilitating handling in tactical situations where, among other things, high speeds and short decision times determined whether attacks would be successful or not, a system not surpassed until the introduction of the Panavia Tornado into operational service in 1981.

Saab AB, with subsidiaries collectively known as the Saab Group, is a Swedish aerospace and defense company primarily operating from Sweden. The company is headquartered in Stockholm, but its development and manufacturing operations are undertaken in Linköping.
