The SAAB JAS 39 Gripen

Since World War II, the Swedish SAAB aircraft firm has maintained a tradition of building cutting-edge fighter aircraft for the defense of Sweden. The latest of this series of aircraft, the SAAB "JAS 39 Gripen (Griffin)", is now in operational service. The Gripen is a state-of-the-art multirole combat aircraft, arguably the first "fourth-generation" jet fighter to reach service. It maintains the tradition of excellence in Swedish fighter design, but departs from tradition in proving a competitive item for export sales. This document provides a history and description of the Gripen.
