Swedish Air Force Saab J-37 Viggen (Part 1). The Viggen was designed as a Cold War-era multi-role fighter, and proved itself throughout its career to be versatile in air superiority, attack/strike, antiship, and recce roles. First flying in 1967, with 329 aircraft built, the Viggen served the Flygvapnet (Swedish Air Force) for 34 years. I present an 8-LOD AI traffic model to bring another Cold War icon to the flightsim world. This first of two package represents the AJ-37 (strike), JA-37 (air superiority), SH-37 (maritime recce/antiship), SF-37 (recce), and SK-37 (two-seater) in the service of the Swedish Air Force, with 20 models and 82 repaints.
