The Saab 35 Draken, a groundbreaking Cold War era fighter, was Sweden’s response to the escalating threats from the USSR. Introduced as the first Western European airframe with supersonic capabilities, the Draken also pioneered the double delta wing configuration and was the first to perform the Cobra maneuver. Designed to meet the unique demands of Sweden’s Bas-60 air base system, it could operate from improvised runways and was optimized for high-speed interceptions, reaching speeds up to Mach 2.0.
