The Saab 210, nicknamed the \'Lill Draken\', was a scale test bed used in the development of the supersonic J35 Draken. The Saab 210 \'Lill Draken\' was primarily used to test and develop the highly swept wing design and better understand the flight characteristics of such a design. The aircraft was powered by a single Armstrong Siddeley Adder AS.A.1 turbojet engine. During its lifetime the Saab 210 \'Lill Draken\' was modified to improve flight dynamics and better represent the final design of the full size aircraft.
