Svenska Flygmotor A.B. of Trollhättan, Sweden was founded as Nohab Flygmotor in 1930 and changed the name to Svenska in 1941. After WWII, Svenska was owned jointly by Volvo and Bofors. The firm had extensive experience building piston engines under license from the German Daimler Benz, the UK Bristol, and the US Pratt & Whitney firms. In 1947, the firm was beginning to produce jet engines under license from DeHavilland (UK) and have continued to develop and build turbine engines.
