In 1947, Soviet Union bought from Great Britain a batch of Rolls Royce Derwent and Rolls Royce Nene engines along with specification sheets. This purchase enabled the Soviets to catch up with world's leaders in aviation technology. For the production of the engines the Russians used already their own technologies. The technical and operating parameters of the RD-500 were comparable with its western equivalents.
The Rolls Royce Derwent was produced as the RD-500. It powered Yakovlev Yak-23 and Lavochkin La-15 aircraft.
