In 1946, the British government allowed Rolls-Royce to export the Nene turbojet engine to the Soviet Union. The Klimov construction bureau quickly copied the engine then began improving it.
The resulting RD-45 (later VK-1) began production in 1947. Over 39,000 were produced. A further 8,500 were built in China by Shen Yang under license.
