The Tumansky RD-9 (initially designated Mikulin AM-5) was an early Soviet turbojet engine, not based on pre-existing German or British designs. The AM-5 was available in 1952 and completed testing in 1953; it produced 5,732 lbf (25.50 kN) thrust without afterburner. AM-5 engine is notable for making possible the first Soviet supersonic interceptor MiG-19 and the first all-weather area interceptor Yak-25. When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9. The engine was later built under license in China as the WP-6.
