The Tumansky RD-9 (initially designated Mikulin AM-5) was an early
Sovietturbojet engine, not based on pre-existing German or British designs. The AM-5, developed by scaling down the
AM-3,[1] was available in
1952 and completed testing in
1953; it produced 25.5 kN (5,700 lbf) thrust without
afterburner. The AM-5 engine is notable for making possible the first mass-produced supersonic interceptors such as the
MiG-19, and the first Soviet all-weather area interceptor, the
Yak-25.[2] When
Sergei Tumansky replaced
Alexander Mikulin as the
OKB-24's chief designer in 1956, the engine was renamed RD-9.[citation needed] The engine was later built under license in China as the WP-6.
