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, developed by scaling down the AM-3,{{cite book |last1=Belyakov |first1=R.A. |last2=Marmain |first2=J. |title=MiG 1939-1989 |date=1991 |publisher=Editions Larivière |location=Paris |isbn=2-907051-00-8 |page=137}} was available in 1952 and completed testing in 1953; it produced {{convert|25.5|kN|abbr=on}} 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.{{cite book|page=[https://archive.org/details/bub_gb_HoxycYhoKZkC/page/n245 245]|url=https://archive.org/details/bub_gb_HoxycYhoKZkC|title=History of Strategic and Ballistic Missile Defense: Volume II|publisher=DIANE Publishing|isbn=9781437921311|last1=Leonard|first1=Barry|date=January 2011}} When Sergei Tumansky replaced Alexander Mikulin as the OKB-24's chief designer in 1956, the engine was renamed RD-9.{{citation needed|date=September 2013}} The engine was later built under license in China as the WP-6.
