AL-21F-3 is a third-generation single-circuit, single-shaft turbojet engine with an afterburner developed under the supervision of OKB-165 General Designer A. M. Lyulka. It is a further development of the basic AL-21F engine and differs from it in increased thrust and improved characteristics. It was installed on the Su-24 frontline bomber, the Su-17 and MiG-23B fighter-bombers, as well as on the first T-10 prototypes. After completion of their use in aviation, after modification and modernization, the Al-21F3 engines are used as drives for ground-based power and gas pumping units manufactured by the Federal State Unitary Enterprise “Scientific and Production Center for Gas Turbine Engineering “Salut”

-AL-21F-3 (article 89) – forced. It was distinguished by increased air consumption, increased pressure and temperature of the gas in front of the turbine.
