Brief History

Brief History
Engine Division- Koraput was set up in April 1964 to manufacture R11-F2/F2S turbojet engine for MiG-21FL aircraft. Subsequently    the Division took up manufacturing of R25 series engines of MiG-21BIS aircraft & R29B engines for MiG27M aircraft. Simultaneously facilities for Overhaul of R11, R25, R29B and RD-33 were started. From 2007-08 onwards Division started manufacturing of RD-33 Ser.3 engines for MiG-29 aircraft.

To support manufacturing of aeroengines from raw material stage, FORGE AND FOUNDRY UNIT was established in the Year 1967.

Over last five decades Division has manufactured more than 1337 engines and overhauled more than 7700 Aero Engines.
