Engine Division, koraput was set up in the year 1964 to make R11F2-300 Sr III motors for fitment in MiG-21FL Aircraft under permit from past USSR. In 1976 offices were set up to produce R25 motors for fitment in MiG-21BIS airplane. Accordingly Division additionally made R29b and RD33 Engines under permit from Russia.

Since the mid 1970, updating offices were built up in the Division and Division has been upgrading Aero Engines of Various sorts i.e. R11, R25, R29 and RD33 which control MiG-21FL, MiG-21BIS, MiG-27 and MiG-29 separately.

Over most recent five decades Division has fabricated more than 1300 motors and updated more than 7000 Aero Engines of different sorts with an expect to guarantee greatest air ships flying.

The Division takes after the 'Gathering Technology' with the Engine parts being destroyed, seen and stacked to various work places for ROH exercises. Consistent audit of advance through most recent IT empowered frameworks guarantees convenient consummation of congregations and sub-gatherings of the motors. The stripped segments are liable to stringent quality checks utilizing current innovation like CMM, NDT and other non-contact estimations. Repair and renovating of exhausted parts and sub-gatherings are attempted by gifted laborers. Division is additionally fabricating the greater part of the segments in-house, which are required amid redesign.
