Production MIG-29K differ from prototypes by features such as a multi-function radar and several new cockpit displays; the adoption of HOTAS (hands-on-throttle-and-stick) controls; the integration of RVV-AE air-to-air missiles, along with missiles for anti-ship and anti-radar operations; and several ground/strike precision-guided weapons.
The MiG-29K was not ordered into production and only two prototypes were originally built because the Russian Navy preferred the Su-27K in the early 1990s. The Mikoyan Design Bureau did not stop its work on the MiG-29K aircraft despite the lack of financing since 1992. The program got a boost in the late 1990s to meet an Indian requirement for a ship-borne fighter following the purchase of a former Soviet aircraft carrier. It was first received by the Indian Navy in 2009.
