It also contains systems that reduce its infrared and optical visibility.

In 2005, Russia and India signed a $250 million deal aimed at modernizing engines for the MiG-29 fighters of the Indian Air Force. Under the terms of the deal, HAL is to produce 120 RD-33 series-3 jet engines at its Koraput plant as part of an overall upgrade of MiG-29 fighters.

This contract is expected to help HAL master not just the assembly of the RD-33 jet engines but also use the experience in the assembly of next generation jet engines.

Russia has said that it will deliver the first two MiG-35 aircraft to India in August for flight trials as part of the selection process for the MMRCA tender. Later on in the year it will conduct live firing tests for an Indian air force delegation at a testing ground in Russia.

Moscow has stressed that it is ready to transfer all key technology to India's Hindustan Aeronautics Ltd if the MiG-35 should win the tender.
