Sokol earlier said that the first two MiG-35 aircraft would be delivered to India in August for test flights prior to the award of the tender. In late 2009, Russia will conduct a series of flight tests with live firing for an IAF delegation at a testing ground in Russia.

The fighter is powered by RD-33 OVT thrust vectoring engines. The RD-33 OVT engines provide superior manoeuvrability and enhance the fighter's performance in close air engagements, its manufacturers say.

Moscow said if MiG-35 wins the tender, Russia is ready to transfer all key technology to India's Hindustan Aeronautics Ltd. and provide assistance for the production of the aircraft in India.
