Hindustan Aeronautics expects the Indian air force to order an additional 42 locally produced Sukhoi Su-30MKIs.

The possible order would come on top of the 180 Su-30MKIs HAL is already producing for the air force, says company chairman Ashok Nayak.

About 105 aircraft from the 180-strong order have been delivered so far, Nayak says. In addition, in mid-2010, India ordered 40 Su-30MKIs as flyaways from Russia's Sukhoi.
