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.
Although the in-service aircraft receives less publicity than the air force's medium multi-role combat aircraft competition or indigenously produced Tejas light combat aircraft, the Su-30MKI is the service's backbone and has represented India in several international exercises.
HAL rolled out its first completed Su-30MKI in November 2004.
