ZHUKOVSKY /Moscow region/, August 15./ITAR-TASS/. A Russian producer of anti-submarine planes said it will effect consecutive repairs of five Il-38SD aircraft which are in service with India, Director General of the Il company Yuri Yudin told ITAR-TASS on Friday.

"We're overhauling the second Indian aircraft, and the next plane is to arrive in about four months," Yudin said, adding that the overhaul would include a minor upgrade.

He said India was no longer interested in these planes and that their further sales were unlikely.

India purchased five Il-38s in 1975 - 1983; in the 2000s they were upgraded to the Sea Dragon version, featuring 14 hours of loiter time at a speed of 400 km/h. The maximum speed of these planes is 610 km/h, and the maximum range is 6,500 kilometers.

In 2009, India signed a $2.1-billion contract to purchase eight US-made P-8I Poseidon anti-submarine aircraft. The first plane was supplied in 2013. India has an option to buy four more planes for $1 billion.
