India is to buy around 350 T-90S main battle tanks from Russia under a deal to be inked in autumn this year, according to a top military official in Moscow.

"The contract for their delivery will be signed in autumn this year, although it was initially to be signed this month," Chief of the Russian Defence Ministry's mechanised armoured department, Colonel-General Vladislav Polonsky, was quoted as saying by ITAR-TASS.

According to General Polonsky, like in the case of previously executed contract for the sale of 300 T-90S, the new deal would also be completed within 3-4 years.

"As a result of the tank deals, India will have two divisions fully equipped with latest Russian T-90 tanks," Gen Polonsky said.
