Afghanistan will receive 21 Mi-17 Hip military transport helicopters from Russia as part of an estimated $300m contract.
Russian envoy to Nato Dmitry Rogozin told RIA Novosti that Nato would decide on the exact delivery date some time in July.
The Mi-17 medium twin-turbine transport helicopter used by the Afghan Air Force can also act as a gunship for troop and cargo transport, rescue and evacuation missions in the fight against Taliban militants.
The air force with 25 existing Mi-17 helicopters, has plans to increase the number of such helicopters to 56 by 2012.
