KABUL, November 15 (SPA) - The U.S. military will give Afghanistan 20 refurbished transport planes over the next two years, U.S. and Afghan officials said on Sunday, doubling the size of its depleted air force. Two of the C-27A medium-sized military transport aircraft, manufactured by Italy"s Alenia Aeronautica, have already been delivered, Afghan Air Corps Chief of Staff General Abdul Wahab Wardak told Reuters. U.S. Army General Stanley McChrystal, U.S. and NATO commander in Afghanistan, said the remainder of the twin-engine, turbo-prop planes would be delivered by 2011. "With the delivery of the C-27s, the brave and skilled pilots of the air corps gain the ability to conduct many of the same airlift missions done by coalition forces in defense of their country," McChrystal said at a military ceremony in Kabul. "With the arrival of new aircraft our air force will have 40 aircraft including nine helicopters," Wardak said. "By 2016, the Afghanistan Air Corps will have 150 aircraft and around 8,000 personnel," Wardak said. --SPA 13:29 LOCAL TIME 10:29 GMT www.spa.gov.sa/719165
