India's sole current aircraft carrier, the 29,000 ton INS Viraat, is running out of Harrier aircraft. Two years ago, Viraat emerged from 18 months in a shipyard getting maintenance and upgrades. With its engine and hull refurbished, and its electronics upgraded, India has announced that Viraat will serve for another decade. But back in 2009, one Harrier had just crashed, and now only ten of the original 30 Harriers are operational. Since Britain recently retired the last of its Harriers, there's always the possibility of India getting some of those before they are scrapped
