Three discarded Russian aircraft carriers are now in China. The light carriers Kiev and Minsk are now centerpieces in military theme parks, one in south China and another north China. But the Varyag, a large attack carrier, officially undergoing conversion to a floating casino, is under heavy guard. This is leading to persistent rumors that the Varyag is being converted to military use, or at least being closely studied by naval architects and shipbuilders for information on how to build an aircraft carrier.
