Looks like a transport, when I first saw it, kind off made me think of a C130, inside what looks like a hangar under construction or already bombed out? Wasn't in the 10/24/2012 imagery but was visible on the 5/15/2013 imagery.
My best guess is the Chinese are testing or a new design of bunker/hangar or testing the damage one of their bombs does to a bunker with some sort of airplane inside...
