The addition to the hangar, which is situated near Bosten Lake in China’s Xinjiang Autonomous Region, can be seen in new satellite imagery that The War Zone obtained from Planet Labs. Construction of the original 1,150-foot-long and 450-foot-wide hangar, which is also extremely tall, started in 2013 and looks to have wrapped up in 2015. To give a sense of just how big the structure is, length and width-wise at least, a U.S. Navy Nimitz class supercarrier would have already fit inside the hangar with 100 feet to spare on either side before the extension was added on.
