The Jiangnan shipyard in Shanghai has undergone significant expansion in the past month, boosting China’s ability to produce large military ships, Reuters reports citing satellite images.

The shipyard is located on Changxing Island at the mouth of the Yangtze River, and has been involved in building several larger warships for the Chinese Navy, including the Type 002, Beijing’s first domestically-built aircraft carrier. Its successor, the larger Type 003, is currently under construction there as well. Images
