The Jianggezhuang Naval Base (Chinese: 姜各庄) is a Chinese naval base approximately 15 miles (24 km) east of Qingdao on the Yellow Sea. The base spans a bay 1.2 miles (1.9 km) across, with the main facilities located in the eastern portion of the bay. Open source satellite imagery shows the base to be an enclosed harbour with breakwaters and a single entrance; there are six piers, a dry dock, various service facilities and an underground submarine tunnel.[1][2]
The base hosts China's Type 092-class ballistic missile submarine[3] and Type 091-class nuclear attack submarines.[4][5]
