China’s newest nuclear-powered submarine sank pierside in the spring and the Chinese Navy tried to conceal the loss, according to two US defense officials.
The attack submarine was the first of its new Zhou-class line of vessels, the official said, under construction at a shipyard near the city of Wuhan. The Zhou-class submarines have a distinctive X-shaped stern, designed to improve maneuverability underwater.
A satellite image from March 10, taken by Maxar Technologies, shows the Zhou-class sub, with its signature x-shape tail, docked at the port. Additional Maxar imagery reviewed by CNN from later in June shows that the sub did not return to the pier.
