China's Newest Nuclear Submarine Sinks at Shipyard, US Officials Claim

The Zhou-class submarine's sinking earlier this year raises questions about China's military transparency and defense industry standards.

The first of China's Zhou-class nuclear-powered attack submarines sank between May and June at the Wuchang shipyard near Wuhan.
Satellite images showed cranes and salvage equipment at the site, indicating efforts to recover the submerged vessel.
US defense officials suggest the incident highlights issues with the People's Liberation Army Navy's training standards and equipment quality.
The Chinese government has not confirmed the sinking, with officials stating they have no information on the matter.
The incident is seen as a setback for China's naval ambitions, which include expanding its fleet to rival US maritime power.
