WASHINGTON—China’s newest nuclear-powered attack submarine sank in the spring, a major setback for one of the country’s priority weapons programs, U.S. officials said.

The episode, which Chinese authorities scrambled to cover up and hasn’t previously been disclosed, occurred at a shipyard near Wuhan in late May or early June.

It comes as China has been pushing to expand its navy, including its fleet of nuclear-powered submarines.

The Pentagon has cast China as its principal long-term “pacing challenge,” and U.S. officials say that Beijing has been using political and military pressure to try to coerce Taiwan, a separately governed island that Beijing claims as part of its territory.

China says its goal in building a world-class military is to deter aggression and safeguard its overseas interests. A spokesman for the Chinese embassy didn’t immediately respond to a request for comment.

The U.S. doesn’t know if the sub was carrying nuclear fuel at the time it sank, but experts outside the U.S. government said that was likely.

Undersea technology has long been an area of U.S. advantage, but China has been pushing hard to narrow the gap.

China has been moving to diversify the production of nuclear-powered submarines. Production has been centered in the northeastern city of Huludao, but China is now moving to manufacture nuclear-powered attack submarines at the Wuchang Shipyard near Wuhan.

Beijing had 48 diesel-powered attack subs and six nuclear-powered attack subs at the end of 2022, according to a Pentagon report issued last year on China’s military power,

That report said that China’s aim in developing new attack submarines, surface ships and naval aircraft is to counter efforts by the U.S. and its partners to come to Taiwan’s aid during a conflict and to achieve “maritime superiority” within the first island chain, a string of territory from the Japanese archipelago through Taiwan and the Philippines to the South China Sea.

The Zhou-class vessel that sank is the first of a new class of Chinese nuclear-powered subs and features a distinctive X-shaped stern, which is designed to make the vessel more maneuverable.

The sub was built by China State Shipbuilding Corp., a state-owned company, and was observed alongside a pier on the Yangtze River in late May when it was undergoing its final equipping before going to sea.

After the sinking, large floating cranes arrived in early June to salvage the sub from the river bed, according to satellite photos of the site.

“The sinking of a new nuclear sub that was produced at a new yard will slow China’s plans to grow its nuclear submarine fleet,” said Brent Sadler, a senior research fellow at the Heritage Foundation, a Washington think tank, and a retired U.S. Navy nuclear submarine officer. “This is significant.”

Neither the People’s Liberation Army, as the Chinese military is known, nor local authorities, have acknowledged the episode.

“It’s not surprising that the PLA Navy would try to conceal the fact that their new first-in-class nuclear-powered attack submarine sank pierside,” said a senior U.S. defense official. “In addition to the obvious questions about training standards and equipment quality, the incident raises deeper questions about the PLA’s internal accountability and oversight of China’s defense industry, which has long been plagued by corruption.”

The first public indication that something was amiss at the shipyard near Wuhan came in the summer when Thomas Shugart, a former U.S. submarine officer and an adjunct senior fellow at the Center for a New American Security, wrote a series of social-media posts noting the unusual activity of the floating cranes, which was captured by commercial satellite imagery.

Shugart surmised that there might have been an incident that involved a new type of submarine, but he didn’t know at the time that it was nuclear-powered.

“Can you imagine a U.S. nuclear submarine sinking in San Diego and the government hushes it up and doesn’t tell anybody about it? I mean, Holy Cow!” Shugart said in an interview this week with The Wall Street Journal.

While the submarine was salvaged, it will likely take many months before it can be put to sea.

“The whole boat would be full of water,” Shugart said. “You’d have to clean out all the electronics. The electric motors may need to be replaced. It would be a lot of work.”

American officials haven’t detected any indication that Chinese officials have sampled the water or nearby environment for radiation. It is possible Chinese personnel were killed or injured when the sub sank, but U.S. officials say they don’t know if there were casualties.

Shugart said that the risk of a nuclear leak was likely to be low as the sub hadn’t ventured out to sea and its reactors were probably not operating at a high power level.

The U.S. has suffered similar setbacks, which proved costly. In 1969, the nuclear-powered USS Guitarro was moored at a shipyard in California when it sank following a series of mistakes by construction workers. It wasn’t officially commissioned until 32 months after its sinking.

The Chinks have failed to develop a nuclear submarine force because its the one tech we keep extremely close hold

Our problem is that we no longer have the industrial base to build and repair them fast enough

Also skimmed the part where some faggot said can u imagine a sub sinking in San Diego and the US govt lying abt it? LJL, all the US govt does is furking lie, they are lying abt everything in Ukraine right now, and all the shit abt the Houthis. A US Navy tanker just got PWN'd by 180 HOUTHIS and they are not disclosing the truth
