Could this be the inspiration for the Chinese submarine accident story?

Shipuilder Newport News Shipbuilding, Va., informed the Department of Justice of faulty welds that may have been made intentionally on non-critical components on in-service Navy submarines and aircraft carriers, USNI News has learned.

HII reported to the Navy that welds on new construction and in-service submarines and Ford-class aircraft carriers were made not following welding procedure, according to a Tuesday memo from Assistant Secretary of the Navy for Research, Development and Acquisition Nickolas Guertin to Secretary of the Navy Carlos Del Toro and Chief of Naval Operations Adm. Lisa Franchetti.

Guertin told SECNAV and CNO the workers did not follow proper techniques to weld the suspect joints with an early indication that some of the welding errors were intentional. Based on the Newport News assessment of the welds, the shipyard notified the Department of Justice over the issue.

Portions of Guertin’s memo were first circulated on social media sites on Thursday.

Newport News acknowledged their internal quality assurance systems discovered production problems in a Thursday statement to USNI News

“We recently discovered through internal reporting that the quality of some welds did not meet our high-quality standards. Upon this discovery, we took immediate action to communicate with our customers and regulators, investigate, determine root cause, bound these matters and insert immediate corrective actions to prevent any recurrence of these issues,” reads the statement.
“HII’s Newport News Shipbuilding is committed to building the highest-quality aircraft carriers and submarines for the U.S. Navy. We do not tolerate any conduct that compromises our company’s values and our mission of delivering ships that safeguard our nation and its sailors.”

The Navy acknowledged the ongoing look into the scope of the welding problem in a Thursday statement to USNI News.

“The Navy is aware of the issue and a thorough evaluation is underway to determine the scope. The safety of our Sailors and our ships is of paramount importance. We are working closely with industry partners to address this situation and will provide additional information when available,” reads the statement.

The Department of Justice did not immediately respond to a request for additional information from USNI News on Thursday on the probe into the welds.

Newport News is one of two nuclear shipyards in the U.S. The yard builds the Ford-class aircraft carriers and the bow and stern sections of the Virginia-class attack submarines and the Columbia-class nuclear ballistic missile submarines in cooperation with General Dynamics Electric Boat.

Shipbuilders across the country have been wrestling with ongoing workforce problems due in part to a green labor pool that was exacerbated by the COVID-19 pandemic.

THE PENTAGON – The House Armed Services Committee is investigating substandard welding on submarines and aircraft carriers at Newport News Shipbuilding, the committee announced on Friday.

Following a Thursday report in USNI News, lawmakers are now looking into how shipbuilders at the Virginia yard had violated proper welding procedures on work that made it into current in-service submarines. The flawed work was found by quality assurance teams at Newport News Shipbuilding, which has led to a wider investigation into welding quality that’s prompted a notification to the Department of Justice, USNI News reported.

“It is deeply concerning to learn that faulty welds may have been knowingly made to U.S. Navy submarines and aircraft carriers. The House Armed Services Committee is investigating how this occurred. The safety of our sailors is our top concern, and we need to immediately understand any risks associated with the faulty work,” reads the statement from HASC chair Rep Mike Rogers (R-Ala.), ranking member Rep Adam Smith (D-Wash.) and House Armed Services seapower and projection forces subcommittee leaders Rep. Trent Kelly (R-Miss.) and Rep. Joe Courtney (D-Conn.).
“The Department of Defense needs to immediately provide our committee with answers and a plan for how they will protect U.S. Navy vessels against tampering. Absolute transparency with Congress is essential.”

The Congressional query comes as the Navy and shipbuilder HII are gauging the scope of the ships that were affected overall. The number of in-service Virginia-class submarines that have been affected are in the “low single digits” and an ongoing analysis of under-construction Virginia, Columbia-class submarines and Ford-class aircraft carriers could stretch into October, a defense official told USNI News on Friday.

Earlier this year, quality assurance teams at Newport News discovered the sub-standard welds and reported the violations in procedure to both the Navy and the Department of Justice, according to a Friday statement on LinkedIn by Newport News president Jennifer Boykin.

“We recently discovered that the quality of certain welds on submarines and aircraft carriers under construction here at NNS do not meet our high-quality standards. Most concerning is that some of the welds in question were made by welders who knowingly violated weld procedures.” she wrote.
“We immediately put together a team made up of both internal and independent engineering and quality subject matter experts to determine the root causes, bound the issue and put in place immediate short-term corrective actions as we work through longer-term solutions.”

Boykin went on to say HII notified both the Navy and the Department of Justice on the sub-standard work.

In a Tuesday internal memo to senior Navy leaders, Assistant Secretary of the Navy for Research, Development and Acquisition Nickolas Guertin said the intentional nature of the procedure violations prompted HII to call the DoJ. Parts of that memo began circulating on social media prompting accusations of purposeful sabotage of the ships by workers, which several sources told USNI News, independent of Newport News, was not accurate and that there was no evidence of malicious intent from the shipyard workers.

In a separate statement to USNI News, HII said that while the shipyard workers had violated the welding rules, they did not have “malicious intent” to damage the submarines or aircraft carriers they were working on.

“We discovered through internal reporting that some welders knowingly circumvented certain welding procedures. Based on our initial investigation, there is no indication of malicious intent,” reads the statement.
“We do not tolerate any conduct that compromises our company’s values and our mission of delivering ships that safeguard our nation and its sailors.”

Neither HII nor the Navy have said when the initial faulty work was discovered.

While the assessment of the overall welds on the ships under construction could extend into next month, the Navy and HII now have the tedious task of reinspecting the welds and determining solutions.

Twice in the 2000s, the Navy mounted separate investigations into suspicious welds into then Northrop Grumman-managed Newport News Shipbuilding. In 2007, the Navy found welders used the wrong filler material in non-nuclear pipping on Virginia submarines. In 2009, the Navy had to reinspect the welds on nine submarines and four aircraft carriers after a shipyard inspector admitted to falsifying inspection reports, according to The Virginian Pilot.

The inspections can involve analyzing welds that are difficult to reach throughout a submarine or aircraft carrier. The subsequent weld checks after the 2009 investigation took years, USNI News understands.

Now it can be explained why the Houthis were able to sink the US aircraft carrier.
