Lawmakers to Investigate Faulty Sub, Carrier Welding at Newport News Shipbuilding

USNI News, Sam LaGrone, September 27, 2024

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………………………………………………………………………………………….

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.  https://news.usni.org/2024/09/27/lawmakers-announce-investigation-into-faulty-submarine-carrier-welding-at-newport-news-shipbuilding-ships-affected-in-low-single-digits-officials-say
