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.
