April 10 marks the 62nd anniversary of the loss of U.S. Navy submarine Thresher (SSN 593) at sea. In all, 129 officers, crew and civilians lost their lives as a result of the disaster. Although Newport News Shipbuilding did not build Thresher, the tragedy is an important reminder that quality work at NNS keeps the Navy safe.

During sea trials following an overhaul, Thresher began deep dive tests off the New England coast. At 9:13 a.m., the crew reported they were experiencing minor difficulties. Communications with the submarine were lost at about 9:15 a.m. At 9:18 a.m., the sea trials escort ship heard sounds believed to be the pressure hull imploding. An investigation concluded the loss of Thresher was most likely the result of a failed piping joint.

As a result, the Submarine Safety program – known as SUBSAFE – was formed to keep safety and quality at the forefront of shipbuilding. Today, SUBSAFE remains central to all submarine design, construction and maintenance work at NNS.

All NNS shipbuilders will receive “This is My Purpose” pocket badges next week. Shipbuilders are encouraged to insert a loved one’s photo to serve as a constant reminder of the importance of quality and safety.

Commemorative banners also are on display throughout the shipyard.

At 9:15 a.m., Thursday, April 10, NNS will sound the shipyard whistle and observe and moment of silence to mark the tragic anniversary. Second-and third-shift teams are asked to observe a moment of silence at the start of their crew talk or team meeting.
