US sub sinking 50 years ago led to safety changes

KITTERY, Maine (AP) — The first sign of trouble for the USS Thresher was a garbled message about a "minor difficulty" after the nuclear-powered submarine descended to about 1,000 feet on what was supposed to be a routine test dive off Cape Cod.

Minutes later, the crew of a rescue ship made out the ominous words "exceeding test depth" and listened as the sub disintegrated under the crushing pressure of the sea. Just like that, the Thresher was gone, along with 129 men.

Fifty years ago, the deadliest submarine disaster in U.S. history delivered a blow to national pride during the Cold War and became the impetus for safety improvements. To this day, some designers and maintenance personnel listen to an audio recording of a submarine disintegrating to underscore the importance of safety.

"We can never, ever let that happen again," said Vice Adm. Kevin McCoy, an engineer and former submariner who now serves as commander of the Naval Sea Systems Command in Washington, D.C.

This weekend, hundreds who lost loved ones when the Thresher sank will gather at memorial events in Portsmouth, N.H., and Kittery, Maine.

I worked a a submarine base in the 70's and we felt the aftershocks of the Thresher sinking every day. The Navy started a Level 1 program where every componemt, valve, fitting, joint that wa within three links to the outside was individually tracked, x-rayed and documented back to the manufacturere. It was a lot of paperwork but it was effective

My sister was dating a VP at LUKEN STEEL when this event happened.

As some of their product was making the watertight doors, let me tell yas, that event shook up that company bigtime.

As a kid, I remember the public speculation that the Russians had done something to the Thresher.
