[null and void]

The result of the Thresher sinking was Portsmouth never built another boat. They completed what was on their ways and all the work they got after that was repair after an extensive retraining program.

IIRC, there were some severe (union) labor problems while the Thresher was being built. I'd heard from a couple sources that the loss was caused by a valve stem being cut most of the way through.

I do believe it was main sea water piping that gave way at the silver brazing point. This is a huge braze joint, SS pipe to HY-80 hull. Would have resulted in a 10" ID hole spraying water everywhere and shorting out the SSTG's which scrammed the reactor.
