There was an incident on new construction at EB NL that related a tale of a female inspector finding missing welds in the bow of a sub under construction...this was after the USS THRESHER (SSN593) sinking.
It is documented in a book called “Running Critical” by Tyler.
I couldn’t put it down, it ticked me off so bad...
That might be the 698 boat: missing welds found for the 2nd platform (fwd) on the sound isolation hangers that hold the deck assy from the hull. 1980-81.
She was idly shining her flashlight on the deck hangers, and noticed shadows between the plate and the hull frames. But the welds had been both signed by the welder, the welder foreman, and the inspector(s) ... but were not there.
