It was 45 years ago today that we lost the first of two nuclear submarines.
The USS THRESHER (SSN593), the first of a new class of fast attack submarines, was lost with all hands while conducting sea trials off the coast of Massachusetts.
The Navy quickly figured out what went wrong and made some sweeping operational and material changes (to include implementation of the SUBSAFE Program) which significantly enhanced subarine operations.
There will be a memorial service this Saturday in Kittery, ME.

BN….
is that a history post you just wrote??
Won’t catch me writing any mechanical engineering posts, I can promise you that!
Yep.
Got another one for tomorrow…
And don’t sweat it: I’ll pick up the slack for you non-engineers.
