A wider beam has nothing to do with it...

637 and 688's have the same beam...

It has to do with what the original type of operations the boat was designed to do....

Besides, in the real world, you would almost always evade shallow.....

Do they have the same beam? I was under the impression the LA was slightly wider.

I was quoting some simple physics for pressure vessels, but a search has yielded that external pressure vessels are not as straight-forward to solve/design as internal pressure vessels. I shall rescind my previous comment since I am not a naval architect. But for an internal pressure vessel, the stress in the cylinder is proportional to the diameter of the cylinder.

Random information, my Permit class submarine went pop at 1350 feet. Maybe we could create a list of crush depths. And my hull was down to 50% thanks to RBUs.

Crush depth of the Skipjack: 1bout 1070 feet.
