The internal bulkheads on the wartime boats that separated the different compartments were rated to the same strength as the pressure hull. As to the exact thickness I don't have the figure.
On some of the post-war submarines (like my Darter) the bulkheads were thinned out to save overall weight. This resulted in a crush depth for the bulkheads of about half what the outside pressure hull was. In other words, as long as the boat was dry internally, you were okay. But flood a compartment and the bulkhead would collapse long before the rest of the pressure hull would. It kind of invalidated the whole reason for having a watertight bulkhead to begin with, if you ask me.
Well, as we used to say, as long as the number of surfaces equaled the number of dives, you were good to go!!
