Ummm wait a minute.. They didnt weld the hulls all the way around on the early boats? How the heck were they water tight without welds going all around them? Did they use seals and crap instead of relying on tougher welds?? |

Here's a snippet:
Between 1932 and 1941, Portsmouth built an additional 22 submarines in the 1500-ton category. It was during this period that the first all-welded submarine, USS Pike (SS-173), was completed. The welded hull allowed Pike to submerge to much greater depths than her predecessors and at the same time provided greater protection against depth-charge attacks.
