As far as the ships are concerned I served aboard a late 50's/early 60's era DDG (ex DLG that was reclassified) from '87 to '89. The old girl's hull took a heck of a beating when we went through a class 4 Hurricane in the mid Atlantic, but we came out of it alright. A few months later we went into the yards to get some work done and they had to cut a hole in the starboard side of the hull to remove some equipment from the forward fireroom. Being on a 'warship' you'd think that the sides of the ship would be fairely thick but from what I can remember, at the point where the hole was cut which was just above the waterline, there was nothing but a piece of 1/2 plate. Like I said we made it through a heck of a storm where we were encountering waves that came close to putting watrer down the forward stack, knocked the steps off nearly every exterior ladder (stairway), knocked a 6 inch fire riser off the deck just forward of the 5" gun mount, not to mention picking up a 600 lb plus J bar davit from midships and depositing it on the fantail. It was so bad you had to drag your feet to walk because the deck would drop out from under you if you tried to take an actual step, and side to side you could stand at the bottom of the ladder in the engine room and grab the rails as the ship rocked away from you and one good step when it rocked back would put you on the upper level. Ultimately the only way to describe it accurately would be to say it was one HE!! of a ride.......They did a pretty detailed inspection of the hull while we were in the yards, in drydock, and the only major thing they found wrong was a crack in a weld on a support brace in the forward engine room that hadn't been there before the storm.

That said it amazes me that regardless of how the hull was put together be it rivited or welded, it's amazing that any of them can withstand the punishment they encounter day in and day out.
