SUBSIM Radio Room Forums - View Single Post - Increasing crush depth to a theoritical value

Submarine crush depths were influenced by what shipyard built the sub. Electric Boat made good boats and Cramp boats were a little iffy--not generally popular boats to serve on. The best for depth were probably built at Manitowoc because they used a unique (at the time) method of welding the pressure hull. They rotated the hull while welding which allowed the welders to always weld down. This created better uniform strength.

Deepest dives I know of (by class):

Old S = ~280 feet (not sustained--they brought it back up ASAP).
P Class: Pollock went to 500 feet in an out of control dive (bow estimated depth was 550 feet). Again--they didn't stay down there...

Salmon/Sargo: Don't remember the deepest depth I've read on these. Easily 350 though.

Gato: The Puffer went through a sustained (~31 hours) depth charge attack and they remained at 500 feet for much of the time. The Puffer was a Manitowoc boat.

Balao: Tang went to 700 feet. It wasn't on purpose and they brought it back up. But O'Kane typically took it to 500 feet.

After the war many subs were used as targets. I have heard and read that some of the Balaos went well past 800 feet before the final implosion of the pressure hull. None-the-less, I would bet that there was a lot of leaks and blown fittings before getting that deep.

What I'd like to see is a formula for SH4 sub crush depths that puts in a random variable:

CrushDepth = TestDepth * 1.3 + X.
X = 0 to .5 of the classes test depth.

Not knowing exactly how deep I can go would certainly influence my decision making :hmm:. I've never figured out how to do it though.
