<div>They are for a unreinforced sphere. I am no where near a good enough engineer to know the answer to that. I do know Phil Nuytten said you can chop up the sphere and weld it back together with a pattern that looks like a soccer ball which increases the strength a lot. I can't remember what he called it, but I believe there was a Japanese deep diver submarine that did this.</div>
