Make Your Stomach Ache Go Away. Stomach aches, otherwise known as abdominal pain, are one of the most annoying maladies that can affect almost anyone at anytime in their lives. There are endless causes for stomach aches and the most frequent causes will be discussed here.
2)HULL CAPACITY. Hulls are special structures in a submarine to hold water in them which help the submarine to maintain buoyancy underwater. The deepest a submarine can go is about 3 km underwater(I dunno if modern technology has surpassed that level or whatever).
All submarines are limited solely by the amount of food onboard. Toward the end of a deployment, the meals get interesting (chili mac with a side of canned beets, for example). The longest that I've been submerged was about four months, followed by two quick port visits, followed by two months at sea.
