The longest submerged cruise made public was by the HMS Warspite from November 1982 to march 1983. They stayed under water for 111 days. The USN ballistic missile submarines routinely stay submerged for 90 days at a time, at least they did when I was in the navy in the early 1980’s.
although, How fast can submarines go underwater?
How Fast Can a Submarine Go? This is classified as well. However, U.S. nuclear-powered submarines can go faster than 23 miles per hour, which is 37 kilometers per hour or 20 knots (nautical miles per hour) underwater.
equally important, Why do submarines not have windows?
There is no light 2-4 hundred meters under water. However, the submarines sometimes stay closer to the surface and could have their own light sources. Why don’t they have windows? … A pressure vessel, such as a submarine, can only be strong if it’s intact.
otherwise What happens if a submarine goes too deep?
Originally Answered: What happens when a submarine goes too deep? If a submarine goes below their crush depth, eventually the pressure is beyond what the hull can handle and the submarine breaks open. The pressure wave immediately killes everyone onboard and the submarine sinks to the bottom.
Can you survive a tsunami in a submarine? 2. The ocean could be affected by high tsunami and/or pressure waves in the case of a large asteroid or comet impact. Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves.

Why do submarines not get crushed?
Because submarines are made of metal, and metal can only withstand a certain amount of pressure before buckling or collapsing, the strength of the metal and the design of the sub determines its ultimate depth limit. In reality, a submarine pilot would never take a sub anywhere near that depth.
How deep do most submarines go?

Can a submarine survive a tsunami?
Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.
