As submarines go deeper they are surrounded by more and more pressure from the water arround them. There are not currently any submarines that can withstand that amount of water pressure.
They caused anxiety and sink ships.
No, hurricanes do not affect submarines operating below the surface. Sea conditions do not affect submarine operations because, in general, they run deep enough to avoid the swell on and near the surface.
if it aint regulated you would suffercate
To protect the occupants from extreme pressure.
To withstand the external pressure.
Submarines cannot reach the deepest parts of water because of the pressure or water and deepest surface is not a smooth, its full of rocks and sea plants.
To withstand high water pressure when they are submerged at sea.
Pressure can affect the solubility but the effect is not important.
because they have to withstand the pressure of the water when they go down under water. and to keep the people safe :)
Submarines don't have windows, at least not any that are used for viewing outside of the hull while submerged. They are used in some submarines as bridge viewing windows, but they're subjected to ambient sea pressure when the boat submerges, not direct sea pressure like the hull is.
The two US submarines lost after their hulls were crushed were the USS Thresher and the USS Scorpion. They are SSN-593 and SSN-589, respectively.
