Do submarines need to surface?

Submarines stay underwater for months – where do they get their oxygen and drinking water? Nuclear submarines can go months without surfacing. …air, of course, Very important, but let’s start with the water issue. Although sea water is too salty to drink, it works well in toilets.

Will the submarine surface?

One Way Submarines can surface Known as blowing to the surface. … a submarine has planes for the stern, bow and superstructure. By tilting them, the submarine can rise while cruising. Once on the surface, the low-pressure air forces the seawater out of the ballast tanks, causing it to float above the water’s surface.

How long does it take for a submarine to surface?
