Modern nuclear submarines have years of power in their reactor cores, and support equipment supplies water and keeps the air clean. There are, however, limits to the amount of provisions that can be stored aboard, and that limits time under water.
Nuclear Submarines can stay almost indefently for them it is a question of Stores (food). Diesel Submarines are really not designed for under ice operations. AIP Subs can stay submerged for prolonged periods depending on the amount of Liquid Oxygen it has.
It doesn't require oxygen to operate. That means there is no smoke exhaust and no need to surface to power electrical batteries. They can stay under water as long as their is food for the crew.
how long can garter snakes stay under water?
you cant. unless your a pro
they can't breathe under water
The submarines in WW2 are different from now. I have done research and back then submarines were easily sunk and were ran differently ! How were they ran differently ? Back then in WW2 the submarines used, were smaller ... They were ran by Diesel engines which allowed them to high surface speed and long range, but underwater it was very difficult and the speed and range wasn't the same from out of the water.
They can stay under water for 10 seconds.
yes it can but it cant go out of the water for long
I can put my face under the water for 20 seconds
a few of the sea animals cannot stay under water for a long time.
Submarines use sonar to detect other things in the water. Sonar is an acronym for sound navigation and ranging, but there is a bit more to this. Submarines use what is called active sonar and passive sonar. We need to look at it in a bit of detail to see what's up.Contemporary submarines have a active sonar system aboard. This system emits "pings" into the water, and the pings are bursts of sound energy. The sound energy propagates through the water, bounces off things around the submarine, and then returns to the submarine to be picked up and listened to. By "pinging" on things, the submarine can develop a profile of sorts of things around it. The bottom is down there, and there's another submarine over there. Something like that. But active sonar means you can be heard a long way away. Farther away than you can effectively "see" other submarines with that active sonar. Other submarines can "hear you coming" because you are pinging, and can do this before you can hear then with the returned pings. That's bad for the submarine using active sonar.Modern military submarines operate in water that is fairly deep. This means that the submarines don't generally have to worry about hitting anything under the water. As they on patrol, they are listening for other things in the water using their passive sonar array. This array uses the hydrophones to listen to the sounds in the water. These sounds are being made by other ships, other submarines, schools of fish, whales, or whatever else is making "noise" in the water. This is the primary method used by the current military submarines to locate and track other things in the water with them.
as long as they want until they need to spout the water
