Quick Answer: How long can a nuclear sub stay submerged?

What is the longest time a submarine has stayed submerged?

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.

How deep can nuclear subs go?

A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 13 miles.

Do nuclear submarines need to surface?

Nuclear submarines do not have to surface, and generally do not for the duration of a patrol. Occasionally they may need to run on the emergency diesel engine and will do so at periscope depth.

How long could a ww2 submarine stay underwater?

After 48 hours, it would be unbearable and you would have to surface. The World War II submarine that had the longest possible underwater endurance was the German Type 21. It could stay down for up to 75 hours, which gives you a tad over 3 days.

How do submarines get rid of human waste?

Waste that is discharged overboard must either be pumped out against the ambient sea pressure or blown out using pressurized air. Waste materials are collected and periodically discharged.

Why do submarines not have windows?

There is no reason to have a window because submarines are submerged almost all the time. Besides, there is nothing to see. Submarines operate in open ocean and stay away from any kind of ocean floor. Using external lights to allow people to look through a window would defeat the purpose of being stealthy.

What is the deadliest submarine in the world?

The World’s Five Most Dangerous Submarines

  • Ohio-class Ballistic Missile Submarine.
  • Columbia-class Ballistic Missile Submarine.
  • Project 955 Borei-class Ballistic Missile Submarine.

  • Project 667BDRM Delfin class (Delta IV) Ballistic Missile Submarine.
  • Project 885M Yasen class Guided Missile Submarine.

How deep underwater can a human go?

That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.

What is crush depth for a human?

Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

How long can a sub stay under?

The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged.

Are submarines faster on the surface or underwater?

Yes, as Larry has succinctly pointed out with a neat cross reference, the modern submarine travels faster underwater than on the surface. Since the pre-nuclear subs would therefore be spending most of their time on the surface of the sea, it made sense to give them a shipshape, seaworthy hull form for best speed.

What happens if a nuclear-powered ship sinks?

It sinks and sits in the cold water of the deep sea. The reactors are designed to shut down automatically upon a loss of electrical power (which will happen pretty quickly if the boat floods and sinks), and emergency systems will keep the reactor from melting down.

Which submarine sank the most ships in WW2?

With 33 ships sunk, the USS Tang sank the most tonnage of shipping in World War II for the United States. Its tonnage was revised from the Joint Army–Navy Assessment Committee (JANAC) report, which initially credited Tang with fewer sinkings.

How deep could a WW2 submarine go?

World War II German U-boats generally had collapse depths in the range of 200 to 280 metres (660 to 920 feet). Modern nuclear attack submarines like the American Seawolf class are estimated to have a test depth of 490 m (1,600 ft), which would imply (see above) a collapse depth of 730 m (2,400 ft).

How long could a Uboat stay submerged?

Originally Answered: How long can a WW2 uboat stay under water? Under normal operations, roughly 24 hours; in emergency (with crew remaining still and minimizing even their talking, up to 72. The U boat was just that. A small ship with the capability to travel underwater for a limited time, not a true submarine.
