How long do submarines stay underwater?

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.

What is the longest time a submarine has stayed submerged?

The longest submerged and unsupported patrol made public is 111 days (57,085 km 30,804 nautical miles) by HM Submarine Warspite (Cdr J. G. F. Cooke RN) in the South Atlantic from 25 November 1982 to 15 March 1983.

How long can a US nuclear submarine stay submerged?

Nuclear submarines can operate underwater for three to four months at a time and easily span seas. While few conventional submarines can travel the distance, none have the same depth of endurance below.

Do submarines run out of air?

A submarine is a sealed container that contains people and a limited supply of air. There are three things that must happen in order to keep air in a submarine breathable: Oxygen has to be replenished as it is consumed. If the percentage of oxygen in the air falls too low, a person suffocates.

How long can a Russian submarine stay underwater?

Diesel-electric submarines may remain immersed for up to 48 hours without recharging their batteries, but they should surface to operate a generator. Nuclear-powered submarines in the army may remain submerged for extended periods of time.

How long can a Submarine stay underwater?

Do submarines hit whales?

Most subs have two types of sonar: active and passive. Active sonar sends out acoustic sounds, or “pings,” which can reach thousands of yards. If the ping bounces back, that means it hit an object—like a whale, a ship, or another submarine.

What happens to poop on a submarine?

Usually it sinks by itself, but some scrap metal can be added to aid its journey to the bottom of the ocean. Therefore, yes, submarines do produce trash that is thrown out into the ocean and it is terrible.

Are submarines hot inside?

Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.

Are you allowed to smoke on a submarine?

Everybody is aware that smoking is a legal, if harmful, stress reliever. So the Navy banned smoking aboard submarines not with the stated purpose of curing the smokers, but of protecting nonsmoking submarine crew members from the threat of heart and lung disease from secondhand smoke.

Do submarines make their own oxygen?

Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.

How long could ww2 subs stay submerged?

Model of the USS Balao (SS-285) Fleet Submarine

Two 126-cell battery groups gave her a submerged top speed of 8.75 knots (16.2 km/hr); holding her speed to 2 knots (4 km/hr), she could remain submerged for 48 hours.

How fast do submarines go in mph?

The U.S. Navy's Los Angeles-class nuclear-powered attack submarines, improved variants of which remain service today, have an official top speed of 23 miles per hour when submerged. There have been reports that these boats can actually get up to around 35 miles per hour underwater.

How deep do Navy submarines go?

It's generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of 675–900m (2,250–3,000 ft).

Do you get seasick on a submarine?

Will I get seasick? Is it like being on a boat? Being on a submarine is very different to being on a boat. There is no rocking motion, as the submarine sits below the waves, and so people who get seasick on a boat will not do so on our submarine.

Can a submarine survive a nuclear bomb?

Submarines are also designed to withstand short pressure spikes from close explosions of deep charges and even nuclear explosions.

Does it stink in a submarine?

You are probably wondering why I would call this post such thing... Since Submarines remain submerged with a sealed atmosphere they rely on a chemical called Amine to remove the carbon dioxide. This chemical makes everything stink.

Do submariners take bath?

The showers on a submarine are set up much like the ones in your home, well kind of. They have hot and cold water access with a recirculation pump so that the water stays hot so that you can use it quickly and efficiently by minimising water usage.

Do submariners bath?

Surrounded by water, the most precious commodity inside the submarine is water. “ None of us take a bath till we reach a port for replenishing,” explains a junior officer of the Indian Navy. Since water is precious, it is used only for drinking and cooking.

Can submarines sit on the ocean floor?

Even since the early days of the nuclear sub program – dating back to Admiral Hyman Rickover himself – these submarines have been able to touch the bottom of the ocean, so long as that bottom wasn't below their crush depths.

How do submarines get fuel?

Submarines also need electric power to operate the equipment on board. To supply this power, submarines are equipped with diesel engines that burn fuel and/or nuclear reactors that use nuclear fission.

How many toilets are in a submarine?

Other concerns range from bathrooms and bunks to potential pregnancies. Aboard fast-attack submarines, two bathrooms - each with four toilets and two urinals - serve 100 crew members. Crew chiefs and officers use another three baths.

Can you drink on a submarine?
