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 long could a World War II submarines stay underwater?

The Germans' most formidable naval weapon was the U-boat, a submarine far more sophisticated than those built by other nations at the time. The typical U-boat was 214 feet long, carried 35 men and 12 torpedoes, and could travel underwater for two hours at a time.

How deep could a World War II submarine dive?

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 can a submarine 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. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged.

How long can a nuclear powered sub Stay submerged?

Nuclear submarines can operate underwater for three to four months at a time and easily span seas.

How long can a Submarine stay underwater?

What is the longest a submarine has stayed submerged?

What is the deepest a submarine has gone?

Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe which reached a record depth of about 10,911 metres (35,797 ft) in the Challenger Deep of the Mariana Trench near Guam in the Pacific.

Has a submarine ever hit a whale?

British Navy mistook whales for submarines and torpedoed them, killing three, during Falklands War. THE British navy killed three whales with torpedoes after mistaking them for enemy submarines. THE British navy killed three whales after mistaking them for enemy submarines during the Falklands War, it has been revealed ...

What do submarines do with human waste?

Most bigger submarines have something called “Trash Disposal Units”, which are exactly what you think you are. Somewhere in the submarine there is a long tube or a shaft, which has a ball valve separating it from the ocean. Crew members have to assemble canisters from pre-punched galvanized, perforated steel sheets.

Can a submarine survive a nuclear bomb?

Most current submarines can survive at a depth of 400 m, so they might survive long pressure spikes created by the waves above them as high as 200–400 m, but not kilometer size waves. Submarines are also designed to withstand short pressure spikes from close explosions of deep charges and even nuclear explosions.

At what depth will water crush you?

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. The 40% of non-water non-gaseous minerals and tissues such as salts, proteins, fats and lipids are virtually impossible to compress similar to water.

What happens if a submarine goes too deep?

The name is foreboding and fairly self-explanatory; it's when the submarine goes so deep the water pressure crushes it, causing an implosion. The crush depth of most submarines is classified, but it's likely to be more than 400 metres.

How much fuel did a ww2 submarine carry?

“This boat has the ability to store up to 110,000 gallons of raw dirty bunker fuel for all five of the diesels.” One such submarine with the reliable power plant engine was the USS Pampanito (SS-383), a World War II Balao class Fleet submarine built from 1942 to 1944.

How many German U-boats are still missing?

A U-boat of this type, listed for decades as being sunk off Gibraltar, was found on the sea bottom about 60 miles off the coast of New Jersey in 1991. According to the definitive website Uboat.org, a total of 50 German U-boats remained unaccounted for after the end of World War II.

How many subs did us lose in ww2?

Fifty-two submarines of the United States Navy were lost during World War II.

Can you smoke inside a submarine?

April 8, 2010— -- Life aboard a submarine may soon get a little harder to take for thousands of sailors. The Navy announced today a ban on smoking aboard submarines while they are deployed below the surface after medical testing showed non-smokers suffered effects of second-hand smoke. It will take effect by Dec.

What do submarines smell like?

Some submarines smell like Cinnabon.

One of them is food—better food than you'll find if you were stationed elsewhere. The military spends more money on food on subs than it does on regular Navy ships.

Do you get seasick on submarines?

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.

Do submarines have air conditioning?

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.

Why do they whisper in submarines?

Silent running is a stealth mode of operation for naval submarines. The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise.

Is K 19 Widowmaker a true story?

July 19 marked the first major motion picture release by the National Geographic Society. K-19: The Widowmaker is based on the true story of a near-disaster aboard the Soviet Union's first nuclear ballistic submarine.

How thick is a submarine hull?

Making the hull. 4 Steel plates, approximately 2-3 in (5.1-7.6 cm) thick, are obtained from steel manufacturers.

Has anyone dove to the bottom of the Mariana Trench?

On 23 January 1960, two explorers, US navy lieutenant Don Walsh and Swiss engineer Jacques Piccard, became the first people to dive 11km (seven miles) to the bottom of the Mariana Trench. As a new wave of adventurers gear up to repeat the epic journey, Don Walsh tells the BBC about their remarkable deep-sea feat.
