How deep can 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).

What happens if you go too deep in the ocean?

As you descend, water pressure increases, and the volume of air in your body decreases. This can cause problems such as sinus pain or a ruptured eardrum. As you ascend, water pressure decreases, and the air in your lungs expands. This can make the air sacs in your lungs rupture and make it hard for you to breathe.

How fast can a submarine go underwater?

How Fast Can a Submarine Go? This is classified as well. However, U.S. nuclear-powered submarines can go faster than 23 miles per hour, which is 37 kilometers per hour or 20 knots (nautical miles per hour) underwater.

Can you smoke on a submarine?

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. … Mark Jones of the Commander Naval Submarine Forces out of Norfolk, Va., said about 40 percent of the submarine sailors are smokers.

How do submarines get air?

Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of “oxygen canister” that releases oxygen by a very hot chemical reaction. … The carbon dioxide is trapped in the soda lime by a chemical reaction and removed from the air.

Do submarines have AC?

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. … Submarines usually carry up to 75 personnel on board during its journey into the sea.

How long can a Trident submarine stay submerged?

The nuclear submarine that can remain underwater for 25 years.

What happens if someone dies in a submarine?

If the deceased died on land or has been returned to shore after death, the remains may be brought aboard either in a coffin or in an urn after cremation. The ceremony is performed while the ship is deployed, and consequently civilians are not allowed to be present.

What does a submarine do underwater?

Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink and surface at will. To control its buoyancy, the submarine has ballast tanks and auxiliary, or trim tanks, that can be alternately filled with water or air (see animation below).

Who has the fastest submarine?

K-222 was laid down on 28 December 1963 and commissioned on 31 December 1969, at Severodvinsk. It was assigned to the Soviet Red Banner Northern Fleet for the duration of her career. It was the world’s fastest submarine, reaching a record submerged speed of 44.7 knots (82.8 km/h; 51.4 mph) on trials.

Why do submarines not get crushed?

Because submarines are made of metal, and metal can only withstand a certain amount of pressure before buckling or collapsing, the strength of the metal and the design of the sub determines its ultimate depth limit. In reality, a submarine pilot would never take a sub anywhere near that depth.

Can a human survive 47 meters underwater?

According to the US Navy dive decompression tables a diver may spend up to five minutes at 160′ (47 meters) without needing to decompress during their ascent. The longer a diver stays underwater the greater their exposure to “the bends” becomes. … The bubbles can cause the bends.

What is the fastest speed underwater?

The British Spearfish torpedo designed to counter high-speed Russian submarines, such as the Alfa-class submarine, is reputed to have a speed in excess of 70 knots (130 km/h). The Russian rocket-powered supercavitating torpedo VA-111 Shkval is reportedly capable of speed in excess of 200 knots (370 km/h).

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 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.

What is the fastest US submarine?

USS SeawolfThe fastest U.S. submarine, the USS Seawolf (SSN-21), is believed to reach up to 35 knots. Electric boat is reportedly working on an underwater craft capable of transporting Navy Seals at speeds up to 100 knots (185 kph / 115 mph) using supercavitation.

Do any airlines still allow smoking?

CONCLUSION. So, do any airlines still allow onboard smoking? The answer is no.

What is the longest 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.

Can a torpedo sink an aircraft carrier?

The new class of speedy torpedoes can’t be guided, but can fire straight toward US Navy carriers that have little chance of detecting them. Torpedoes don’t directly collide with a ship, but rather use an explosion to create an air bubble under the ship to bend or break the keel, sinking the ship.

How far can a torpedo go?

It could travel about 180 metres (200 yd) at an average speed of 6.5 knots (12.0 km/h). The speed and range of later models was improved by increasing the pressure of the stored air. In 1906 Whitehead built torpedoes that could cover nearly 1,000 metres (1,100 yd) at an average speed of 35 knots (65 km/h).

Can a submarine flip over?

It is technically possible for a submarine to flip over. … The navy issues restrictions on these submarines on turning these subs at high speeds. however if it did roll over, the submarine was done for. The reason is that a submarines ballast tanks act like an upside down cup in a bathtub.

How thick is the glass in a submarine?

The result is that a glass sphere about four-to-six inches (10-15cm) thick should be able to withstand most of the blows of ocean exploration.

Is a submarine faster than a ship?

A submarine can be faster than a boat. … Nuclear power allows submarines to go faster than surface ships. (This may be true.) The fastest submarine is claimed to be the Soviet K-162, launched in 1969, with a top speed of 44.7 knots (82.8 km/hr).

Where does poop go on a submarine?

Although sea water is too salty to be consumed, it works perfectly well in the toilet. You do your business, flush and the waste is collected in a special tank somewhere in the bottom of the pressure vessel. Once it’s full, the waste is ejected using compressed air. Yes, the sailor poop goes straight into the ocean.

How do submarines dispose of human waste?

“Sanitary Tanks” inside the pressure hull hold the waste water from toilets, showers, etc and is usually pumped overboard. Submarines can also empty some of the sanitary tanks by pressurizing them and discharging them overboard.

Why do submarines have no windows?

However, the submarines sometimes stay closer to the surface and could have their own light sources. Why don’t they have windows? … A pressure vessel, such as a submarine, can only be strong if it’s intact.

Can you vape on a submarine?

The Navy is banning all electronic cigarettes and vaping devices from its aircraft, ships, boats, and submarines after a string of incidents caused physical injuries to sailors. … “These devices pose a significant and unacceptable risk to Navy personnel, facilities, submarines, ships, vessels and aircraft.”

How deep can a human dive without being crushed?

The need to do decompression stops increases with depth. A diver at 6 metres (20 ft) may be able to dive for many hours without needing to do decompression stops. At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed.
