Quick Answer: How far can a submarine go underwater?

What is the deepest a submarine has ever 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.

How deep can a submarine go before being crushed?

What is crush depth? 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.

Can a submarine sit on the ocean floor?

With but one exception, US nuclear submarines do not sit on the sea floor. As has been explained in other answers, too much sand, silt and other debris would be sucked in by the seawater cooling systems and cause a lot of problems. The one exception was the US Navy’s nuclear research submarine, NR-1.

Can you survive a submarine sinking?

There are two options available for the crew of a submerged disabled submarine (DISSUB); escape or rescue. Escape is the process where the DISSUB’s crew leaves the boat and reaches the surface without external assistance; while rescue is undertaken by outside parties who remove the trapped crew from the submarine.

Has a submarine ever hit a whale?

It happens on rare occasions. Whales make sounds that can be heard by the submarine sonar. Submarines usually try to avoid the whales, but on the rare occasions that a collision occurs, it is the whale that suffers the worst of it. The submarines suffer some damage, but it is like your car hitting a medium size …

Can you smoke inside 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. As with other branches of the military, smoking has long been a staple of Navy culture.

At what depth will water crush you?

Human beings can withstand 3 to 4 atmospheres of pressure, or 43.5 to 58 psi. Water weighs 64 pounds per cubic foot, or one atmosphere per 33 feet of depth, and presses in from all sides. The ocean’s pressure can indeed crush you.

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.

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.

Can a submarine survive a tsunami?

Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. Once a submarine is deep enough the conditions on the surface are not felt. However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern.

Has a US submarine ever sunk?

Nine nuclear submarines have sunk, either by accident or scuttling. Three were lost with all hands – the two from the United States Navy (129 and 99 lives lost) and one from the Russian Navy (118 lives lost), and these are also the three largest losses of life in a submarine.

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.

How dangerous are submarines?

The underwater environment is a dangerous one. Submarines face many perils of the deep. Even a small fire or gas leak inside a submerged submarine can have catastrophic consequences. A collision with another vessel or grounding may be much more serious for a submarine than for a surface ship.

Did anyone survive on the Kursk?

Seven days after the sinking, British and Norwegian divers finally opened a hatch to the escape trunk in the boat’s flooded ninth compartment but found no survivors. The Government of Russia and the Russian Navy were intensely criticised over the incident and their responses.

How do you escape a sinking submarine?

Locks allow submariners to escape by first climbing through an inner door or hatch and sealing it tightly behind themselves. They then partially flood the small volume before the outer hatch will swing open, but this two-door system means they do not need to flood the entire boat.
