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..
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.
Do submarines run out of air?
A sub is actually far more self sustaining than the space station – due to the nature of water availability. The ISS WILL run out of air (oxygen) if it’s not periodically replenished, either as oxygen, or as water to make it from. As long as the reactor is running, a nuclear-powered submarine will NEVER run out of air.
Who has the most advanced submarine in the world?
The $2.6 billion USS South Dakota (SSN 790), seen here in a photo illustration, is the newest, most-advanced addition to the US Navy’s Virginia-class fleet of nuclear-powered, fast-attack submarines.
Which is the biggest submarine in the world?
The typhoon class submarines of the Russian navy are the largest submersible ships that have ever been built. More specifically, a Russian submarine known as Dmitriy Donskoy, TK-208, is the world’s largest submarine.

How deep can Russian submarines go?
8,200 to 20,000 feetPolmar said there was “nothing in the U.S. fleet to match” the depths that the Losharik can take its crew. Various reports, he said, place the mysterious craft’s maximum depth at anywhere from 8,200 to 20,000 feet.
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. … Mark Jones of the Commander Naval Submarine Forces out of Norfolk, Va., said about 40 percent of the submarine sailors are smokers.
How many 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.
What do submarines do with human waste?
Originally Answered: What do submarines do with human waste? Waste is “deposited” in septic tanks. At appropriate times at sea the effluent is blown to sea by compressed air. In port the tanks are pumped ashore to a collection unit.
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.
Which country has the most advanced submarine?
A Russian military submarine. North Korea has 83 submarines, which is more than any other country in the world.
How deep can a World War 2 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).
Has a submarine ever hit a whale?
Here’s a question that you don’t hear very often; if a submarine and a whale collided, who would emerge victoriously? The answer to that is not definite because such an incident has not occurred so far. However, back in 2005, the USS San Francisco did collide with a seamount at full speed.
Can you survive a tsunami in a submarine?
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. … Large enough waves can cause a submarine to be pulled (sucked) up to the surface. This is called broaching, this is not a good thing.
Do submarines have WiFi?
Even when a submarine is on the surface, the crew’s access to the internet is severely restricted. … There would be NO allowed personal use of wi-fi or bluetooth within a submarine. The vessel MIGHT have a wired LAN for MWR, protected against signal leakage or intrusion.
Has anyone survived a submarine sinking?
All of the 72 crew made it to the surface but only 15 survived with the rest swept out to sea by the tide and lost. … Of the Soviet submarine’s 69 crew, 34 of those who made the ascent to the surface later died from hypothermia, heart failure or drowning.
What happens to a submarine at crush depth?
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.
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.
Can a blue whale sink a cruise ship?
Regarding this, can a blue whale sink a cruise ship? … A pretty small fishing boat, it could probably damage, or cause to sink if it leapt out the water, and landed on it, but a battleship, ferry, or cruise liner can omit whales from their list of sinking hazards.
How many nuclear submarines are at the bottom of the ocean?
Nine nuclear submarines have sunk, either by accident or scuttling. The Soviet Navy has lost five (one of which sank twice), the Russian Navy two, and the United States Navy (USN) two.
