## 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 it gets crushed?

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).

## What happens when a submarine goes too deep?

Originally Answered: What happens when a submarine goes too deep? The pressure outside of the pressure hull overcomes the compression strength of the metal hull and suffer a catastrophic hull breach/collapse and sinks to the bottom.

## Can a submarine sit on the ocean floor?

Originally Answered: Can a submarine go to the bottom of the ocean? Yes, in areas where the depth is generally less than 2000 feet. Not good for then to sit directly on the bottom as coolant water intakes and other hull openings can get clogged. Research suns can go very very deep.

## How thick is a submarine hull?

2 to 4 millimeters
The external hull, which actually forms the shape of submarine, is called the outer hull, casing or light hull. This term is especially appropriate for Russian submarine construction, where the light hull is usually made of steel that is only 2 to 4 millimeters thick, as it has the same pressure on both sides.

## Do submarines collide with whales?

first off, “giant whales” aren’t that “giant” compared to even a small military submarine, much less a surface ship. Yes, whales collide with ships semi often, and it always ends up the same way.

## How many 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.

## Do submarines leak?

There is one leak during regular operation though. The shaft that transmits the power from the motor to the propeller have to pass through the hull, and rotating seals are hard to make 100%. It slowly drips water along the shaft, which is collected in a little bowl to be occasionally emptied when surfaced.

## What is the temperature on a submarine?

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.

## How long can a submarine stay submerged?

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 deep can you escape from a submarine?

600 feet
Modern submarine deep escape systems are effective down to a maximum depth of 600 feet. To give an idea of just what that means, open water certification on scuba gear allows you to dive to 60 feet. Advanced divers can go to 130 feet.

## Are submarines faster than ships?

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). Nuclear powered aircraft carriers have disclosed top speeds around 33 knots.

## 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.

## Can a submarine flip over?

It is technically possible for a submarine to flip over. Some of the early teardrop hull subs were hydrodynamically unstable. During high speed full rudder turns it could possibly heel over to the point it could roll. The navy issues restrictions on these submarines on turning these subs at high speeds.

## Can you smoke on a submarine?

No one can smoke on US submarines because it’s been prohibited since December of 2010.

## How often do submariners shower?

How long and often can one shower for in a submarine? On a US nuclear sub, you take a shower every single day unless the evaporator is secured for a reason. In fact, the Chief of the Boat (COB) will usually demand you take a shower if you smell like sweat.

## How do you do laundry on a submarine?

So the water is taken from the ocean, then is purified and undergoes electrolysis to get the salt out. Then it goes into washing machines, showers and the kitchen tap. Each crew member has his own laundry bag and they take turns operating the machine.

## Do submarines have black boxes?

These black boxes are also designed to “survive” under water for indefinite periods of time, as they are hermetically sealed. The pingers are supposed to last at least 30 days, although there are many examples where the the knocking lasted much longer.

## How many toilets does a submarine have?

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.

## Are submarines hot inside?

Modern submarines are mostly cool, that is in the fwd compartments where much of the navigational and sensor equipment is sited. This equipment needs to be kept cool. Back Aft in the engine room and after compartments can be very hot as there is a lot of machinery running.

## What do they eat on submarines?

The menu of sailors on the submarine has always been practically misleading: they have canned food in their galley with pig tongue in jelly, meat of ducks and turkeys, ham, red caviar, cod liver, sprat, saury or pink salmon.

## Do submarines stink?

Submarines develop a funk that is a mixture of many things. Combine, the smell of hot grease and hydraulic oil with that of diesel fuel, amine ( used to remove CO2, which smells like ammonia), with the combined sweat of a 100 persons.

## Do submarines have WIFI?

No, they don’t have internet access while submerged. They do have a form of radio communication while submerged – VLF, or Very Low Frequency . It’s a very low bit rate form of communication, only good for sending short messages, like orders.

## How many heads does a submarine have?

The Operations compartment had 4 heads. One middle level forward was a crews head serving the enlisted personnel that had 3 sinks, 3 shitters and 2 showers.
