How deep can a US military submarine go?

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).

Why can’t submarines go to the bottom of the ocean?

At a kilometre under sea level, the pressure is 1,500 pounds per square inch. … So you can see how even machines have to be incredibly tough to be able to withstand that pressure without crumpling like an old pop can. Deep sea submarines – the ones that go deeper than anything else – have to have very thick hulls.

How long can a nuclear submarine stay underwater?

Endurance: Nuclear submarines can operate underwater for three or four months at a time and cross oceans with ease. While some conventional submarines can handle the distance, none have comparable underwater endurance.

How deep can a human dive in a submarine?

A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The research vessel Atlantis, shown at the surface, is 274 feet long.

What is crush depth for a human?

At what depth would a human be crushed? 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 the hull of a submarine?

Making the hull. 4 Steel plates, approximately 2-3 in (5.1-7.6 cm) thick, are obtained from steel manufacturers. These plates are cut to the proper size with acetylene torches.

What is the longest a submarine has stayed submerged?

Originally Answered: What is the longest recorded time that a submarine stayed submerged under water? The longest submerged cruise made public was by the HMS Warspite from November 1982 to march 1983. They stayed under water for 111 days.

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.

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.

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 metal is used in submarines?

High-strength alloyed steel is still the main material for submarines today, with 250–350 metres (820 to 1,148 feet) depth limit, which cannot be exceeded on a military submarine without sacrificing other characteristics. To exceed that limit, a few submarines were built with titanium hulls.

How do submarines get air?

Oxygen onboard a submarine is released either through compressed tanks, an oxygen generator, or by some form of an ‘oxygen canister’ that works by electrolysis. Oxygen is either periodically released throughout the day at specific time intervals or whenever the computerized system detects a reduction in oxygen levels.

How far can a submarine travel?

A nuclear submarine can dive to a depth of about 300m. This one is larger than the research vessel Atlantis and has a crew of 134. The average depth of the Caribbean Sea is 2,200 meters, or about 1.3 miles. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.

What is the top speed of a submarine?

There are established reports and manufacturer’s claims that would indicate two (or perhaps more) submarines are capable of speeds exceeding 30 knots (56 km/h). In 1965, USS Albacore reported a speed of 33 knots (61 km/h), but this was not an official record.

Where does poop go on a submarine?

So, what we do is all the poop and all the excrement and all that stuff goes into the sanitary tanks. There’s three sanitary tanks onboard a submarine. So what you have to do to discharge it is you have to pressurize a sanitary pump that blows the sanitary waste outside of the boat.

Can you smoke on a submarine?

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

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

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 they 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 WiFi?

For cyber-security reasons, the military generally prohibits personal use of military computers and networks. Computer equipment and networks for morale, welfare and recreation (MWR) are isolated from the systems required for the mission. There would be NO allowed personal use of wi-fi or bluetooth within a submarine.

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.
