Question: How Deep Can Ww2 Submarines Go?

Can you smoke in 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..

Can a submarine survive a tsunami?

Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. … However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern. Large enough waves can cause a submarine to be pulled (sucked) up to the surface.

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 many US subs were lost in ww2?

Fifty-two submarines of the United States Navy were lost during World War II.

How do submarines control depth?

The exact depth can be controlled by adjusting the water to air ratio in the ballast tanks. Submerged, the submarine can obtain neutral buoyancy. That means the weight of the submarine equals the amount of water it displaces. … The submarine gains positive buoyancy, becomes less dense than the water and rises.

How long can a nuclear submarine stay submerged?

four monthsNuclear submarines can operate underwater for three or four months at a time and cross oceans with ease.

How many atmospheres can a human withstand?

100 atmospheresA person can withstand perhaps 100 atmospheres of pressure if they aren’t breathing air – divers do it. If they are breathing air, the limit is just a handful of atmospheres. Not sure exactly how many it takes before oxygen becomes toxic, though.

How long can a World War 2 submarine stay submerged?

After 48 hours, it would be unbearable and you would have to surface. The World War II submarine that had the longest possible underwater endurance was the German Type 21. It could stay down for up to 75 hours, which gives you a tad over 3 days.

Which submarine sank the most ships in ww2?

USS TangWith 33 ships sunk, the USS Tang sank the most tonnage of shipping in World War II for the United States. Its tonnage was revised from the Joint Army–Navy Assessment Committee (JANAC) report, which initially credited Tang with fewer sinkings.

Can a human dive to the Titanic?

Luxury travel company Blue Marble Private will offer diving expeditions to the world-famous Titanic wreck site beginning in May 2018. For a mere $105,129 per person, tourists can explore the wreck off the coast of Newfoundland, Canada during an 8-day expedition.

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 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.

What happens if you go too deep in the ocean?

The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse.

Can water pressure crush a human?

The pressure of the water on a deep-diver’s body can crush him. It can easily cause death. Coming up from the extreme pressure of deep water to the much lower pressure at the surface is especially dangerous. Ascending too quickly can cause a fatal condition called “the bends.”

How deep can a nuclear submarine go?

about 300mA 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.

At what depth will the ocean crush you?

The deepest point ever reached by man is 35,858 feet below the surface of the ocean, which happens to be as deep as water gets on earth. To go deeper, you’ll have to travel to the bottom of the Challenger Deep, a section of the Mariana Trench under the Pacific Ocean 200 miles southwest of Guam.

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 happens when a submarine reaches 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.

How deep can submarines go in the ocean?

800 feetWhat the Navy can tell you is that their submarines can submerge deeper than 800 feet. But they don’t go as deep as the research subs that explore the seafloor.

What is the deepest a nuclear submarine has gone?

The expedition reached a maximum depth of 10,928 meters / 35,853 feet deep, 16 meters/52 feet deeper than any previous manned dive. …

At what depth will water crush you?

At about 10–12 meters (33–40 feet) of depth, pressure of water column above you (1 extra atmosphere of pressure per 10 meters) will compress air spaces in your body by half, with lungs compressing the most by the absolute volume.
