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.
How many US subs were lost in ww2?
Fifty-two submarines of the United States Navy were lost during World War II.
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.
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.
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.
Why do submarines not have windows?
There is no light 2-4 hundred meters under water. However, the submarines sometimes stay closer to the surface and could have their own light sources. Why don’t they have windows? … A pressure vessel, such as a submarine, can only be strong if it’s intact.
Which country has the best submarines in ww2?
Glider The Best Submarine of the war was without question is the German Type XXI. The Best submarine in service in numbers during the war were the American Fleet submarines. I would suggest that the best submarine at the start of the war 1939 was from from Poland.
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.
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.
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 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.
Is smoking allowed on Navy ships?
Smoking is allowed in designated areas on Navy ships and at Navy and Marine Corps installations, and Mabus’ proposal would not change that. Smoking has been prohibited on submarines since December 2010. Cigarettes in military rations were discontinued in the 1970s. … “And you are seeing smoking going down.”
What is the deepest a submarine can go?
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.
Can u boats go underwater?
Click here now. Unlike nuclear submarines, which could dive to depths of over 1,000 feet, travel thousands of miles submerged and remain on patrol for months at a time, the u-boat can operate submerged only for brief periods at a time.
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.
