German submarines – or unterwasser boats (U-boats) – were on a mission to destroy merchant vessels carrying supplies to allied forces in order to hinder their war efforts. Aided by intelligence reports on the location, destination, and speed of merchant vessels, the U-boats would search the seas for victims.
How many ww2 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 happened to the U-boats in ww2?
In World War II Germany built 1,162 U-boats, of which 785 were destroyed and the remainder surrendered (or were scuttled to avoid surrender) at the capitulation. Of the 632 U-boats sunk at sea, Allied surface ships and shore-based aircraft accounted for the great majority (246 and 245 respectively).
How long would ww2 U-boats stay underwater?
The typical U-boat was 214 feet long, carried 35 men and 12 torpedoes, and could travel underwater for two hours at a time.
What were U-boats called in ww2? – Related Questions
Did they shower on U-boats?
Washing and showering was not permitted, and no change of clothes. In such a confined space, with little hygiene, deodorant was used to control body odour. There was no privacy, and all space was filled – crew members even slept in the loading torpedo room.
What fuel did U-boats use?
Type IXC boats otherwise only carried 12 weeks of food supplies, and Type VIIC U-boat carried about 114 tons of diesel fuel.
What is the longest time 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.
How long can US nuclear submarines 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 long can a US submarine stay underwater?
The Submarine Force is often called “The Silent Service” because of how it operates. Submarines can submerge more than 600 feet below the ocean’s surface for up to four months at a time, constantly patrolling and working classified missions.
How many years can a submarine stay underwater?
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.
Why do Russian subs have windows?
The windows on the sail of submarines are used when it is on the surface as a windbreak and to be able to see what is ahead of you.
What do submarines do with human waste?
Waste that is discharged overboard must either be pumped out against the ambient sea pressure or blown out using pressurized air. Waste materials are collected and periodically discharged.
Can submarines sit on the ocean floor?
With but one exception, US nuclear submarines do not sit on the sea floor. As has been explained in other answers, too much sand, silt and other debris would be sucked in by the seawater cooling systems and cause a lot of problems. The one exception was the US Navy’s nuclear research submarine, NR-1.
Can you swim out of a submarine?
You can’t just open the door and swim out; you have to get into an escape trunk, flood it, open the outer hatch and hope your breathing apparatus works. It’s difficult, dangerous and not many people succeed. Originally Answered: When submarines sink why cant crew swim out?
How thick is the hull of a submarine?
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.
Why can’t you swim to the bottom of the ocean?
At a kilometre under sea level, the pressure is 1,500 pounds per square inch. That’s like the weight of a small car pushing on every square inch. Enough to kill you. 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.
Why you shouldn’t swim in the ocean at night?
In general, swimming at night is not very safe and not recommended. It is simply harder to see the conditions of the water and certain wildlife that might be lurking, like jellyfish. For those still looking to swim at night, staying close to the beach shore is an absolute must for all swimmers.
What is the deepest a human has been in the ocean?

Has any human touched the bottom of the ocean?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.
What was found in the Mariana Trench?
A recent study revealed that a plastic bag, like the kind given away at grocery stores, is now the deepest known piece of plastic trash, found at a depth of 10,975 meters (36,000 feet) inside the Mariana Trench.
