How deep can a ww2 submarine go?
World War II German U-boats of the types VII and IX generally imploded at depths of 200 to 280 metres (660 to 920 feet).
Which is the deepest ocean?
How thick is a submarine hull?
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.
What is under the ocean floor?
Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
What lives in the Mariana Trench?

Can a human dive to the Titanic?
No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure. The increasing water pressure also restricts blood flow by constricting tissue.
What’s the deepest someone has free dived?
No Limits Freediving (NLT)
Herbert Nitsch set a new record in 2007 by diving to a depth of 214 meters, earning him the title of “The Deepest Man on Earth”.
How deep the ocean actually is?
The average depth of the ocean is about 3,688 meters (12,100 feet). The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
How far can a torpedo go?
It could travel about 180 metres (200 yd) at an average speed of 6.5 knots (12.0 km/h). The speed and range of later models were improved by increasing the pressure of the stored air.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
Are there any diesel submarines left?
There is still no such thing as an operational 30-knot diesel submarine — on primary propulsion or batteries. Running at maximum speed submerged depletes the battery at an exponentially higher rate than the far more efficient five knots or less.
Why do Russian subs have windows?
The Russians use this feature due to longer surface transits in cold/artic conditions. It is a free flood area when submarged, subjected to sea pressure on both sides of the clear plastic window to keep it from breaking.
Is there deeper than Mariana Trench?
The deepest place in the Atlantic is in the Puerto Rico Trench, a place called Brownson Deep at 8,378m. The expedition also confirmed the second deepest location in the Pacific, behind the Challenger Deep in the Mariana Trench. This runner-up is the Horizon Deep in the Tonga Trench with a depth of 10,816m.
What happens if you dive too deep?
This can cause tissue and nerve damage. In extreme cases, it can cause paralysis or death if the bubbles are in the brain. Nitrogen narcosis. Deep dives can cause so much nitrogen to build up in the brain that you can become confused and act as though you’ve been drinking alcohol.
How deep can a human dive before being 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 deep can a human dive with a pressure suit?
An atmospheric diving suit allows very deep dives of up to 610 metres (2,000 ft). These suits are capable of withstanding the pressure at great depth permitting the diver to remain at normal atmospheric pressure. This eliminates the problems associated with breathing high-pressure gases.

Could Megalodon live in the Mariana Trench?
Let’s look at the idea that Megalodon could be living at the bottom of the Mariana trench, the theory popularised by the “Meg” book series and its film adaptation. Sorry folks, this is impossible. For one, no shark has ever been recorded living down there, let alone one as big as a Megalodon.
Is Megalodon still alive in Mariana Trench?
No. It’s definitely not alive in the deep oceans, despite what the Discovery Channel has said in the past,’ notes Emma. ‘If an animal as big as megalodon still lived in the oceans we would know about it. ‘
Can the ocean freeze?
Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes.
Why is the Mariana Trench so deep?
One reason the Mariana Trench is so deep, he added, is because the western Pacific is home to some of the oldest seafloor in the world—about 180 million years old. Seafloor is formed as lava at mid-ocean ridges. When it’s fresh, lava is comparatively warm and buoyant, riding high on the underlying mantle.
What is the biggest creature in the Mariana Trench?
Scientists have formally identified a new species of snailfish, the deepest ever caught in the Mariana Trench. A related species has been filmed but never collected. VIDEO: This small deep sea creature can withstand more water pressure than 1,600 elephants standing on its head.
How thick is the skin 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 millimetres thick, as it has the same pressure on both sides.
Are submarines designed to look like whales?
The new Nautilus, as envisioned by young designers and engineers from technology nonprofit UKNEST, looks like a cross between a manta ray and a whale. Like an actual fish, flexible wingtips facilitate the vessel’s steering. A selection of drones accompany the mothership for defence and attack purposes.
Are submarines double hulled?
All small modern submarines and submersibles, as well as the oldest ones, have a single hull. However, for large submarines, the approaches have separated. All Soviet heavy submarines are built with a double hull structure, but American submarines usually are single-hulled.
Are there humans living under the sea?
Underwater habitats are underwater structures in which people can live for extended periods and carry out most of the basic human functions of a 24-hour day, such as working, resting, eating, attending to personal hygiene, and sleeping.
Who owns the ocean floor?
It says that a country may claim an area extending 12 nautical miles from its coast as its own territorial sea. Additionally it can exploit 200 nautical miles of the water column beyond its coast as its exclusive economic zone. The same applies to the first 200 nautical miles of the sea floor, the continental shelf.
Is the ocean ever still?
Despite its size and impact on the lives of every organism on Earth, the ocean remains a mystery. More than 80 percent of the ocean has never been mapped, explored, or even seen by humans. A far greater percentage of the surfaces of the moon and the planet Mars has been mapped and studied than of our own ocean floor.
Who owns the Titanic right now?
In 1994, the company RMS Titanic Inc., a subsidiary of Premier Exhibitions, became the wreck’s salvor-in-possession—the only company allowed to collect artifacts. The company has now collected more than 5,500 artifacts, including a 17-ton section of the hull that was raised out of the ocean in 1998.
Can you see the Titanic on Google Earth?
Unfortunately it has been removed in all versions. For some reason, it has been taken out and you can no longer find it. You can find the co-ordinates and zoom into the area, but the little 3D model of the titanic is no longer there. The 3D model is still there in Google Earth Pro.
What depth is the Titanic?
The ship, which fell to the seabed in two parts, can now be found 370 miles off the coast of Newfoundland at a depth of roughly 12,600 feet. Fields of debris surround each part of the wreck, including some of the ship’s bunkers, passengers’ luggage, wine bottles and even the intact face of a child’s porcelain doll.
What is the longest breath held?
In aquatic mammals, this reflex is particularly well-developed. Without training, we can manage about 90 seconds underwater before needing to take a breath. But on 28 February 2016, Spain’s Aleix Segura Vendrell achieved the world record for breath-holding, with a time of 24 minutes.
How deep can a whale dive?
The deepest recorded dive was 2,992 metres, breaking the record for diving mammals. Experts have suggested that this dive was unusually deep for this species. A more normal depth would be 2,000 metres. Sperm whales also regularly dive 1,000 to 2,000 metres deep.
Does the ocean end?
While this question appears to have a simple answer, the reality is that all the world’s waterways are connected to each other. There are no borders within the water itself, rather the names were human constructs given to different oceans in regard to around which bodies of land they flow.
How cold is the bottom of ocean?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F).
Are oceans getting deeper?
The Atlantic Ocean crushes that depth, however, deepening in(?) at a whopping 27,000 feet deep. For reference, that’s approximately as deep as Mount Everest is tall. The deepest floor of any ocean on Earth, however, is the Mariana Trench, which is in the western Pacific Ocean.
What happens to torpedoes that miss?
Even if they do miss, they also come with self-destruct mechanisms too. For older torpedoes, if the water depth is great enough, the water pressure should be sufficient to effectively crush the torpedo casing, destroy its firing mechanism or even trigger an explosion in relative safety.
How deep can a submarine launch a torpedo?
|Mark 48 torpedo|
|Maximum depth||500 fathoms, 800 m (2,600 ft) (estimated), officially “greater than 1,200 ft”|
|Maximum speed||55 kn (63 mph; 102 km/h) (estimated) officially “greater than 28 kn (52 km/h; 32 mph)”|
|Guidance system||Common Broadband Advanced Sonar System|
Can a submarine take a torpedo hit?
It is possible for the firing platform—the submarine that fired the torpedo—to enter the kill box during a torpedo attack. If not shut down, the torpedo would consider it a valid target. Situational awareness is key during a torpedo attack to prevent this.
How long can a submarine stay underwater?
Diesel-electric submarines may remain immersed for up to 48 hours without recharging their batteries, but they should surface to operate a generator. Nuclear-powered submarines in the army may remain submerged for extended periods of time.
How do modern submarines get oxygen?
Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.
How many of the lost 52 submarines have been found?
Taylor has discovered seven submarine wrecks since 2010, five of which were lost during WWII.
Why can’t submarines have windows?
Typically, submarines don’t have windows and hence the crew cannot see outside. When a submarine is near the surface, it uses a periscope for a view of the outside. Most submarines travel much deeper than periscope depth and navigation is done with the help of computers.
How many submarines were lost in WWII?
Fifty-two submarines of the United States Navy were lost during World War II.
