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 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.
What is crush depth for a submarine?
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. The crush depth of most submarines is classified, but it’s likely to be more than 400 metres.
How deep can a US military submarine dive?
What the Navy can tell you is that their submarines can submerge deeper than 800 feet.
How deep can a World War II submarine dive?
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).
Can you smoke inside a submarine?

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?
Military submarines have no need or desire for windows. Windows pose a huge safety risk for military that is unacceptable, as glass can’t withstand anywhere near the pressures of the steel alloys used for the same thickness. Civilian and research submarines can and some do have windows.
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.
How deep can a human dive before being crushed?
How Deep Can a Human Dive Before Being Crushed? There is no fixed depth where we can say for sure that a diver will be crushed once they cross a certain depth. Most recreational divers don’t generally go beyond 130 feet, but commercial divers manage to reach depths of 2,000 feet with the help of atmospheric suits.
