How long can submarines stay under?
three monthsThe 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.
The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged..
Do submarines kill whales?
Unfortunately for many whales, dolphins and other marine life, the use of underwater sonar (short for sound navigation and ranging) can lead to injury and even death. … These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source.
Which country has the most advanced submarine?
Currently top 10 attack submarines in the world are these:Nr.1 Seawolf class (USA) … Nr.2 Virginia class (USA) … Nr.3 Astute class (United Kingdom) … Nr.4 Graney class (Russia) … Nr.5 Sierra II class (Russia) … Nr.6 Improved Los Angeles class (USA) … Nr.7 Akula class (Russia) … Nr.8 Soryu class (Japan)More items…
Can sperm whale sound kill?
Sperm Whales Are So Loud They Could Potentially “Vibrate” You to Death. Sperm whales are so loud that their clicks are capable of killing a human within their vicinity, says one science and adventure journalist. … Sperm whales are the loudest mammals on the planet, with vocalizations reaching an astonishing 230 decibels.
Can a submarine ping kill you?
At 200 Db, the vibrations can rupture your lungs, and above 210 Db, the lethal noise can bore straight through your brain until it hemorrhages that delicate tissue. If you’re not deaf after this devastating sonar blast, you’re dead.
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.
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.
Why do submarines look like whales?
Most subs have two types of sonar: active and passive. Active sonar sends out acoustic sounds, or “pings,” which can reach thousands of yards. If the ping bounces back, that means it hit an object—like a whale, a ship, or another submarine.
Has anyone survived a submarine sinking?
All of the 72 crew made it to the surface but only 15 survived with the rest swept out to sea by the tide and lost. … Of the Soviet submarine’s 69 crew, 34 of those who made the ascent to the surface later died from hypothermia, heart failure or drowning.
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 would happen if a submarine went too deep?
What they found was that if they built the submarine in the wrong shape, it would collapse when it went too deep underwater. The reason for that is because the deeper you go underwater, the more water pressure there is. … At the ends of the sub, they build it in the shape of a hemisphere.
Has a submarine ever sunk another submarine?
The German submarine U-864 was a Type IXD2 U-boat of Nazi Germany’s Kriegsmarine in World War II. … It is the only documented instance in the history of naval warfare where one submarine intentionally sank another while both were submerged.
