Did anyone survive on the Kursk?
A note that was found on one of four bodies raised from the sunken Russian nuclear submarine Kursk, revealed today that at least 23 people remained alive after powerful explosions killed most of the crew..
How deep can a submarine go before being crushed?
What the Navy can tell you is that their submarines can submerge deeper than 800 feet. But they don’t go as deep as the research subs that explore the seafloor.
What happens if a submarine gets hit?
Upon exploding, a successful torpedo hit causes a hull breach in the submarine – that means one or more of its compartments will start flooding with water. … If the explosion manages to cause water to enter a sufficiently large number of compartments that the submarine’s buoyancy is hindered, it will sink.
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 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.
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.
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.
Do submarines run out of air?
A sub is actually far more self sustaining than the space station – due to the nature of water availability. The ISS WILL run out of air (oxygen) if it’s not periodically replenished, either as oxygen, or as water to make it from. As long as the reactor is running, a nuclear-powered submarine will NEVER run out of air.
Are submarines safe from 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 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.
Was the USS Thresher ever found?
On April 9, 1963, the Thresher was 220 miles east of Cape Cod, conducting diving tests. … But Thresher never surfaced, and the Navy later found the sub in six pieces on the bottom of the Atlantic Ocean. All 129 personnel on board were killed.
How do submarines get air?
Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of “oxygen canister” that releases oxygen by a very hot chemical reaction. … The carbon dioxide is trapped in the soda lime by a chemical reaction and removed from the air.
At what depth will water crush you?
At about 10–12 meters (33–40 feet) of depth, pressure of water column above you (1 extra atmosphere of pressure per 10 meters) will compress air spaces in your body by half, with lungs compressing the most by the absolute volume.
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.
Can a submarine break through ice?
Typical submarines can break through about three feet of ice. Vessels that have been specifically strengthened can go through about nine feet.
Is smoking allowed on Navy ships?
The policy banned the use of tobacco during basic training, increased the number of designated nonsmoking areas, and prohibited health care providers from smoking on duty. … In 1993, the USS Theodore Roosevelt (CVN-71) became the first smoke-free Navy ship.
How long can a Trident submarine stay submerged?
The nuclear submarine that can remain underwater for 25 years.
