There are established reports and manufacturer’s claims that would indicate two (or perhaps more) submarines are capable of speeds exceeding 30 knots (56 km/h) .
How far can a sub travel?
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 research vessel Atlantis, shown at the surface, is 274 feet long.
How fast can a sub turn?
At a speed of 24 knots , a little more than 27 mph, the submarine makes a fast turn to the right, then to the left while those on board not accustomed to the maneuver hold on. “That was our high-speed turn,” said Cmdr. John Fancher, the commanding officer of the submarine.
Is a sub faster underwater?
A submarine meets more resistance under-water as opposed to on the surface , as on the surface a small fraction of the hull surface is meeting against air resistance instead of water resistance. This does not, however, mean that a submarine travels faster on the surface.
How long can a nuclear ship go without refueling?
Nuclear power allowed submarines to run for about twenty years without needing to refuel. Food supplies became the only limit on a nuclear submarine’s time at sea. Since then, similar technologies have been developed to power aircraft carriers.
Nuclear submarines can operate underwater for three to four months at a time and easily span seas. While few conventional submarines can travel the distance, none have the same depth of endurance below.
Is there WIFI on submarines?
To connect with terrestrial technologies, the nodes communicate with gateway buoys on the water’s surface, linking to the above-sea internet via cellular networks or satellites. Still, undersea broadband is a way off, due to the low data rates .
Has a submarine ever hit a whale?
British Navy mistook whales for submarines and torpedoed them, killing three, during Falklands War . THE British navy killed three whales with torpedoes after mistaking them for enemy submarines. THE British navy killed three whales after mistaking them for enemy submarines during the Falklands War, it has been revealed ...
How often do submarines sink?
It is extremely rare for submarines to sink, Mr Little points out. It last happened in 2000, when the Russian submarine the Kursk sank in the Barents Sea, killing all 118 crew on board.
How long does it take a sub to dive?
In a World War II-era boat, the whole operation could take as little as 30 seconds with a well-trained crew. In contrast, an Ohio-class ballistic-missile submarine may take as long as five minutes to reach periscope depth from the surface.
How fast can a destroyer go?
Modern destroyers displace about 8,000 tons, are capable of speeds of more than 30 knots , and carry crews of about 300.
What depth do submarines operate at?
It’s generally accepted that the maximum depth (depth of implosion or collapse) is about 1.5 or 2 times deeper. The latest open literature says that a US Los Angeles-class test depth is 450m (1,500 ft), suggesting a maximum depth of 675–900m (2,250–3,000 ft) .
Do your ears pop on a submarine?
Helen – No their ears probably don’t pop because in fact, unlike a scuba diver who takes down a tank of air and breathes it at pressure that is equal to the water around them-which becomes very high very quickly as you go down-submarines are pressurised so that inside them they maintain the same pressure as air at the ...
Why are submarines slower on the surface?
You can tell by that wake that it is not cutting through the water very cleanly . This is why modern submarines, with their hull form optimized for submerged operation, are slower on the surface.
Is a submarine more efficient than a boat?
Modern military subs can easily outpace most civilian surface craft or military transport vessels . The top speed of a lot of them is classified, but almost all the modern nuclear attack boats can surpass 30 knots (not ‘quiet’ at that speed, but attainable).
How do submarines get air?
Oxygen is typically supplied to the submarine from pressurized tanks . A computerized system monitors oxygen in the air and releases fresh oxygen as its needed by the crew. Next, exhaled carbon dioxide must be removed or it becomes a toxin.
How far can aircraft carriers go?
| Class overview | Range Unlimited distance; 20–25 years | Complement Ship’s company: 3,532 Air wing: 2,480 | Crew 5,000–5,200 (including airwing) |

What starts a nuclear meltdown?
A meltdown may be caused by a loss of coolant, loss of coolant pressure, or low coolant flow rate or be the result of a criticality excursion in which the reactor is operated at a power level that exceeds its design limits. Alternatively, an external fire may endanger the core, leading to a meltdown.
How long does oxygen last in a submarine?
Air isn’t a problem as their make their own oxygen and keep the air clean. 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.
Can you smoke on 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. It will take effect by Dec. 31, 2010.
How much do submariners get paid?
| Job Title Salary | US Navy Navy Submarine Officer salaries – 1 salaries reported US$82,803/yr | Royal Navy Writer/Submariner salaries – 1 salaries reported £25,862/yr | BAE Systems Submarine Systems Engineer salaries – 1 salaries reported £28,800/yr |

Why can’t females be deployed on a submarine?
Britain, Canada and the U.S. Navy do not put women on submarines primarily because of these irresolvable health risks and operational complications . In addition, habitability standards on subs are well below minimum standards on surface ships.
Is it cold inside a submarine?
Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.
Can you escape a submarine?
There are two options available for the crew of a submerged disabled submarine (DISSUB); escape or rescue . Escape is the process where the DISSUB’s crew leaves the boat and reaches the surface without external assistance; while rescue is undertaken by outside parties who remove the trapped crew from the submarine.
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.
How many soldiers fit in a submarine?
Fast Attack submarines have a crew of around 134, broken into about 120 enlisted and 14 officers , while SSBNs have an additional 16 enlisted and usually an additional officer.
What happens to waste in a submarine?
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 .
