How fast is the fastest submarine underwater?
On December 30, Captain Golubkov Filipovich took K-162 on a test run seeking to push the titanium sub to its limits. After overriding engine safety controls, the missile submarine attained a world record of
44.7 knots (51 miles per hour)
using 97 percent of reactor power while swimming 100 meters under 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.
Does a submarine go faster above or below water?
Which is faster? 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 fast can a submarine cross the Atlantic?
However, U.S. nuclear-powered submarines can go faster than
23 miles per hour
, which is 37 kilometers per hour or 20 knots (nautical miles per hour) underwater.
What is the fastest warship in the world?

How deep can US submarines go?
How deep can US nuclear subs go? 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.
Are nuclear submarines faster than diesel?
Speed is a significant tactical factor, as it determines maneuverability and the ability to quickly change depth with flow over the hydroplanes. Nuclear power provides attack submarines with a sustained submerged speed of more than 30 knots,
considerably greater than any contemporary diesel submarine
.
Can submarines go in reverse?
Submarines were not designed to go backward
. Sternway, as reverse speed was called, could quickly drag the submarine deeper because all the weight in the engine room tended to pull the stern downward.
What is the fastest known submarine?
| Class overview | Speed 44.7 knots (82.8 km/h; 51.4 mph) | Endurance 70 days | Test depth 400 m (1,312 ft 4 in) (estimated) | Complement 82 (25 officers) |

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 many aircraft carriers does the US have?
The United States has
11 aircraft carriers
and 9 “helo” carriers, nearly as many as all other countries combined, followed by Japan and France, each with four. Eleven other nations have at least one carrier, and several more are under construction.
How far can a nuclear aircraft carrier go?
| Class overview | Propulsion 2 × Westinghouse A4W nuclear reactors (HEU 93.5%) 4 × steam turbines 4 × shafts 260,000 shp (194 MW) | Speed 30+ knots (56+ km/h; 35+ mph) | Range Unlimited distance; 20–25 years | Complement Ship’s company: 3,532 Air wing: 2,480 |

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 …
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 long can nuclear submarines stay underwater?
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.
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.
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
.
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.
The Fastest Ship in the U.S. Navy:
Boeing Pegasus-Class Hydrofoils
.
How fast is a US destroyer?
Many destroyers carry submarine-hunting helicopters, and some U.S. destroyers carry cruise missiles, allowing them to attack targets on land. Modern destroyers displace about 8,000 tons, are capable of speeds of
more than 30 knots
, and carry crews of about 300.
How fast is a destroyer mph?
The highest speed attained by a destroyer was 45.25 knots (83.42 km/h or
52 mph
) by the 2,900 tonne (6.4 million lb) French ship Le Terrible in 1935.
Can you survive a submarine sinking?
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.
