How fast is the fastest submarine?

44.7 knots
The boat was at one point the world’s fastest submarine, reaching a record submerged speed of 44.7 knots (82.8 km/h; 51.4 mph) on trials.

How fast can a Navy sub go?

The United States Navy has contracted with the General Dynamics Electric Boat Division to support development of the Underwater Express, an undersea transport capable of controllable speeds up to 100 knots (185 km/h) through supercavitation.

How fast can a submarine go around the world?

There have been reports that these boats can actually get up to around 35 miles per hour underwater. The latest American Virginia-class attack submarines have a publicly stated top submerged speed of around 29 miles per hour, but this is still significantly slower than the Project 661 design.

Is a submarine faster underwater?

Yes, as Larry has succinctly pointed out with a neat cross reference, the modern submarine travels faster underwater than on the surface. The use of a single mode of propulsion and a hull form optimised for underwater travel has brought this about.

How fast can a submarine 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.

Can submarines travel faster than ships?

Nuclear power allows submarines to go faster than surface ships. (This may be true.) The fastest submarine is claimed to be the Soviet K-162, launched in 1969, with a top speed of 44.7 knots (82.8 km/hr). Nuclear powered aircraft carriers have disclosed top speeds around 33 knots.

How fast can a ww2 submarine dive?

Model of the USS Balao (SS-285) Fleet Submarine

Two 126-cell battery groups gave her a submerged top speed of 8.75 knots (16.2 km/hr); holding her speed to 2 knots (4 km/hr), she could remain submerged for 48 hours.

How deep can Navy submarines 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. The average depth of the world’s oceans is 3,790 meters, or 12,400 feet, or 2 1⁄3 miles.

What is the fastest underwater vehicle?

The Russian rocket-powered supercavitating torpedo VA-111 Shkval is reportedly capable of speed in excess of 200 knots (370 km/h). German press reports of an underwater anti-torpedo missile named Barracuda that allegedly reaches 430 knots (800 km/h).

How long does it take for a submarine to sink?

That typically takes 10-15 minutes, depending on how many and what systems need to be checked. Then the sub proceeds on its previously assigned mission. Total time from surface to test depth will be 30-45 minutes when done routinely.

Do submarines tilt?

The planes can be tilted to change the lift force, so making the submarine climb or dive through the sea, as necessary. The planes provide most of the submarine’s control of its depth, most of the time.

How long could German U-boats stay submerged?

The Germans’ most formidable naval weapon was the U-boat, a submarine far more sophisticated than those built by other nations at the time. The typical U-boat was 214 feet long, carried 35 men and 12 torpedoes, and could travel underwater for two hours at a time.

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.

Where do submarines get air to surface?

To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. Replacing ballast water with lighter air reduces the vessel’s total mass.

Do submarines have Internet?

No. Though email is used. May and or may not be sent very quickly depending on operational requirements. Can 2 submarines be close to each other without knowing it?

Is it cold on 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 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 it hot on a submarine?

Modern submarines are mostly cool, that is in the fwd compartments where much of the navigational and sensor equipment is sited. This equipment needs to be kept cool. Back Aft in the engine room and after compartments can be very hot as there is a lot of machinery running.

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.

Why does it get hot in a submarine?

the submarine is warmer than the ocean water, the interior heat of the vessel gradually passes through the shell into the water. The temperature of the air inside drops and, when it reaches the dewpoint, the water vapor in the air begins to condense on every available surface.

Can you drink on a submarine?

“Although alcohol is available on board Royal Navy ships and submarines, its consumption is extremely limited and the RN’s promotion of healthy living, coupled with the professionalism of modern sailors, means that fewer sailors drink at sea than ever before,” he added.

How do submarines dispose of human waste?

Originally Answered: How do submarines get rid of human waste? Human waste and other waste water drain into holding tanks. Periodically all input to the tanks are shut via valves, valves are opened to the ocean and compressed air is introduced to the tanks to force all contents into the sea.
