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.24-Jul-2019
What is the fastest underwater speed?
- The World Unlimited water speed record is the officially recognised fastest speed achieved by a water-borne vehicle. The current record is 511 km/h (318 mph) – achieved by Australian Ken Warby in the Spirit of Australia in 1978.
What is the top speed of a submarine?
The Russian Alfa-class nuclear-powered submarines had a reported maximum speed of over 40 knots (74 km/h or 46 mph ) and were believed capable of diving to 760 m (2,500 ft).
Who has the fastest submarine?
K-222 was laid down on 28 December 1963 and commissioned on 31 December 1969, at Severodvinsk. It was assigned to the Soviet Red Banner Northern Fleet for the duration of her career. It was the world’s fastest submarine, reaching a record submerged speed of 44.7 knots (82.8 km/h; 51.4 mph) on trials.
Which is faster ship or submarine?
A submarine can be faster than a boat. 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).
What is the speed of a torpedo?
It could travel about 180 metres (200 yd) at an average speed of 6.5 knots (12.0 km/h ). The speed and range of later models was improved by increasing the pressure of the stored air. In 1906 Whitehead built torpedoes that could cover nearly 1,000 metres (1,100 yd) at an average speed of 35 knots (65 km/h ).
Can you smoke on a submarine?
No one can smoke on US submarines because it’s been prohibited since December of 2010.
What is the most dangerous submarine?
The World’s Five Most Dangerous Submarines Here’s What You Need To Remember: None of these submarines has been used in combat. Ohio-class Ballistic Missile Submarine. Columbia-class Ballistic Missile Submarine. Project 955 Borei-class Ballistic Missile Submarine. Recommended: Why an F-22 Raptor Would Crush an F-35 in a ‘Dogfight’
Has a submarine ever hit a whale?
It happens on rare occasions. Whales make sounds that can be heard by the submarine sonar. Submarines usually try to avoid the whales, but on the rare occasions that a collision occurs, it is the whale that suffers the worst of it. The submarines suffer some damage, but it is like your car hitting a medium size …
Does a submarine travel faster underwater?
Yes, as Larry has succinctly pointed out with a neat cross reference, the modern submarine travels faster underwater than on the surface. Since the pre-nuclear subs would therefore be spending most of their time on the surface of the sea, it made sense to give them a shipshape, seaworthy hull form for best speed.
Which country has the best submarines in WW2?
Germany may have built large number of submarines in WW2, creating “wolfpacks” of U-boats, but the US had the best-ever Allied submarines of WW2, the Gato-class and Balao-class submarines. Germany Type XXI so called Electroboat could travel under the sea faster then many Allied convoy escorts.
How do submarines get air?
Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails. Waste CO2 is released into the sea whenever it’s possible.
How deep does a submarine 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.
Why are submarines so slow?
This significantly improved the submerged endurance of the submarine. The problem with this hull form is that it generates a lot of drag on the surface. This is why modern submarines, with their hull form optimized for submerged operation, are slower on the surface.
Can a torpedo sink an aircraft carrier?
During World War II, submarine and aircraft -dropped torpedoes sank hundreds of merchant ships and warships. Unlike the numerous aerial bombs or cannon shells required to sink large warships, just one or two torpedo hits could and sometimes did suffice to sink huge aircraft carriers and battleships.
What is the longest a submarine has stayed submerged?
Originally Answered: What is the longest recorded time that a submarine stayed submerged under water? The longest submerged cruise made public was by the HMS Warspite from November 1982 to march 1983. They stayed under water for 111 days.
