Cars, bikes, and everything fast are his passion, and he writes about them on many sites. Unlike my other fastest in the world articles, this specific one is a bit tricky, especially if you understand the dynamics of a submarine.
So, what are we talking about? Military submarines, as a concept, need to be silent underwater so that they could sneak up on an enemy or run away from an enemy without being detected. Now speed underwater does the opposite of silent, it makes the submarine noisy and hence easy to detect.
So, why would we want to have fast submarines, if being slow serves the purpose? The answer is simple. You see, in a war-like scenario, it does not make sense to be extra silent and not reach the spot where the submarine is needed the most, in good time.
Or for that matter, when a torpedo is fired at a sub, it should be capable of outrunning it or outsmarting it; the latter approach is the launching of flares or its equivalent obstructing the approaching missiles. Considering the points mentioned in favor of fast attack submarines, it is, therefore, possible that we do have fast ones around.
In this list, we will also include futuristic submarines along with the current and past ones, with the usual caveat of including only the information available in the public domain.
The water drag reduction due to the supercavitation of vapour bubbles around the sub. Water therefore does not cause drag on the sub and it can move at supersonic speed. China has a penchant to bring in the fastest of its kind in various spheres of operation and submarines are the newest area.
It is worthwhile to note that it already holds the record for the fastest trains in the world. You can read about the fastest trains in the world here. China will rely on the concept of supercavitation to build the fastest submarine that the world has ever seen. Supercavitation, itself, is not a new concept. The Russians were the first to build missiles using the concept which allowed the missiles to move at breathtaking speeds in the water towards enemy craft ship or submarine.
The idea behind supercavitation is to build air bubbles around the moving missile, thereby, reducing the water drag and allowing the missile to reach speeds comparable with missiles flying in the air. China intends to use the same concept in building the next generation submarines. What will amaze you is the numbers that are estimated. Take a look. What makes this unreal is that the second submarine in the list has a top speed of 82 kmph.
See the difference? Or for that matter, the fastest military aircraft did a 7, kmph flight. This may be true. The fastest submarine is claimed to be the Soviet K, launched in , with a top speed of K was laid down on 28 December and commissioned on 31 December , at Severodvinsk.
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. You might be interested: Quick Answer: How can i measure distance on google maps? Columbia-class Ballistic Missile Submarine. Project Borei-class Ballistic Missile Submarine. 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. Type : Diesel electric attack submarine Speed : And now with number four we have the Vanguard class.
The vanguard class currently serving with the royal navy. This is a nuclear-powered ballistic missile submarine. A new pressurized water reactor the rolls-royce pwr2 was designed for the vanguard class. The reactor drives two gec steam turbines linked to a single shaft pump jet propulsor giving the submarine a maximum submerged speed of over 25 knots. They are the largest submarines manufactured in the uk displacing tons when submerged.
This submarine is rated for a test depth of meters. Up next at number 3 is the sierra class which is a nuclear-powered attack submarine intended for the soviet navy and currently in service with the Russian navy. The particular submarine class is unique for its design. Its light weight and made with strong titanium pressure hull. This design enables the submarines to dive to more depths reduce the level of radiated noise and increase resistance to torpedo attacks.
It is powered by a single ok pressurized water reactor and the sierra class has a test depth of about meters. According to u. This submarine class capable of hiding submerged for long periods of time in difficult to access shallow littorals. It has a test depth of meters. The number one Deepest Diving Submarines in our list is none other than the Oscar class. The Oscar class is the deepest diving operational submarine in the world today.
It is a nuclear powered cruise missile submarine designed in the Soviet Union for the soviet navy.
