Quick Answer: How Fast Can A Torpedo Go Underwater?

How fast is the fastest torpedo?

The fastest known NATO torpedo is the Spearfish (UK) at 75 knots (138 kph / 86 mph), however the German Navy is reportedly developing a supercavitating torpedo, the Barracuda, that is faster than the Russian Shkval..

What is the fastest underwater vehicle?

The fastest airplane to ever take flight was the SR-71 spy plane, which was capable of traveling over 2,000 mph. The fastest-ever car was Thrust SSC, which holds the land-speed record of 760 mph. And the fastest submarine was the 51 mph Soviet K-222 nuclear attack sub.

Is a submarine faster underwater on surface?

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.

What is the longest a submarine has stayed submerged?

The longest submerged and unsupported patrol made public is 111 days (57,085 km 30,804 nautical miles) by HM Submarine Warspite (Cdr J. G. F. Cooke RN) in the South Atlantic from 25 November 1982 to 15 March 1983.

What is crush depth for a human?

Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.

What is the fastest warship?

With a maximum speed of 60 knots (110 km/h), the Skjold-class corvettes were the fastest combat ships afloat at the time of their introduction….Skjold-class corvette.Class overviewLength:47.50 m (155.8 ft) 44.3 m (145 ft) (Length on cushion)Beam:13.5 m (44 ft)Draught:1.0 m (3.3 ft)18 more rows

Are submarines safe from tsunami?

Submarines are relatively unaffected by weather or tsunamis when submerged in deep open waters. … However if a submarine has to go shallow or to periscope depth then conditions on the surface become a major concern. Large enough waves can cause a submarine to be pulled (sucked) up to the surface.

How fast can a submarine go underwater?

How Fast Can a Submarine Go? This is classified as well. 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.

Are submarines faster than ships?

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).

Can you go supersonic underwater?

These are all slower than the speed of sound (pressure waves) underwater, but in a certain sense they are supersonic because they move faster than water is able to flow around them, which (other than the sheer amount of propulsion energy needed) is what makes supersonic flight difficult.

Can you smoke in 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. … Mark Jones of the Commander Naval Submarine Forces out of Norfolk, Va., said about 40 percent of the submarine sailors are smokers.

Why are subs faster underwater?

Frictional and pressure resistance happens for submarines and surface ships. Frictional resistance happens as the water slide past the hull. … So, since submarines for the same speed see less resistance, only frictional and pressure and not wave. So sumarines, for the same power, can go faster underwater.
