What is the fastest US submarine?
USS SeawolfThe fastest U.S.
submarine, the USS Seawolf (SSN-21), is believed to reach up to 35 knots.
Electric boat is reportedly working on an underwater craft capable of transporting Navy Seals at speeds up to 100 knots (185 kph / 115 mph) using supercavitation..
What is the world’s largest torpedo?
Here’s what we can say: At more than six feet in diameter and 65 feet long, weighing perhaps a hundred tons, Poseidon is the largest torpedo ever developed, coming in at thirty times the size of a heavy torpedo. In fact, the torpedo is so big it can be carried only by specially modified submarines.
How deep can a depth charge go?
New hydrostatic pistols increased the maximum detonation depth to 900 ft (270 m). The Mark VII’s 290 lb (130 kg) amatol charge was estimated to be capable of splitting a 7⁄8 inch (22 mm) submarine pressure hull at a distance of 20 ft (6.1 m), and forcing the submarine to surface at twice that.
How fast can a torpedo go underwater?
The British Spearfish torpedo designed to counter high-speed Russian submarines, such as the Alfa-class submarine, is reputed to have a speed in excess of 70 knots (130 km/h). The Russian rocket-powered supercavitating torpedo VA-111 Shkval is reportedly capable of speed in excess of 200 knots (370 km/h).
Are subs faster underwater?
Yes, as Larry has succinctly pointed out with a neat cross reference, the modern submarine travels faster underwater than on the surface. … Therefore the early submarines were generally much faster when travelling on the surface of the sea than when submerged.
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. … Mark Jones of the Commander Naval Submarine Forces out of Norfolk, Va., said about 40 percent of the submarine sailors are smokers.
How far can a torpedo go?
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).
How powerful is a torpedo?
The torpedo is propelled by an advanced pump jet engine and can engage targets within the range of over 40km, at a maximum speed of 40kt.
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.
