How fast did ww2 submarines go?

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

On the surface, powered by four diesel engines, the Balao had a top speed just over 20 knots (37 km/hr); cruising at 10 knots (18 km/hr) her range was 11,000 nautical miles (20,000 km).

What was the fastest ww2 submarine?

The I-201 class were of advanced design, and had been built for high underwater speed. They were the fastest operational submarines built during World War II, surpassing even the German Type XXI submarines.

How fast were ww2 German submarines?

The submarine had a maximum surface speed of 17.7 knots (32.8 km/h; 20.4 mph) and a maximum submerged speed of 7.6 knots (14.1 km/h; 8.7 mph).

How deep did submarines go in ww2?

World War II German U-boats generally had collapse depths in the range of 200 to 280 metres (660 to 920 feet). Modern nuclear attack submarines like the American Seawolf class are estimated to have a test depth of 490 m (1,600 ft), which would imply (see above) a collapse depth of 730 m (2,400 ft).

How fast could a WWI submarine go?

Since World War I, nautical technology has evolved at a rapid rate, but in 1914 U-boats were considered quite advanced. These vessels could reach maximum depths of 50 meters or 165 feet, achieve speeds of 16 knots at the surface and eight knots underwater, and had a range of up to 25,000 miles.

The Supersonic Submarine - New Secret US Army Development?

How many submariners died in ww2?

During World War II, the U.S. Navy's submarine service suffered the highest casualty percentage of all the American armed forces, losing one in five submariners. Some 16,000 submariners served during the war, of whom 375 officers and 3,131 enlisted men were killed.

How long would a German U-boat stay at sea?

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.

What did ww2 submariners eat?

Meat, vegetables (mainly potatoes), bread and fruits were the basic ingredients in the submariners' menu on German U-Boats during World War 2. While long-distance German U-Boats were excellent killing machines, habitability ranked very low on their designers' priority list.

How much fuel did a ww2 submarine carry?

“This boat has the ability to store up to 110,000 gallons of raw dirty bunker fuel for all five of the diesels.” One such submarine with the reliable power plant engine was the USS Pampanito (SS-383), a World War II Balao class Fleet submarine built from 1942 to 1944.

Does it stink in a submarine?

You are probably wondering why I would call this post such thing... Since Submarines remain submerged with a sealed atmosphere they rely on a chemical called Amine to remove the carbon dioxide. This chemical makes everything stink.

How fast did ww2 destroyers go?

Though the ships were large, exceeding 430′ (132m) in length, they carried a correspondingly large powerplant. The destroyers could produce up to 81,000shp, enough to propel the ships to speeds of 45 knots. This not only made them the fastest destroyers of World War II, but the fastest destroyers of all time!

How fast did ww2 torpedoes travel?

"The torpedoes used in World War II were usually 20 to 24 ft (6.1–7.3 m) long, carrying up to 600 lb (272 kg) of explosives at a speed of 50 knots for more than 10,000 yd (9,144 m)." Torpedoes.

Do submarines travel faster underwater?

Why Can a Submarine Go Faster Underwater than on the Surface? Surface Tension: The shape of the tear drop hull design allows a submarine to slice cleanly through the ocean when there is water on all sides - as well as house sensitive sonar equipment.

Who had the best submarine in ww2?

The best record of any US submarine

Commissioned in 1943, USS Tang was a Balao-class diesel-electric submarine with a crew of 87 and an arsenal of 24 torpedoes. Its commanding officer, Lt. Cmdr. Richard O'Kane, had served on five war patrols as the executive officer of the highly successful USS Wahoo.

How good were Japanese submarines in ww2?

By 1945, Japan had built all 39 of the world's diesel-electric submarines with more than 10,000 horsepower, and all 57 of the world's diesel-electric submarines capable of 23+ knots surface speed. The Japanese navy also built submarines with the fastest underwater speeds of any nation's combat submarines.

Did the Japanese have good submarines in ww2?

Imperial Japanese Navy submarines originated with the purchase of five Holland type submarines from the United States in 1904. Japanese submarine forces progressively built up strength and expertise, becoming by the beginning of World War II one of the world's most varied and powerful submarine fleets.

Did ww2 submarines have showers?

Making fresh water from sea water meant running it through a condenser situated in the lower flat of the engine room. This process used up electricity that was being generated by an auxillary engine, which needed precious fuel to operate. As a result, we only had one shower a week.

Are there cockroaches on submarines?

In the heaviest of infestations – on Navy submarines and in children's bedrooms alike – they will gnaw off their sleeping victims' eyelashes. But those physical and behavioural traits do not explain why roaches are so frequently the subjects of phobias.

How did WWII submarines recharge their batteries?

Submarines need large amounts of electricity to operate safely under water. They charge their batteries using diesel or nuclear-driven generators.

Did ww2 submarines smoke?

Smoking was allowed but only when the submarine was at the surface never when it was submerged.

Why did submariners eat lemons?

His reported experiment on board a naval ship in 1747 showed that oranges and lemons were a cure for scurvy.

How many U-boats are still missing?

A U-boat of this type, listed for decades as being sunk off Gibraltar, was found on the sea bottom about 60 miles off the coast of New Jersey in 1991. According to the definitive website Uboat.org, a total of 50 German U-boats remained unaccounted for after the end of World War II.

Did U-boats have to surface?

While U-boats were faster on the surface than submerged, the opposite is generally true of modern submarines. The most common U-boat attack during the early years of the war was conducted on the surface and at night.

How long did ww2 submarine batteries last?

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. Before sonar became dependable, most submarine combat took place during the day, for the advantage of sunlight (depending on depths).

Who sank the most U-boats in ww2?

Of the U-boats, 519 were sunk by British, Canadian, or other allied forces, while 175 were destroyed by American forces; 15 were destroyed by the Soviets and 73 were scuttled by their crews before the end of the war for various reasons.
