Looking at their specifications they all have 2 diesels, not 4. So with 2 diesels dedicated to charging, they put 900 kW into the batteries. 10 minutes gives 9000 kW. min or 150 kWh, enough to run one motor at 1/4 load for an hour.
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. Diesel subs must surface to recycle their batteries because carbon monoxide fumes are deadly.
How long can a submarine run on batteries?
Improvements in the design of conventional lead-acid batteries have somewhat increased endurance at low speed. Many modern submarines, for example, can remain submerged (at about three knots) for as long as a week to 10 days.
What type of batteries did ww2 submarines use?
Since World War II, submarines have used lead acid batteries. Lead acid batteries are heavy, but they’re also a proven technology. They’re also obsolete in the consumer world, replaced in the 1990s by nickel metal hydride batteries.
Did ww2 submarines have air conditioning?
Generally speaking, they had to come to the surface to condition the air or use a snorkel. Most countries in the world did not have dedicated HVAC systems capable of conditioning the air while submerged or hatches closed, and the above measures didn’t resolve the issues with the crew’s health and morale.
How long can nuclear submarines stay underwater?
Nuclear submarines can operate underwater for three to four months at a time and easily span seas. While few conventional submarines can travel the distance, none have the same depth of endurance below.
How many miles can 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.
Can a submarine make its own oxygen?
How does the crew get breathable air inside a submarine? Oxygen onboard a submarine is released either through compressed tanks, an oxygen generator, or by some form of an ‘oxygen canister’ that works by electrolysis.
How long does oxygen last in a submarine?
Air isn’t a problem as their make their own oxygen and keep the air clean. The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater.
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.
How long can a nuclear ship go without refueling?
about twenty years
Nuclear power allowed submarines to run for about twenty years without needing to refuel. Food supplies became the only limit on a nuclear submarine’s time at sea. Since then, similar technologies have been developed to power aircraft carriers.
How thick is a submarine hull?
2 to 4 millimeters thick
The external hull, which actually forms the shape of submarine, is called the outer hull, casing or light hull. This term is especially appropriate for Russian submarine construction, where the light hull is usually made of steel that is only 2 to 4 millimeters thick, as it has the same pressure on both sides.
What is crush depth for a submarine?
What is crush depth? The name is foreboding and fairly self-explanatory; it’s when the submarine goes so deep the water pressure crushes it, causing an implosion. The crush depth of most submarines is classified, but it’s likely to be more than 400 metres.
How many submarines are in the ocean right now?
With around 71 submarines in active service the US Navy has the biggest fleet in the world. Next-generation submarines are gradually being rolled out to replace the ageing Los Angeles-class fleet and their mission has been extended in response to new undersea challenges.
Is it cold on a submarine?
Even though the entire submarine has air cooling facility, only two decks are air-conditioned. The temperature in the rest of the submarine is around 30-35 degrees and the crew works in sweltering heat. The quality of the air is monitored constantly for impurities.
Where do submarines get air to surface?
To get a submarine to surface, the main vents in the top of the tank are closed and high-pressure compressed air is blown into the ballast tanks, forcing the water out through the flood ports at the bottom of the tank. Replacing ballast water with lighter air reduces the vessel’s total mass.
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. It will take effect by Dec. 31, 2010.
Why can’t females be deployed on a submarine?
Britain, Canada and the U.S. Navy do not put women on submarines primarily because of these irresolvable health risks and operational complications. In addition, habitability standards on subs are well below minimum standards on surface ships.
What do submarines do with human waste?
Originally Answered: How do submarines get rid of human waste? Human waste and other waste water drain into holding tanks. Periodically all input to the tanks are shut via valves, valves are opened to the ocean and compressed air is introduced to the tanks to force all contents into the sea.
Is alcohol allowed on a submarine?
“Although alcohol is available on board Royal Navy ships and submarines, its consumption is extremely limited and the RN’s promotion of healthy living, coupled with the professionalism of modern sailors, means that fewer sailors drink at sea than ever before,” he added.
Has a submarine ever hit a whale?
British Navy mistook whales for submarines and torpedoed them, killing three, during Falklands War. THE British navy killed three whales with torpedoes after mistaking them for enemy submarines. THE British navy killed three whales after mistaking them for enemy submarines during the Falklands War, it has been revealed …
How many sailors can fit in a submarine?
Fast Attack submarines have a crew of around 134, broken into about 120 enlisted and 14 officers, while SSBNs have an additional 16 enlisted and usually an additional officer.
What class of submarine is Vigil?
The 2021 BBC TV series Vigil is set on board a fictional Vanguard-class submarine named HMS Vigil. Further boats of the class named HMS Virtue, HMS Vanquish and HMS Vanguard are mentioned.
Was vigil filmed in a real submarine?
While some locals may recognise these areas of the show, the majority of the filming actually took place on a set created to look like a Trident submarine. Lead director, James Strong, spoke about the challenges of filming in such an environment recently.
Is vigil set on a real submarine?
Vigil is set at a fictional nuclear Submarine base, and on board the fictional HMS Vigil, a Royal Navy nuclear submarine. The peace camp in Vigil is inspired by the real-life Faslane peace camp, which is located next to Faslane Naval base in Scotland – the home of the Trident nuclear programme.
Was Vigil a real submarine?
HMS Vigil is not a real ship. Vigil is a fictional Vanguard-class submarine of the Royal Navy. The Vanguard class is a class of nuclear-powered ballistic missile submarines currently in service with the Royal Navy. They form part of the Trident nuclear programme.
Did a submarine sink a trawler?
In November 1990 the pelagic trawler Antares sank in the Firth of Clyde with all four crew members on board all losing their lives. The loss of the vessel was immensely controversial as it emerged that the Antares was sunk when its nets became tangled with a Royal Navy nuclear submarine that passed underneath.
Is Vigil a true story?
A spokesperson for the BBC has confirmed to The National Scot that the show is indeed fictional, saying that it is “a fictional drama and is not inspired by or based on any specific real-life events”. However, there are several parallels to real-life events throughout the series.

A camera shows the submarine disappearing. Under the water surface are they eventually descending four hundred five hundred more than six hundred feet beneath the surface of the sea.
Is it hot inside a submarine?
Modern submarines are mostly cool, that is in the fwd compartments where much of the navigational and sensor equipment is sited. This equipment needs to be kept cool. Back Aft in the engine room and after compartments can be very hot as there is a lot of machinery running.
What is the food like on a submarine?
Fresh food lasts about two weeks, then it is canned, dried, and frozen food for the rest of the patrol. When a submarine leaves on patrol, food fills every available corner. Eating takes place in the crew’s mess. Despite the tight galley space, good meals are the rule, with the same menu for officers and enlisted men.
How far can a submarine travel without Refuelling?
The steam then powers a giant turbine which turns the sub’s propeller. Those small nuclear power plants on submarines could supply the necessary power for these boats to travel up to 500,000 miles and to stay underwater almost indefinitely without refueling.
How do submarines get air?
First, oxygen must be pumped into the vessel as the crew uses it up by breathing. Oxygen is typically supplied to the submarine from pressurized tanks. A computerized system monitors oxygen in the air and releases fresh oxygen as its needed by the crew.
