What does a submarine do?

Asked by: Jennifer Jimenez

Militaries use submarines to patrol ocean waters and to attack enemy ships during wartime. Military submarines are usually very large. They may carry more than 100 people. They also carry such weapons as missiles and torpedoes.

What does a submarine do underwater?

A regular boat cannot control or change its buoyancy, but a submarine can. This allows a submarine to dive under the water or to come up to the surface. To control its buoyancy, the submarine has ballast tanks (see picture) that can be filled with water or filled with air.

What does a submarine do in the Navy?

LIFE AS A SUBMARINER

Our agile and adaptable Attack Submarines provide covert surveillance that keeps the seas safe for all, while Vanguard-class vessels carry the ballistic missile that are our nation’s nuclear deterrent. Submariners are some of the Royal Navy’s most exceptional personnel.

How long can a submarine stay underwater?

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. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged.

What do submarines do with poop?

So, what we do is all the poop and all the excrement and all that stuff goes into the sanitary tanks. There’s three sanitary tanks onboard a submarine. So what you have to do to discharge it is you have to pressurize a sanitary pump that blows the sanitary waste outside of the boat.

How do submarines not run out of air?

Oxygen is supplied either from pressurized tanks, an oxygen generator (which can form oxygen from the electrolysis of water) or some sort of “oxygen canister” that releases oxygen by a very hot chemical reaction.

Are submarines safe?

The underwater environment is a dangerous one. Submarines face many perils of the deep. Even a small fire or gas leak inside a submerged submarine can have catastrophic consequences. A collision with another vessel or grounding may be much more serious for a submarine than for a surface ship.

How is life in a submarine?

Life Is Divided Into Three Six-Hour Segments

Forget living a normal life while on a submarine, you live and die on a strict schedule. The hardest thing might be adjusting to the three, six-hour segment routine you have to endure. Crew members get six hours for sleeping, six hours on watch, and six hours for free time.

Do submarines get attacked?

They support ground troops with cruise missiles, engage enemy naval ships and submarines using torpedoes, and sometimes transport commandos who need to sneak ashore. The deployment of attack submarines during peacetime sends a reminder to competing navies that they do not have free rein over international waters.

Do submarines have showers?

The showers on a submarine are set up much like the ones in your home, well kind of. They have hot and cold water access with a recirculation pump so that the water stays hot so that you can use it quickly and efficiently by minimising water usage. Reducing water usage is a constant major driver for submariners.

Do submarines have WIFI?

To connect with terrestrial technologies, the nodes communicate with gateway buoys on the water’s surface, linking to the above-sea internet via cellular networks or satellites. Still, undersea broadband is a way off, due to the low data rates.

What do submarines smell like?

Some submarines smell like Cinnabon.

The cooks on board the submarines are specifically trained, and they’re really, really good. There’s nothing better in the world than the smell of hot sticky buns going through the submarine at midnight.

What is submarine pay?

Submarine Duty Incentive pay is a monthly taxable pay for sailors attached to submarine staffs. They can get Submarine Duty Incentive Pay: While attached to a submarine crew; While serving as an operator or crewmember of an operational submersible (including an undersea exploration or research vehicle);

How does a submarine navigate underwater?

Submarines carry an inertial navigation system (INS), which measures the boat’s motion and constantly updates position. Because it does not rely on radio signals or celestial sightings, it allows the submarine to navigate while remaining hidden under the surface.

How do submarines sink and float?

In submarines, this is controlled by ballast tanks. When the tanks are empty, the submarine has less mass and it floats like a normal ship. As water is allowed into the tanks, the mass of the submarine increases, the downward gravitational force on the submarine increases and the submarine begins to sink.

Does a submarine swim?

To answer zenyatta on this, no, a submarine does not swim. A sub moves through the water by propulsion not of the body but of an engine. Therefore as a sub does not have any moving parts, it does not swim.

How do submarines make oxygen?

Oxygen in submarines is produced by putting sea water through a process of electrolysis. Submarines typically have a couple of big oxygen tanks as well, used to quickly raise oxygen concentration if the system fails.

Do submarines have WiFi?

To connect with terrestrial technologies, the nodes communicate with gateway buoys on the water’s surface, linking to the above-sea internet via cellular networks or satellites. Still, undersea broadband is a way off, due to the low data rates.

Are submarines hot inside?

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.

How do submarines get fresh water?

Since submarines don’t have access to municipal water systems or wells, they have to find a way to maintain a fresh water supply for drinking. Most ships have special equipment that can remove the salts from seawater to turn it into fresh drinking water. This process is called distillation.

Can submarines sit on the ocean floor?

And so yes, it is possible for a submarine to reach the bottom of the sea. However, nuclear submarines would pretty much never do that and diesel-electric submarines are quite rare nowadays.

Do submarines fly?

Submarines are heavyweights with massive hulls strong enough to resist crushing forces from the surrounding water. Aircraft use lift from their wings to stay aloft, while submarines operate like underwater balloons, adjusting their buoyancy to sink or rise.

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.

Why can’t females be deployed on a submarine?

Can women go on submarines? Women are not currently assigned to submarine crews because of the very limited habitability and privacy onboard a submarine.

What happens if someone dies in a submarine?

If the submarine is in operation, they can be on board for a couple of days to several weeks, it really does depend on the situation. In a nutshell, when someone dies on board, it can become a crime scene where nothing can be touched if they are in operation and then it’s time to prioritise food.

Where do they sleep on a submarine?

Most of the crew sleep in “racks” of three bunk beds that are hardly ever unoccupied. They call it “hot racking,” where men on different shifts rotate through their precious sleep time. Looking towards the mess on the USS California. But this submarine looks almost exactly the way subs do in the movies.

Is alcohol allowed on submarines?

“The use or introduction for drinking purposes of alcoholic liquors on board any naval vessel, or within any navy yard or station, is strictly prohibited, and commanding officers will be held directly responsible for the enforcement of this order,” reads the hundred year-old order.

How many bathrooms does a submarine have?

Other concerns range from bathrooms and bunks to potential pregnancies. Aboard fast-attack submarines, two bathrooms – each with four toilets and two urinals – serve 100 crew members. Crew chiefs and officers use another three baths.

What do submarines smell like?

The cooks on board the submarines are specifically trained, and they’re really, really good. There’s nothing better in the world than the smell of hot sticky buns going through the submarine at midnight.

Is there a doctor on a submarine?

Normally, a doctor is not onboard a submarine. A senior corpsman who has received special training including emergency surgical techniques is the one in charge of handling any issue. For the most part, this includes dealing with the flu or minor stitches.
