On fast attack subs, the food is lowered into the submarine at port by hand, one box of groceries at a time. On ballistic missile submarines, food is lowered through the escape trunk opening by crane in aluminum modules measuring six by six by five feet.
Food for the crew is the bulkiest commodity in a submarine and becomes the limiting factor for patrol duration. 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.
The cooling equipment of submarines consists of two separate systems, one for refrigeration proper, and the other for air-conditioning. The refrigeration plant is described here.
What was food like when deployed on a submarine? Submariners of all nations, past and present, typically get the best food available in the fleet, as well as the best cooks. Since they're cooking for a lot fewer crew than most surface ships have, the quality is always better as well.
The British began storing citrus fruits on board all of its ships. The British Navy gave its sailors limes or lemon juice rations to ward off scurvy – earning them the nickname of "Limeys" among the American sailors who didn't know about or believe in the preventative treatment.
“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.
Most submarines have a distillation apparatus that can take in seawater and produce fresh water. The distillation plant heats the seawater to water vapor, which removes the salts, and then cools the water vapor into a collecting tank of fresh water.
With that being said, your next question may instantly be “How long should I stay in the shower for?” The easy answer is, as long as you want but traditionally should be between 3-5 minutes.
The source explained: "Because it's a working environment everything gets positioned and the body will be lifted and put in the fridge, not in the torpedo tube like on Vigil, photographs are also taken as it's classed as a crime scene.”
In 2010, the Navy successfully implemented a comprehensive smoking ban aboard submarines.
How long and often can one shower for in a submarine? On a US nuclear sub, you take a shower every single day unless the evaporator is secured for a reason. In fact, the Chief of the Boat (COB) will usually demand you take a shower if you smell like sweat.
A submarine "day" lasts 18 hours and is split into three six-hour shifts. So a submariner may work for six hours and train, maintain equipment or sleep for 12 hours. Bunks are generally stacked three high. Space is at a premium in a submarine, and little of it is afforded to each sailor.
Waste that is discharged overboard must either be pumped out against the ambient sea pressure or blown out using pressurized air. Waste materials are collected and periodically discharged.
What is the Longest a Submarine Has Stayed Submerged? The longest a submarine has ever stayed submerged is 111 days.
In submarine installations, the gases of combustion are piped from the exhaust headers to the outside of the submarine through an in board and outboard main engine exhaust valve and muffler. The inboard exhaust valve is inside the pressure hull of the submarine and is hand operated.
In the enclosed atmosphere of the submarine, these pollutants can build up and pose a health risk. Therefore, aerosol cans (such as hair spray, shave cream, spray deodorant) are not authorized to be brought on board.
Any time the submarine sends a signal, it identifies its position, and loses the secrecy that is at the core of the crew's mission. There is only one washer and dryer on board, so clean clothes are a luxury. But submarines are famous for their good food, always topped off with a desert or two, including ice cream.
There are no restrooms on a submarine. Submarines have heads, where there are a few small stainless steel sinks, 1 or 2 very small showers and 2 to 3 toilet bowls.
Although the actual top speed of American naval vessels is a secret, modern submarines travel faster than 30 knots underwater. Submarines are carefully designed to enhance their speed.
The pressure of water in the power plant of a nuclear submarine is more than the atmospheric pressure, so the boiling point temperature of the water reaches above 100∘ C 100 ∘ C .
Most bigger submarines have something called “Trash Disposal Units”, which are exactly what you think you are. Somewhere in the submarine there is a long tube or a shaft, which has a ball valve separating it from the ocean. Crew members have to assemble canisters from pre-punched galvanized, perforated steel sheets.
US submarines carry a small number of firearms for the officers, senior NCOs and the small number of enlisted sailors whose battle station duties including guarding the vessel and/or its weaponry. These are stored in the ship's tiny armory and they are rarely withdrawn (it's a LOT of paperwork if they get used).
Where do people sleep on the submarine? The submarine is divided into rooms called compartments. Four of the compartments are available for sleeping. These are the Forward Torpedo Room (10 bunks), After Torpedo Room (10 bunks), Crew's Quarters (36 bunks) and Officers' Quarters (3, 4 and 5 bunks).
The Trident Refit Facility (TRF) is the largest tenant command at Kings Bay and has kept a significant portion of the United States Fleet Ballistic Missile submarines at sea since 1985.
