Re: Deodorant + submarines Diesels don't have an issue with CO2, so no restriction. Besides with limited space you took only essentials with you to sea on patrol. There is no amount of deodorant that will cover the smell of diesel.
By tradition, some gendarmes may still grow a moustache. Submariners may be bearded, clean-shaven, or "patrol-bearded", growing a beard for the time of a patrol in reminiscence of the time of the diesel submarines whose cramped space allowed for rustic and minimal personal care.
This chemical, called amine, is known by every submariner (I was one for 3 years), as well as every submariner's wife, husband, or anyone else who encounters that sailor's laundry. However, a new CO2-capturing nanomaterial could bring an end to this most notorious of submarine smells (trust me, there are others).
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.
Submarines are considered “soft” targets. In other words, they are very fragile and are easily destroyed - if you can find one. Considering that you have to be able to get a seal with an EAB or OBA mask, shaving is pretty much considered a semi-routine.
Ectopic pregnancies, which are not statistically rare, would create additional emergencies requiring immediate, extremely hazardous, evacuations, sometimes in midocean. Britain, Canada and the U.S. Navy do not put women on submarines primarily because of these irresolvable health risks and operational complications.
No, it will be fine. Pressure inside the submarine is well controlled and essentially the same as regular atmospheric pressure.
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.
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.
The aim is to evade discovery by passive sonar by eliminating superfluous noise: nonessential systems are shut down, the crew is urged to rest and refrain from making any unnecessary sound, and speed is greatly reduced to minimize propeller noise.
It is perhaps surprising to think that there is actually space in a submarine for a smoking room. Indeed, it seems somewhat alarming that smoking is permitted given that there must be some (albeit small) increased fire risk.
Shipbuilders of the early years of shipping would use a copper coating as a biocide, to prevent organotins from sticking on the vessel's hull. That copper coating was responsible for the ship's red color. In the 21st century, it is more than obvious that antifouling coatings can be mixed with any color.
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.
According to the retired submariner, "a 'no drinking' rule is in force at sea".
"To recognise the unique ethos of the #SubmarineService within the @RoyalNavy, approval has been given for all qualified submariners, ratings and officers, to wear black cap covers as of today," he tweeted in July 2021. "Black covers will now be the default except for ceremonial events."
Submariners even wear tennis shoes when underway to silence their footsteps! To increase stealth, submariners take advantage of how sound waves act in ocean water. The speed of sound in seawater is greatly determined by temperature, pressure, and salinity.
There is also the etiquette of shower time -- three to five minutes being what these sailors constitute as being considerate of others since it is all about the "water run time" and the cycling out of dirty water for clean water these sailors must do.
For a recent deployment the Jefferson City loaded up with 9,800 pounds of flour, 1,200 pounds of chicken, 1,000 pounds of prime rib, 1,000 pounds of ground beef, 800 pounds of potatoes and 100 dozen eggs. In all, the submarine will typically carry about 15,000 pounds of food, or about 110 pounds per sailor per patrol.
While ZipRecruiter is seeing annual salaries as high as $160,000 and as low as $22,500, the majority of Submarine salaries currently range between $67,500 (25th percentile) to $122,000 (75th percentile) with top earners (90th percentile) making $148,500 annually across the United States.
Submarines are sometimes equipped with on-board devices that can connect to the internet with higher data rates, including via satellite, but these can only be used when submarines rise to the surface.
It has been suggested that a submarine in transit is 15-20 dB noisier than one in the "quiet" mode. It is also necessary to note that the noise level of a specific submarine doesn't remain constant.
Modern submarines can stay underwater without coming to the surface for several days. This means crew members can breathe the same air for an unusually long time. Dr Aleksandra Sebastian and co-workers from Lund University, Sweden, have studied how the quality of air on submarines changes over eight days of submersion.
Being on a submarine is very different to being on a boat. There is no rocking motion, as the submarine sits below the waves, and so people who get seasick on a boat will not do so on our 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.
With deployments underwater typically running 90 days, life onboard a submarine is anything but normal. Cramped quarters are the norm, and sailors must have the right technical know-how as well as determination to spend months underwater at a time.
