How did submarines help in ww2?
Submarines not only attacked enemy ships, but also rescued downed pilots, and played other humanitarian roles. American submarines had the largest impact on the Imperial Japanese Navy and merchant ships, destroying their supply lines and extensive naval fleet.
What was life like on a ww2 submarine?
The engine room temperature could soar to over 100 degrees before spreading throughout the sub. Combine that with the 80 men working and breathing and the air inside could quickly become foul. The men knew the air was getting bad when they had trouble lighting their cigarettes due to the lack of oxygen (oh the irony).
Why did ww2 submarines have to surface?
World War II submarines were basically surface ships that could travel underwater for a limited time. Diesel engines gave them high surface speed and long range, but speed and range were severely reduced underwater, where they relied on electric motors powered by relatively short-lived storage batteries.
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.
Do submarines have cockroaches?
Cockroaches have been, since the days of sailing ships (Roth and Willis 1957), and continue to be, serious pests aboard naval vessels. Control of the German cockroach, Blattella germanica (L.), aboard U. S. Navy ships, particularly submarines, presents a unique and challenging opportunity for U. S. Navy entomologists.
How did ww2 Subs get oxygen?
There no plants to recycle CO2 either, so everything has to be done using some impressive technologies. 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.
Did WWII 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.

What did submariners eat in ww2?
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.
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.
What does the U in U-boat mean?
History and Etymology for U-boat
translation of German U-boot, short for Unterseeboot, literally, undersea boat.
How long do subs 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.
Is it hot inside 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.
Are females allowed to work on submarines?
Women are to be allowed to serve on Royal Navy submarines, Defence Secretary Philip Hammond has confirmed. The first women officers will begin serving on Vanguard-class nuclear subs in late 2013.
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.
How did submarines impact the events and outcome of WWI?
Submarine warfare played an integral role in the mounting international pressures of World War I. After the war broke out in 1914, Great Britain used its powerful navy to blockade German ports to limit food, supplies, and war materials from reaching the German military and people.
What are submarines used for?
Civilian uses include marine science, salvage, exploration, and facility inspection and maintenance. Submarines can also be modified for specialized functions such as search-and-rescue missions and undersea cable repair. They are also used in tourism and undersea archaeology.
