Parts of a Nuclear Submarine
The sail is a streamline portion that rises above the main body of the submarine. It consists of several different components, including horizontal diving planes, radar masts, communications antennas, and periscopes.
Ballast Tanks are located between the two hulls that were previously explained. The tanks help control the depth of the submarine by taking on or releasing the water that hits it. Trim tanks are located in the front and the aft of the submarine are also able to take on or release water in order to keep the submarine's weight equally distributed so it doesn't sink.
A nuclear reactor is a glorifies steam engine and is usually located around the aft of the submarine. It is protected by a thick metal casing that weight about 100 tons. An alloy inside of this is specially designed for protecting the radioactive fuel rods.
The sonar sphere is located in the front of the sub. Sonar radar helps a submarine detect other objects in the water. It works by sending out a sounds waves that will strike an object, sending a portion of the sound will be echoed back to the sub.
Atmosphere control equipment decontaminates the breathing air by getting rid of carbon dioxide and impurities.
Distilling plants purify saltwater to be used for the engine or for drinking water for the people aboard the submarine.
The torpedo room is where all torpedoes are stored and loaded into tubes that prepare them for launching.
The submarine's crew is housed and fed in a mess deck. The berthing area is located in the middle of the nose of the submarine, making it extremely small.
