Submarines are an interesting kind of invention. Originally serving a military kind of purpose, now there also exist some submarines built for civilian use.
No matter the purpose, submarines are very interesting vessels. Imagine being able to submerge yourself underwater for a very long time. To be able to invent a vessel that can maintain itself stable under the unknown depths of oceans and seas is such a fantastic feat. To have this vessel contain many kinds of equipment, hold different kinds of people, and also store various kinds of weapons for fighting are good enough reasons to keep building them!
That's why it is always fascinating to watch movies that have scenes taking place inside a submarine. It's also a reimagining of what we humans could still invent and reinvent as the decades pass. Perhaps it's also part of humankind's insatiable desire to explore unknown regions of the earth, the galaxy, or the universe, that we will keep inventing mechanisms and vehicles for such purposes. At least that was how the submarine came to be -- aside from its very obvious use in warfare.
But can you name these familiar pieces of equipment found in a submarine, though? Take this quiz, and test your deep knowledge!
The periscope is probably the most recognizable submarine equipment ever. You use it to look at what’s happening outside.
The torpedo is usually carried by a submarine. This is the usual weapon associated with this vessel.
These are called diving planes. They’re useful to navigate the sub when it goes underwater.
This part is called the sail. It houses other equipment as well.
This is called a rudder. It’s very useful equipment for navigating the sub.
The propeller has the same universal function anywhere on any vehicle. It’s supposed to push it forward when it moves.
This is the submarine’s main ballast tank. There could be more than one in a sub.
The stern plane is useful equipment for actually controlling where the sub will go. It’s in charge of the course, in a way.
A deck gun looks like a huge machine gun. It has great firepower.
Sonar gear is very useful in a submarine. Sonar is actually an acronym which means Sound and Navigation Ranging.
Submarines also have fins. The ones in the front are called forward fins.
The aft is technically the back part of the submarine. So, the fins there are called aft fins.
Submarines are powered by many batteries. They’re in the battery bank somewhere inside.
The air conditioning plant is a necessary equipment system in a sub. Imagine if it’s hot in there!
This is called the radar mast. It co-exists with other mast equipment in its current spatial design.
The entrance to the submarine is covered by the main access hatch door. It’s that one you see on top.
A sub is also equipped with a radio antenna. It’s a necessary communications device.
The torpedo normally has a storage place. So, of course, it will also get ejected through its own torpedo tube.
A bulkhead pertains to a partition in the hull. In the submarine’s case, it’s that wall and complicated door contraption you see there, designed to be very watertight.
This is the communications mast. It’s built side by side with the other masts atop the sail.
This is the main electric propulsion motor. It’s important equipment to make the submarine move.
The photonics mast is the more high-tech equivalent of the periscope. Military grade submarines have this instead.
A hydrophone is indeed the cousin of a microphone. Only this is the kind used under water.
People inside a sub need headphones to listen closely to what they’re monitoring. So there are a lot of these there.
A lot of listening takes place inside a submarine. Naturally, it is equipped with receiver-amplifiers.
Supersonic gears are set up to listen to any kind of sound that’s not easily audible to the human ear. There are all types of sounds underwater!
Subs have a snort induction mast on the sail. It’s not as nasty as it sounds, y’all!
Subs also need a snort exhaust mast to let out smoke. It’s next to the snort induction mast.
A propeller always needs to be attached to a propeller shaft. Or else, it will not work!
Inside the sub, there are also loudspeakers for people to hear things. A sub could really be huge, so this is no surprise.
A submarine has different kinds of tanks, and the compensating tank is one of them. These tanks are used to balance the buoyancy of the sub, thereby affecting how it weighs during certain moments, like when it goes underneath the waters at a greater depth.
The escape hatch is different from the main access hatch. It’s good to differentiate them when you’re inside.
Negative tanks offer additional help to a submarine’s system when it comes to buoyancy. They are also called quick diving tanks.
Yup, a submarine also has an anchor. It has to dock sometime somewhere!
A submarine has to have intercom equipment. They’re needed so that people inside can talk to each other when working in different parts of the sub.
An Engine Order Telegraph has words that help to navigate the submarine. It’s actually a communication device.
Would you believe that there’s a nuclear reactor inside a submarine? That’s because some subs are designed to be powered by nuclear energy.
A submarine can also carry missiles. And yes, they get fired underwater, too.
All those buttons and dials! They’re part of the navigational control system, which is very important equipment inside a submarine.
