Therefore, all they need to do is somehow remove the salt content from the water.Īnd that’s precisely what they do. Precisely! They are submerged in water almost all the times for God’s sake! The only fly in the ointment is that the water they’re surrounded by is salinated, meaning that it tastes salty. Think about it – what’s the one thing that submarines have no shortage of? The question is, how can they get freshwater in the middle of an ocean? It’s not like the passengers have access to a municipal water supply like we do back in our homes, so they have to figure out a different and rather interesting way to get their hands on freshwater. So, what you need is a system in your submarine that can take care of the water needs of those passengers, maintain a comfortable temperature onboard, and most importantly, provide fresh, breathable air without interruption.Īlso Read: Why Do Submarines Have To Resurface At All?

One of the most common areas of application for submarines is the surveillance and defense of a country’s maritime borders. Submarines have become an integral part of navies from different nations all over the world due to their multi-faceted usefulness.

Short answer: oxygen is supplied onboard a submarine through pressurized tanks or an oxygen generator, while drinking water is obtained by desalinating seawater. The most notable thing about all of this is that a submarine “stays underwater for days”, which leads to a natural question… if a submarine is constantly surrounded by nothing but water, how does it have enough drinking water for its crew members? Even more importantly, how do the crew members get breathable oxygen, the most crucial requirement for the sustenance of human life? without any external support) underwater for days on end. In fact, that is just a brief rundown of what life in a submarine is like.Ī submarine, as you may already know, is a special ship designed to operate independently (i.e. Living in a metal tube hundreds of feet below the surface of the water in an ocean, away from all the hustle and bustle of life on Earth, surrounded by nothing but water and an eerie silence – all of this sounds like the perfect recipe for an exciting and adventurous trip.
