INSIDE A TORPEDO TUBE ON A US NAVY NUCLEAR SUBMARINE

Most of us know that a submarine can fire torpedoes, right, but how? Destin from SmarterEveryDay crawls down a torpedo tube on a US Navy nuclear submarine to find out.

If you haven't seen any of this series before, then I'll catch you up. During an exercise for ICEX, YouTuber, Destin from SmarterEveryDay, was given the incredibly honourable opportunity to climb aboard a US Navy fast-attack nuclear submarine named the USS Toledo.

The submarine was doing a series of testing under the thick ice of the Arctic ocean, and Destin tagged along. Previously, he gave us an overview of the command structure of the vessel, this time, he goes deeper... into the torpedo tube!

Yes, this is not something the average human would be allowed to do, which makes this video even more astounding. Not only does he get to climb into the tube, and sign his name on the inside of the muzzle door, but he explains how it all works.

Firing a torpedo is way more involved than firing a rocket simply because the submarine is submerged. There are so many factors to consider, such as equalising pressure, buoyancy and weight. They must also consider how air is moved around the vessel because, when you're submerged under the ice, it's way more difficult to surface if something goes wrong.

To find out how everything works, then press the play button below and join Destin and the sailors in charge of the torpedoes on the USS Toledo, it's fascinating stuff.
