Navy SEALs have a pretty tough job, to say the least. These elite soldiers are ready to take on challenges in the harshest of conditions and come out with flying colors. SEALs are often dispatched from Navy submarines but a lot of folks don’t know how they work.
Like in science fiction stories with spaceships there is an airlock serves as the transitionary location of the submarine. The hatch is more commonly known as a lockout hatch which is a pressurized chamber to take then in and out of the sub.
A platoon of up to 14 SEALs goes into the lockout hatch, the top is unlocked and the main door sealed. At that point water filled the chamber giving time for water pressure inside to match the water pressure outside to prevent any potential harm from happening to the seals.
This compartment can also be used as an emergency exit for the regular crew if the worst should occur. This video shows a closer look at the lockout chamber and how it functions to dispatch Navy SEALs into action. Now you can tell your friends how they work the next time you see Navy SEALs in a movie.
