One way the United States was able to defeat Germany during World War II was by overtaking a German submarine and stealing their Enigma machine.

During many wars, a submarine could transport supplies by hiding near the bottom of the ocean on their way to their destination.

While the sailors move around on the submarine, drops of water would frequently stream in the vehicle spraying them in the face.

When the captain of the submarine shot torpedoes in the direction of the enemy’s ship, he used the periscope to see if the enemy was destroyed.

A Navy’s submarine was equipped with many weapons, sailors and supplies before sailing out of port.
