About this trail:
Submarines are incredible pieces of technology. Not so long ago, a naval force worked entirely above the water; with the addition of the submarine to the standard naval arsenal, the world below the surface became a battleground as well. The adaptations and inventions that allow sailors to not only fight a battle, but also live for months or even years underwater are some of the most brilliant developments in military history.

Submarines are ships that can operate both under and on top of the water. One of the first submersible vessels was built around 1620 by a Dutchman named Cornelius van Drebbel. We don't know that much about Drebbel's vessel, but diaries and books written at the time tell us his sub was really just a rowboat covered with a waterproof leather skin

To function underwater, submarines are built a bit differently than surface ships that float on the water's surface. In order to travel underwater, submarines must function in agreement with some key laws of nature, including Archimedes' Principle and Boyles' Law.
