Engineers Hard At Work on Updated Submarine Designs
Believe it or not, submarines have been used for warfare since the American Revolutionary War (though they wouldn't be used successfully until much later). Of course, submarine technology has advanced by leaps and bounds since the first primitive submarines took to the seas. Today, in order to avoid detection by enemy sonar, submarines must operate a minimum of 100 metres below the "Sonic Layer Depth", which means they must be made of metals that can withstand intense pressures.
