Watch Combat Ships live

Some of the greatest warships have gone on to shape the history of the world and have even pushed their crews into unbelievable and incredible acts of bravery. Take a look at the very first submarine which is rumored to have lurked beneath New York harbor during the Revolutionary War, the smaller ships that rescued thousands from Dunkirk, or the destroyer in the Cuban Missile Crisis. Over the years, conflicts and wars have prompted extreme advances to ship designs and now they are faster, stronger, and smarter than ever before.
