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.

The 200-year evolution of the submarine in wartime is examined, told by the designers and engineers behind the machines.

A look at Naval warfare's fastest combat ships and how the advantage of speed determined the outcome of some of the great seas battles of the last 150 years.

An up-close look at the naval carriers, destroyers, and nuclear submarines of the Cold War.

Bad design, human error and the enemy sent great ships to tragic ends, like Britain's K13 submarine and HMS Hood, Sweden's 17th century Vasa, and Kublai Khan's fleet, sunk by the original kamikaze.
