Sea Power

Battleships, submarines and aircraft carriers. In the first episode we witness how warships become a major cause of World War I – and how sailors ultimately help put an end to it. We have a front-row seat for the biggest naval battle of the war and feel the horrors of unrestricted submarine warfare. At the end of the 19th century, the world of warships changed radically: steel replaced wood. On board ships of this era, sailors and officers set sail, facing the enemy and hoping for a safe return. The period is between 1864 and 1918. Steam engines replaced sails, technology and tactics were both improved. In the 20th century, ships have become faster, stronger and deadlier. Soon, a war the likes of which the world had never seen before was brewing. The film depicts the largest naval battle of the First World War and the unrestricted submarine warfare.

In the second episode we witness the demise of the Imperial German fleet – and the rise of Japan as a major power. Against the backdrop of the deadliest war the world has ever seen, we learn how submarines and aircraft carriers change naval tactics forever. The First World War had barely ended when a new one was announced, one also fought on the oceans. WWII features aircraft carriers, battle cruisers, destroyers, submarines. Naval battles play out on surface, underwater and in the air. The era of battleships ended. Aircraft carriers became the new symbols of power on the seas. U-boats come up against Allied destroyers in the Atlantic, who are armed with hedgehogs and depth charges. Nations staked their futures in naval battles. Warships played a role in the outbreak of the Second World War. The end of the war was ultimately sealed on board a warship.

In a moment where a new weapon has potentially made warships irrelevant, they become more important than ever. We are there when nuclear weapons first go to sea, and balance on the knife's edge of mutually assured destruction. With the end of World War II, the future of warships themselves is at stake: The use of atomic bombs calls into question the fundamental utility of warships. Nuclear age brings nuclear powered naval forces: carriers, submarines, frigates. In 1955, first nuclear powered submarine allowed crew to remain underwater forever. Nuclear energy is more than just a weapon: Nuclear-powered ships achieve ranges and speeds like never before. Nuclear-powered submarines can operate almost indefinitely. And remain invisible until they fire their missiles and torpedoes.
