Victory at Sea is the game of naval combat during the Second World War. Throughout 1939–45, the nations of the world duelled across the oceans across the globe, only to discover the fundamental nature of naval warfare changing in the face of rapidly developing technologies.
Although the United States of America contains a vast area of land, almost all of its allies and trading partners are overseas, and those interests require a powerful navy to support them.
For centuries, Japan's policy of seclusion (sakoku) saw it concentrate on coastal defences in order to repel foreign vessels. However, with the advances other maritime nations were making, it eventually became obvious that no longer would Japan be able to ignore the rest of the world.
The Kriegsmarine had to be virtually rebuilt after the First World War. Forbidden to own capital ships and submarines, Germany nibbled away at first one clause of the Treaty of Versailles, then another, until a powerful navy force existed.
Yamato (大和, "Great Harmony") and her sister ship, Musashi, were constructed shortly before the outbreak of World War II. They were the heaviest and most powerfully armed battleships ever constructed; armed with nine 18.1” Type 94 main guns – the largest guns ever mounted on a warship.
The Royal Navy of Great Britain was the world’s greatest navy at the outbreak of the Second World War. However, Britain went to war with mainly First World War-vintage vessels. Since the Royal Navy already possessed many powerful units, construction of the most modern designs was limited.
