Seas of Thunder: Global Naval Warfare 1939-45

Seas of Thunder: Global Naval Warfare 1939-45 is a strategic-level WWII naval game covering the worldwide struggle for control of the seas.

Players manage fleets across the Atlantic, Mediterranean, Arctic, Pacific, and other key naval theaters, deciding where to contest, where to raid, and where to accept risk. The game focuses on the constant pressure of having too much ocean to cover and never quite enough ships in the right places.

Each major naval power has its own strengths and problems. Germany relies on raiders and submarines, Britain must defend a global network of sea lanes, Italy fights for local dominance in the Mediterranean, Japan begins with major strength but faces growing Allied power, and the United States must decide how to divide its expanding fleet across multiple fronts.

At its heart, Seas of Thunder is a large area-control game, but the decisions are deeply naval: carriers, battleships, submarines, minesweepers, land-based air, convoys, and raiders all create different threats and priorities. Scenarios can be played separately or combined for a broader campaign.

This is a strong choice for players who enjoy strategic WWII games with global scope, asymmetric naval powers, and constant deployment dilemmas.

Contents include: double-sided game map, rules booklet, combat sequence mats, port mats, five countersheets, and twelve six-sided dice.
