From the rulebook:
Dreadnought is a two-player simulation of surface naval warfare in the period 1906 to 1944 with the primary emphasis on the role of the all big-gun battleship (Dreadnought) in fleet actions. Historical and non-historical battles and naval campaigns are presented. Essential elements of surface naval warfare are recreated, including gunnery, torpedoes, ranging, damage control, formation handling and fleet coordination.
Each Game-Turn represents 15 minutes of real time. Each hex represents 1800 meters from side to parallel side. Each movement point represents 4 knots of speed.
