Many players believe the automatic map updates are unrealistic, but the two things that the game doesn't simulate without it are (1) the officer on the attack team responsible for keeping the plot so the captain doesn't need to do it by himself, and (2) the automatic plotting table linked to the TDC position keeper. The automatic plotter was invented before world war one, by 1930 it was standard equipment on all US and British warships.

Automated fire control began in the navy with the adoption of “director firing,” which controlled all guns on a ship from a centralized location. Before World War I, Arthur Hungerford Pollen designed an early automated plotting system for British ships. In America, the Sperry Gyroscope Company connected instruments that collected observed data about a target into a central plotting room. An automatic plotter drew the paths of both the firing ship and the target ship on paper, from which a gunnery officer could read the range and bearing for the guns to fire. He then electrically transmitted these data to gunners in the turrets. In 1915, Sperry's chief designer, Hannibal Ford, left to start the Ford Instrument Company and introduced the Ford Rangekeeper, which both incorporated British technology and added new mechanisms of Ford design. The Rangekeeper, a mechanical analog computer, estimated the course and speed of a target ship based on repeated observations of range and bearing, continually updating the estimate in accord with new observations. The U.S. Navy enthusiastically adopted the Ford Rangekeeper, at first for battleships and then for destroyers and cruisers. Before World War II, the secret and novel military‐industrial alliance of the Bureau of Ordnance and the Ford Instrument Company, the Arma Engineering Company, and General Electric built nearly all fire control systems for the navy. Ford Rangekeepers, in numerous updates and modifications, directed guns on American warships into the 1990s. Arma also designed the famous Torpedo Data Computer (TDC) for submarines and surface ships. Sperry and another spinoff, Carl Norden Inc., began building bombsights, a technology similar to Rangekeepers that played a critical role in World War II.
