The best I can piece together the impetus for these computers followed the Battle of Manila Bay, where Commodore Dewey's gun crews fired off a whole lot of ordinance for very few hits. At the time each gun crew sighted their own gun. By the Battle of Tsushima in the Russian-Japanese War the Japanese, if not the Russians too, must have had this kind of fire control on their British built ships. All done by slide-rule and machine tools.
