This is a large-caliber main gun developed and deployed by the US as the standard issue main weapon of their front-line battleships. This gun is a late-war upgraded model that is linked with an artillery radar and gun fire control system. Although it is slightly inferior to the newer Mk.7, it is a practical weapon that has high firepower and accuracy.
