The main armament of the "Gangut"s consisted of a dozen 52-caliber Obukhovskii Pattern 1907 guns mounted in four triple turrets distributed the length of the ship. The Russians did not believe that superfiring turrets offered any advantage, discounting the value of axial fire and believing that superfiring turrets could not fire while over the lower turret because of muzzle blast problems. They also believed that distributing the turrets, and their associated magazines, over the length of the ship improved the survivability of the ship. Sixteen 50-caliber Pattern 1905 guns were mounted in casemates as the secondary battery intended to defend the ship against torpedo boats. The ships were completed with only a single 30-caliber "Lender" anti-aircraft (AA) gun mounted on the quarterdeck. Other AA guns were probably added during the course of World War I, but details are lacking. Conway's says that four 75mm 50 caliber Pattern 1892 were added to the roofs of the end turrets during the war. Four submerged torpedo tubes were mounted with three torpedoes for each tube.
