 Slava 's 40 @-@ caliber 12 @-@ inch guns were mounted in two twin @-@ gun turrets , one each fore and aft . They had a rate of fire of about one round per minute . Sixty rounds per gun were carried . The twelve 45 @-@ caliber 6 @-@ inch ( 152 mm ) guns were mounted in six electrically powered twin @-@ gun turrets carried on the sides of the ship . They had a practical rate of fire of about three rounds per minute and were provided with 180 rounds per gun . Four of the twenty 75 @-@ millimeter ( 3 @.@ 0 in ) guns used against torpedo boats were mounted in casemates just below the forward main gun turret , two on each side . These guns were placed well above the waterline for use in any weather , unlike the remaining sixteen guns , which were mounted in casemates one deck lower and distributed over the length of the ship , close to the water . This was graphically demonstrated when Slava 's sister ship Imperator Aleksandr III made a high @-@ speed turn during her trials , heeling 15 ° , and began taking water through the lower casemates . Each gun had 300 rounds available . All but four of her 47 @-@ millimeter ( 1 @.@ 9 in ) Hotchkiss guns were removed before she was completed and the remaining guns were used as saluting guns . She carried four 15 @-@ inch ( 381 mm ) torpedo tubes , one above water in the bow and one in the stern with two torpedoes each , and a submerged tube on each side forward with three torpedoes each . Two of these were removed before 1914 , although it is not known which ones were retained .
