at and at full speed. Maximum fuel capacity was which gave a range of at 14.5 knots and at full speed. Armament The main armament consisted of three electrically powered MK-1 triple turrets, each with three 50-caliber 406 mm B-37 guns. The guns could be depressed to −2° and elevated to 45°. They had a fixed loading angle of 6° and their rate of fire varied with the time required to re-aim the guns. It ranged from 2.0 to 2.6 rounds per minute depending on the elevation. The turrets could elevate at a rate of 6.2 degrees per second and traverse at 4.55 degrees per second. 100 rounds per gun were carried. The guns fired projectiles at a muzzle velocity of ; this provided a maximum range of . The secondary armament consisted of twelve 57-caliber B-38 152 mm guns mounted in six twin-gun MK-4 turrets. Their elevation limits were −5° to +45° with a fixed loading angle of 8°. Their rate of fire also varied with the elevation from 7.5 to 4.8 rounds per minute. They were provided with 170 rounds per gun. The turrets could elevate at a rate of 13 degrees per second and traverse at 6 degrees per second. They had a maximum range of about with a shell at a muzzle velocity of . Heavy anti-aircraft (AA) fire was provided by a dozen 56-caliber 100 mm B-34 dual-purpose guns in six twin-gun MZ-14 turrets with 400 rounds per gun. The ships began construction with only four turrets, but two additional turrets were restored to the quarterdeck in January 1941. They could elevate to a maximum of 85° and depress to −8°. They could traverse at a rate of 12° per second and elevate at 10° per second. They fired high explosive shells at a muzzle velocity of ; this provided a maximum range of against surface targets, but their maximum range against aerial targets was , the limit of their time fuse. Light AA defense was handled by ten quadruple, water-cooled, 46-K mounts fitted with 70-K guns with 1800 rounds per gun. Initially only eight mounts were planned when the ships began construction, but two more were added later, probably in January 1941, one on each side of the forward superstructure. Each mount was fully enclosed to protect the crew from the muzzle blast of the larger guns and against splinters. The guns fired shells
