Passage: The Königs were armed with a main battery of ten 30.5 cm (12.0 in) SK L/50 guns in five twin turrets. Two turrets were mounted forward of the main superstructure in a superfiring pair, the third was placed on the centerline between the two funnels amidships, and the fourth and fifth turrets were also arranged in a superfiring pair, aft of the rear conning tower. Each gun turret had a working chamber beneath it that was connected to a revolving ammunition hoist leading down to the magazine below it. The turrets were electrically controlled, though the guns were elevated hydraulically. In an effort to reduce the possibility of a fire, everything in the turret was constructed of steel. The centerline arrangement was an improvement over the preceding Kaiser class, as all ten guns could fire on a wide arc on the broadside, and four guns could fire directly ahead, as opposed to only two on the Kaisers. The guns were supplied with 900 rounds, or 90 shells per gun. The 30.5 cm gun had a rate of fire of between 2–3 405.5-kilogram (894-pound) armor-piercing shells per minute, and was expected to fire 200 shells before replacement was necessary. The guns were also capable of firing 405.9 kg (894.8 lb) high explosive shells. Both types of shells were loaded with two propellant charges: an RP C/12 main charge in a brass cartridge that weighed 91 kg (201 lb) and an RP C/12 fore charge in a silk bag that weighed 34.5 kg (76 lb). This provided a muzzle velocity of 855 meters per second (2,805 ft/s). The turrets on the König-class battleships initially allowed elevation up to 13.5 degrees; this enabled a maximum range of 16,200 m (17,700 yd). After modifications, elevation was increased to 16 degrees, which correspondingly increased the range of the guns to 20,400 m (22,300 yd).Secondary armament consisted of fourteen 15 cm (5.9 in) SK L/45 quick-firing guns, each mounted in MPL C/06.11 casemates in the side of the top deck. These guns were intended for defense against torpedo boats, and were supplied with a total of 2,240...
