per gun, and they had a rate of fire of about three shots per minute. The barrels had an expected life of two hundred full-power shots before they would need to be replaced. The guns were mounted in DrL C/11 turrets, which were electrically controlled, though the guns were elevated hydraulically. Each turret had a working chamber beneath it that was connected to a set of revolving ammunition hoists leading down to the magazine below it. One set of hoists retrieved the shells and propellant charges from the magazines and brought them to the working chamber, and another transferred them up to the gun house through flash-tight doors; this arrangement was adopted to reduce the risk of fire in the gun house from reaching the magazines. In an effort to reduce the possibility of a fire, everything in the turret was constructed of steel. The guns had a range of elevation from -8 to 15.5 degrees, which provided a maximum range of . Later in their careers, their mounts were modified to increase maximum elevation at the expense of depression, with the range now -5.5 to 16.5 degrees, increasing their range to . Muzzle velocity was . Secondary armament consisted of fourteen 15 cm SK L/45 quick-firing guns, each mounted individually in casemates in the forecastle deck, seven guns per broadside. Each casemate had its own set of magazines and ammunition hoists. These guns were intended for defense against torpedo-armed destroyers, and were supplied with a total of 2,240 shells. Their rate of fire was 4 to 5 shots per minute. The guns could depress to −7 degrees and elevate to 20 degrees, for a maximum range of . Their muzzle velocity was . The ships also carried six 8.8 cm SK L/45 quick-firing guns, mounted in casemates; previous German capital ships had carried a larger number of these guns, but by the time the König class was designed, the growth of destroyers had rendered the 8.8 cm gun of marginal use. The six guns were located on either side of the forward conning tower and were all directed forward. These guns were supplied with a total of 3,200 rounds, or 200 shells per gun, The guns could be elevated up to 25 degrees for a maximum range of . In addition, they were slated to carry four 8.8 cm SK L/45 anti-aircraft guns, which were to be mounted on
