 König Albert was armed with a main battery of ten 30.5 cm SK L / 50 guns in five twin turrets. The ship disposed of the inefficient hexagonal turret arrangement of previous German battleships; instead, three of the five turrets were mounted on the centerline, with two of them arranged in a superfiring pair aft. The other two turrets were placed en echelon amidships, such that both could fire on the broadside. The ship was also armed with fourteen 15 cm (5.9 in) SK L / 45 guns in casemates amidships, eight 8.8 cm (3.5 in) SK L / 45 guns in casemates and four 8.8 cm L / 45 anti-aircraft guns. The ship's armament was rounded out by five 50 cm (19.7 in) torpedo tubes, all mounted in the hull.
