The main armament of the Type 1936A ships was intended to be five 45-calibre  15 cms TbtsK C/36 guns in a twin-gun turret forward and the three other guns in single mounts with gun shields aft of the main superstructure, but delivery of the turrets was delayed and all of the Type 36A class was delivered with four single 15 cm guns with one gun forward and three aft.
