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. Z28 was the sole exception as its armament was arranged with two single mounts fore and aft. Z23, Z24, Z25 and Z29 were later fitted with the turret. All of the Type 36A (Mob) ships except Z31 were built with the turret and that ship received one later. The single mounts had a range of elevation from −10° to +30° while the guns in the turret could be elevated to 65°. The TbtsK C/36 gun fired projectiles at a muzzle velocity of which gave them a maximum range of . The hand-loaded gun had a maximum rate of fire of 7–8 rounds per minute and the ships carried a total of 480 shells for them. Their anti-aircraft armament consisted of four 80-calibre SK C/30 guns in two twin mounts abreast the aft funnel. The power operated mounts had a maximum elevation of 85° which gave the guns a ceiling of ; horizontal range was at an elevation of 37.5°. The single-shot SK C/30 fired projectiles at a muzzle velocity of at a rate of 30 rounds per minute. The mounts were stabilized, but their gyroscopes were undersized and could not cope with sharp turns or heavy rolling. They were also fitted with five to ten fully automatic 65-calibre C/30 guns in quadruple and single mounts. The gun had an effective rate of fire of about 120 rounds per minute. Its projectiles were fired at a muzzle velocity of which gave it a ceiling of and a maximum horizontal range of . The ships carried eight above-water torpedo tubes in two power-operated mounts. Two reloads were provided for each mount. The standard torpedo for the Type 36B destroyers was the G7a torpedo. It had a warhead and three speed range settings: at ; at and at . They had four depth charge launchers and mine rails could be fitted on the rear deck that had a maximum capacity of 60 mines. 'GHG' (Gruppenhorchgerät) passive hydrophones were fitted to detect submarines and a S-Gerät sonar was also probably fitted. The ships were equipped with a FuMO 24/25 radar set above the bridge.
