Kaganovich (

Kaganovich was 187 m (613 ft 6 in)

Kaganovich carried nine 180 mm (7.1 in) 57-caliber B-1-P guns in three electrically powered MK-3-180 triple turrets. The turrets were very small; they were designed to fit into the limited hull space available and were so cramped that their rate of fire was much lower than designed—only two rounds per minute instead of six. The guns were mounted in a single cradle to minimize space and were so close together that their shot dispersion was very high because the muzzle blast from adjacent barrels affected each gun. Unlike her half-sisters built in European Russia, her secondary armament initially consisted of eight single 85 mm (3.3 in) 90-K dual-purpose anti-aircraft guns. Kaganovich's initial light AA armament is unknown, although her sister ship Kalinin's initially consisted of six semi-automatic 45 mm (1.8 in) 21-K AA guns with 600 rounds per gun, ten fully automatic 37 mm (1.5 in) 70-K AA guns with a thousand rounds per gun, and six DK 12.7 mm (0.50 in) machine guns with 12,500 rounds per gun. During the 1950s her light anti-aircraft armament was replaced by nine powered 37 mm V-11 mounts.^[3]

Six 533-millimeter (21 in) 39-Yu torpedo tubes were fitted in two triple mountings, one on each side. She received the Lend-Lease ASDIC-132 sonar system, which the Soviets called Drakon-132, as well as the experimental Soviet Mars-72 system.^[4]

Kaganovich's radar suite is unknown, but it is likely she was equipped with a mix of Soviet and British and American Lend-Lease radars.^[4] At some point during the 1950s her radars were replaced by modern Soviet-built radars; Gyuys for air search, Rif for surface search, Zalp for main-armament gunnery and Yakor' for anti-aircraft gunnery.^[5]
