68bis Sverdlov class cruiser

The Sverdlov-class cruisers were improved and slightly enlarged versions of the Chapayev class. They had the same main armament, machinery and side protection as the earlier ships, but had increased fuel capacity for greater range, an all welded hull, improved underwater protection, increased anti-aircraft artillery and radar.

The Sverdlov class displaced 13,600 tons standard and 16,640 tons at full load. They were 210 m (690 ft) long overall and 205 m (673 ft) long at the waterline. They had a beam of 22 m (72 ft) and draft of 6.9 m (23 ft) and typically had a complement of 1,250. The hull was a completely welded new design and the ships had a double bottom for over 75% of their length. The ship also had 23 watertight bulkheads. The Sverdlovs had six boilers providing steam to two shafts with geared steam turbines generating 118,100 shaft horsepower (88,100 kW). This gave the ships a maximum speed of 32.5 knots (60.2 km/h; 37.4 mph). The cruisers had a range of 9,000 nautical miles (17,000 km; 10,000 mi) at 18 knots (33 km/h; 21 mph).^[​4]
