Ship project history: First turbine-driven cruisers of the Russian fleet, projected taking into account experience of the Russian-Japanese war. They were built by two little differing series: Svetlana, Admiral Butakov, Admiral Spiridov and Admiral Greig for Baltic, Admiral Nahimov, Admiral Lazarev, Admiral Istomin and Admiral Kornilov for Black sea. All 8 ships were laid down prior to the beginning of the First World War, but any of them before revolution of 1917 was completed. 24/12/1920 the program has been accepted, according to which Svetlana and Admiral Nakhimov it was supposed to complete under original project.
   Black Sea cruisers, according to the project, differed by increased displacement (7600t against 6800), dimensions, and also type and structure of machinery (Parsons turbines and 14 Yarrow boilers instead of 4 Curtis-AEG-Vulkan and 13 Yarrow-Vulkan boilers), in remaining ships were practically identical. Rather low-freeboard hull with a forecastle and a three-funnel outline profile gave them a certain likeness with Novik class destroyers. On trials Profintern made 29.5kts at 6800t displacement and 59200hp power. Chervona Ukraina shown average speed of 29.82kts and maximum 30.9kts To the beginning of Great Patriotic war boilers were converted to pure oil-firing, but speed characteristics nevertheless have notably decreased: so, in 1941 speed did not exceed 27.5kts, and in 1944 Krasny Krym made no more than 22kts.
    Protection ensured unvulnerability from gunfire of destroyers. The main 75mm belt reached full ship length and adjoined an upper edge a lower deck. Above it the upper 25mm belt placed. Upper and lower decks had 20mm thickness. The protection of the same thickness covered funnel uptakes below deck level.
    Deck-casemates arrangement of artillery and insufficient to measures of the Second World War calibre were a serious lack of the project.
   
Ship protection: Main 75mm belt had 2.1m height and extended at all length except short part near aft end, closing aft by 50mm bulkhead; aft end of ship was protected by 25mm armour. Upper 25mm belt extended from stem to stern and from main belt to upper deck. Upper and flat main decks had 20m thickness and connected with upper edges of main and upper belts.
