They wanted a ship not to exceed 23,000 metric tons with a speed of 34 knots (63 km/h; 39 mph) and an armament of nine 254 mm guns, but the requirement proved to be too ambitious for the specified size and it increased to 26,200 metric tons (25,786 long tons) in the design submitted in June 1938. However, World War I and the Russian Civil War interrupted the construction of the Russian Borodino-class ships and all were scrapped. They were laid down in 1939, with an estimated completion date in 1944, but Stalin's naval construction program proved to be more than the shipbuilding and armaments industries could handle. The Kronshtadt-class battlecruisers had their origin in a mid-1930s requirement for a large cruiser (Russian: bol'shoi kreiser) capable of destroying 10,000-long-ton (10,160 t) cruisers built to the limits imposed by the Washington Naval Treaty, to which the Soviets were not a signatory. [3], It was already apparent that the 305 mm guns and turrets were well behind schedule when Joseph Stalin asked the German representatives in Moscow on 8 February 1940 to negotiate a trade agreement if it would be possible to use the triple 283-millimeter (11.1 in) turrets in lieu of the triple 305 mm turrets of the Project 69 ships. Traditional Soviet secrecy about technical naval matters had The speed remained the same as the deeper draft was offset by a more efficient propeller form. It asked for another design, displacing 23,000 metric tons (22,637 long tons) and armed with 254-millimeter (10.0 in) guns, in early 1936, eventually designated Project 22, but this design was cancelled after the Soviets began negotiations in mid-1936 with the British that ultimately resulted in the Anglo-Soviet Quantitative Naval Agreement of 1937 and agreed to follow the terms of the Second London Naval Treaty which limited battleships to a displacement of 35,000 long tons (35,562 t). [22], Side view as the design appeared in early 1939. This page was last edited on 9 January 2021, at 09:08. Shipbuilding steel proved to be in short supply in 1939–1940 and a number of batches were rejected because they did not meet specifications.

She was judged obsolete and the Soviets considered converting her into an aircraft carrier, but the idea was rejected and both hulls were scrapped in 1947. Photo via German Federal Archives. The main armor deck, which was even with the top of the waterline belt, was 90 millimeters (3.5 in) thick and a 30-millimeter (1.2 in) splinter deck was underneath it, although it tapered to 15 millimeters (0.59 in) in thickness over the torpedo protection system. 1,500 tons (2 active, 3 building) Vasily Bykov (2018) and Dmitriy Rogachev (2019) Novorossiysk, Black Sea Fleet Buyan and Buyan-M Class LOA 203' and 246' TDISP… Both ships, Kronshtadt and Sevastopol were commissioned in 1936. They had a maximum range of 36,520 meters (39,940 yd) with a 800-kilogram (1,800 lb) shell at a muzzle velocity of 820 m/s (2,700 ft/s). The admiral's bridge was protected with 50 mm armor. The State Defense Committee revised the requirements and specified a size about 31,000 metric tons (30,510 long tons), an armament of nine 305-millimeter (12.0 in) guns, an armor belt 250 mm (9.8 in) thick and a speed about 31–32 knots (57–59 km/h; 36–37 mph). They could elevate to a maximum of 85° and depress to -8°. The Project 25 design was then rejected on the grounds that it was too weak compared to foreign ships and the whole program was cancelled in early 1938 after an attempt to modify the design with larger guns had been made. [12], The secondary armament consisted of eight 57-caliber B-38 152 mm guns mounted in four dual MK-4 turrets concentrated at the forward end of the superstructure. The Kronshtadt class battlecruisers would have displaced some 42000 tons, and probably would have carried either 9 12” guns in three triple turrets of six 15” guns in three twin turrets. Lightning in the night Soviet battleships and Cruisers It is mention in Lightning in the night book that the Soviet Navy has eight battleships in service at the beginning of the war on Augusts 1st 1945.As the Soviet Union is at paece whit the United Greater German Reich (OTL Third Reich) all Battleships and Cruisers which whereunder constructionare completed. 1/1800th scale Kronshtadt-class submarine chaser. Contents The upper deck was only 14 millimeters (0.55 in) thick and was intended to initiate shell and bomb fuzes. The guns could be depressed to −3° and elevated to 45°. 380–86. Their rate of fire also varied with the elevation from 7.5 to 4.8 rounds per minute. Two ships were started but none were completed due to World War II. The original role was for a light, fast ship intended to break up attacks by British fast-cruiser forces that might attempt bombardment of Russia's northern ports. [16] The guns fired .732-kilogram (1.61 lb) shells at a muzzle velocity of 880 m/s (2,887 ft/s). The tactical diameter was estimated at about 1,200 meters (1,312 yd). The Kronshtadt-class battlecruisers, with the Soviet designation as Project 69 heavy cruisers, (Russian: Тяжёлые крейсера проекта 69), were ordered for the Soviet Navy in the late 1930s. The metacentric height was 2.8 meters (9 ft 2 in) for the 305 mm gunned ships, but dropped to 2.58 meters (8 ft 6 in) in the 380 mm gunned ships. ... the French Dunkerque class, and the modified Japanese Kongo class, which demanded a Soviet response. 428-GX-K-112540 (26528904530).jpg 2,093 × 1,398; 680 KB. Additionally, vessels of this class in Chinese service are used to take Chinese children enrolled in military / naval summer camps and junior military / naval academies for short cruises for patriotic education and public relations missions. These had two 8-meter (26 ft 3 in) stereoscopic rangefinders, one to track the target and the other to measure the range to the ship's own shell splashes. There were two other small boilers for harbor service and to power the auxiliary machinery. The belt was 185 meters (606 ft 11 in) long and covered 76.8 percent of the waterline; forward of this was a 20 mm belt that extended all the way to the bow. Two KDP-4t-II directors, with two 4-meter (13 ft 1 in) rangefinders each, controlled the secondary armament. Slip was too short for her entire length so her stern was built Shipyard.
