Initially seven mounts were planned, but the one above the conning tower was exchanged for a director for the 100 mm guns in early 1940 when the Navy realized that the other directors were blocked by the superstructure. 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 Kronshtadt Class Battlecruiser was the lighter Soviet counterpart to the Sovetskaya Rossiya-class battleship. The Stalingrad-class battlecruiser, also known as Project 82 (Russian: Тяжёлые крейсера проекта 82), was a Soviet battlecruiser design from 1941. Kronshtadt-class battlecruiser is part of the Battlecruisers of the world series, a featured topic. 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 Kronshtadts were specifically built to counter the threat of the german Bismarck-class. Ive been reading up on the Lexington and G3 class battlecruisers and looking at how the Devs would classify them if they ever show up. They could elevate to a maximum of 85° and depress to -8°. [4], The Soviets never did get the detailed data required to redesign the ship's barbettes and magazines, but they did know that the 380-mm barbettes was bigger in diameter than that of the 305 mm turret as well as taller than the Russian turrets. This meant that the main belt had to be extended upwards to meet the main armor deck at a significant penalty in weight. [10], The main armament consisted of three electrically powered triple-gun turrets, each with three 54-caliber 305 mm B-50 guns. Their maximum range was 8,000 meters (26,247 ft). Germany and Russia designed new battlecruisers during this period, though only the latter laid down two of the 35,000-ton Kronshtadt class. 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. A battlecruiser, or battle cruiser, was a large capital ship built in the first half of the 20th century. The Soviets considered converting her into an aircraft carrier, but the idea was rejected and both hulls were scrapped in 1947. But in 1944, Soviet premier Joseph Stalin rebooted the concept for a namesake ship, the Stalingrad-class battlecruiser. https://naval-frontline.fandom.com/wiki/Kronshtadt_class_battlecruiser This list may not reflect recent changes . The funnels had 20 mm armor for their entire height above the deck and a 50 mm box protected the smoke generators. These ships had a complex and prolonged design process which was hampered by constantly changing requirements and the Great Purge in 1937. She was laid down 30 November 1939 and judged 10.6% complete when the Germans invaded. A revised, 35,000-ton design with 152-millimeter (6.0 in) guns and extra armor was submitted to the State Defense Council in January 1939. So the barbette of turret number two had to be raised to clear turret number one and the height of the conning tower had to be raised to clear turret number two. Kronshtadt-class battlecruiser: | | | ||| | Side view as the design appeared in ear... World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled. 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. [1], However the Soviet Navy still felt a need for a fast ship that could deal with enemy cruisers and the original concept was revived as Project 69. This meant that a lot of horsepower was necessary to achieve even modest speeds. Their rate of fire was 2.3 rounds per minute. The normal fuel oil capacity was 2,920 metric tons (2,874 long tons), which provided an estimated endurance of 1,100 nautical miles (2,000 km; 1,300 mi) at full speed. Two ships were started but … 3 x twin 15 in guns. By this time, however, details were becoming available for the Scharnhorst-class battleships and the ship was deemed inferior to the German ships. [13] They could traverse at a rate of 12° per second and elevate at 10° per second. The main calibre was … [14], Heavy anti-aircraft (AA) fire was provided by eight 56-caliber 100 mm B-34 dual-purpose guns in four twin turrets mounted at the aft end of the superstructure with the aft turrets mounted inboard of the forward turrets. [17], The Germans sold the Soviets twelve 52-caliber 38-centimeter (15.0 in) SKC/34 guns and their associated Drh LC/34 turrets as part of the Molotov–Ribbentrop Pact. A total of sixteen ships were planned in the August 1939 building program, but this was scaled back to four in July 1940 and two in October 1940 when it became clear just how unprepared the Soviets were for any large-scale naval construction program. 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 … The forward turrets were inboard and above the outer turrets which provided both turrets with good arcs of fire. Furthermore, the armor plants proved to be incapable of making cemented plates over 230 mm and inferior face-hardened plates had to be substituted for all thicknesses over 200 millimeters (7.9 in). We will never know how this Battlecruiser would perform in battle, as the two ships of the class: Kronshtadt and Sevestapol would never be completed, due to the aforementioned limitations of Soviet heavy industries at the time, and the eventual commencement of the Great Patriotic War; with most of their resources reallocated for other uses. The Soviets envisioned one of these projects, the Kronshtadt-class battlecruiser, to be faster than Germany’s Bismarck-class battleship and more powerful than the Scharnhorst. He then asked if twin 380-millimeter (15.0 in) turrets could be used instead. 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. It was a smaller and less-expensive counterpart to the Kronshtadt-class battlecruisers of 1939. As designed they displaced 35,240 metric tons (34,683 long tons) at standard and 41,539 metric tons (40,883 long tons) at full load. But in 1944, Soviet premier Joseph Stalin rebooted the concept for a namesake ship, the Stalingrad-class battlecruiser. If you can update or improve them, please do so. The Soviets envisioned one of these projects, the Kronshtadt-class battlecruiser, to be faster than Germany’s Bismarck-class battleship and more powerful than the Scharnhorst. The Navy's Shipbuilding Administration thought that the original secondary armament of 130-millimeter (5.1 in) guns was too small and that the armor on the turrets, conning tower and the forward transverse bulkhead was too thin. The Kronshtadt-class battlecruisers are a class of battlecruisers developed in the 1930s by the Soviet Union for the Soviet Navy in the early 1930s. Two ships were started but none were completed due to World War II. [8], The Kronshtadt-class ships were provided with two KOR-2 flying boats which would be launched by the catapult mounted between the funnels. The single-reduction, impulse-reduction geared steam turbines were an imported Brown Boveri design shared with the Sovetsky Soyuz-class battleship, but the factory in Kharkiv that was to build them never finished a single turbine before the Germans invaded. Alas, the demands of the war saw that the Kronshtadt was never built. : Kronshtadt-class battlecruiser is part of the Battlecruisers of the world series, a featured topic.It is also part of the Battlecruisers of Russia series, a featured topic. These ships had a complex and prolonged design process which was hampered by constantly changing requirements and the Great Purge in 1937. Each of the directors had 14 mm of armor as did the 37 mm gun mounts. Alas, the demands of the war saw that the Kronshtadt was never built. The Kronshtadt-class battlecruisers, with the Soviet designation as Project 69 heavy cruisers, (Тяжёлые крейсера проекта 69 ), were ordered for the Soviet Navy in the late 1930s. [9], Maximum speed was estimated at 31 knots (57 km/h; 36 mph), using the revised propeller design, although forcing the machinery would yield an extra knot. Side view as the design appeared in early 1939. The largest warships built in the Soviet Union prior to 1938 were the 8,000-metric-ton (7,874-long-ton) Kirov-class cruisers and even they had suffered from a number of production problems, but the Soviet leadership preferred to ignore the industrial difficulties when making their plans. Maximum fuel capacity was 5,570 metric tons (5,482 long tons) which gave a range of 8,300 nautical miles (15,370 km; 9,550 mi) at 14.5 knots (26.9 km/h; 16.7 mph) and 6,900 nmi (12,780 km; 7,940 mi) at 16.5 knots (30.6 km/h; 19.0 mph). The Kronshtadt-class battlecruisers, with the Soviet designation as Project 69 heavy cruisers, were ordered for the Soviet Navy in the late 1930s. The gun fired 470-kilogram (1,040 lb) armor-piercing projectiles at a muzzle velocity of 900 m/s (3,000 ft/s); this provided a maximum range of 47,580 meters (52,030 yd). Until 1989 not even a tentative general arrangement drawing had been published; more was known She was laid down on 5 November 1939 and estimated as 11.6% complete on 22 June 1941. Two ships were started but none were completed due to World War II. 61 Kommunar yard at Nikolaev respectively. She was captured by the Germans when they occupied Nikolayev in late 1941, but the Germans did little with her other than to use some of her material for defensive positions and some was apparently shipped to Germany. So limit is higher than 30.5 cm. [6], The power plant was laid out on a unit system. Two ships were started but none were completed due to World War II. Subcategories. At this time the horizontal protection was revised after full-scale trials revealed that a 500-kilogram (1,100 lb) bomb would penetrate both a 40-millimeter (1.6 in) upper deck and a 50-millimeter (2.0 in) middle deck to burst on the main armor deck. 1939–1940 and a number of batches were rejected because they did not meet specifications main battery? kronshtadt class battlecruisers!
