Before the Germans evacuated the city they damaged her building slip and hull with explosives and made her a constructive total loss. Country Builder Location Ship Class / type Notes 12 March Soviet Union Zelenodolsk Gorky Plant: Zelenedolsk: BO-198: Kronshtadt-class submarine chaser : 21 March Soviet Union Zelenodolsk Gorky Plant They had a fixed loading angle of 6° and their rate of fire varied with the time required to relay the gun. [20], The ships were originally intended to be laid down 1 September 1939, but they were delayed until November to allow improvements to the shipyards to be completed. ; Evan Mawdsley (1991). The speed remained the same as the deeper draft was offset by a more efficient propeller form. The lead ship of the Kronshtadt-class Sinks Graf Zeppelin 1944, Sinks Gneisenau in early 1947 in Black Sea Aircraft from the Boelcke and Peter Straßer sinks Kronshtadt prior to battle of Norwegian sea, March 25, 1947 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. Shipbuilding steel proved to be in short supply in 1939–1940 and a number of batches were rejected because they did not meet specifications. McLaughlin, Stephen (2004). 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). The secondary turrets had 100 mm faces with 50-millimeter (2.0 in) sides and roofs and 75-millimeter (3.0 in) barbettes. Work on these ships ceased shortly after the German invasion. The Project 25 design was accepted in mid-1937 after major revisions in the armor scheme and the machinery layout and four were ordered with construction to begin in late 1937 and early 1938. Their rate of fire also varied with the elevation from 7.5 to 4.8 rounds per minute. Stalin. Main features of USSR Destroyers: 1. 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. A revised design was finished by October which was wargamed against the Japanese Kongō-class battlecruisers, the French Dunkerque-class battleships as well as the Scharnhorst class. The riveted hull was subdivided by 24 transverse bulkheads and used longitudinal framing in the citadel, but transverse framing for the structure fore and aft of the citadel.

[10], The main armament consisted of three electrically powered MK-15 triple turrets, each with three 54-caliber 305 mm B-50 guns. They were designed in response to the battleships being built by Germany. Similarly the 37-millimeter (1.5 in) anti-aircraft guns behind turret number three had to raised as well. The order also included 10-meter (33 ft) rangefinders and 150-centimeter (59 in) searchlights. ... Kronshtadt, Tier IX Soviet Cruiser ” … "Project 69: The Kronshtadt Class Battlecruisers". By this time, however, details were becoming available for the Scharnhorst-class battleships and the ship was deemed inferior to the German ships. An attempt to import 14,000 long tons (14,225 t) of steel and armor plate from the United States in 1939 failed, probably as a result of the Soviet invasion of Poland on 17 September 1939. The Kronshtadts were specifically built to counter the threat of the german Bismarck-class. Project 122bis (NATO codename Kronshtadt class) submarine chasers were a Soviet design which were exported throughout the communist bloc in the 1950s. So the middle deck was thickened to 90-millimeter (3.5 in) with the lower deck intended to catch any splinters penetrating the armor deck. The Soviets had been working on a small battleship design (Battleship 'B') for service in the Baltic and Black Seas and had to shrink it as a result of these discussions to a size close to that of the Project 22 large cruiser so that the latter was cancelled. The ships were partially redesigned to accommodate them, after construction had already begun, but no turrets were actually delivered before Operation Barbarossa. Much of the design work was accomplished by using naval engineers abducted from the British Empire, Japan and United States (and later UAPR). [7], The hull form was very full with a block coefficient of 0.61 which compared badly to the 0.54 of the Dunkerque, the 0.52 of the German O-class battlecruiser or the 0.5266 of the American Alaska-class cruiser. Type: Battlecruiser Service Period: 1936-1954 … The first ship, BO-270, was built at Zelenodolsk in 1945-1947 and a total of 227 were built for Soviet Navy (175) and border guard until 1955. Two ships were started but none were completed due to World War II. They could elevate to a maximum of 85° and depress to -8°. The dual-purpose mountings had 50 mm armor with 40-millimeter (1.6 in) barbettes. This model includes 7 ships on a sprue. [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. As well as this, twenty Project 357 (Libau class) despatch vessels were built on the same hull, but were lightly armed. The second boiler room contained four boilers and was followed by a turbine room for the central shaft. 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). [13] They could traverse at a rate of 12° per second and elevate at 10° per second. They had a maximum range of about 30,000 meters (33,000 yd) with a 55-kilogram (121 lb) shell at a muzzle velocity of 950 m/s (3,100 ft/s). [2], This was approved and the detailed design work began with the basic concept that the ship should be superior to the Scharnhorst-class ships and able to outrun the Bismarck-class battleships. Some of her material was used during the Siege of Leningrad to repair other ships and in defensive works, but she could have been finished after the end of the war. These ships had a complex and prolonged design process which was hampered by constantly changing requirements and the Great Purge in 1937. Thirteen of the decommissioned and disarmed ships were delivered to the DOSAAF Voluntary Society for use as training ships. 380–86. The first Chinese built unit entered service in 1957 and was designated as the, Качур П. И. Большие охотники за подводными лодками проекта 122а/122бис //. 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. Great for setting enemy Battleships on fire from a distance 5. 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. ... the French Dunkerque class, and the modified Japanese Kongo class, which demanded a Soviet response. This mean that the main belt had to be extended upwards to meet the main armor deck at a significant penalty in weight. This meant that a lot of horsepower was necessary to achieve even modest speeds. Санкт-Петербург, 2001. The forward transverse 330-millimeter (13.0 in) bulkhead was 330 mm thick while the rear bulkhead was 275 millimeters (10.8 in) thick. 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. The Kharkhovskii Turbogenerator Works never completed a single turbine before the German invasion in June 1941. Kirov-class missile cruiser at sea in 1986. Certain elements not to scale. Photo via German Federal Archives. Large in size with long Rudder Shift Time 3. [13] The turrets could elevate at a rate of 13 degrees per second and traverse at 6 degrees per second. As well as this, twenty Project 357 (Libau class) despatch vessels were built on the same hull, but were lightly armed. Twelve 7u-bis water-tube boilers worked at a pressure of 37 kg/cm2 (3,628 kPa; 526 psi) and temperature of 380 °C (716 °F). The model is an approximation and is not configured to represent either ship perfectly. 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. Battleship Gangut-class battleship … The turrets could elevate at a rate of 6° per second and traverse at 5° per second. Prototypes of neither had been completed by the time the Germans invaded. The guns could be depressed to −3° and elevated to 45°. It asked for another design, displacing 23,000 metric tons (22,637 long tons) and armed with 254-millimeter (10.0 in) guns, i… The Germans said that they would have to check back for the technical details. 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.
