readx; The technical specifications of the "Great Soviet" class of May 13, 1939 were as follows: design standard displacement of 259,150 tons, full load displacement of 265,150 tons. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 The total length of the info is 538.8 meters, the waterline length is 520 meters, the maximum width is 77.8 meters, the waterline width is 72.8 meters, the draft is 20.8 meters at full load, and the depth is 33.4 meters. The freeboard heights of the bow and stern are 19.2, 12.7 and 17.9 meters respectively, the design initial stability is 6.8 meters high, and the length to width ratio of the hull is 7.14:1, which is relatively fat. The main turret is laid out in the front and in the rear, and the appearance and overall arrangement are clearly similar to the UP-41. Since the UP-41 itself is a modification of the "Veneto", it is not too much for Western countries to jokingly call the "Soviet" class "Venetosky". The crew was 3,328 men, including 224 officers, 452 warrant officers and 2,562 sailors (2,584 men, including 132 officers, 350 warrant officers and 2,102 sailors, which was obviously too small for the "Great Soviet" class).

The "Great Soviet" class was armed with 3 triple MK-1 530-mm main turrets, which were designed on the basis of the 406-mm turrets of the Tsarist era, produced by the Leningrad "Barricades" and "Bolshevik" factories, and the first test firing was carried out only in 1940. The turret was mounted to the ring base using a set of ball bearings containing 300 balls of 406 mm diameter, and another 408 vertical rollers were used to withstand the recoil of the turret when firing from the gun. The gun pitches independently, fixed at +6 degrees for reloading. After taking into account the gun pitch time, the sustained rate of fire of the gun at elevation angles less than 20 degrees, 20-27.5 degrees, 2.75-30 degrees and 30-40 degrees elevation was 5.2, 5.0, 4.8 and 1 round per minute, respectively. The turret ammunition base is 600 rounds, and there are 612-624 full-yield kits. The 3 guns were divided into separate fireproof fighting compartments with 4 120-mm armor plates. The B-37 530-mm gun was scheduled to be produced at 380 units, but until the construction of the other three ships of the "Great Soviet" class program was cancelled, the total production was only 16 guns. The 500, 500, 533 and 570 mm guns, which had been discussed at the design stage, were all cancelled due to technical difficulties. During the Battle of Leningrad, 530-mm guns took part in artillery battles against German long-range artillery.

The Type 24 is armed with 12 twin 152mm secondary guns with a reload angle of +8 degrees. The elevation angle of 16 degrees was 7.5 rounds / min at **, and the rate of fire between 30-40 degrees was reduced to 4.8 rounds / min. There were also 8 twin 100-mm anti-aircraft guns, and in January 1941, four twin turrets were added to the aft deck. The light anti-aircraft weapons of the "Great Soviet" were attractive, she was armed with 16 46-k quadruple 37-mm guns with stabilizers. At that time, other countries did not have similar advanced designs.

The fire control system of the "Great Soviet" class has been a mystery for a long time, and only after a considerable amount of information has been declassified has it been possible to get a glimpse of the leopard. The "Great Soviet" class is equipped with 3 kДП-8 gun firing commanders, two of which are located on top of the front and rear conning towers, and the other on the roof of the foremast. Among them, the top of the command tower is Type II, and its side armor thickness is 100 mm, and the armor of the other two Type I commanders is 40 mm thick. The conductor is equipped with 2 stereo rangefinders of the Дm-8-1 type, which have a unique appearance. One rangefinder is used to determine the target, and the other is responsible for observing the deviation of the ship's projectiles. The ship-** strike command post is equipped with one set of ЦАc-0 electromechanical ballistic solvers and one automatic coordinate transformer of the Пk-3 type. The whole set of main gun fire control devices can carry out omnidirectional calculation of targets within a range of 25 nautical miles and a speed of no more than 42 knots. In addition, each main turret is equipped with one Дm-12 rangefinder, the Дm-12 has a baseline length of 12 meters, which is the longest optical rangefinder made in the Soviet Union, using some German technology. The secondary guns were provided with firing elements from 4 commanders of the kДП-4t-ii type, each of which had 2 Дm-4 rangefinders. Under the control of kДП-4t-2, the secondary gun could fire both at surface targets and at aircraft at low altitudes and low speeds. The 100-mm anti-aircraft gun group was commanded by 3 cПh-300 anti-aircraft guns with stabilizers. cПh-300 is arranged on the head and tail line of the superstructure, there is 1 Дm-4 rangefinder. Thanks to the stabilizer, the cПh-300 can carry out effective and stable tracking of air targets within 360 degrees with severe swaying of the hull.
