    Warship Projects - Imperial Russian Navy/ USSR VMF

    Unrealized projects of submarines of the Russian Empire
  2. I apologize for bad English! The translation is carried out by an online translator with my changes. Big submarines (Большие субмарины) Project of the Metall plant Displacement: 350/400 t (here and lower metric tons, 1000 kg) Lenght: 52 m Width: 4,75 m Standart depth of immersion: 45,8 m Extreme depth of immersion: 91,6 m Engine: diesel Surface speed: 12-13 knots Underwater speed: 10 knots Range of action: 1000 on 8 knots (on surface), 100 on 5 knots and 40 on 10 knots (underwater) Torpedo weapon: (450 mm) 2 rostrum torpedo tube, 1 stern torpedo tube, 6 external torpedo tube systems of Dzhevetsky Description: The submarine with the diesel engine working under water and on surface. Under water the engine worked at the expense of special inventories of compressed air that owed provide higher speed of the course in comparison with electric motors, however movement time under water has been limited one days. Project of the engineers L. Matsiyevich and V. Zhuravlev (Проект инженеров Л. Мациевича и В. Журавлева) Displacement: 500/625 t Lenght: 61 m Width: 4,6 m Standart depth of immersion: 46 m Extreme depth of immersion: 92 m Engine: diesel Surface speed: 16 knots Underwater speed: 12,5 knots Range of action: 1000 on 16 knots (on surface), 150 on 12,5 knots (underwater) Torpedo weapon: (450 mm) 3 rostrum torpedo tube, 1 stern torpedo tube, 2 external torpedo tube systems of Dzhevetsky, 2x2 rotary torpedo tubes Description: The submarine with the diesel engine working under water and at a surface. Diesel worked on the closed cycle. From exhaust gases potash absorbed carbonic acid, nitrogen and oxygen were used further, water was condensed. Still a quantity of oxygen which in case of an exit from port was accepted by the boat from shore stations was added to nitrogen and oxygen. In comparison with a diesel electric submarine, such I shall have the radius of action 3,75-4 times bigger. Project of the Izhora plant Displacement: 360/410 t Lenght: 47,2 m Width: 4,27 m Extreme depth of immersion: 92 m Engine: diesel-electric Surface speed: 15 knots Underwater speed: 11 knots Range of action: 1200 on 10 knots (on surface), 200 on 5 knots or 42 on 11 knots (underwater) Torpedo weapon: (450 mm) 2 rostrum torpedo tube, 2 stern torpedo tube, 6 external torpedo tube systems of Dzhevetsky Squadron submarines (Эскадренные субмарины) Ivan Bubnov's project (Проект Ивана Бубнова) 1914 Displacement: 3500/3900 t Lenght: 120 m Width: ~8 m Extreme depth of immersion: 90 m Engine: steam-turbine-electric Surface speed (On a surface only cabins, the case is on depth about 19 m): ~25 knots Underwater speed: 3-4 knots Range of action (here and lower sea miles, 1852 m): 2-3 000 on 25 knots (on surface), 20 (underwater) Torpedo weapon: (450 mm) 2 rostrum torpedo tube, 2 stern torpedo tube, 10 onboard torpedo tube (90 degrees from a longitudinal axis), 10 deck torpedo tube. Description:The submarine had to have two high cabins which worked instead of periscopes. The submarine had an opportunity to attack, at the same time the case at a depth remained in safety. Project of Russian-Baltic plant (проект Русско-Балтийского завода) 1915 Displacement: 1988/2725 t Artillery weapon: 2x130 mm (B-13), 1x76,2 mm (Lender AA gun?) Torpedo weapon: (533 mm) 4 rostrum torpedo tube, 2 stern torpedo tube, 8 external torpedo tube systems of Dzhevetsky Del-proposto's project (italian engineer) (Проект Дель-Пропосто) 1915 Displacement: 2300/2500 t Lenght: 91 m Width: 7,8 m Extreme depth of immersion: 30 m Engine: steam-turbine with the thermal accumulator Surface speed: 25 knots Underwater speed: 7,5 knots Range of action: 7 300 on 25 knots (on surface), 200 on 7,5 knots (underwater) Torpedo weapon: (450 mm) 6 rostrum torpedo tube, 1 stern torpedo tube, 10 onboard torpedo tube (90 degrees from a longitudinal axis) Artillery weapon: 2x152 mm (Kanet), 4x102 mm (Obukhov plant) Naval mines: 150 Description: The submarine had the high armor cabin with tools on lifting machines. At artillery attack to the opponent over water only the cabin was visible, the case was under a sheet of water not less than 2 meters. The propeller of a special design was assumed though the author allowed ordinary propellers. The accumulator could be charged due to heat from coppers, in 40 minutes the accumulator was charged completely. Propeller of this submarine: Submarine of 1917 (Субмарина 1917 года): Standart depth of immersion: 50 m Engine: steam-turbine-electric Surface speed: 25 knots Underwater speed: 10 knots Torpedo weapon: (450 mm) 4 rostrum torpedo tube, 2 stern torpedo tube, 4 onboard torpedo tube (90 degrees from a longitudinal axis), 10 external torpedo tube systems of Dzhevetsky Artillery weapon: 2x102 mm (Obukhov plant), 1x75 mm (anti-aircraft) Naval mines: 10 Variants: Society of plants and shipyards of the town Nikolaev (Общество Николаевских заводов и верфей): Displacement: 1975/3140 t Lenght: 109,2 m Width: 9,2 m Shipbuilding plant of the town Revel (Tallin) (Ревельский судостроительный завод): Displacement: 3000/4400 t Lenght: 120 m Width: 11,2 m Putilov shipyard (Путиловская верфь): Displacement: 3000/4560 t Lenght: 119 m Width: 10,2 m Underwater cruisers (Подводные крейсера) Project of the independent underwater armour-deck cruiser of the engineer Zhuravlev (Проект автономного подводного бронепалубного крейсера инженера Журавлёва) Displacement: 4500/5435 t Lenght: 128 m Width: 10,4 m Standart depth of immersion: 116 m Extreme depth of immersion: 174 m Engine: steam-turbine-electric (A) / diesel-electric (B) Surface speed: 25 knots Underwater speed: 14 knots Range of action: (A) 15 500 on 11 knots and 730 on 25 knots (on surface), (B) 18 500 on 11 knots and 2350 on 25 knots (on surface), 275 on 6 knots and 21 on 14 cknots (underwater A and B) Torpedo weapon: (450 mm) 30 external torpedo tube systems of Dzhevetsky Artillery weapon: 5x120 mm (Kanet or Vickers) or 5x130 mm (B-7) in turrets Naval mines: 120 Armour: deck 19-51 mm, cabin and gun turrets 51-102 mm Description: The world's largest project of the submarine till 1945 and one of the most powerful. Gun turrets, the cabin and (in option A) chimneys were moving forward, at the expense of the hydraulic or pneumatic drive. The project was feasible, but admirals were frightened off by the big size and respectively high cost. Project of the underwater cruiser of Russian-Baltic plant (Проект подводного крейсера Русско-Балтийского завода) 1915-16 Displacement: 2800/? (~3200-3500) t Lenght: 113 m Width: 10,6 m Engine: diesel-electric Surface speed: more 20 knots (25?) Torpedo weapon: (533 mm) 4 rostrum torpedo tube, 2 stern torpedo tube, 8 onboard torpedo tube (90 degrees from a longitudinal axis) Artillery weapon: 1x2x120 mm (Kanet or Vickers) in sliding turret, 2x75 (anti-aircraft) Description: The project of the submarine more powerful, than B-1 (upgrade type "Bars"). Here I have written about the largest projects of submarines of the Russian Empire. There were a lot more projects, but they generally repeated "Bars" type submarine, they are almost not of interest therefore I about them haven't written.

    Tsarist battleship studies 1914-1916

    Experimental Russian gun 406/45 was very powerful. The gun made on Obukhov plant and which had the Russian gunpowder shot a shell at 1117 kg at a speed of 840 m/s that gave energy of 394 077 kilojoules that it is more, than at the American gun 406/50 - 1225 kg, 762 m/s, 355 644 kilojoules. The project of a gun 406/52 wasn't developed, but in case of creation it was possible to expect preservation of speed for increase in weight up to 1200 kg that gave energy in 423 360 kilojoules.
  4. In the book "Last Giants of the Russian Imperial Navy" it is written that this ship had belt thickness around a citadel of 400 mm, in extremities - 150 mm, beams - 300 mm. 450 mm were only in the fighting cabin. The image with the scheme 300-450-300 has no relation to this project. This scheme was assumed for battleships. Such ships were supposed to be used at least in couple... Unrealized projects of the Russian submarines also often had a large number of torpedo tubes. For example, there was a project of the underwater cruiser of the engineer Zhuravlev with the displacement of 4500/5435 tons, he had 30 external torpedo tubes of system Dzhevetsky and 60 torpedoes.

    Soviet H-44

    Source - the American data on firing of trophy armored plates for Sinano's battleship I think, they can be trusted.

    Soviet H-44

    The Japanese armor didn't differ in quality too - conceded British on durability almost on a third. And nothing, the Japanese battleships floated by the seas without problems.

    Soviet H-44

    It is my first post at the European forum, before I wrote at the Russian forum under Kubanetz_Krasnodar nickname. I apologize for bad English, the translation is carried out by mashine. Before development of detailed projects of the battleships - such as projects 21, 23 and 24 - in the Soviet Union foggier projects of the ships, some of them very monstrous were developed. Data of two such projects are given below. Unfortunately, I have not images. Project 1935 Speed: 26 knots Armament: 4x4x450 (457)* 12x100 mm universal gun (6x2 or 4x3) 16x45 (4x4) Armour: 380 mm belt 50-150 mm decks Project 1936 Speed: 24-28 knots Armament: 3x3x500 or 3x2x530 152 mm guns and 100 mm guns Armour: 500 mm belt *The Soviet hypothetical, and late design 457-mm gun had extremely big power. The weight of a shell made 1720 kg, the speed of 890 m/s, range of 52-55 km. Power made 681 206 kilojoules. Yamato - 1460 kg, speed has 805 m/s, range of 45 km - 473 058 kilojoules. The design German 508-mm gun to H-44 had the weight of a shell of 2000 kg, speed made apparently no more than 830-840 m/s, power made up to 705 600 kilojoules, at a speed of shell of 810-820 m/s power made up to 672 400 kilojoules. That is the Soviet 18-inch was approximately equal on power to German 20-inch. I don't know why, but these projects are known much less, than the German H-series. What will you tell about these projects?
