I repost this with Giganaut’s permission, because this is simpke too good to pass up. As some of you know, there were actually numerous KV-4 proposals – some relatively simple, while others were completely outlandish. Let’s have a look at them. Giganaut_EU: Note: I modelled these in Google sketchup, with existing plans provided in Battlefield.ru with their collected data given – somewhat proved to be a bit insufficient because it was missing a few things. This thread could be the official if not centralized discussion thread for all KV-4s. This particular KV series is an interesting one in the Kliment Voroshilov heavy tank program. Its design purpose was to withstand any German gun and to destroy any opposing heavy German tanks. It was to remain unbuilt and its design proposals would be used if the time comes when it is needed. Designers began to work on the KV-4 design in April 1941. Since the Kirov Plant did not have experience in this area, the chief of the SKB-2, J.Kotin, assigned almost all the engineers of his design bureau to the design of this tank and made the task a competition. All the designers addressed this assignment with great enthusiasm. Their task was sufficiently difficult: the mounting of two cannons and 125-130 mm armor that had never been employed before on Soviet tanks led to the necessity to strengthen the chassis and required a sharp increase in the weight of the tank. Creative thinking of the participants in the design was not limited and the designers took advantage of this. When considering the required specifications, they developed and put forth a relatively diverse spectrum of ideas. They considered the design of 80-, 90-, and even 100-ton tanks. The lightest of the designs was submitted by engineer N.Dukhov – 82.5 tons. The heaviest was by the designer G.Kruchenykh – 107 tons. The layout decisions were also very diverse. Designers K.Buganov, G.Kruchenykh, F.Marishkin, G.Moskvin, N.Strukov, and S.Fedorenko, each working on his own design, suggested single-turret variants of the heavy tank with the mounting of the 107 mm tank cannon in the main turret, and a 45 mm tank cannon in a small turret located above the main turret, a “second floor” of sorts. Buganov’s proposal Specifications: (estimated size scaled to fit with KV-1’s road wheel) Length: 7.03m Width: 3.3m Height: 2.77m Ground clearance: 0.52m Combat weight: ? tons Engine: Diesel M-40, 1200hp Radio: 10-R series Crew: 5 Armor: Hull: 130/80/130 Turret: 135/130/130 Sec. Turret: 50/50/50 Armament: 1x 107mm Zis-6 2x 7.62mm DT 1x 45mm 20-K Fedorenko’s proposal A single-turret variant with the 107mm gun in the main turret and a 45mm in a miniturret above it. Specifications: (estimated size scaled to fit with KV-1’s road wheel) Length: 8.8m Width: 3.675m Height: 3.635m Ground clearance: 0.45m Combat weight: ? tons Engine: Diesel M-40, 1200hp Radio: 10-R series Crew: 6 Armor: Hull: 130/130/130 Turret: 140/140/140 Sec. Turret: 120/120/120 Armament: 1x 107mm Zis-6 3x 7.62mm DT 1x unknown gun (receiver in plan loos too big for a DT.) 1x 45mm 20-K (AA purposes) Pereverzev’s proposal Designers A. Yermolaev, L. Sychev, L. Pereverzev, Bykov, and two workers whose signatures are missing from the working drawings, suggested a two-turret variant of the tank with the mounting of a 107 mm cannon in a large central turret, as on the SMK tank, and a 45 mm gun in a separate turret located in the bow portion of the hull. Specifications: (scaled to KV-1 road wheel) Length: 9.4m Width: 3.57m Height: 3.45m Ground clearance: 0.5m Combat weight: ? tons Engine: Diesel M-40, 1200hp Radio: 10-R series Crew: 9 Armor: Hull: 140/125/130 Turret: 140 /130/130 Armament: 1x 107mm Zis-6 1x 45mm 20-k 4x 7.62mm DT Proposal 11 KV-4 that was done by an unknown author. so I decided to name it the KV-4-11, since it is named after it’s plan’s filename. Also, the tank is scaled to KV-1′s roadwheel, since it had the secondary turret on the front hull, so I’ll place this in the same category as Perevezev’s proposal. Specifications: tank scaled to KV-1s roadwheel Length: 8.317m Width: 3.572m Height: 3.121m Ground clearance: 0.561m Combat weight: ? tons Engine: Diesel M-40 outputting 1200hp Radio: 10-R series Crew: 6 Armor: Hull: 135/130/135 Turret: 135/135/135 Armament: 1x 107mm Zis-6 1x 45mm 20-k 3x 7.62mm DT Kreslavsky’s proposal Designers N. Dukhov (model existing ingame) and M. Kreslavskiy in their designs recommended pairing the guns in one turret, and engineer N. Shashmurin proposed mounting the 107 mm cannon in a casemate fashion in the hull on a mount with a 30-degree angle of firing to the horizon. This designer dropped the 45 mm gun and in its place mounted a 76 mm gun in a production KV-1 tank turret on an enormous hull with significantly lengthened chassis components. Specifications: (direct from Battlefield.ru’s data sheet) Length: 9m Width: 4m Height: 3.225m Ground clearance: 0.6m Combat weight: 92.6 tons Engine: Diesel M-40, 1200hp Radio: 10-R series Crew: 6 Armor: Hull: 130/125/130 Turret: 135/140/135 Armament: 1x 107mm Zis-6 3x 7.62mm DT 1x 45mm 20-K (Coaxial) Shashmurin’s proposal Specifications: (estimated size scaled to fit with KV-1’s road wheel) Length: 8.35m Width: 3.53m Height: 3.121m Ground clearance: 0.5m Combat weight: ? tons Engine: Diesel M-40, 1200hp Radio: 10-R series Crew: 6-7 Armor: Hull: 135/100/125 Turret: 60/60/60 Armament: 1x 107mm Zis-6 (casemate/ hull mounted) 2x 7.62mm DT 1x 76mm L-11 (turret) Mikhailov’s proposal Two designers, P. Mikhailov and G. Turchaninov, in their designs recommended the mounting of the 45 mm Gun casemate fashion, having cut an embrasure for it in the frontal armor plate of the tank’s hull, and they placed the 107 mm Cannon in a standard tank turret on the vehicle’s hull. Specifications: (direct from Battlefield.ru’s data sheet) Length: 9.m Width: 3.6m Height: 3.m Ground clearance: 0.5m Combat weight: 86 tons Engine: Diesel M-40, 1200hp Radio: 10-R series Crew: 5 Max fuel load: 2800 litres (located next to the engine position and half way across the turret ring) Armor: Hull: 180/150/130 Turret: 140 (conical) Armament: 1x 107mm Zis-6 2x 7.62mm DT 1x 45mm 20-K Tseits’ proposal Only engineer N. Tseits rejected the mounting of a second gun. He suggested the mounting of the 107 mm cannon in a standard tank turret, laying it out in circular form so that the entire basic load of 120 fixed rounds were stowed along the walls of the cylindrical turret. This design stood out for its originality and in the future created fertile soil for employment of an auto-loading mechanism. Specifications: (direct from Battlefield.ru’s data sheet) Length: 8.35m Width: 4.03m Height: 3.62m Ground clearance: 0.55m Continue reading →
