Super heavy self-propelled artillery gun SU-100Y pre-war
Successful superheavy combat trials tank The T-100 in the Finnish War of 39 years, allowed the designers of the plant number 185 to think about the serial production of their offspring. Moreover, according to the decision of the military council of the North-Western Front, at the end of 39, the plant received an application for the creation of an engineering assault tank based on the super-heavy T-100.
The Finnish war showed a shortage of heavy armored vehicles, which should perform its specific tasks - transporting assault bridges, delivering explosives to the DOT of explosives or field engineers, evacuating tanks and artillery under heavy enemy fire.
During the development of an engineering assault armored tank, the designer will be given the command to install a 152-mm gun on it or something optimal for this project. The project receives the working title T-100-X. The result was a product with a wedge-shaped cabin and a 130 mm B-13 tool, which was installed on the ships of the Red Army. The design of an engineering and assault tank gradually degenerated into the creation of a self-propelled unit. Modifications of the T-100-X project led the designers to define the objectives of the new product. The project is called SU-100Y - super-heavy self-propelled installation with an arcboard.
Designers of the plant could not create two projects, and after appeals from the plant management asking them to leave one project, work continued only on the super-heavy self-propelled unit SU-100-Y.
According to some data, this project has a different name - T-100- Y.
The differences between the self-propelled unit and the T-100 tank were minimal. At first glance, the main difference is the tower part with one B-13 cannon instead of two 45 and 76.2 caliber tower cannons. At the bottom of the designers made an emergency hatch. Equipped with special hatches motor and transmission compartments for convenient field maintenance. The upper case had armor in 20 mm.
The remaining armor retained the basic configuration from the T-100 and had a thickness of 60 mm.
In addition to the tower compartment, the rest of the self-propelled unit assembly repeated assembly units from the T-100 tank. In front of the left office remained unchanged management armored vehicles.
In the stern of the hull installed aviation an engine having twelve cylinders and liquid cooling. The GAM-34-BT engine was a carburetor with a capacity of 890 hp. The transmission of the self-propelled installation has a mechanical design.
The engine was started by an electric starter "CT-70" that had a hp 15. The launch could also occur from compressed air. For cooling the engine compartment answered axial fan, which was installed on the gearbox horizontally.
In the compartment, the air came from the side holes, closed with fine nets, located in front of the engine compartment. After cooling the compartment, the hot air coming out of the engine compartment, fell on the upper part of the track.
Aviation fuel served as a fuel for self-propelled units, placed in 4-x aluminum tanks, the total capacity of which is thousands of liters 1.3.
The full tanks of the SU-100 Y super-heavy self-propelled unit were enough to overcome 210 kilometers along a good road.
The transmission is a five-speed gearbox of the main 3-x disk clutch and onboard clutches of multi-plate design with brakes of belt and single-row gearboxes in a simple and ferrodo version.
Gun B-13 model 29 of the year. Installed on the pedestal. Ammunition - 30 shells separate feed loader. The ammunition included armor-piercing and high-explosive fragmentation shells and grenades.
Torsion bar SU-100Y:
- 16 rollers 2-x sloped support version;
- 10 additional rollers with depreciation;
- two rear driving wheels;
- two front guide wheels with mechanisms for tensioning tracks;
- two small-track tracks;
The tower is made in the form of cutting under a simplified scheme. Cutting allowed the gun to have small angles of vertical and horizontal guidance (-2 to + 15 and -6 to + 6, respectively). Mechanisms for targeting guns are made by sector type. Aiming was made on the panorama of Hertz. The projectile weight of this gun in 36 kilogram did not lose armor-piercing in 40 mm at a distance of more than 4 kilometers.
To feed the loader separately, the gun had a good rate of fire at that time in 4 rpm. This rate of fire was achieved using the 2-x stroke piston valve and spring-loaded rammer.
Additional weapons - three DT machine gun caliber 7.62 mm, the total ammunition almost 2 thousands of rounds. Location - at the stern and on the sides of the self-propelled unit.
There was a complete set of equipment radio 71-TK-3 with an antenna for the production of external radio communications. Communication inside the tank went through the TPU-6 negotiators.
By the end of February 40, the armored hull was manufactured at the factory in just a couple of months after submitting an application to build an armored vehicle. And by the first of March, everything was ready for the final assembly of the self-propelled unit. Through 2 weeks, SU-100Y was assembled and even began to conduct factory tests. But they didn’t manage to send a self-propelled unit to combat trials in the war with the Finns - March 13 March 40 fighting on the Finnish front stopped. This became the point of no return for SU-100Y.
Having no combat experience, the self-propelled unit lost a place in the army to the KV-2 heavy tank. KV-2 looked better SU-100Y:
- smaller dimensions;
- less weight;
- increased armor;
- economical diesel engine.
The only minus of the KV-2 is the lower power of the M-10 howitzer of the 152.4 caliber, mm.
So KV-2 went into mass production, and the self-propelled unit SU-100Y in the middle of 40 was put on the ground near Kubinka, where 2MB stood at the start of the fighting.
Attempts by the designers of Plant No. 185 to give life to armored vehicles based on T-100 continued. In April, 40, they submit a draft tank for coastal defense. The project name is an 103 object.
According to the project, the tank had a rotating turret. An extended box was developed for it, but the dimensions of the tower did not increase compared with SU-100Y.
The armament of the coastal tank was similar to that of a self-propelled unit.
Further consideration of the project did not work, and then the war began.

Possible application in the Second World War
There is information that when the German invaders approached the capital of the USSR in November 41, they received a command to remove all workable equipment from the landfills and put them into operation to protect the capital.
According to the same data, SU-100Y became part of the so-called "separate division of heavy equipment for special purposes." It is known that before this, the self-propelled unit was put into operation. Historical documentary evidence of participation in hostilities of the only SU-100Y in 2МВ has not yet been found.
After the disappearance of the threat of taking the capital of the USSR, the equipment (single copies) was returned.
SU-100Y returned to the landfill near Kubinka, where it can be seen to this day.
