Unusual Roscii tanks and the Soviet Union. Hard positional tank T-30

History languid tank production of the USSR began in 1929 with the adoption of programs from re avtrobronetankovyh parts of the Red Army. If the tank park of our country by the number of light and medium tanks was more or less staffed, the languid tanks capable of producing profound break the enemy's defense, yet was not. Trophy languid British tanks Mk V occupied during the fighting of the war civilian clothes, were due to deterioration in the Non-Applicability for fighting the state and by the time the moral and technical levels have become obsolete. Drawing attention to the experience of leading tankostroitelnyh powers, which by that time already had such type of machines, the Soviet Government has set the Russian engineers and designers to create a puzzle and make a batch creation languid tanks breakthrough. The main requirements for modern machine were: reliable, booking more than 30 mm, the installation of weapons obmyslennoy layout scheme, which consisted of 2-or 3-guns (2-76.2 — mm and a 37 — mm) and four 7.62-mm machine guns, providing a higher volume of fire, the speed of 25 km per hour, increased stroke in store. Strength of the chassis and its ease of maintenance. In 1930 — 1933 years, in parallel with the Soviet Union were the development of several projects languid position tanks. One of these tanks had to be tank T-30, the development of which was entrusted to the Development Department of the plant "Bolshevik."

Unusual Roscii tanks and the Soviet Union.  Heavy  positional battle tank T-30

Work on the creation of languid breakthrough tank, project received the title — "T-30" (not to be confused with the project of a light tank T-30, developed on the basis of the T-40 and released a small batch in August-December 1941goda) began in December 1930 and early 1932 were made drawings and designed the layout design of a future car, was also built wood model of the tank. Outside, it was the tank with the traditional arrangement of the main layout of nodes, but the corresponding feature was the placement of weapons. It was located in a 2-towers, one above the other, at the bottom of the tower, the most anticipated set on the cross section is 76.2 mm gun CT, in coming up with a substitute for the PS-3 design engineer Syachintova and two armored 7.62 mm machine gun DT -29. The upper tower is smaller in diameter, armed with Tank 37 — 6K mm gun or PS-2 and one, just 7.62 — mm machine gun. Such a scheme of two-placement of weapons allowed the crew to "lead" and hit two targets at once, or, depending on the nature of the chosen target, use one of the guns. Just had a commander's cupola, placed on the roof of a small tower. From the machine features the third instrument was decided to abandon due to the fact that this has led to an increase in the total weight of the tank, which estimated the designers had to make more than 50 tons, which, in turn, inevitably led to the need for configuration of the chassis design, which has not been calculated more weight on the machine. Book your car was not sufficient that it were possible to reduce it to lower the weight of the tank, it was 50 mm front and 30 mm board. By 1932, the year taking into account the increased ability to rapidly growing anti-tank artillery, it was already obvious enough for the position of the tank. As the power plant to the tank it was decided to establish a V-type, 12-cylinder aircraft engine BMW-VI 500 hp or BMW-VIz 750 hp which then planned change made on the basis of his Russian M-17 engine, manufactured at the Rybinsk Aviation Plant.

The design speed should have been more than 25 km per hour. Running the machine on board, was a five trucks with 2 road wheels, 5 support rollers, idler and driving (rear) wheel. But by the end of 1932, the technical requirements for this type of machines is significantly changed, translate those requirements under project "T-30" did not seem entirely plausible and, ultimately, by the decision of the commission UMM RKKA subsequent work on the T-30 have been frozen, machine was recognized as futile and unsuccessful. All subsequent efforts to develop a languid tanks in the Soviet Union were focused on projects TG-1 and T-35, which had, according to the views of the Commission UMM RKKA, more successful and promising design. Although the T-30 has remained an unfinished project, yet he remained in the history of Russian tank design as one of the first attempts of Russian engineers and designers to position tank protivosnaryadnym with a good book and a superior firepower.
