Historical Reference:
This vehicle was developed for infantry support and had increased firepower thanks to a double-barreled gun system. It was based on proven solutions and maximum unification. A densely packed chassis and compact engine-transmission compartment allowed for mounting a strong turret, making it possible to arm the tank with two high-caliber guns and significantly increase gun traverse limits. Cast elements of variable thickness were used extensively in construction, reducing the weight; however, because of the need for enhanced protection, mounted armor parts were used, forming a spaced barrier against HEAT shells. The concept turned out too unusual and was not accepted by customers.
