Kotin, designed at first an all-welded hull with cast turret and large parts, with wide, reinforced tracks and a torsion-bar suspension.

The TsKB-2 design bureau responsible for the SMK, through chief engineer Zh. During these operations, the two KV prototypes outperformed the others and the type was subsequently approved for a 50-unit pre-series under the name of KV-1. Another prototype however, the KV, had been drawn by the same team which designed the SMK, as a single-turreted variant. They were also costly, over-complicated and difficult to maintain. They proved resistant, but showed very poor reliability and mobility. All three were tested in operations in Finland during the “Winter War” (September-December 1939). This was a true monster, influenced by the multi-turreted fad which came from Great Britain, but was quite complicated and unsatisfactory in operations.Ī new 1937 specification gave birth to the two T-100s and the unique SMK prototype, showing a new arrangement of firepower, with tandem turrets.

Hello dear reader! This article is in need of some care and attention and may contain errors or inaccuracies. Protection was therefore given priority over mobility. They were to be placed on key tactical positions to drag and concentrate enemy fire, or destroy enemy fortified positions while assisting infantry. The latter were also also called “siege tanks” and had to be able to resist most AT gun calibers, either deployed by enemy infantry or other tanks, and to destroy them as well. The tactical deep battle doctrine advocated for fast battle tanks ( BT series and T-26), reconnaissance types ( T-27, T-37A, T-38 tanks and tankettes) and medium or heavy penetration tanks (“Tyazholy”). The concept of “deep battle”, which contained the doctrinal use of the Soviet heavy tank, was first theorized during the late twenties, then refined and eventually adopted by the Red Army Field Regulations in 1936.
