TG, «Tank Grotte» (sometimes there are designations of TG-1 and "Tank Grotto") - experimental Soviet medium tank (because of the powerful weapons in the documents of the time often took place as "a powerful medium tank"), created 1931 , under the leadership who worked at that time in the USSR the German design engineer Edward Grothe.

The serial production of TG was not a dense forest, so in the design of this war machine includes a variety of complex assemblies, to which the issue was not Soviet industry ready. AT 1931 g. the factory "Bolshevik" in Leningrad was made only copy Grotte tank, whose design is also significantly different from the original project.

It should be noted, that the triglycerides design of the tank contained a number of innovative ideas, far ahead of his time. Some of these ideas have been implemented later in the construction of other models of tanks. In appearance tank Grotte more like a fighting machine 40s., than tanks 30s. TG refers to the average tank type. Housing TG has been completely welded, that for the period of military equipment seemed innovation. Housing in the bow was chamfered, bronelisty installed obliquely. Box turret was faired, and two mounted one above the other towers were able to provide a circular firing two guns caliber 76 and 37 mm.

Battlefield surveillance a driver drove through three windows with observation slits, and the commander used mounted on a small roof tower strobe. The design of the gearbox, which had a four speed back and forth, used gear with chevron jamming. A special reverser allows tank to move forward and backward at the same speed. Chassis tank was half covered broneekranami. There were five large road wheels on board with individual suspension, equipped with pneumatic shock absorbers.

The caterpillar was made of pressed parts and has a high resistance to rupture. Road wheels have brakes for an emergency stop in the event of breakage caterpillar. At TG were higher firepower, good security and mobility, as well as a smooth ride and comfortable seating crew. However, in the manufacture of a single model TG large under-turret overhead undergone deformation, resulting in lower rotating tower became fixed. During assembly of the combat vehicle armored compact air-cooled engine power 250 l. from., developed Grotte, has been replaced by more reliable heavy aircraft engine M-6.
In late June, 1931 g. the first test of TG, as a result of which have been identified as the dignity, and numerous shortcomings of this model.

Although Grotte tank was able to develop an impressive rate, had considerable agility and maneuverability, the reliability of this war machine was not very high. The pneumatic control servo seals tires of low quality has been used, whereby actuators are often out of order. Caterpillars were not sufficiently effective in cohesive soils, fighting compartment was cramped, and a service suspension revealed unexpected complexity.

However, it should be noted, Grotte that although the tank was not put into mass production and put into service, during work on a single model of this war machine has accumulated experience, that Soviet engineers used to develop towered T-28, T-35 and certain other.
