Trumpeter 05587 Soviet JS-1 Heavy Tank

The IS-1 is a Soviet heavy tank from the Second World War. The first prototypes of this vehicle were built in 1943, and it entered service in the same year. About 100 vehicles of this type were built during the production process. The combat weight of the tank was up to 44 tons. The drive was provided by a single W-2-100 diesel engine with a power of up to 520 HP. The main armament consisted of the 85mm D-5T gun and three 7.62mm DT machineguns.

The IS-1 vehicle (sometimes referred to as IS-85) was developed as a successor to the tanks from the KW family, especially the KW-1 vehicle. While designing it, the aim was to keep the best possible armor (especially in the front part of the car), improve traction properties and use a much stronger weapon, i.e. the 85 mm cannon instead of the 76.2 mm gun used in the KW-1. From the beginning, it was also assumed that the new tank would be designed to fight new types of German tanks, but it was also seen as a "breakthrough tank". However, the advent of the T-34/85 with the same firepower questioned the continued production of the IS-1. There was also a need to increase the firepower of the Soviet heavy tank, which in turn led to the creation of the IS-2, which was based on the IS-1.
