This paper model is a Soviet A-44 (T-44), a medium tank first produced near the end of the World War II by the Soviet Union, from the World of Tanks game, the papercraft is created by WarGaming, and the scale is in 1:50.
The T-44 was the successor to the T-34, offering improved ride and cross-country performance and much greater armor. Designed to be equipped with a powerful 85 mm main gun, by the time it was fully tested the T-34 had also moved to this weapon. Both tanks offered similar performance, so introducing the T-44 was not considered as important as increasing T-34 production. Fewer than 2,000 T-44s were built, compared to about 84,000 T-34s. Although the T-44 was available by the end of the war, they were not used in combat.
Attempts were made to improve the T-44's armament with a new 122 mm gun, but the turret proved very cramped and the rate of fire was poor, on the order of three rounds per minute. Another attempt with a 100 mm gun seemed more promising although a number of additional changes would be needed to make a truly effective design. Design work on a slightly enlarged version of the T-44 began during the war and a prototype was produced in 1945. This newer design entered production in 1947 as the T-54/55 series of medium tanks, the most-produced tank of all time. For further information please click here.
