The T-44 was developed as the successor of the legendary T-34 tank, and although it was much superior, it retained the same 85 mm cannon. A 122 mm gun was fitted in some prototypes, but this was deemed unsatisfactory. Thus, an upgraded version was developed with the 100 mm D-10T. Testing began in October 1944 for this upgrade at the Ural Tank Factory, and different cannons were tested, like the D-10TK and the LB-1. The new armament meant a modified turret with its ring diameter increased, with increased weight and increased armour in the turret as well as armour panels in the sides. The results of the so called T-44B were excellent and the army saw a lot of potential in the design, and even though the T-44-100 didn't reach serial production, two prototypes were constructed, and the army wanted a design with the same characteristics, but more modern, reliable and versatile. Thus, the T-54 was created, and further development of the T-44 was stopped.

The T-44-100 was introduced in Update 1.57 "Battle March", and is a fast, manoeuvrable with low profile tank that should be played as a brawler, flanker, and ambusher, it's a jack of all trades. The tank's speed is quite good for its rank (compared with previous version T-34-85 and Panther variants) and its gun can compete with the 88 mm gun of the Tiger II in terms of the amount of explosive and shell velocity. However, the increased penetration and internal damage is balanced by the fact that it's slow to reload. This tank isn't suitable for front-line roles because of the lack of armour and gun depression. Moreover, the T-44-100 has a fast reverse speed, making it more of a "shoot-and-scoot" vehicle. The armour isn't very thick, however, it does have the potential to bounce some shots, however at its BR it can be easily penetrated by APDS and HEAT shells found on the MBTs that start to become more common at rank V.
