Comparing: T-54 ltwt. vs. T-44-100 vs. T-54 first prototype

A proposed lightweight version of the T-54 medium tank. Development was started in May 1949. Compared to its series-produced predecessor, the tank had better performance and maneuverability. Therefore, the tank was planned to replace the T-54 in accomplishing complicated missions. However, the T-54 tank of 1949 was improved and mass produced, and the lightweight version was canceled while still in the design phase.

Experimental medium tank that was developed in 1945 on the basis of the T-44 tank. Unlike the T-44 tank, the T-44-100 featured the 100 mm LB-1 gun mounted in a newly designed turret, and slat side armor. Only two vehicles were manufactured.

Developed at Factory No. 183 in 1944. It was based on the T-44, with many components modified to enhance the armor and armament of the new vehicle. According to one source, the first prototype was built at the end of 1944. However, some other sources mention another date—January 1945. The tank underwent trials in March and April 1945, but never entered mass production.
