The T-54 Model 1951 is the third variant of the T-54 main battle tank family. Produced from 1952 to 1954, the Model 1951 replaced the fully egg-shaped turret from the Model 1949 with a new hemispherical turret. However, it features a new TSh-2-22 telescopic gunner's sight instead of the old TSh-20 telescopic gunner's sight. It also has an engine exhaust smoke system that creates a temporary smokescreen by injecting vaporized diesel fuel into the exhaust system. This feature was carried over to the T-54, T-55, and T-62 main battle tank families.

Introduced in the Closed Beta Test for Ground Forces before Update 1.41, the T-54 Model 1951 is nearly identical to the previous variant, with the addition of new high-explosive anti-tank fin-stabilized (HEATFS) ammunition capable of penetrating 380 mm of armour. However, since the post-penetration damage is insufficient, it should not be used as the primary ammunition for engagement. The playstyle is very similar to the Model 1949 variant.
