The SU-57B is a Soviet tank destroyer. It was introduced in Update 1.83 "Masters of the Sea".

This tank destroyer uses a 57 mm ZIS-4 for its main gun. It features a low profile, good top speed (40 km/h in RB) and great penetration for its rank, but weak armour at all angles.

The overall design of the SU-57B allows for sneaky attacks, revolving around the 57 mm ZiS-4 gun that allows for engagement from medium range on unsuspecting enemies. Because of its low profile, this TD can use bushes and terrain to hide its approach. However, the trade-off is lacklustre mobility, so it compares with the ZiS-30 that provides better mobility and speed and can reposition much faster. Despite all these limitations, when played right the SU-57B can score good scores, but only when properly positioned and not detected.
