The PT-91 Twardy is a Polish main battle tank, which is an upgraded version of the Soviet T-72M1 tank. The first prototypes of this model were developed in 1993. The basic version of the tank was mass-produced at the Bumar-Labenda enterprise from 1995 to 2002.
The main feature of the PT-91 tank is the Twardy protection using active armor of ERAWA's own design, which has 394 blocks. They cover the front of the hull and the turret. These blocks are located almost without gaps to each other. Tests have shown that ERAWA blocks increase tank protection by 30-70% depending on the type of projectile.
