Frequently Asked Questions

What was the wz.35 antitank rifle?

The wz.35 was Poland's standard antitank rifle at the start of World War II, designed by Józef Maroszek. It utilized a bolt-action mechanism and a high-velocity 7.92x107mm DS cartridge to penetrate early armor.

What made the wz.35 antitank rifle effective?

Its effectiveness stemmed from the high muzzle velocity (4,200 fps) of its specialized 7.92x107mm DS ammunition, allowing it to defeat up to 20mm of armor plate at 100 yards through kinetic energy transfer.

What were the challenges in the wz.35's development?

Early challenges included significant barrel corrosion leading to short barrel life (60-70 rounds). This was later improved with a new powder formulation and an extended 107mm case, increasing barrel life to 250-300 rounds.

How was the wz.35 deployed and used?

The rifle's existence was kept secret, with deployment orders issued just days before the German invasion. After Poland's fall, Germany captured many, designating them PzB 35(p), and some were supplied to Finland.
