Published on August 26, 2024
Duration: 23:37

The wz.35 was Poland's innovative antitank rifle, developed by Józef Maroszek, achieving extreme muzzle velocity (4,200 fps) with a high-pressure 7.92x107mm cartridge to penetrate 20mm armor. Despite initial barrel life issues, improvements led to practical field use. Kept secret, it saw limited deployment before WWII and was later used by German and Italian forces.

Quick Summary

Poland's wz.35 antitank rifle achieved extreme muzzle velocity (4,200 fps) using a 7.92x107mm cartridge to penetrate 20mm armor at 100 yards. Despite initial barrel life issues, it was a potent, albeit secretly deployed, weapon that saw post-war use by German and Italian forces.

Frequently Asked Questions

What was the primary design principle behind Poland's wz.35 antitank rifle?

The wz.35 antitank rifle was designed to achieve extreme muzzle velocity, around 4,200 feet per second, rather than relying on complex armor-piercing projectiles. This high velocity allowed its kinetic energy to penetrate armor.

How effective was the wz.35 antitank rifle against armor?

At 100 yards, the wz.35 could penetrate 20mm of armor plate. The impact would vaporize the lead bullet and knock a one-inch diameter plug of armor into the vehicle's interior.

What were the initial challenges with the wz.35's barrel life?

Initial barrel life was a significant issue, lasting only 60-70 rounds due to corrosion. This was later improved with a new powder formulation and an extended case, increasing barrel life to 250-300 rounds.

How was the wz.35 antitank rifle deployed and used after its production?

The wz.35 was kept secret and deployed just before WWII. After Poland's fall, Germany captured many, designating them PzB 35(p), and used them, with some also sold to Finland.
