Wz. 64GC Bzyg

In the 1960s, the Polish military became interested in Soviet developments for equipping tanks with deep-rifled guns with a higher muzzle velocity. This Polish project proposed a classic heavy tank design with a welded hull and turret, a radar rangefinder, and a turret-controlled AA gun. A standard 122 mm gun was included as a fallback option. Deep-rifled guns were soon deemed unpromising, and Poland, following the U.S.S.R., discontinued all work on the guns, as well as on the project for the heavy tank, which remained in blueprints.
