In the middle of 1939, Edward Habich designed several projects of vehicles considering the experience of German and Soviet engineers. One of these projects involved the Horstmann suspension, 60 mm sloped armor, a small German turret, and a gun that featured high penetration and low recoil. Thus, Habich developed a vehicle that combined the features of the Pz.Kpfw.IV German medium tank and the T-34 Soviet medium tank. Development was discontinued, as Poland was invaded in 1939.
