Following the success of assault guns
on the World War II Eastern Front
, the Hungarians
developed their own model, based on the chassis of the Turán tank
. There were two designs, the 44M Zrínyi I
, incorporated a long 43M 75 mm gun, but it did not pass the prototype stage. The 40/43M Zrínyi II
was armed with a 40M 105 mm L/20 howitzer.
The Zrínyi II design was a traditional infantry support vehicle. The Zrínyi I was hoped to fulfill an anti-tank role.
Between 40 and 66 Zrínyi II units were produced between August 1943 and July 1944 and a single Zrínyi I prototype. There is only one surviving Zrínyi II in the Kubinka tank museum near Moscow.
