The battle experiences of 1941 made Hungary realize that the 40.M Turán which was still under development and construction would not meet the expectations of modern medium tanks. While the Turán I was still under modifications the General Staff of the Hungarian Army changed the second order of 309 medium tanks to 87 medium and 222 heavy tanks armed with a 75mm gun which was later changed to 55 medium and 254 heavy tanks in 1941. The General Staff also declared that the new heavy tank must be made out from the already produced Turáns without the modifications of the engine and the weight of the new tank must be equal or close to the heavy tank.
