During the installation, the gun cradle cracked and needed to be fixed which delayed the production of the vehicle even further. On May 6, 1942, all the preparations were done for ground testing, the gun cradle was repaired. The test was successful and the new heavy tank was put into service as the 41.M Turán (a.k.a. Turán II or Turán 75 short). The first Turán IIs arrived to the troops in September–October 1943 because the ordered gun optics' and ammunition's production were delayed.
