It was capable of defeating any contemporary tank at long range, excluding the Tiger II : to destroy that heavy tank the gun needed to shoot at less than 1,600 m (5,200 ft) from the target. The gun was capable of defeating the turret of Tiger II at a range of 800–1,000 m (2,600–3,300 ft). The gun was also used as a field gun.
