In late 1944 the decision was made to develop a short-range infantry anti-tank weapon based on the German Panzerfaust but reloadable. This weapon should be light with a hollow-charge warhead giving a minimum penetration of 120 mm.

In 1945 three test versions with different position of the firing mechanism and different barrel diameter were built. All had a conical extension with a length of 380 mm at the rear end to minimize the recoil. All used an experimental grenade with a length of 800 mm, 2,3 kg weight, propellant charge of 35 g and an explosive weight of 500g.


Version 1 had a barrel length of 600 mm and. With a barrel diameter of 45 mm the maximum penetration was 100 mm.

Version 2 had a barrel length of 1000 mm. With a diameter of 57 mm the maximum penetration was 110 mm.

Version 3 had a barrel length of 1000 mm. With a diameter of 45 mm the maximum penetration was 110 mm.

The decision was made to continue development of version 3. The final version had a weight of 6,4 kg, a barrel length of 1000 mm and the 380 mm long conical rear extension.


Different types of rocket propelled grenades were tested with propellant charges of between 30 g and 100 g. The explosive weight was increased to 625 g, the total weight was still 2,3 kg.

The final version had total length of 850 mm with a propellant part of 180 mm length, a propellant weight of 100 g, a 520 mm guidance stick with an impact fuse on top and a warhead of 150 mm with an explosive weight of 625 g. Muzzle velocity was 40 m/sec., minimum range 50 m, maximum range 150 m, penetration 120 mm.
