The new weapon
was designated the Raketenpanzerbüchse ("Rocket Tank Rifle") usually
It was commonly called the Panzerschreck ("Tank Terror") and was also nicknamed Ofenrohr ("stove pipe") by the troops who used it.
Much of its design and mechanisms were very similar to the Bazooka. The major difference being it’s heavier round. The tube itself was 164cm long and weighed 9.25kgs unloaded. The round was the RPzB.Gr. 4322 (Raketenpanzerbüchsen-Granate/"Rocket Tank Rifle Grenade") with a shaped charge warhead of 660g and weighed 3.30kg. This first model was built in small number and was designated the Raketenpanzerbüchse 43.
One of its early problems was a reluctance by troops to use it, as their face was likely to be peppered with propellant particles as the rocket left the tube and continued to burn for further 2 meters.
