As a safety precaution, the built-in fuse for the warhead is released by a safety mechanism. This arms the warhead after a flight distance of approximately five meters. Once armed, the warhead will detonate on impact, and as a safety when the rocket's propellant runs out. This safeguards against live ammunition staying around and causing hazards to all in the future. The Panzerfaust 3 is distributed in a special package including spare parts and a cleaning kit. The package contains a launcher, ejector and spring, extractor, dummy extractor plug, bolt-head retaining pin, plastic cleaning rod with brass tip, bore and chamber brushes, camel's hair brush and a prismatic bore scope. It takes several minutes to assemble and load the launcher.
