Germany 21 cm Nebelwerfer 42

Showing the details of the shells used(where known)   Tweet Weapon Details 21 cm Nebelwerfer 42 (Rocket Launcher) History This was a five barrelled 21cm rocket projector that could fire five rockets in a sequence. The rockets were not very accurate, but provided a good volume of explosive at up to 8000 metres. This launcher could be sleeved down to fire the 15cm rockets as well as the 21cm rockets. The amount of smoke and dust thrown up by these rockets made it susceptible to counter battery fire unless moved immediately after firing.

An explosion within 9 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 23 mtr of infantry in the open will cause 33% casualties. The blast effect of this shell exploding within 1 mtr of an armoured vehicle will penetrate 7 mm of the tank armour including the roof. 15 cm Wurfgranate 41 Nebel (Smoke) 150mm 35.9Kg 342M/Sec Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.29 0.59 1.2 2.47 3.81 5.24 6.75 8.35 Penetration(mm@30°) 105 100 94 88 81 74 68 63 Penetration(mm@0°) 122 116 109 102 94 86 79 73 Hit Probability(%) 98 98 96 48 22 6 3 2 21 cm Wurfgranate 42 (HE High Explosive) 210mm 109.5Kg 320M/Sec 10.170Kg explosive Maximum Range 7800 Mtr Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.31 0.63 1.27 2.6 3.98 5.41 6.91 8.47 Direct Fire Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.31 0.63 1.27 2.6 3.98 5.41 6.91 8.47 Hit Probability(%) 98 98 93 44 22 6 3 2 Blast/Fragmentation Effects Burst radius Infantry in open 99% kill 5 mtr Burst radius Infantry in open 66% kill 10 mtr Burst radius Infantry in open 33% kill 25 mtr  Armour Penetration inc roof at 2 mtr 30 mm An explosion within 5 mtr of infantry in the open will cause 99% casualties - lethal. An explosion within 10 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 25 mtr of infantry in the open will cause 33% casualties. The blast effect of this shell exploding within 2 mtr of an armoured vehicle will penetrate 30 mm of the tank armour including the roof.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
