Rheinbote
Rheinmetall developed the unguided solid fueled Rheinbote missile in 1943. In
the same year the first launch took place. The Rheinbote was the first four
stage rocket. The small (20 kg) warhead rendered this missile practically
useless, but nevertheless some 220 units were fired aginst Antwerp between
November 1944 and the end of the war.
