Semovente
da 20/70 Quadruplo
History & Development
The need
for anti-aircraft self-propelled became obvious already after the first two
years of conflict for Italian army. The idea which could seem simple, is to
install a turret with four gun Isotta Fraschini 20 mm on a tank M hull. The
studies continued throughout 1942 and in early March of 1943, Tests have given
excellent results. After the armistice, germans confiscated the prototype.
