The Nebelwerfer (German for "fog launcher", a code name to obscure the real nature of the weapon) was a German towed rocket artillery piece, developed in the 1930s and used in World War II against light infantry targets. It had six 150 mm barrels, from which it fired rockets; a full salvo spread over a period of ten seconds. The loud screeching noise of the rounds led U.S. soldiers in the Sicily campaign to nickname the gun the "Screaming Mimi", and "Moaning Minnie".
