Fliegerfaust

The Fliegerfaust (lit. "pilot fist","plane fist", or "aviator fist"), also known as the "Luftfaust" (lit. "air fist"), was a German prototype of a man-portable, multi-barreled, unguided rocket launcher, designed to destroy enemy ground attack planes.
Ordered into production in the last year of World War II, only a few were made and used before the end of the war in Europe.
