The 30 cm Raketenwerfer 56 was a German multiple rocket launcher used in the Second World War.

Just as the Chemical Corps had responsibility for poison gas and smoke weapons that were used instead to deliver high-explosives during the war so did the Nebeltruppen.

Its 30 cm Wurfkörper 42 Spreng (Explosive missile) rocket was spin-stabilized and electrically-fired.

The rockets had a prominent exhaust trail that kicked up a lot of debris, so the crew had to seek shelter before firing.

This meant that they were easily located and had to displace quickly to avoid counter-battery fire.
