The Flaming Onion,Utilized by the Germans during World War I, “the flaming onion”, aka “lichtspucker” (lightsplitter), was a specialty gatling gun modified as a flare gun. Unlike a regular 37mm revolving cannon, the flaming onion was a smoothbore that could fire flares only.  They were used to fire five round bursts of flares over enemy trenches in order to facilitate night assaults. However, they were also used as anti aircraft guns, as the flares could easily set alight a canvas covered aircraft. -- source link
