The Flame Cannon is a type of Flamer weapon that is used by the Doom Wing and the Fire Lord Daemon Engines of Chaos. These daemonically-possessed vehicles are assault aircraft that take the forms of gigantic birds of prey and are completely dedicated to the service of Tzeentch, the Chaos God of change and deceit. The Doom Wing is armed with a single Flame Cannon located under its bird skull-shaped nose and the Fire Lord is armed with two, one on each of its wings. The Flame Cannon fires deadly Warpfire, and is capable of being used to strafe ground targets and attack other aircraft.
