The Fighta Bommer is the Ork's most frequently used air craft. If you look at the incredible work of the Meks, you are always amazed that it flies at all. And it does this with an unusual agility, speed and of course lots of shootas and rockits.
The Dakkajet is the Bomber's little, nimble brother. As it should be for a real Ork air craft, every free space was equipped with weaponry. What the Ork pilots lack in accuracy, the quad big shootas compensate with sheer firepower.
