The Cardassian ATR-4107 was a type of advanced Cardassian weapon of mass destruction. Although officially referred to as a missile, the ATR-4107 could also be considered a completely autonomous warship in its own right. It was a warp capable vessel carrying 1,000 kilograms of matter and 1,000 kilograms of antimatter – enough to destroy a small moon. The missile also carried a large cache of conventional weaponry, including disruptors, quantum torpedoes, a thoron shock emitter and a plasma wave. On board was a sophisticated computer system that could predict and counter hostile actions, as well as life support and an operational space for a maintenance crew. The defenses are a hull of pure neutronium and heavy shields.
