The Dreadnought Missile
was a large starship sized weapon created by the Cardassian Union
The vessel essentially serves as a long range missile that carries a thousand kilograms of anti-matter allowing it the destructive capability of destroying a small moon. It is unmanned and makes use of a sophisticated Cardassian automated system that makes it independent once deployed.
