ISS Defiant (24th century)

In the primary mirror universe, the ISS Defiant was a warship constructed by the Terran Rebellion, and was based on Defiant-class specifications stolen from Deep Space 9 in 2371. Once operational, the Defiant helped turn the tide in the war against the Klingon-Cardassian Alliance, especially at the Battle of Terok Nor, and represented a major boost to the rebels' morale.
