Defiant class (DS9-537)

The Defiant class, first commissioned in 2370,[1] differed from most other Starfleet designs in many ways. It was primarily designed for military purposes, having been developed to fight the Borg, beginning in the months before the Battle of Wolf 359 in 2366. Following that incident, Lieutenant Commander Benjamin Sisko joined the development team at Utopia Planitia Fleet Yards. Besides conventional weapons, the ship had pulse phaser cannons and quantum torpedo launchers. While other ships of the class were built, the U.S.S. Defiant NX-74205 was the only Starfleet vessel equipped with a cloaking device, due to a special amendment to the Treaty of Algeron, intended to allow the Defiant to covertly gather data on the Dominion, which would then be shared with the Romulan Star Empire.[1]
