When Jonathan Archer defied the orders of Starfleet Command in January 2155, Broadsword was one of the seven Starfleet ships that almost burned out their warp coils to race back to Earth. The hurriedly assembled fleet was led by the dreadnought ISS Imperator and consisted of two Terran destroyers and four NX-class battleships, including Broadsword.
On the orders of Fleet Admiral William Gardner, the fleet engaged the USS Defiant, a Constitution-class heavy cruiser from the 23rd century of the primary universe. Hoshi Sato had poisoned Archer and declared herself Empress of the Terran Empire.
When Defiant dove into Earth's atmosphere to target Starfleet Command in San Francisco, Gardner ordered Broadsword to engage in a suicide run. Empress Sato had Defiant fire phasers and photon torpedos at Broadsword, and the battleship's polarized hull plating failed under the onslaught. Broadsword exploded moments before crashing into Defiant. (ENT - Mirror Universe novel: Age of the Empress)
