The Vigilance was an Imperial-class Star Destroyer under the command of Admiral Rae Sloane during the months following the Battle of Endor. During this period the ship was encountered by Captain Wedge Antilles, a pilot for the New Republic, over Akiva. Antilles was captured by the crew of the Vigilance. He was taken to the planet's surface by Admiral Sloane, where he escaped and sent a distress signal to the New Republic. The New Republic then dispatched a fleet of five ships. In the ensuing battle, the Vigilance and a second Star Destroyer, the Ascent, were destroyed; and Admiral Sloane escaped aboard the remaining Star Destroyer, the Vanquish.
