Vigilance (Imperial-class)

The Vigilance was an Imperial-class Star Destroyer active after the Battle of Yavin leading a fleet which included Helix Squadron. Under orders from Darth Vader, the fleet participated in the Battle at Fostar Haven to destroy the Alderaanian refugee convoy. During that battle, the vessel was under the command of Commodore Rae Sloane. According to historian Beaumont Kin, the Vigilance was also present and under her command at the ambush of a rebel convoy at Derra.

For her efforts in discovering the prior whereabouts of the Millennium Falcon, Darth Vader formally awarded the ship's command to Sloane, instead of Firmus Piett's nephew as originally intended. Sloane commanded the ship at the Battle of Endor.

Later, it was still 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.
