The newly finished Star Dreadnought Executor, which served as Darth Vader's flagship, began its service with the razing of Laakteen Depot. Under Vader's command, the Executor obliterated Laakteen Depot, a base that the Alliance to Restore the Republic had struggled to capture for a full year. The obliteration of the outpost functioned as the Executor's initial act. The Rebels, upon hearing reports of the destruction at their base on Yavin 4, found it necessary to create a pact with the Mon Calamari.
