Liberty / Legends The Liberty was an MC80 Star Cruiser that served in the Alliance Fleet during the Galactic Civil War . It was the namesake of the " Liberty " type subclass . During the Battle of Endor , the " Liberty " was the first Rebel ship destroyed by the second Death Star battlestation . History . The " Liberty " was due to be the original recipient of the Death Star plans according to Operation Skyhook ; however , the sudden appearance of the " Imperial " - class Star Destroyer " Immortal " caused the transfer of the plans from the " Tantive IV " to stop . Keyan Farlander and Hamo Blastwell , in R - 22 Spearheads , helped two X - wings from the " Liberty " fight off the Imperial forces while both ships escaped and the corvette moved to Tatooine . Shortly after the Battle of Hoth , the " Liberty " was one of the most active cruisers in the Rebel fleet . Under the command of Admiral Yamarus , the cruiser and its task force repeatedly led raids and " hit and run " strikes against Imperial facilities and warships . When information came to light on a series of raids being carried against civilian merchants in the Vilonis sector , the " Liberty " was sent to investigate . Operating alone , it uncovered details about a series of Imperial experimental starfighters and proceeded to shut the TIE Experimental Project down . At this stage , her Tactical Officer was Commander Kupalo , an Imperial double - agent . At some point , it also was instrumental in setting up a mutual cargo - retrieval operation with Dunari as well as destroying a pirate group , the Hurrim . The " Liberty " became a famous Rebel warship during its service in the Airam sector , wherein , with Rogue Squadron aboard , it destroyed the " Executor " - class Star Dreadnought " Vengeance " . It also participated in the recovery of Imperial defector Commander Zaletta , who played a key role in acquiring the second Death Star plans , and later served as the " Liberty " ' s tactical officer . Rebel pilot Ace Azzameen served aboard the cruiser for much of the period leading up to the Battle of Endor . Azzameen was famous for flying in the strike team responsible for the capture of the shuttle " Tydirium " and was possibly part of Lando Calrissian ' s crew — possibly a gunner — on the " Millennium Falcon " during the battle . Following the discovery of the second Death Star , the " Liberty " was recalled to the main Alliance fleet in preparation for the Battle of Endor in 4 ABY . The " Liberty " was lost during the battle , gaining the dubious distinction of being the first ship destroyed by the new Death Star ' s superlaser . Behind the scenes . Because of her frequent appearances in video game s ( such as Azzameen ' s headquarters ) , the " Liberty " is one of the more commonly known Mon Calamari Cruisers . The exact designation and specifications of this vessel are still matters of speculation , since the frequent appearances of Mon Cal Cruisers in books , games , films , and supplemental materials are rarely consistent . The " Liberty " has lent its name to a visual layout of the Mon Cal Star Cruiser , in that any subsequent winged cruiser of approximately 1200 meters length is classified as a MC80 " Liberty " type Star Cruiser .
