Ord Pardron sector defense outpost This sector defense outpost was a New Republic military installation on the planet Ord Pardron . Located under the surface of the planet , the outpost was originally a mining installation for the Galactic Empire , before being converted into a starfighter base used by the Alliance to Restore the Republic after Imperial forces abandoned it in 1 ABY . Starfighters from the base — known as the Ord Pardron Starfighter Base — scored numerous victories against Imperial forces during the Galactic Civil War . Following the Battle of Endor in 4 ABY and the establishment of the New Republic shortly thereafter , the base was retasked to serve as a major sector defense outpost with a full complement of starfighters , capital ships , and personnel . In 9 ABY , Imperial Grand Admiral Thrawn waged a military campaign against the New Republic . He ordered task forces of Imperial capital ships to assault several planets within the sector defense outpost ' s area of responsibility in an effort to draw military assets away from Ord Pardron . With many of its ships and fighters engaged in other systems , the base was attacked by a task force led by the " Imperial " - class Star Destroyer " Death ' s Head " . The base personnel called for reinforcements themselves , which allowed Thrawn to assault his true objective — the planet Ukio . During the assault , the base was severely damaged . Description . Built on the planet Ord Pardron , the sector defense outpost was located underground . Originally , it started its operational life as a mining outpost for the Galactic Empire until it was abandoned around 1 BBY . It was subsequently taken over by the Rebel Alliance and used as a starfighter base , but was expanded and retasked following the Battle of Endor in 4 ABY to be a major New Republic defense outpost . The base had no planetary shield , relying on the presence of heavy metals in the planet ' s crust to protect it from orbital bombardment . Occupants . As a major sector defense outpost , the base was manned by 68 , 000 personnel , and a full complement of starfighters and capital ships were stationed at the base . By 9 ABY , the outpost had enough resources available to engage Imperial forces in multiple systems across the Abrion and Dufilvian sector s . History . The Ord Pardron sector defense outpost was formally established by the New Republic following the Battle of Endor , but the base itself had been used by both the Galactic Empire and the Alliance to Restore the Republic prior to that . Over the centuries , Ord Pardron was extensively mined by the Galactic Republic and Empire for ores and minerals used in the construction of starships . Around 1 BBY , the Empire abandoned their base on the planet as they had exhausted most of the mineral resources . The Rebel Alliance took over the Imperial installation shortly before the Battle of Yavin , establishing the Ord Pardron Starfighter Base . During the Galactic Civil War , forces from the Ord Pardron Starfighter Base conducted attacks on Imperial targets , resulting in numerous successes . Imperial forces were unable to find the subterranean base to launch a counter - strike . After the Battle of Endor , the newly formed New Republic retasked the base , expanding it into a major defense outpost . Extra starfighters , capital ships , and personnel were stationed at the base , which was responsible for protecting New Republic assets in the Abrion and Dufilvian sectors . In 9 ABY , during his military campaign against the New Republic , Imperial Grand Admiral Thrawn intended to capture the planet Ukio in the Abrion sector . In order to leave it defenseless for his forces , Thrawn split his fleet into several task forces . Each force was given a target to assault , with the intention of drawing forces away from the outpost at Ord Pardron . The " Imperial " - class Star Destroyer " Bellicose " led a task force to attack Ando , which Ord Pardron responded to by dispatching a force to match them . Similar attacks at other targets , including Crondre and Filve , were launched , and again Ord Pardron deployed reinforcements to those planets . With most of its military forces away from the planet , the " Imperial " - class Star Destroyer " Death ' s Head " and its task force hit Ord Pardron directly . Ord Pardron called for reinforcements from other New Republic bases , which in turn left the planet Ukio — a major agricultural world in the Abrion sector — vulnerable . Thrawn managed to capture Ukio without much effort , while the " Death ' s Head " and her task force caused major damage to the sector defense outpost before withdrawing . Behind the scenes . The Ord Pardron sensor defense outpost was first referenced in the third book of , " The Last Command " . The history of the base was further expanded on in " The Last Command Sourcebook " published by West End Games . In 2012 , the base was referenced in " The Essential Guide to Warfare " .
