The Defector was a Galactic Civil War-era EF76 Nebulon-B escort frigate utilized by the Alliance to Restore the Republic.
Constructed by Kuat Drive Yards, the Defector measured 300 meters in length. This EF76 Nebulon-B escort frigate boasted a formidable arsenal, including twelve turbolaser batteries, twelve laser cannons, and a pair of tractor beam projectors. Typically, a crew of 854 individuals, plus sixty-six gunners, was required to operate the vessel; however, it could be run by a reduced skeleton crew of 307 beings with ten gunners. The Defector was equipped with sensors, deflector shields, and a navigation computer. Its Class 2 hyperdrive enabled faster-than-light travel, supplemented by a Class 12 backup. In atmosphere, it could reach speeds of 800 kilometers per hour. The frigate had sufficient consumables for two years of operation and a cargo capacity of 6,000 metric tons. Furthermore, it could accommodate seventy-five soldiers.
During the Galactic Civil War, the Defector served the Alliance to Restore the Republic as part of the Trax Sector Force. Around the year 0 ABY, it participated in the battle of Bissillirus, fighting alongside the DP20 frigates Corellian Thunder (Corellian Thunder) and Dream Runner.
