It was rumored that Kuat Drive Yards would sell the frigates to interested third parties through secret fronts so as to not upset the Imperial Starfleet. The Rebels were not the only ones beyond the Empire to acquire Nebulon-B frigates. In small, shorthanded Rebel task forces, Nebulon-B frigates often served as the command ship. Escort frigates were used as long-range scouts, search and rescue ships, or to relay information to command ships during battle. However, the Rebels were able to find other uses for the ships which took advantage of their sophisticated sensors and deep-space multifrequency antennas. The Nebulon-B was originally designed to protect Imperial convoys against Rebel starfighters. Varying configurations could carry starfighters, albeit small quantities.

Standard Nebulon-B frigates were armed with twelve turbolaser batteries, twelve laser cannons, and two tractor beam projectors. They were eventually used extensively by both sides in the Galactic Civil War, as the Rebel Alliance also acquired a number of these ships through defection, capturing them in battle, or by outright theft.Д®scort frigates were often used to support larger capital ships, such as Imperator-class Star Destroyers and rebel Mon Calamari Star Cruisers.

The EF76 Nebulon-B escort frigate was a 300 meter-long warship that was built by Kuat Drive Yards for use by the Imperial Navy, to protect convoys from Rebel starfighter actions.
