The Citadel-class shared some design features with the BTL Y-wing starfighter, which was considered a sister ship.[3] It was extremely sturdy, and could take severe punishment and still get to its destination. It was designed for a group of people who wanted a starship, but could not afford a capital ship.[1]
Due to their sturdy construction, these ships stayed in use for a long time and were transferred to many different owners.[2] They were used as luxury yachts[1] and as warships for the Rebels,[2] freebooters, the Corporate Sector Authority,[2] and pirates.[1] This led to many of them having a jumble of various features; such as smuggling compartments, military add-ons, and luxury furnishings.[2] They had two docking clamps to carry starfighters for additional protection and firepower.[1]
