The Overlord-class command cruiser was a clear attempt by imperial high command to carry the design philosophy of their far larger Imperial-class star destroyers down to the smaller ships in the fleet, and functioned effectively as a "star destroyer with training wheels" for crew and captains on track to assignment aboard one of the larger destroyers. The Overlord and her sistership, the Omen-Class Interdictor with which she was designed, were a direct response to the rebel alliance and their success with small fighters using hit and run tactics. The Overlord was designed to be the core of anti-fighter battle groups that comprised of the command cruiser, a single Omen-class Interdictor and a pair of Raider-class corvettes, who could effectively and quickly seek out and destroy or capture the enemy ships that would normally be able to retreat from larger battle groups. These groups were often operated in conjunction with imperial special forces to capture and interrogate alliance pilots and would operate largely independent of the standard imperial command structure, far from the core where the alliance and other disreputables preferred to operate . Due to the similarity to the superstructure of a standard Imperial-class star destroyer, the Overlord could operate using many of the same tactics (although scaled down significantly) and was often referred to by admirals in the high command as a "pocket" star destroyer. Her armament was suited primarily for anti-fighter duty, with 8, 8 barrel heavy laser cannons in place of the barbette turbolaser batteries found on her much larger sibling. These weapons, along with multiple, modular weapon systems hidden beneath slide-away panels across the ships hull, allowed the Overlord to make short work of all but the most durable craft fielded by the alliance. The first of the battlegroups in which the Overlord saw action became operational in the Aturi cluster shortly after the battle of Yavin and underwent trails in that sector.
New big ship to throw at my squadron!
