When the New Republic under Mon Mothma approved the construction of a defensive fleet after the Battle of Endor, the technicians of the Nadiri Dockyards were asked to build a new class of battleships from captured Imperial ships. The Starhawk-class, that was intended to help with the destruction of the imperial fleet’s scattered remnants. resulted from this recycling process. Those heavy battleships could definitely take on an imperial star destroyer, although they were registered as “defensive fleet”. This became possible through unusually strong tractor beam emitter, which were able to captivate the star destroyers. They were furthermore equipped with a very powerful armament consisting of laser canons, ion torpedoes and turbolaser phalanxes.
A total of probably three of these large ships were produced and all three were involved in the battle over Jakku, during which, however, two of the three Starhawks were destroyed.
