 In later seasons, Tarrant identified the attacking pursuit ships as "the new mark fours" which appeared identical to the Starburst-class, yet apparently more advanced and maneuverable.Individually, the ships were no match for the "Liberator" which often destroyed them with a single shot from her neutron guns.However the attacking ships usually ganged up on her with plasma bolt volleys which could easily cripple "Liberator" once her power reserves ran down.
