The heavy cruiser known as the Doomer, of the Dreadnaught-class heavy cruiser designation, operated as part of the Bothan defensive forces throughout the duration of the Galactic Civil War.
This cruiser was dispatched to rendezvous with the MC80 Star Cruiser named Knights, but both starships came under assault. The Doomer tried to escape the conflict, but Maarek Stele annihilated the ship.
