Gigantic 32nd-century Breen warship, flagship of Primarch Ruhn and later of Moll in the race for the Progenitors' technology.
The Breen dreadnought was a gigantic warship of the 32nd-century Breen Imperium and one of the largest vessels faced by the crew of Discovery-A. It served as the flagship of Primarch Ruhn during the hunt for the technology of the Progenitors.
After the clash at the Eternal Archive, Moll killed Ruhn and took command of the dreadnought with the support of its Breen soldiers. In Lagrange Point, Burnham's team infiltrated the ship and Discovery-A breached its shuttlebay, blowing the captured Progenitor structure out into space and wrecking Moll's plans.
