As the sister ship of Pillar of Autumn, Dawn Under Heaven would have looked like this
The UNSC Dawn Under Heaven was a UNSC Template:ShipClass cruiser in service in 2552.
The Dawn Under Heaven was the sister ship of the UNSC Pillar of Autumn. At Reach, the Dawn Under Heaven fell to the Covenant. Before the modifications to the vessel, the ship was due to be scrapped, as the Halcyon-class was widely regarded as a joke by UNSC officers and crewmen. The refitted Dawn Under Heaven, however, was one of the most powerful ships available to the UNSC.
