UNSC Adriatic

The UNSC Adriatic was a United Nations Space Command Frigate.

It is featured as part of the preloaded Halo 3 concept art in the Halo 3 Zune, although it's name can not be definitively known. This ship could be one of the three seen in The Storm. Even though all the ships were named "Forward Unto Dawn", this mearly meant that Bungie only created one Frigate model.
