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 its name can not be definitively known. This ship could possibly the third Frigate in the end cutscene of the level The Storm in Halo 3 alongside the Aegis Fate and the Forward Unto Dawn.
