It was formerly the USS Black Hawk (NCC-74683) and served as the flagship of the commanding admiral of Starbase Rockford for a little under a year until recalled and renamed the Trier. The reasons for the renaming was the accidental numbering of its NCC number to 74683, which belonged prior to the USS Shiloh (NCC-74683), Admiral Jeff Higdon's prior command, when Starfleet decided to honor the crew by naming a future starship the USS Shiloh (NCC-74683-A). The other reason was to free the name up to allow the Britannica to renamed the Black Hawk prior to it's assignment to Starbase Rockford. Starfleet Command deemed that the commanding admiral of such an important base, situated near the Klingon, Romulan and the Cha'ouw Empires, was important enough to send in a new and more powerful starship.
- The new NCC number and assignment has not been established in stories.
The Black Hawk was equipped with the new Type X phase cloak, allowed when the Cha'ouw government negotiated an special amendment to the Treaty of Algeron with the Romulan Empire during the Dominion War to "allow any starship, vessel or space craft listed under the operational command of Khon of the Special Cha'ouwian Imperial House K'HIg'Den, to be equipped with cloaking device/devices supplied by the Cha'ouw". This cloak (and subsequent modifications) was removed and placed aboard the new Black Hawk.
