USS Ghost
From Star Trek: Theurgy Wiki
The USS Ghost was an early Starfleet carrier in operation at some time prior to the 2380's. Lieutenant (junior grade) Alessia Garcia mentioned it when comparing her old commanding officer Captain Marcus Alexander Slayton to one of the early generation of carrier captains.
(So far it has not been revealed exactly when the USS Ghost served or whether or not it was operated by Federation Starfleet or the United Earth Starfleet of the 22nd century.
Alessia Garcia described the uniforms worn during the time of the Ghost’s service as "those nonsensical uniforms back in the day," so the carrier was not a 23rd century design that saw service during the Dominion War. Since the Ghost would have to be a historically noteworthy vessel, it is likely that it was either a 23rd century carrier that saw action during the Federation-Klingon War of the 2250’s or a 22nd century space carrier that operated during the Earth-Romulan War.)
