USS Horizon

Starfleet ship that the Consolationprize rendezvoused with so that Carr could transport Admiral Cooper to the USS Secondprize for an inspection tour. ("Choice Blend" [TRK]) Presumably the second ship to bear the name Horizon, as the first one, a Daedalus Class vessel from the 22nd century, would have been very, very, very old at the time of this story.
