The USS Fearless was a Federation Defiant-class escort active from the late 24th through early 25th centuries. The Fearless was part of the first production run of Defiant-class starships. In the early 2400s the Fearless was assigned to Starfleet Academy as a training vessel. Kanril Eleya spent time aboard while attending the Academy.
