The Fearless was commissioned in 2292. (Star Trek: Shadowstar Station: "Dhalang"). Starfleet held a tactical simulation, Exercise Vermilion Victorious, on the surface of Beta Miranda V in March, 2301. Among the ships and stations that sent teams to participate were USS Ajax, USS Diponegoro, Fearless, USS Pandora, Shadowstar Station, Starbase 10 and T’Varian.
The Fearless was Michael Owens's first assignment out of Starfleet Academy. He became flight controller in 2356 at which time the starship and its crew had garnered a reputation as being one of the best in the fleet. A posting on the Fearless was considered a great honor and a guarantee to be part of great discoveries.
In 2361 Fearless discovered the planet Tenaria during a deep space survey mission. Lieutenant Owens was chosen to stay behind to cultivate relations with the cordial Tenarians. (The Star Eagle Adventures)
Richard D. James was assigned to Fearless as the lead flight controller in 2362. He would transfer off of Fearless to the USS Venture in 2366. James would eventually be transferred back to Fearless as a lieutenant commander and Chief Operations Officer in 2370. (Star Trek: The Quarterdeck Breed: "The Sacrifice of Agamemnon")
Fearless was commanded by Captain B. J. Simpson from at least 2370. Fearless served within Starfleet's Exploration Command. Executive Officer Lieutenant Commander Richard D. James transferred from the Fearless to serve as executive officer of the Apollo-class USS Agamemnon on Stardate 53441.4. (Star Trek: The Quarterdeck Breed: "Agamemnon")
