The Fearless was one of the ships that received Kosinski's experimental warp drive upgrades in 2364. The engineering staff reported a measurable increase in performance and engine efficiency following the upgrade. It was later suggested that these enhancements in performance may have been attributed to straightening out simple engine inefficiencies experienced by the older ship.
In 2367, the Fearless was on a planetary mapping mission in the Beta Mahoga system. The ship was named on the chart "Starfleet Operations-Sectors 21166-23079" on the Enterprise-D's bridge. (TNG: "Brothers" okudagram)
In 2369, the Fearless was on a planetary mapping mission in the Beta Cygni system. The ship was named on the chart "Starfleet Operations-Sectors 21538-23079" in the Enterprise-D observation lounge. (TNG: "Chain of Command, Part I" okudagram)

Script notes regarding the side by side with the Enterprise-D describe: "The two Federation starships come slowly together. Here, next to the smaller vessel, the size of the new Enterprise is breathtaking."
