The USS Fredrickson (NCC-42111) was an Excelsior-class Federation starship in service in the 24th century.
In 2371, the Fredrickson underwent a refit at the Utopia Planitia Fleet Yards in orbit of Mars. (VOY: "Relativity")
The ship was heavily damaged in one of the early battles of the Dominion War, and needed to be towed away from the battle zone. (DS9: "A Time to Stand") The Fredrickson was repaired in time to see action in Operation Return, the first major Federation and Klingon victory of the war. (DS9: "Sacrifice of Angels")
- The Fredrickson was represented by the USS Excelsior model built for VOY: "Flashback" for its first appearance. It was later rendered as a computer-generated version.
