The Jefferson was launched alongside the USS Pathfinder in 2374, shortly before Operation Return.
During the Second Battle of Chin'toka in 2375, the Breen fired their energy dampening weapon at the Jefferson, draining its energy. The ship soon lost weapons, shields, propulsion and targeting scanners. After taking numerous hull breaches, the ship's warp nacelles were torn off the pylons by Breen weapons. One of their torpedoes also hit the bridge, destroying deck 1 completely.
After the main deflector and engineering were destroyed, Breen torpedoes tore the ship apart in three large sections. The first was the saucer section, the second one was the stardrive section and the third one were the shuttlebay and pylons.
