In the year 2373, the Budapest fought against the second Borg invasion at the Battle of Sector 001. (TNG movie: Star Trek: First Contact) Just before the battle, the Budapest was one of five test-bed starships using the the new TR-116 rifles. After the ship was boarded by the Borg, Sam Bowers and other crewmembers used the TR-116 rifles against the drones, killing many of them. Several Budapest crewmembers were assimilated including the commanding officer, Captain sh'Raazn. Although the death toll was high, the Borg were defeated. (DS9 - Mission Gamma novel: Lesser Evil)
