The Borg probe was a type of manned vessel used by the Borg Collective in the 24th century. The craft had an elongated shape. It was equipped with beam weapons that made it an equal match to a Starfleet Intrepid-class starship in terms of firepower. In addition to a crew of borg drones, the ship was also equipped with robotic auto-regeneration units. The probe had transwarp driver capability.
During 2375, the USS Voyager encountered a Borg probe that had diverted course to intercept and assimilate them. After exchanging fire with the probe, the crew of the Voyager attempted to disable the probe by beaming a photon torpedo onto it, while the probe was remodulating and regenerating its deflector shields. However, the torpedo detonated near the power core and destroyed the ship. There were no survivors. On orders from Captain Kathryn Janeway the crew conducted a salvage operation on the debris.
