Little is known about this craft; Voyager encountered one in 2375 and found it to be a relatively small and poorly armed ship apparently designed to act as a manned probe vessel. Scans indicated that the probes armament was significantly weaker than Voyagers, and when it attempted to assimilate the Starship Captain Janeway beamed a photon torpedo onto the probe to disable it. Unfortunately, the torpedo detonated near the probes power system and it was destroyed.

Voyager recovered eight thousand metric tons of wreckage from the probe, and although most of it was too badly damaged to be of use some important tactical data was recovered. This allowed Voyager to mount an attack on a Borg scoutship, recovering a transwarp coil which ultimately allowed them to cut another twenty thousand lightyears from their journey home.
