The Borg Probe is the smallest Borg vessel known at a length of under 200 meters. Despite its small size, the drones will try to assimilate larger vessels.

The Probe is equipped with all the standard Borg technology, transwarp drive and weapons. If the ship is damaged, all the vital systems are programmed to self-destruct so that its technology is not taken by other species.

In 2374 a Probe was destroyed by Voyager when a torpedo was beamed inside the ship near a power source.

The Probe is based off a design made by John Eaves for the Borg ship in Star Trek: First Contact.
