The Borg sphere was a huge sphere-shaped starship used by the Borg Collective, sometimes designated as a "long range tactical vessel" or as an explorer. These ships were designed for multiple mission profiles, including as a last resort contingency. (VOY episode: "Drone", ST:CCG: First Contact, Decipher RPG module: Starships)

At least one Borg Sphere had been observed to have time travel capabilities. On one such occasion, a Borg Sphere traveled back to the year 2063, in order to prevent the historical event known as First Contact. (TNG movie & novelization: Star Trek: First Contact) Although the sphere went back in time to 2063, it was intended to only return a few days into the past. (Star Trek novel: Engines of Destiny)

During Voyager's attempt to get home in 2377, they were chased by Sphere 634, one of the few the Borg Queen had managed to keep in contact with. The sphere managed to weaken Voyager inside the collapsing transwarp corridors before capturing the ship. When the sphere arrived in the Alpha Quadrant, a fleet of 27 Federation starships opened fire on the sphere. It took a transphasic torpedo fired from Voyager to defeat it. (VOY episode & novelization: Endgame)

A more heavily armored version of the Sphere was fielded by the Borg Collective circa 2379, dubbed the Borg Sphere Prime and acting as the dreadnoughts of the Collective. (TNG video game: Starfleet Command III)
