Second Battle of Sector 001

The Second Battle of Sector 001 was a battle fought in 2378 between the Borg Collective and the United Federation of Planets.

Prelude
In 2378, the starship USS Voyager returned to Earth from the Delta Quadrant via a Borg Transwarp Hub. A Borg sphere was sent to intercept them, but was destroyed by a transphasic torpedo acquired from the future.

After recovering from the destruction of the hub, the new Borg Queen sent a Borg cube to Earth to find out what had happened to the sphere. Recently promoted Admiral Janeway was notified, and organized a fleet to counter the threat.
