Admiral Janeway was in command of Voyager during the return of the rogue Vulcan scientist T'Uerell and her Borg forces. Janeway confronted T'Uerell alongside Captain Jean-Luc Picard of the USS Enterprise-E. As Picard took command of the fleet to oppose T'Uerell, Janeway left, assuring him that she would be back with some friends.
After T'Uerell's failed attack on Bajor and Deep Space 9, Janeway's reinforcements joined with Picard's fleet, and that of the Klingons and the Romulans. The combined fleet pursued T'Uerell to a nebula where they finally defeated her. (ST video game: Legacy)
During the Borg Invasion of 2381, Voyager was one of the vessels able to be reallocated to an allied fleet to reinforce the position of the USS Enterprise-E and the USS Aventine at the Azure Nebula. While the Enterprise and Aventine traversed subspace tunnels, hoping to find the Borg launching area, Captain Chakotay and Voyager remained in command of the fleet, overseeing efforts to open other tunnels. However, from an allied fleet of over 300, Voyager was the only ship to survive the Borg invasion force of over 7000 Borg cubes from the subspace tunnel within the nebula, and was able to emit a distress call to Starfleet Command. (ST - Destiny novel: Mere Mortals) While the ship was intact, it had its port warp nacelle sheared from its pylon by a grazing collision with a Borg Cube and was drifting in space. The Voyager crew were attempting to salvage material from the battle site to rebuild the nacelle before joining the USS Enterprise-E and the USS Aventine on their search for the source of the Borg invasion.

After the Borg Invasion of 2381, Voyager was refitted with a Quantum slipstream drive and made the flagship of Project Full Circle. Chakotay resigned after the Borg invasion and the ship was placed under the command of Captain Afsarah Eden. One of the first missions after getting into the Delta Quadrant would be to meet up with B'Elanna and Miral Paris, who had faked their own deaths. (VOY novel: Full Circle)
