A transwarp hub was a megastructure that connected the Borg Collective's galactic network of transwarp conduits. Connecting to thousands of exit apertures in all four quadrants, the hub allowed the Borg to quickly deploy vessels almost anywhere in the galaxy in minutes; giving them a decisive tactical advantage. The galaxy had six such hubs, characterized by extremely high neutrino emissions and intermittent graviton flux. The hubs were supported by interspatial manifolds, whose shielding the Borg Queen regulated from the central nexus.
In 2378, the crew of USS Voyager discovered a hub in the Delta Quadrant, inside a nebula in grid 986. While Voyager was outside of the nebula, Ensign Kim and Seven of Nine detected high neutrino emissions accompanied by an intermittent graviton flux on long range sensors, leading them to speculate that the hub was a concentration of wormholes. The nebula contained at least forty-seven Borg cubes. Collaborating with Captain Janeway's counterpart from twenty-six years in the future, who had traveled back in time to change history, the Voyager crew destroyed the hub and, with it, the entire transwarp network. Admiral Janeway had deliberately infected herself with a neurolytic pathogen and allowed the Borg Queen to assimilate her, disrupting the Queen's ability to regulate the shielding around the interspatial manifolds. Having taken the ship into one of the hub's conduits, the Voyager crew then fired transphasic torpedoes, causing a chain reaction that destroyed the entire network. Staying ahead of the resultant shock wave, Voyager exited the aperture less than a light year away from Earth before the conduit collapsed. (VOY: "Endgame")
