During the years in the Delta Quadrant, the ship is augmented with custom, non-spec upgrades and modifications, some of which are modified from technology of other cultures, an example being Seven of Nine's alcoves and the Delta Flyer which both utilize modified Borg technology. Several pieces of technology from the future were also installed in the final episode, courtesy of Admiral Janeway who went back in time to bring "Voyager" home. Some of the adaptive solutions are to compensate for the disadvantages of being 70,000 light-years from port, such as the airponics bay and the transformation of the Captain's dining room to a galley, and the acquisition of enhancements from aliens in the Void that massively increases replicator efficiency.
