A large replicator in the shuttlebay of the USS Protostar that can manufacture complete vehicles, from ground rovers to shuttlecraft, building them piece by piece on demand.
The vehicle replicator assembles a craft one component at a time and announces its progress as it works. It gives the small USS Protostar the ability to make whatever transport a mission requires rather than carrying a fixed set of shuttles.
In Prodigy it first proves its worth in Dream Catcher, producing the Runaway, the rover that Jankom Pog and the others take down to a planet's surface. In Time Amok the Diviner hacks it to build a new Drednok aboard the ship, and in A Moral Star, Part 1 it makes a copy of Zero's containment suit.
In Supernova, Part 2 it turns out a bare escape shuttle in the minutes before the Protostar is destroyed. A vehicle replicator is used again in the second season, including in Touch of Grey.
