Groundborer
this ancient, Akin-Dower mining vehicle was developed for quickly excavating tunnels and chambers for use on hostile planets. These excavations could then be used as living spaces for miners and other colonists, especially when the planet's atmosphere was unbreathable. The Groundborer was 120 meters in length, and required a crew of 15 to operate. Up to fifty miners or colonists could be transported inside the craft. The ancient Naddists of Onderon converted a number of Akin-Dower Groundborers for military use, adding four medium blasters to the craft and dubbing it the "Onderonian War Machine."
