It housed the powerful Ion Ring, a device used to stabilize unstable atmospheres.
It was used to destroy the atmosphere of the planet Rion, and afterward was turned on Volz's homeworld of Little Kessel. Before the Ship could be used to fully destroy Kessel's already fragile atmosphere, Han Solo, Luke Skywalker and Chewbacca rescued the Professor, who reversed the flow of the ship's ion units, causing a meltdown which destroyed the ship. The four were barely able to escape with their lives.
