Main Cargo Bay & Motor Pool (Deck 19)

This is the ship's largest single compartment, an enormous open bay spanning nearly the full width and length of the lowest deck, its ceiling rising two full deck heights to accommodate the tallest cargo containers and vehicles the ship carries. The forward two-thirds of the bay is given over to freight storage, marked off in a grid of numbered deck sections by painted yellow lines, with standard cargo containers stacked two and three high in some sections, secured against the deck with magnetic clamps and cargo netting where stacking height demands extra restraint. Heavy-duty overhead gantry cranes ride tracks spanning the bay's width, capable of lifting and repositioning even the heaviest containers with mechanical arms that fold neatly against the overhead when not in use. The aft third of the bay is sectioned off as the motor pool, home to a small fleet of ground vehicles used during planetary survey and away missions, several open-topped work vehicles and a pair of enclosed transports parked in marked bays, their surfaces a mix of practical matte grey and the ship's identifying hull markings. A vehicle maintenance alcove sits along the motor pool's side wall, equipped with a hydraulic lift platform and a modest parts locker for routine upkeep between missions. The deck throughout is heavy reinforced composite rated for substantial point loads, and the walls are plain industrial grey, broken by the massive segmented cargo doors visible at the bay's aft end and by numerous secondary access points along both long walls. Lighting is bright and even, provided by rows of high-output fixtures suspended from the overhead framework, casting the entire cavernous space in even white light. The air carries the mingled scent of stored cargo, machine lubricant from the motor pool, and the faint ozone tang of the gantry crane systems, and the ambient sound is a mix of distant mechanical hums, the occasional grind of a crane repositioning a container, and the vast, echoing quiet characteristic of the ship's largest enclosed space.
