The Mariner Valley shipyard was a Martian Congressional Republic Navy (MCRN) shipyard located at Mariner Valley on Mars. At this location, MCRN ships are dismantled and/or refitted.


The shipyard contains space within its dome for numerous capital ships to be maintained or stripped down. The facilities contain many stores with military equipment and parts of the dismantled vessels.


After her dishonorable discharge from the MMC (Martian Marine Corps), Bobbie Draper received a job working as a demolition technician of third-class[1] during which she worked on a Donnager-class battleship to be dismantled.[2]

While being extorted to get her nephew back, Bobbie left open a door of a store room. She waited nearby and notices that the two men to enter the store to steal from it were actually Belters disguised in MCRN uniforms of the MCRN Aryabhata.[3]
