The Mars Shipyards is a huge structure in orbit of the planet Mars. They are the largest orbital drydocks in the 'continuum, operated by both the Yutanyi Corporation and the Harrow-Xeng Corporation for the production of the Shihon-Class Cruiser, among the maintenance of the Commonwealth's Naval fleet. One drydock is set aside for the production of large civilian liners that are produced in space due to their size.
