Borg assembly matrix

The Borg Assembly Matrix was a type of shipyard class made and used by the Borg Collective.

The structure possessed two separate bays; one of which was used for the construction of starships while the other was used for repairing as well as recrewing vessels. It possessed no weapons and needed to be defended by either starships or base defenses. The structure could produce the Borg Sphere, Borg Interceptor, Borg Wedge, Borg Harbinger, Borg Colony Ship and Borg Assimilator class vessels.
