A construction ship was a type of spaceship used for deploying and controlling worker bees, which operate as a team in order to construct starbases and other large-scale outpost space station facilities.
History and specifications[]
Occasionally a full-fledged starship, some constructions ships could also operate as a low-impulse vessel. They were also equipped with tractor beams. When available, the construction ships could be charged with towing disabled vessels to berth for repair.
A capture of an alien race's construction vessels could sometimes provide the captor with the technical data necessary to construct alien facilities. For example, a Federation fleet in possession of a Borg construction ship would become capable of building Borg facilities and vessels, and other technologies. This also applies when the Federation has captured other alien races' construction ships. (ST video games: Armada, Armada II)
