Construction ship

According to the gameplay of Star Trek Armada II, the Federation construction ship was a low-impulse vessel used for deploying and controlling worker bees, which operated as a team in order to construct Starbases and other large-scale facilities. They were also equipped with tractor beams. When available in excess, the construction ships were charged with towing disabled vessels to berth for repair.

Also, as featured in STA2, the capture of an alien race's construction vessels would provide its captor with the technical data necessary to construct alien facilities. By doing so, one race could ascend another's in-game tech tree; so that a Federation fleet in possession of a Borg construction ship, would become capable of building Borg facilities and vessels, and other technologies.
