USS Constellation (NCC-55817)

The USS Constellation (NCC-55817) was a Federation starship that was in service with Starfleet in the mid-to-late 24th century. In 2364, this starship was commanded by Louis Rubenstein.

In that year, prior to stardate 41775, Gregory Quinn of Starfleet Operational Support Services sent an order to this ship about revised ship refit specs.

At the end of that year, Data read this order received by the Constellation from Starfleet and several others to investigate claims of a conspiracy among the highest members of Starfleet Command. 

In 2371, the Constellation was ordered to Deep Space 9 to transport a Jem'Hadar child to Starfleet for study. 

During the Dominion War, in mid-2374, it was assigned to assist the USS Defiant (2370) in the search for survivors of the Cardassian attack on the USS Honshu.
