The Goddard class deep space tug / repair ship is based on a design by Andrew Probert, who has worked on designs for many starships and sets for Star Trek series. Read more about the design here. Unusualsuspex on DeviantArt did a 3D model of it (image in the gallery below), and named it the U.S.S. Probert.

Here are the stats for the ship. The service date was a guess. But I also include the Spaceframe and the new Mission Profile below, in case you wish to take the Goddard class spaceframe and build it your way.
