By 2368, the B-24-CLN had been assigned to the Surplus Depot Z15 in orbit of Qualor II in Sector 213. The facility was responsible for storing the hulls and salvaging useful components from such decommissioned vessels.
The ship had a typical Federation starship hull structure, comprised of a saucer section primary hull, and a triangular aft secondary hull, with two connected warp nacelles. The aft end of the triangular secondary hull featured the ship's shuttlebay. (TNG: "Unification I")
The model used for B-24-CLN was one of the refit USS Enterprise concepts designed by Ken Adam and Ralph McQuarrie for Star Trek: Planet of the Titans. Although the designations were not legible on screen in "Unification I", they appear on the study model, which first appeared in The Art of Star Trek (p. 56).
It is unclear what the registry or designation of this ship was intended to be. The nacelle pylons both prominently feature the number 4. Port nacelle features 4-CLN and the starboard nacelle features 444. On the top of the saucer section it reads B-24-CLN. The model was sold in the Propworx auction. The website of the auction features photos of the ship from various angles.
