The USS Bell (NCC-3224) was a Lynch-class starship decommisioned in 2281. It was renamed B-24-CLN and was assigned to Surplus Depot Z15.


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 episode: "Unification I")

This ship shares the same design with the mid 23rd century Federation Crossfield-class, with slight differentiation in the nacelles and pylons. (DIS episode: "Context Is for Kings", et al)


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.

During that year, the USS Enterprise-D flew past the ship during a visit at the Depot. (TNG episode: "Unification I")
