NCC-502
NCC-502 was the registry number for a Federation  freighter that was in service with Starfleet during the mid-23rd century. This ship was fully automated and carried no crew. Sometime prior to 2280 it suffered a catastrophic failure after suffering damage to its hull, resulting in the spillage of cargo, said to be "crates [..] brimming with unique Starfleet technology."  

In 2380, these ship's cargo was the subject of a dispute between the  and a Drookmani ship that had attempted to salvage the cargo. When the dispute went hot, the Drookmani, using a tractor beam, propelled the wreck of these ship into the Cerritos. ()
