SS Robert Fox

The SS Robert Fox was a small warp vessel which, in 2293, was caught and destroyed by an energy phenomenon known as the Nexus while transporting El-Aurian refugees through Federation space. The USS Enterprise (NCC-1701-B), responding to their distress call, was able to rescue 47 of the 150 crew and passengers aboard. 

Among the El-Aurians rescued from the Robert Fox were Guinan, Tolian Soran, and Yuriel Tyvan.
