Medivac 12
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
Medivac 12 was a Medivac in the Caprican Expeditionary Fleet destroyed by the Sagittarian fleet during the Third Colonial Conflict.
Sometime after the reunification of the Fleet, the Galactica convoy discovered it drifting in space, under attack by the Cylons. It was populated with people who had died during the Cylon Holocaust, presumably clones.
