The Vanduul Warship Analysis notes that the Indefatigable has nearly the same tonnage of a abandoned vanduul carrier, called X12. The Galactic Guide for Cathcart originally said "The abandoned Indefatigable-class battleship you docked with to purchase narcotics a month ago may be an agro-habitat today" meaning several Indefatigable-class ships were built, though later versions of this guide removed the specific reference to the Indefatigable class.
