They have presumably stayed there for the duration of the Dominion occupation of the station. X - The Rio Grande crashed on an unnamed planet, but was salvaged by the Defiant. The first Runabout was most likely the U.S.S. Danube , after which the small ships' class was named. The midsection contains a detachable module which may be changed for different mission profiles, though with three Runabouts available, this will not likely be used very often. The aft section of the Runabout holds living accomodations for up to 40 people, though the area would be very crowded with that number.
