Because the two ships David made are able to be freely used:

IC: The ISAF Enterprise Warps into the area at Vent Delta( if it's still available). Ships are lowered down including the newest Submarines ISAF Vengeance and ISAF Suprise. They stay put until the Vengeance Class Submarines return with a map of the area. The Vengeance Class is chosen to scout the area because of its maneuverability and small profile above and below water. The Subs return and the fleet that had dropped down from the Enterprise moves to a Piller they found. They set up shop and the Enterprise turns around and warps away.
