This is the area southwest of your naval base. It has a default of one repair dock and can be expanded to two. Its second and third map are the rough equivalent of 1-5 and 1-6 in the browser game, respectively. VB03 requires clearing the second map of this hex, and unlocks VB04, which allows you to unlock your fourth fleet.
