Deck-by-Deck Chart

(Please note that Charleston-class vessels carry an upper sensor pylon akin to that seen on the Nebula-class vessel. This pylon comprises 6 additional decks, denoted "Pylon 1" through "Pylon 6" -- but they contain little more than maintenance passageways and interfaces for changing the sensor package.)
