One level above the Main Deck is the Captain's Cabin. The main area of the suite served as his dining area and office. Just forward of it is his stateroom and bath as well as a small galley. The Captain used this cabin except when in a combat area which required his presence on the Bridge so much so that he had a secondary, sea cabin just aft of the Bridge. Beyond his personal use, the cabin was appropriate for small formal functions when the captain was required to host dignitaries. For larger functions, the Wardroom was chosen.

The Battleship was designed to be able to support an embarked flag officer and his staff. Two levels above the Main Deck is the Admiral's Cabin. Just as with the Captain's Cabin, the main area of the suite is the admiral's dining area and office and just forward is his stateroom and bath and a small galley.

While neither of these cabins can be entered, visitors can view the cabins through the portholes and windows.
