Constitution-class refit deck configuration
- Deck 1
- Bridge (Star Trek: The Motion Picture, et al.)
- Deck 3
- (C Deck) Science officers quarters (Star Trek III: The Search for Spock)
- Deck 4
- (D Deck) Admiral's quarters (Star Trek II: The Wrath of Khan, Kirk is shown leaving the turbolift on D Deck before talking to Dr. Marcus in his quarters.)
- Deck 5

A detailed partial cutaway sketch of the refit configuration
There is a discrepancy in The Making of Star Trek with the description of the primary hull as being eleven decks in height, but shown to be nine decks in height in a cutaway diagram. The secondary hull is stated to be sixteen decks in height, but shown in the diagram to be eight decks, with no exact locations given for the following features: fuel storage, supplies storage, main repair centers, water and waste reconversion, minimal quarters for engineers and star-drive personnel used only in the case of saucer separation and the hangar deck.
Captain Kirk's quarters door signage
A sign created for Star Trek VI: The Undiscovered Country showed Kirk's quarters on the USS Enterprise-A were on Deck 5, section 1, room 0179.
