Excelsior-class starshipEditThe main shuttlebay in Excelsior-class variants, such as the USS Enterprise-B, was located in the lower secondary hull. (TNG movie: Generations)
- The TNG reference: Star Trek: The Next Generation Sketchbook: The Movies has an MSD of the Enterprise-B showing the main shuttlebay located across the aft section of the primary hull where the port and starboard impulse engines are. This error does not appear on the actual MSD used in the film.
- Conversely, in the ST reference: USS Enterprise Owners' Workshop Manual, the shuttlebay is labelled as being at the aft of the secondary hull where the cargo bay is located. The actual main shuttlebay is labelled as the probe launch bay.
Galaxy-class starshipEditA Federation Galaxy-class starship's main shuttlebay was located on decks three and four of the saucer section with a lower shuttle maintenance floor on deck five.
The upper main shuttlebay was situated on deck three. It was surrounded by a viewing balcony, where crewmembers and other starship personnel could observe the goings-on below. In the central tower, there were two flight crew lounges, a shuttle systems programming office and the shuttlebay control room, which looked out over the entrance to the bay.The main shuttlebay deck was located on deck four. It was a cavernous eliptic toroidal area surrounding the central tower, with four banks of six shuttle fueling docks on the bay's inner bulkheads. The central tower housed two shuttle maintenance bays, the main computer core data trunks, turbolift shafts and the main stairwell. Separate from the tower, to port and starboard, were internal cargo elevators that ran from top to bottom of the primary hull. And on the port and starboard inner bulkheads was access to the deck's cargo bays and cargo transporters. Just inside the bay door were three shuttle lifts to the deck below.
The lower shuttle maintenance floor on deck five was directly below the shuttlebay entrance, serviced by the three shuttle lifts. (TNG reference: Star Trek: The Next Generation USS Enterprise NCC-1701-D Blueprints)In 2368, Commander William T. Riker ordered the venting of the USS Enterprise-D's main shuttlebay in order to propel the ship away from a collision course with the USS Bozeman. (TNG episode: "Cause and Effect")
