Starship Expansion Bays

Most starships have room within their hull for one or more expansion bays, each of which can be converted to function in a wide variety of roles. Unfilled, these bays are simply storage space (and count as cargo holds), and for many large transport vessels, they remain this way. If a starship’s bays are instead used for guest quarters, the ship can serve as a transport vessel for soldiers, travelers, or refugees. If its bays are filled with medical bays and guest quarters, the ship becomes a mobile hospital.
The following options are available for most ships that have available expansion bays. If an option requires multiple bays, this is noted in its description; if it must consume PCU to function, the amount is listed in the table on page 300. An entire expansion bay must be used for a single purpose, even if it gives you multiple instances of that option. For example, if you select escape pods, that expansion bay gains all six escape pods—you can’t combine three escape pods and one life boat.
The PCU requirement and the Build Point costs of the expansion bay options can be found on page 300.

Supercolossal Note

A Supercolossal ship uses the same expansion bays as other starships do. A Supercolossal ship can hold an unlimited number of expansion bays, none of which ever go unused. Any expansion bay in a Supercolossal ship represents numerous chambers grouped together over a wide area or many decks and augmented with reserve systems and retaskable configurations. Therefore, a bay such as an arcane laboratory on a Supercolossal ship indicates not a single lab, but the ship’s facilities that allow the crew to perform tasks requiring an arcane lab. Enough of these spaces exist on a ship of the line to accommodate any number of crew members who might need access the ship’s specific expansion bays.
