Expansion Bays

Source Starfinder Core Rulebook pg. 298
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.

Drift Booster

Source Starfinder #6: Empire of Bones pg. 46
PCU 40; Cost (in BP) 20
Note: The following Expansion Bay is compatible only with a Supercolossal ship.
A Drift booster is a rail for launching smaller ships into the Drift from within a Supercolossal vessel’s hangar bay. A smaller ship that launches from within the Supercolossal vessel’s hangar bay using the Drift booster can temporarily raise its Drift engine rating by 1. This increase lasts only as long as the smaller ship stays in the Drift and on the same course after launching using the Drift booster. If the boosted ship changes course or leaves the Drift, this temporary increase ends.
