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.

Habitat Simulator

PCU 4; Cost (in BP) 6
This expansion bay can be configured to duplicate various environments, simulating them down to the smallest detail. The simulator is primarily used to clandestinely move creatures without their knowledge. For example, the grays have transplanted individuals threatened by natural disaster or environmental concerns without revealing their own existence. When used for this purpose, the simulator even slowly changes the appearance of stars in the sky until they match the night sky of the location to which the creatures in the simulator will be moved. The bay can also be used to covertly observe creatures in a simulation of their natural environment, benefiting from greater control over environmental effects such as weather. A habitat simulator can hold up to four Medium creatures (while still providing a believable simulation) and takes up 3 expansion bays. The simulator can sustain a particular environment for 1 month before it needs to be cleaned out, refreshed, and resupplied.
