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.

This high-tech chamber allows biological organisms to enter a form of stasis via a rapid freezing process and be sustained in pods for a long duration. Cryo-chambers can be set to keep an organism in stasis for a set duration, indefinitely, or until certain conditions are met, such as arrival at a navigational milestone or if the vessel comes under attack. During the days before Drift travel, most starship crews used these chambers to survive the months-long trips between destinations. Some exploration ships still use cryo-chambers in lieu of crew quarters, particularly those that regularly travel in the Vast. The Azlanti Star Empire has developed its own variation on the cryo-chamber, which is more compact but virtually unknown outside of Azlanti space.
A cryo-chamber can hold up to eight Medium or smaller creatures or four Large creatures in stasis for as long as the systems have adequate power. A cryo-chamber can instead be outfitted to hold a single Huge or Gargantuan creature, and two cryo-chambers can be combined to hold a single Colossal creature.
While in stasis in a cryo-chamber, a creature no longer advances on affliction tracks, and doesn’t suffer from starvation, thirst, or sleep deprivation. Placing a creature in stasis or removing it from stasis takes 1 hour, after which the creature is sickened for 1 day unless it succeeds at a DC 25 Fortitude save
