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.

Sample Acquisition Bay

This bay is equipped with a hybrid tractor beam that quickly pulls a target into the vessel. This beam can target a Large or smaller creature (or object of similar size) that is within 500 feet and visible to the starship’s sensors. However, the beam can’t be activated if the vessel is in starship combat. While within the beam, the target’s molecules are phased slightly, rendering the target incorporeal. The beam moves the target from its original position into the bay (or vice versa) over 2 rounds. If the target is conscious and unwilling, it can attempt a Fortitude saving throw (DC = 10 + 1-1/2 × the starship’s tier) when it is first struck with the beam to negate its effect.
