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.

Launch Tubes

Source Pact Worlds pg. 153
PCU 10; Cost (in BP) 5
Designed to fit on Medium and Large vessels, these tubes allow a ship to carry a single smaller vessel that can be launched at the start of any helm phase. A launch tube takes up two expansion bays and can hold one Tiny starship. If a vessel needs to dock in a launch tube during combat, it occurs at the end of the helm phase and requires a successful DC 10 Piloting skill check; this check takes a –1 penalty for each hex the smaller ship has moved this round. A failed check means that the ship doesn’t dock with the larger vessel.
