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.

Mech Bay

Source Ports of Call pg. 28
PCU 15; Cost (in BP) 15
A mech bay takes up two expansion bays and can be installed only in a Large or larger ship. It can store 4 Huge mechs, 2 Gargantuan mechs, or 1 Colossal mech. While a mech is housed in a mech bay, repairs on it take half the time and shield regeneration is twice as fast. Mechs can be deployed from the bay directly to a planet’s surface if the ship is landed, or they can be loaded into an available drop pod (Starship Operations Manual 25) or sky crane (page 29).
