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.

Quantum Defender

Source Starfinder #7: The Reach of Empire pg. 47
PCU 10; Cost (in BP) 5
A quantum defender allows a starship to enter an uncertain quantum state for a short time. During the helm phase, as an action, a science officer can activate the quantum defender by succeeding at a Computers check (DC = 10 + 1-1/2 × the starship’s tier). While the quantum defender is active, if an attack would normally hit the ship, the attacker must reroll the gunnery check and take the lower result. After that reroll, or at the end of a round during which no such reroll occurs, the ship returns to its normal state as the quantum defender deactivates.
