Drone racks G and GX aren't fully or completely implemented in SFC. They are supposed to have an ADD (Anti-Drone Defense) loadout. The rack's mode of operation is supposed to be switchable between forms each SFB 'turn'.

To compensate, I've decided to add an ADD launcher (1 reload only) for each drone rack. This launcher increases the BPV by 1:

• 1/2 BPV for the extra hit
• 1/2 BPV for the bonus of being able to use the ADD at the same time.

Conversion Rules

Drone rack G

• Keep the Drone racks G as-is.
• add an ADD6, 1 reload, to the ship. 1 ADD per DroG.
• increase the BPV by 1 per added ADD6.

Drone rack GX

• set up a Drone rack B instead of G. The GX racks has a similar loadout to the B.
• set up a separate ADD12 with 1 reload.
• increase the BPV by 1 per added ADD12.
