Chapter 9: Starships / Refitting and Upgrading Starships

New Weapon Mounts

Source Starfinder Core Rulebook pg. 305
Greater dangers means the PCs will require more powerful weapons in order to survive and triumph. Unless they begin flying around with an escort of armed battlecruisers, the weapons they start with will eventually become inadequate. Bigger weapons require the correct weapon mounts, however.

By spending 4 BP, the crew can upgrade a light weapon mount in any of the aft, forward, port, or starboard arcs to a heavy weapon mount. By spending 6 BP, the crew can upgrade a light weapon mount on a turret to a heavy weapon mount. By spending 5 Build Points, the crew can upgrade a heavy weapon mount in any of the aft, forward, port, or starboard arcs to a capital weapon mount. Heavy weapons can be mounted on only Medium or larger starships. Capital weapons can be mounted on only Huge or larger starships and can’t be mounted on turrets.

By spending 3 BP, the crew can fit a new light weapon mount in any of the aft, forward, port, or starboard arcs with enough free space. By spending 5 BP, the crew can fit a new light weapon mount on a turret that has enough free space. Tiny and Small starships can have only two weapon mounts per arc (and per turret). Medium and Large starships can have only three weapon mounts per arc (and per turret). Huge and larger starships can have only four weapon mounts per arc (and per turret).
