Chapter 9: Starships

Refitting and Upgrading Starships

Source Starfinder Core Rulebook pg. 305
As the PCs go on adventures and gain experience, they need an increasingly powerful starship to face tougher challenges. When the characters’ Average Party Level increases, so does the tier of their starship (see Table 9–1: Starship Base Statistics on page 294). The PCs receive a number of Build Points equal to the Build Points listed for their starship’s new tier – those listed for its previous tier, which they can use to upgrade their starship. For example, a group whose APL increases from 2 to 3 receives 20 BP that the PCs can use to upgrade their starship. This could represent salvage gathered during their exploits, an arrangement with a spacedock, or called-in favors from a wealthy patron. Some GMs might require PCs to visit a safe, inhabited world before they can spend these Build Points, but this shouldn’t be allowed to impact the campaign too much.

Also remember that at tier 4 and every 4 tiers thereafter, the starship gains an increase in Hull Points equal to the HP increment listed for its base frame.

Refitting Systems

Source Starfinder Core Rulebook pg. 305
If the PCs want to alter their starship before receiving additional Build Points (for instance, replacing a weapon with one that costs fewer Build Points or consumes less PCU), they can do so at a friendly spaceport (or safe landing zone) given enough time. If they replace a system or option with one that costs fewer Build Points, they can immediately spend the excess Build Points. Refitting a single system or starship weapon usually takes 1d4 days.

Upgrading Systems

Source Starfinder Core Rulebook pg. 305
PCs with Build Points to spare can replace a system or weapon with one that costs more Build Points by paying only the difference in cost between the two systems. If the cost is the same, the system can be upgraded for free, but the crew should keep the amount of PCU the starship’s power core produces in mind so they don’t exceed their power budget. When upgrading a weapon, remember that the starship’s frame starts with a certain number and type of weapon mounts (but see New Weapon Mounts below). Installing a single upgrade usually takes 1d4 days.

PCs can’t upgrade the base frame of their starship. They can rebuild their starship with a new base frame if they so desire (within the limits of their budget of Build Points, of course), but that new starship will have a different look (and should probably have a different name). PCs can purchase Huge and larger base frames only at the GM’s discretion, as these usually require large crews and thus are normally reserved for NPC starships.

Buying a whole new starship is a process that can take between 1d4 days and 1d4 months, depending on whether the PCs are purchasing a used starship from a spacedock or having a custom vessel built from scratch.

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).
