Starship Weapon

Whether the PCs are in the Vast or near a Pact Worlds planet, space is a dangerous place, plagued with hostile aliens, raiders, and worse. As a result, most ships protect themselves with a variety of weapons, ranging from laser cannons to solar torpedoes.
Weapons must be installed on special mounts on a ship, specified in the ship’s base frame. These mounts are designed for optimal firing and are placed so that they can be easily tied into the ship’s power and control systems. They also prevent the weapon from affecting the course or speed of a ship when fired.

Weapons are classified using the following key statistics.


This is the name of the weapon.


Weapons belong to one of three classifications. Light weapons can be mounted on any ship but are most typically found on smaller fighters and bombers. While dangerous, light weapons do not have the firepower necessary to damage very large starships. Heavy weapons are a serious threat to any vessel but can be mounted only on Medium or larger starships. Capital weapons can be mounted only on Huge or larger starships. Capital weapons can’t be brought to bear against Tiny or Small targets and are typically used only against other large vessels.


Starship weapons are one of two types. Direct-fire weapons fire projectiles or beams at amazing speed, targeting the opposing vessel’s AC. Tracking weapons’ projectiles are slower and must home in using a target’s TL. A tracking weapon’s projectile has a listed speed; once fired, it moves that number of hexes toward its target. Each subsequent round during the gunnery phase, it must succeed at a gunnery check against the target’s TL to continue to move its speed toward its target. On a failure, the projectile is lost. If the projectile reaches the target’s hex, it deals the listed damage.


Weapons have one of three ranges: short range (5 hexes), medium range (10 hexes), or long range (20 hexes). As with characterscale ranged attacks, an attack with a starship weapon takes a cumulative –2 penalty for each range increment (or fraction thereof, beyond the first) between it and the target. A gunner firing a tracking weapon takes a range penalty only on her first gunnery check, when the target is first acquired. A starship weapon can fire at a target up to 10 range increments away.


This is the distance in hexes a tracking weapon moves toward its target each round during the gunnery phase. Projectiles from a tracking weapon have perfect maneuverability, and as such, they have a minimum turn distance of 0 (see page 319).


This is the amount of damage (in Hull Points) the weapon deals when it successfully hits a target. See Shooting Starships on page 292 for guidelines on how starship weapons can affect characters.


This is the amount of PCU consumed by the weapon. It uses this amount continuously whenever the weapon is powered up and ready to fire.


This is the cost of the weapon in Build Points.

Special Properties

Some weapons have special properties, as noted above. These special properties and how they affect starship combat are described here. They can be found here.

Starship Operation Manual Expansion

The new starship weapons in this chapter use the rules presented starting on page 303 of the Starfinder Core Rulebook. The weapons appear in tables on pages 18–19, grouped first by weapon class (light, heavy, capital, or spinal-mount weapons) and then by type (direct-fire, ECM, melee, or tracking). The new ECM and melee starship weapon types appear on this page, and new starship weapon special properties appear on pages 12–17. In addition, sidebars accompanying these new weapon types and properties detail new starship crew actions involved with these technologies. For more on starship crew actions, see pages 322–326 of the Core Rulebook and pages 148–149 of the Starfinder Character Operations Manual.


In addition to direct-fire and tracking weapons, this section introduces two new starship weapon types: ECM modules and melee weapons.

Electronic Countermeasure Modules

Electronic countermeasure (ECM) modules are a type of powerful instrument designed to foil an enemy starship’s sensors, impair a starship’s systems, and in some cases alter the battlefield itself. ECM modules must be installed on weapon mounts, but they are activated by a science officer during the gunnery phase. ECM modules follow the same rules for range and quadrant targeting as conventional starship weapons.
When activating an ECM module, a science officer attempts a special gunnery check, adding their ranks in the Computers skill but adding neither their base attack bonus nor their ranks in the Piloting skill, and adding their Intelligence modifier in place of their Dexterity modifier; an NPC officer typically has a gunnery modifier equal to that of the gunner’s gunnery modifier. Compare the result of this gunnery check to the target’s Target Lock (TL). If the result equals or exceeds the target’s TL, the science officer hits and applies the ECM module’s effects. Due to the interference created by shields, starships with functioning shields in the targeted quadrant gain a +2 circumstance bonus to their TL against ECM modules. ECM modules do not deal critical damage.

Melee Weapons

A melee weapon uses some part of the starship to induce a direct collision between the attacking and defending starships, targeting the opposing vessel’s AC. Melee starship weapons always have a range of 1 hex, even if a special property would otherwise change the weapon’s range.


Any Supercolossal starship (page 36) can mount multiple capital weapons, but the dreaded ultranought can support even larger ordinance, known as spinal-mount weapons. These immense devices of destruction are built along the vessel’s entire length and are integrated into its core, channeling the power of the ship’s engines and reactors into massive, direct-fire attacks that obliterate most targets. A Supercolossal starship can mount at most one spinal-mount weapon, and a spinal-mount weapon must be mounted in the front quadrant.
A spinal-mount weapon must charge before firing. The starship’s engineer can begin charging the weapon as an engineer action during the engineering phase if they succeed at an Engineering check (DC = 10 + 1-1/2 × the starship’s tier) to activate the weapon. The weapon charges for the duration of that round and continues charging during the subsequent round.
On the third round, during the gunnery phase, the spinal- mount weapon can be fired with the shoot gunner action. Because aiming a spinal-mount weapon requires moving the starship, the gunner gains a +2 bonus to their gunnery check when using their ranks in Piloting, instead of their base attack bonus, to calculate their gunnery bonus for the weapon. If the gunner wants to use their base attack bonus, they gain a +1 bonus to their gunnery check if they are trained in Piloting. Additionally, if the gunner fires no other weapons during the round when they fire the spinal-mount weapon, it deals an additional 1 damage per damage die. Once a spinal-mount weapon is fired, it cannot be activated or recharged again for 2d4 rounds.
If the gunner doesn’t fire a spinal-mount weapon on the first round that it is fully charged, a member of the crew must take an engineer or gunner action each round (requiring no skill check) to keep it on standby. If no member of the crew takes this action, the weapon’s energy dissipates as if it had been fired, and it cannot be activated again for 2d4 rounds.


Starship weaponry can accommodate considerable modification, whether from corporate innovators or independent mechanics. A starship’s crew can incorporate one or more of the following upgrades to a weapon by multiplying the weapon’s BP cost by the listed value. Any restrictions on the types of weapons to which an upgrade can be applied are listed in the upgrade’s entry.
