Weapon

Every mount you fill is a promise that the void will answer with fire.

In Starfield's shipbuilding system, the Weapon slot is the primary offensive armament bay on any spacecraft. Every ship in the game—whether a small scout or a heavy freighter—features one or more dedicated weapon mounts where the player can equip, swap, and upgrade their chosen armaments. These mounts are the core of a ship's combat identity, determining whether it rakes enemies with sustained beam fire, lances them with high-impact kinetic shots, or saturates a target with missile volleys.

Weapons are not merely cosmetic add-ons; they directly feed into the ship's overall Weapon stat, which governs damage output, range, and fire rate during space combat. Because weapon bays are limited and each mount carries its own energy draw, choosing the right loadout is a central optimization puzzle for players who want their fleet to punch above its weight class.

Lore & Background

The shipyards of the Settled Systems treat weapon bays as the soul of a vessel. A hull without a cannon is, in the words of every dockhand from New Atlantis to the outer rings, just a very expensive lifeboat. Over the decades of the Constellation expansion, manufacturers developed distinct weapon philosophies: the rapid, low-damage Pulse Cannons favored by courier pilots who need to pepper targets while maneuvering; the long-range, high-impact Rail Guns preferred by military escorts; and the area-denial Missile Launchers that turn a single launch into a spreading storm of smart warheads.

Each weapon mount draws from the ship's total energy budget. A fully loaded heavy gunship may struggle to keep its shields at full charge between volleys, while a lightly armed interceptor can sprint at full engine output with weapons still hot. This trade-off is by design—the engineering teams behind the shipbuilding framework wanted players to feel the weight of every decision, to know that adding a third Rail Gun means accepting a slower turn rate or thinner shield regeneration.

In the broader lore, the proliferation of civilian-grade weapons on small freighters and scouts is a point of quiet tension. The Interplanetary Consortium's regulations technically limit armament class by vessel tonnage, but enforcement across the scattered outposts is… aspirational at best. Many of the weapons a player can find tucked into a derelict cargo bay or purchased from a back-alley vendor in Jemison were never meant to be on a ship that size. The fact that they work, and work beautifully, is a small rebellion written in plasma and tungsten.

Reader's Guide

Weapon slots are the offensive heart of your ship's stat block. Each hull has a fixed number of mounts (check the ship's spec sheet before purchasing—small scouts may have one, heavy gunships up to four). Every weapon you install contributes to your total Weapon stat and drains from your shared energy pool.

Weapon types and their roles:

Where to find weapons: browse the weapon racks at any shipyard (New Atlantis, Jemison, Akila, etc.), check vendor inventories at major outposts, or search the open world—derelict ships, abandoned facilities, and faction strongholds all cache weapons. Some rare mounts are tied to faction quests or high-level exploration.

Optimization tip: total energy drain from all mounted weapons plus engines plus shields must fit within your hull's energy budget. Overloading it will starve your shields or engines. A common DPS build is two Pulse Cannons + one Missile Launcher on a mid-size hull, leaving enough headroom for a solid shield rating. For a tank, go two Beams + one Pulse, accepting a lower top speed in exchange for sustained output.
