Here’s how to assign weapon groups in Starfield and clear those “Unassigned Weapon”/“Missing Weapon Assignment” errors while actually making your ship feel good in combat.

How to assign a weapon group (step‑by‑step)

Use this whenever you see that your ship “has weapons that must be assigned to a group” or some guns just won’t fire.

  1. Talk to a Ship Services Technician
    • You’ll find them at major spaceports or shipyards (New Atlantis, Neon, Akila, etc.).
  1. Open the Ship Builder / Modify Ship
    • Choose Modify Ship to enter the ship building screen.
  1. Open Flight Check
    • Look at the bottom‑right of the ship builder UI for Flight Check.
 * PC: press **C**.
 * Xbox controller: press the **Start/Menu** button.
  1. Go to the Weapons tab
    • In Flight Check, switch from Messages to the Weapons tab in the top‑right area.
  1. Assign weapons to groups
    • You’ll see your ship’s weapons and weapon group slots (like W0, W1, W2 or similar).
 * Highlight an unassigned weapon and assign it to one of the available groups.

 * Keep going until every installed weapon is in a valid group.
  1. Confirm status is clean
    • Go back to the Messages tab in Flight Check and check that the bottom‑right status is “Nominal” and that “Unassigned Weapon”/“Missing Weapon Assignment” warnings are gone.

Once you exit the menus, those groups are now mapped to your ship weapon keys/buttons, so tapping the weapon group controls will fire that specific group.

The weird rules: why you get errors

Starfield is picky about how weapons are grouped, and that’s where most people get confused in forum threads.

Key rules:

  • Only one weapon type per group
    • You can’t mix, for example, lasers and missiles in the same group.
* So: all lasers together, all missiles together, all ballistics together, etc., each in its own group.
  • No “duplicate type in multiple slots”
    • You can’t have two laser groups using different slots.
* All lasers must go into **one** group, not split across several.
  • Same‑model restriction for some setups
    • For lasers specifically, they must be the same model/brand if you want them assigned together in one group.
* Mixing different laser models in a single group isn’t allowed.
  • If a weapon doesn’t fit, the group will break
    • If you try to stick a weapon into a group where it doesn’t belong, the game may automatically unassign weapons in that group and throw errors again.

This is why players often feel like grouping is “buggy” in Reddit/Steam discussions—most of the time it’s just these hidden rules doing their thing.

Practical examples (to avoid headaches)

Think of these as little “recipes” for your ship loadouts.

  • Example 1: Classic three‑weapon ship
    • 1 laser, 1 ballistic, 1 missile.
    • Valid setup:
      • Group 1 (W0): all lasers.
      • Group 2 (W1): all ballistics.
      • Group 3 (W2): all missiles.
  • Example 2: Multiple lasers, one type
    • 3 identical laser turrets, 2 missile launchers.
    • Valid setup:
      • W0: all 3 identical lasers.
      • W1: both missiles.
    • If one laser is a different model, it may not join the group and can trigger an assignment conflict.
  • Example 3: “Why can’t I put laser + missile on one button?”
    • The game doesn’t allow a “combo group” like that.
* Design intent is: one group = one damage profile, so you swap groups depending on target rather than firing everything with one key.
