How to Automate Defense in Satisfactory

Updated 21 Oct 2026 Source Satisfactory in-game mechanics and community documentation, retrieved 21 October 2026 By

Automated defense means turrets, walls, and ammo lines that run without you. It protects outposts while you build elsewhere.

Why this matters

Hand-held weapons cannot cover an outpost overnight. Automated defense lets you expand safely into hostile areas.

Step-by-step

  1. Unlock turrets and walls in the HUB.
  2. Set up an ammo production line for the turrets.
  3. Place walls around the outpost footprint.
  4. Mount turrets at gaps and corners.
  5. Belt ammo to every turret.
  6. Connect the whole outpost to power.
  7. Test with a flyby before leaving.

Tips

  • Ammo lines matter as much as turrets
  • Power the outpost or turrets go dark
  • Corners and gaps first for turrets
  • Smokeless powder ammo beats basic

Practical notes

Ammo is the real constraint on turret lines, so build the ammo factory before the wall. Smokeless powder ammo outlasts basic rounds, which means fewer refills during long absences.

Belt ammo to every turret and give each one its own feed, because a shared line starves the far turrets first. Test the perimeter by flying past it once before you trust it with an unattended night.

A turret with no ammo belt is decoration, and decoration loses outposts.

Walls with gaps at the roofline let flyers straight into the machines you fenced.

Common mistakes

  • Turrets with no ammo line
  • Forgetting outpost power
  • Walls with gaps at the roofline
  • Leaving an outpost untested

Frequently asked questions

What ammo do turrets use?

Rifle ammo early, then better ammo tiers as you unlock them — belt whatever the turret accepts from a production line.
