How To Build Your Ship - Ship Parts Upgrade

Last Updated:

The Ship Building Guide for Starfield. Includes how to use Ship Builder, add Weapons, Cargo, and changes of Ship Modules Class.

Table of Contents

Two Types of Ship Building

1. "Upgrade Ship" For Boosting Stats

This mode enhances the performance of installed ship parts, allowing you to Upgrade and Change the individual parts without worrying about position adjustments or other details.

2. "Ship Builder" For Full Customization

Unlike "Upgrade Ship," this mode allows you to add or delete parts. Customizing your ship is highly flexible, but there are also restrictions on modification.

Modify Ship Parts With "Upgrade Ship"

Priority To Upgrade Ship Parts


ReactorIncreases the power available to other ship components. Note that to pilot a ship with an upgraded reactor, you must also have a high Piloting skill rank.
WeaponsEnhances the combat performance of your ship.
CargoIncreases storage capacity.
EnginesBoosts the speed of your ship.

Start With Parts That Are Limited To One

MuduleHow To Choose
ReactorHigher power allows all components to be supplied.
Grav DriveHigher Grav Jump Thrust allows you to Fast Travel further.
ShieldHigher Health offer more protection.
CockpitHigher Hull provides higher durability for your ship.
DockerFor docking with other ships. No functional stats. Choose what you like.
Landing BayFor landing on planets. No functional stats. Choose what you like.

Starting with a set of non-negotiable components, each limited to one per ship, is essential when building a ship. This makes it easier to allocate the remaining components.

Use a Reactor of the Highest Possible Class

Since you cannot attach Modules of a higher class than the Reactor, you should start with the Reactor of the highest class available.

Modules (Other than Reactors) with a Class

Grav DriveHigher class increases the Jump Range but requires more Skills.
ShieldsHigher class reduces more incoming damage.
EnginesLimited to four.
Higher class doesn't result in higher Speed but more Health or less Required Power.
WeaponsLimited to three.
Higher-classed EM and PAR weapons offer better performance.

Add Functional Modules

MuduleHow To Choose
Fuel TanksHigher Fuel allows you to jump further.
CargoHigher Capacity provides more inventory space.
Shielded Cargo can be used to hide Contraband.
HabsRelated to Crew Slots and Interior Types. Choose what you need.
Landing GearsAt least two per ship.
Higher Lander Thrust supports more ship mass.

*There is no upper limit to the modules above.

Choose Modules With Higher Stats But Lower Mass

Mass refers to the weight of your ship, including all components. If Mass exceeds Thrust, Mobility will decrease, limiting speed and maneuverability. So, build a strong ship while keeping Mass in check.

See The Flight Check For Errors

See the errors from the Flight Check

It is crucial to learn the rules of shipbuilding. Any errors will be flagged in Flight Check with an explanation—press C to see how to fix the errors.

How To Fix Errors While Ship Building

Common Errors While Shipbuilding

Unattached ModulesShip has unattached modules.
→ Attach the modules properly on your ship.
Ship CostShip cost exceeds available credits.
