Your ship in Starfield is more than a way to get between star systems. It is a customizable base of operations, a combat platform, and one of the deepest crafting systems Bethesda Game Studios has ever built into an RPG. The Ship Builder lets you assemble a vessel piece by piece from cockpits, habs, weapons, and engines, while ship-to-ship combat draws on a separate set of systems involving shields, power allocation, and targeting. This guide walks through both halves of that experience, from constructing your first custom ship to winning fights against pirates and Spacers in open space.
The essential modules every ship needs
Every ship in Starfield requires a specific set of core modules to function, and understanding them is the foundation of the Ship Builder. The Cockpit determines your crew size and is where piloting happens. The Grav Drive allows your ship to jump between star systems, while a Fuel Tank stores the Helium-3 that the Grav Drive consumes on each jump. Landing Gear must sit on the same ground level as your Landing Bay so the ship can touch down properly, and a Docker module, placed on the outer edge of the ship, lets you dock with other ships and space stations. Engines provide thrust and maneuverability, and their effectiveness depends heavily on your ship’s total mass.
The Reactor is arguably the most important piece, since its class determines the maximum class of every other module you can install, including weapons, shields, and grav drives. Upgrading to a higher-class reactor is often the single best way to unlock stronger parts across your entire build.
Managing mass and balancing your build
Every module you add increases your ship’s total mass, and mass works against your mobility. More engines can offset added weight, but stacking on additional engines increases mass again, creating a balancing act between firepower, defense, and how nimble your ship handles in a fight. A heavier ship also reduces your Grav Drive jump range, and if your ship becomes too heavy relative to your Grav Drive’s rating, you may not be able to jump at all. When designing a build, it helps to add modules deliberately and check your flight stats after each major addition rather than bulking up the entire ship before testing it.
Habs, cargo, and crew capacity
Habitat modules, or Habs, function as your crew’s living quarters and unlock interior features like workbenches, quarters, and research stations. Habs also affect how many crew members you can bring aboard, alongside the crew capacity set by your Cockpit. If you plan to run outposts and haul resources across systems, dedicating some cargo hold capacity is worthwhile, since cargo space determines how much loot and crafting material you can carry between stops.

Weapons and combat loadouts
You can equip a maximum of three weapon types on a ship, and each weapon must be assigned to a weapon group through the Flight Check menu before it will fire correctly in combat. A common and effective strategy is pairing laser weapons, which are highly effective at draining enemy shields, with ballistic weapons that excel at tearing through hull once those shields are down. Missiles offer a third option for high burst damage against tougher targets, though they usually require careful timing or a lock to land reliably.
Understanding power distribution in combat
Once a fight starts, managing your ship’s power allocation becomes the core skill of space combat. Your reactor generates a limited pool of power that gets distributed across systems including engines, shields, weapons, and grav drive, and you will rarely have enough to max out everything simultaneously. Routing more power into engines increases your speed and turning ability, more power into shields makes you tougher to bring down, and more power into weapons speeds up reload and recharge rates. Skilled pilots shift power on the fly depending on the situation, pouring power into engines to reposition or evade, then switching it to weapons for an alpha strike once they have a clean shot.
Shields, hull, and when to retreat
Your shield absorbs incoming damage and slowly regenerates on its own once you stop taking hits, so keeping it topped up with power is almost always worth prioritizing. Once your shield is depleted, incoming fire starts damaging your ship’s hull directly, which is far more dangerous since hull damage does not regenerate automatically the way shields do. If your hull drops into a critical range, it is often smarter to boost away, let your shield recharge, and re-engage rather than pushing through a fight your ship cannot currently win.
Targeting systems and boosting
Locking onto an enemy ship requires keeping them centered in your reticle until the game confirms a lock. If your character has invested in the Targeting Control Systems skill, a locked target lets you single out specific systems on the enemy ship, such as their engines or weapons, to disable key capabilities before finishing them off. Boosting, triggered with a dedicated input, is useful both offensively and defensively. It closes distance quickly when chasing a target and can also break missile locks or throw off enemy accuracy when you are the one being targeted.
Tips for building a well-rounded combat ship
New players often overload their first ship with weapons and forget shields and mobility, which leaves them vulnerable to being outmaneuvered even when they deal solid damage. A more reliable approach is to build around a mid-size reactor that supports decent shields and at least one weapon type you have skill points invested in, then expand from there as you acquire better parts through ship vendors, salvage, and quest rewards. Docking at ship services vendors in major settlements lets you preview parts before committing credits, which is worth doing regularly as you explore new systems and unlock access to higher-class components.
Ship building and ship combat in Starfield reward experimentation more than following a single fixed template. Whether you prefer a nimble fighter built around evasive boosting or a heavily shielded gunship that can absorb punishment while blowing through enemy hulls, the modular Ship Builder gives you the tools to build toward whichever combat style suits you best.
