Starfield gives players a ton of options in terms of ships to acquire; however, if you intend to use the Ship Builder to modify that, the heart of your ship is its reactor. Reactors power all other ship systems (Weapons, Shield, Engines, and Grav. Drive).

Reactor Stats Explained

Reactors come with multiple important stats:

Reactor Class

Class: There are three classes of reactors in Starfield, A, B, and C. The reality is that Class C reactors outscore both B and A class reactors in most stat categories, but they weigh much more. However, they also unlock more ship modules you can install on your ship, as they also affect the class of your ship. Class A ships can only have Class A modules installed. Class B ships can have both Class A and B modules installed, while Class C ships can use modules of all three Classes. All three reactor classes require the Piloting Skill to use. You won’t be able to fly a ship if your Piloting skill does not match its class requirements:

  • Class A: Requires Piloting Rank 1
  • Class B: Requires Piloting Rank 3
  • Class C: Requires Piloting Rank 4

Power Generated

Power Generated is almost as important as a reactor’s Class. There is no point in installing better ship modules if you can’t use them at max power. The higher the power generated, the more components you can use at full power without constant adjustments to the ship systems. In terms of power generation, Class B reactors can get pretty close to Class C ones, so if you don’t need top-tier modules and aim for lower mass on your ship, they can be a viable option.


Reactors have a base health stat, which probably means that as they receive more damage, they start generating less power. If they lose all health, they don’t explode, but they get deactivated (or almost deactivated, generating very little power) like the rest of the ship modules. Consequently, a reactor with more health will withstand more damage until it temporarily breaks down, but it may take longer to get back to full power.

Repair Rate

I think repair rate is a stat available only for reactors. Since reactors are such a vital ship module, they can repair themselves so the ship is still operational, even if all other systems are disabled. Class C reactors tend to have higher repair rates but are more healthy. Evaluating how fast a reactor can recover depends on its health and repair rate, so a reactor with a higher repair rate may take as long as one with a lower repair rate if it has much more health.


The Hull value is the reactor’s contribution to the ship’s overall Hull (HP). The higher this number is, the more chance you have to survive a fight if your shield goes down.

Crew Capacity

Reactors can increase your ship’s crew capacity based on their Class:

  • Class A reactors increase Crew Capacity by 1.
  • Class B reactors increase Crew Capacity by 2.
  • Class C reactors increase Crew Capacity by 3.

Reactor Requirements

As already explained, the first reactor requirement is Piloting, and it’s related to the reactor’s class. The second requirement is Starship Design, as some reactors require a certain rank on this skill to use. The final requirement is your character’s level. You won’t have access to every reactor in the game right from the start. Instead, more powerful reactor models will be unlocked as you level up your character and progress through Starfield’s universe.

How Many Reactors Can My Ship Have?

Starfield ships can only have one reactor. This limitation can only be changed with mods.

Where to Buy Reactors in Starfield

If you are searching for a new reactor, look for it at Ship Services Technicians, Staryards, and Showrooms. Be aware that better reactors are unlocked as you level up.
