The Railjack has three main components that determine its stats: Shield Arrays for Shield capacity and regeneration rate/delay; Engines for top speed, acceleration, and turning rate; and Reactors for Railjack's Avionics Capacity and Flux Energy Capacity for Battle Avionics and Ability Kinesis.

Sigma versions of armaments can be researched and purchased in the Dry Dock research console, then installed in the Railjack console. These have no build time once all the resources needed to build them are contributed.

House versions can be found as Wreckage in missions, with each House favoring certain attributes over others. Wreckage Components need to be repaired either with resources taking 12 hours to complete (this can be rushed for Platinum6420), or instantly without using any resources by expending a single-use Rush Repair Drone. The Wreckage Components stats vary randomly.

With the exception of the Sigma variants, all MK III Components have an additional special unique trait in addition to the base stat increases, and each component from each house comes with 2 different variants of the trait (except Vidar Shield Array that has an extra variant for a total of 3 different unique traits).

Two Component and Armament slots can be purchased when your storage is full (base capacity is 8 built components and armaments) for Platinum6412.

Shield ArrayEdit

Base shield amount is 1,000, base shield recharge is 5% per second, and base shield recharge delay is 5 seconds. House Lavan Arrays have the biggest potential Shield Capacity but the worst potential shield recharge, House Zetki Arrays are the reverse with the smallest potential Shield Capacity and the best potential shield recharge, while House Vidar offers the best balance between the two. Uniquely among MK III components, Vidar Shield Array can come with one of 3 different variants of the unique trait (all others can come in one of only 2).

EnginesEdit

Base Railjack Engine speed is 150 m/s, and the bonus from Engines is additive. Total speed can be calculated using the following formula:

Total Base Speed = [150 × (1 + Bonus % from HouseZetki Conic Nozzle)] + (Additional Engine Speed)

Base Boost Multiplier is 1.25x, and the bonus from Engines is additive, but at least in the UI, the Boost Multiplier is rounded to the nearest .1. For example, an Engine with +0.17 Boost Speed Multiplier would show an Engine Boost value of 1.4x.

Total Boost Multiplier = [1.25 × (1 + Bonus % from HouseZetki Ion Burn)] + (Additional Boost Multiplier)

House Vidar has the highest possible base Engine Speed, while for MK II and MK III versions House Lavan grants both the best possible Boost Speed Multiplier and the best possible maximum Speed while boosting. House Zetki tries to offer a balance between the two, however this translates into the slowest potential Speed while boosting for MK III version.

ReactorEdit

The base capacity for Avionics is 30 and base capacity for Flux Energy is 350. Flux Energy is needed to activate Battle Avionics and Ability Kinesis. It can be produced in Railjack Payload & Resource Forge.

House Vidar Reactors can provide the highest increase to Avionics Capacity, House Zetki reactors can provide the best increase to Flux Capacity, and House Lavan can provide the best balance between the two.

Valence FusionEdit

As of Update 27.4, repaired components can be upgraded by using "Valence Fusion" that allows fusing into them either a duplicate repaired component, or a non-repaired piece of wreckage. In both cases the fused part must be of the same type and house (MK may be different however, as well as the MK III unique trait). Repaired components will require some Dirac for Valence Fusion, while non-repaired wreckage require 40% of its repair cost (including Credits). Valence Fusion is completed instantly.

  • Combining parts of matching tiers will give +10% improvement in each stat up to the maximum possible from the part with the best stat (and will allow the player to choose the unique trait from either part - if they are different).
    • E.g. fusing together two MK III Vidar Reactor parts:
      • one repaired component with 99 avionics capacity, 18 flux capacity and "+100% damage immunity duration after a Major Breach is repaired" unique trait.
      • another non-repaired wreckage with 91 avionics capacity, 97 flux capacity and "Tenno gain 50% Speed Boost for 5s when deploying their Archwing" unique trait.
    • will produce a repaired MK III Vidar Reactor with 100 avionics capacity, 100 flux capacity and the unique trait will be chosen by the player from that of either of the 2 parts.
  • Combining one tier removed parts will give +5% improvement in each stat up to the maximum possible from the part with the best stat for each stat present in both parts.
    • E.g. fusing together a repaired MK III Lavan Shield Array and a non-repaired MK II Lavan Shield Array wreckage - this cannot improve shield regeneration per second, as this stat is not present in the MK II part.
  • Combining two tier removed parts will give +2% improvement in each stat up to the maximum possible from the part with the best stat for each stat present in both parts.
    • E.g. fusing together a repaired MK III Zetki Engine and a non-repaired MK I Zetki Engine - this can improve maximum speed, but cannot improve boost multiplier, as this stat is not present in the MK I part.
  • Note that House Sigma components cannot be fused together.

To perform Valence Fusion, players must click on the component desired to be upgraded, and then the part to be used as the donor. If the component has a different MK III unique trait, the player is prompted to select one. If the player does not have enough resources, a failure message will notify the player which resources they are missing. Once the components have been selected and the player has enough resources, a confirmation screen displays the desired component's new bonus values and warns that the transfer will consume the selected donor component along with the required resources. Players are then prompted to type FUSE to confirm the fusion, after which the fusion completes instantly.
