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 Reactor for Railjack's Avionics Capacity and Flux Energy Capacity for Tactical Abilities and Battle Avionics.

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 specializing certain attributes over others. Wreckage Components needs to be repaired either with resources or with a single use Rush Repair Drone. These have a build time of 12 hours upon contributing the resources needed. The Wreckage Components stats vary randomly.

Shield ArrayEdit

House Lavan Arrays generally have the best Shield Capacity, but House Zetki Arrays boast both the best Shield Regeneration Delay as well the best Shield Percent regenerated per second.

EnginesEdit

The default Boost is 2x, so an engine with 0.26 Boost Speed multiplier would have a Boost Speed of 2.26x. House Vidar has the best range in regards to bonus speed, while House Lavan grants the best Boost multipliers.

Base Railjack engine Speed is 307 m/s. Engines increase engine speed in km/h, where 1 km/h is equivalent to 5 m/s. Total speed can be calculated using the following formula;

Total Speed = [307 × (1 + Bonus % from Conic Nozzle)] + (Additional Engine Speed × 5)

NOTE: Because of the relationship between base speed and boosted speed, the best Vidar engines will always outperform the other engines both in base and boosted speed.

MK III Component ModifiersEdit

With the exception of the Sigma variants, all MK III Components have an additional special property in addition to the base stat increases.
