Railjack/Components

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 components Blueprints can be researched in the Dry Dock research console, then built 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 bought from the market for. These have a build time of 12 hours upon contributing the resources needed. The Wreckage Components stats vary randomly.

Shield Array
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.

Engines
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

Reactor
House Vidar Reactors can provide the highest increase to Avionics Capacity, while House Zetki reactors can provide the best increase to Flux Capacity.

MK III Component Modifiers
MK III Components (with the exception of the Sigma variants) have a random special property in addition to the base stat increases.

Manufacturing Requirements
Manufacturing/Repair costs are the same for Shield Arrays, Engines and Reactors of the same House and generation
