Railjacks are powerful battleships that allow Tenno to wage large-scale space combat across the Origin System, taking on fighters, Crewships, and dangerous Proxima missions in Warframe.
While a freshly constructed Railjack is strong enough for early encounters, its base stats are only the beginning of what the ship is truly capable of achieving.
Railjack Components allow you to improve shields, speed, and energy capacity even further, transforming your ship into a far more durable and efficient war machine for high-tier missions.
What Are Railjack Components?
Railjack Components are ship parts that determine your Railjack’s defensive strength, movement speed, and Battle Mod energy capacity during missions.
There are three main component types: Shield Array, Engines, and Reactor, each affecting a specific aspect of your ship’s performance.
Upgrading to higher-tier components increases their base stats and may provide additional passive bonuses at MK III.
Types of Railjack Components
1) Shield Arrays
Shield Arrays determine your Railjack’s maximum shield capacity and affect how quickly shields begin regenerating after taking damage during missions.
Higher-tier Shield Arrays greatly improve survivability in tougher Proxima regions, and MK III versions also include a house-specific passive bonus that can further enhance defensive performance.
2) Engines
Engines increase your Railjack’s base movement speed and improve boost multiplier, allowing faster objective completion and better repositioning in combat.
MK I Engines improve base speed, while MK II and MK III provide stronger boost scaling, with MK III versions also including a house-based passive bonus for additional utility.
3) Reactors
Reactors increase Plexus Mod Capacity, which determines how many Railjack mods you can equip for your ship’s overall configuration.
MK III Reactors provide the highest scaling and improve Plexus/Battle Mod effectiveness, making them essential for endgame builds.
4) Plating
Plating increases your Railjack’s hull durability and overall armor, reducing damage taken from enemy attacks.
Higher-tier Plating provides the most durability, and MK III versions can include a house-specific passive bonus for extra resilience in difficult missions.
How To Get Railjack Components?
Railjack Components drop during Proxima missions as wreckage from enemy fighters, Crewships, and elite units that you defeat throughout the mission.
Wreckage appears as purple loot in space and must be collected before extraction, otherwise it will not be added to your inventory.
You may also receive additional components as end-of-mission rewards depending on the Proxima region and the mission type you complete.
- Collect wreckage from enemies during Proxima missions.
- Pick it up before extraction or you lose it.
- End-of-mission rewards can give components.
- Sigma components come from Clan research.
Where To Get Railjack Components?
Higher Proxima regions drop stronger Railjack components, with late-game areas like Pluto and Veil giving the best MK III wreckage.
Components appear as purple wreckage from enemies during missions and must be collected before extraction, while Sigma components are obtained through Clan research.
Railjack components can be collected across all Proxima regions, with tier and availability depending on the mission location and difficulty.
Railjack Component Locations and Tiers
- MK I – Earth / Venus Proxima
- MK II – Saturn / Neptune Proxima
- MK III – Pluto / Veil Proxima
Railjack Components Farming
If you want to farm Railjack components, the most efficient method is to run consistent, quick missions in the Proxima region that matches the tier you are targeting.
Veil and Pluto Proxima missions are the most common places to farm high‑tier (MK III) wreckage due to their enemy level and reward tables offering better drops.
Farming missions with good enemy density and fewer objectives will maximize the number of wreckage drops you can collect per run, improving your overall component yield.
Railjack Building Components
Obtained wreckage from Railjack missions appears in your inventory and must be inspected and repaired before it can be used.
Go to the Railjack Configure console in your Dry Dock, select the part you want to repair, and begin repairs which take time and resources but can be completed instantly with a Rush Repair Drone.
There is a limit of 30 inspected wreckage slots, and once you reach this cap you must scrap or repair before inspecting more parts.
Railjack Components Requirements
Lavan, Vidar, and Zetki components can be used once they have been built and repaired, and they provide full functionality immediately for your Railjack once installed.
Sigma components must be researched in the Clan Dojo before acquisition, but they are ready to use immediately after research.
Equipping Railjack Components
Once you have repaired a Railjack component, you can equip it from the Configure screen in the Dry Dock or Orbiter by selecting it and confirming installation.
You can change components at any time if you have available slots, allowing you to swap parts to optimize your Railjack for specific missions or objectives.
Railjack Component Houses
Railjack components belong to four houses: Sigma, Lavan, Vidar, and Zetki, each with different stat tendencies that affect shields, speed, Plexus capacity, or hull durability.
Higher-tier components, especially MK III, often include a passive bonus unique to their house, which can further enhance performance during missions.
Railjack Components Trade
Railjack components, including both wreckage and repaired parts, cannot be traded between players, so you must farm or research all parts yourself to fully equip your ship.
Because stat rolls vary even among components of the same house and tier, collecting multiple wreckage drops allows you to select the best rolls or use Valence Fusion to strengthen your Railjack further.

Reactor Unique Traits
Mk III Reactor wreckages can roll a unique House-specific bonus when repaired, giving each component an extra effect beyond its base stats.
Lavan
- Equipping Lavan Hull Plating increases max Shields by 25%.
- Tenno gain 50% Damage increase for 5 seconds after being launched from the Slingshot.
Vidar
- +100% damage immunity duration after a Major Breach is repaired.
- Tenno gain 50% Speed Boost for 5 seconds when deploying their Archwing.
Zetki
- 50% chance that an Electric Hazard will repair automatically after 5 seconds.
- 50% chance that a Fire Hazard will repair automatically after 5 seconds.
- 50% chance that an Ice Hazard will repair automatically after 5 seconds.
Valence Fusion
Valence Fusion is a feature added in the Railjack updates that allows you to combine two components into one, increasing the resulting part’s stats and overall effectiveness.
To do this, select the component you want to upgrade and choose another component you own, whether it has been repaired or not.
During the fusion process, you may have the option to select which stat will carry over to the new component, letting you control the outcome.
Once confirmed, the second component is consumed, and the new fused part appears in your inventory with its updated stats and bonuses.
Verdict
Railjack component stats can vary slightly between drops, so it’s important to collect multiple wreckages to ensure you can pick the best rolls for your build.
Some components may not have certain House-specific bonuses, so gathering as many drops as possible before deciding which to use or fuse will maximize your ship’s potential.
Using Valence Fusion with components and Avionics lets you optimize stats and bonuses, making it easier to create a Railjack tailored for your missions.
