The Component Factory in Last War: Survival produces Drone Component Chests that support long-term drone development. Upgrading the building reduces the time required to produce each chest, allowing you to collect components more frequently.
However, Component Factory upgrades become increasingly expensive and can occupy your construction queue for several days. This guide explains how the building works, when it unlocks, its upgrade requirements, and how to use its output efficiently.
How to Unlock the Component Factory
The Component Factory becomes available after your Headquarters reaches level 15. Once constructed, it automatically begins producing Level 1 Drone Component Chests.
The building does not produce a chest instantly. Instead, each chest requires a set production period. Higher Component Factory levels reduce this timer, allowing you to generate more chests over the same amount of time.
Because Headquarters progression controls when the building becomes available, players should prepare the required resources before reaching level 15. This allows the Component Factory to begin producing as soon as it is unlocked.
What Does the Component Factory Produce?
The Component Factory produces Level 1 Drone Component Chests. These chests contain components that can be used as part of the drone upgrade system.
Drone components improve different drone attributes and contribute to stronger combat performance. However, collecting components alone is not enough. You also need to understand which parts should be upgraded and how they fit into your wider drone development strategy.
For a more detailed explanation of individual component upgrades, read the Last War Drone Parts guide.
Component Factory Upgrade Requirements
Upgrading the Component Factory reduces the production time for each Drone Component Chest. The improvement at each individual level is relatively small, but the cumulative reduction becomes more valuable over long periods.
The table below lists the approximate upgrade resources, construction times, power increases, and component production times for levels 1 through 30.

Important considerations:
- Resource costs shown in the table are base estimates.
- Research, survivor effects, VIP status, construction buffs, and alliance assistance may change the actual upgrade time.
- Game updates may adjust costs or production values.
- Higher levels provide better long-term production, but each individual level only reduces the timer by a small amount.
Is the Component Factory Worth Upgrading?
The Component Factory is worth developing because it provides a continuous source of drone components. However, it should not automatically take priority over every Headquarters requirement or combat building.
The benefit comes from long-term production. For example, reducing the production timer by two minutes may appear minor at one level, but those reductions accumulate across repeated chest cycles.
Prioritize the Component Factory when:
- Your drone components are progressing too slowly.
- The building is far behind your Headquarters level.
- You collect the produced chests consistently.
- You have enough resources without delaying an essential upgrade.
- A construction or power event rewards building development.
- Your drone is becoming an important part of your main squad’s combat strength.
You may temporarily delay it when another building is required for Headquarters progression, troop development, research, or healing capacity.
How to Maximize Component Production
- Collect chests regularly: A completed chest may prevent the next production cycle from providing full value if it remains uncollected.
- Upgrade gradually: Keep the building progressing alongside the rest of your base instead of using all resources on it at once.
- Plan construction events: Long upgrades can provide more value when completed during events that reward building power.
- Request alliance help: Alliance assistance can reduce the remaining construction time.
- Use speed-ups selectively: Save construction speed-ups for long levels, event objectives, or situations where completing the building immediately provides a clear benefit.
- Maintain resource reserves: High-level upgrades require large amounts of Iron, Food, and Coins.
- Coordinate drone resources: Components are only one part of drone development, so balance them with Battle Data and other required materials.
Battle Data is another important resource used to improve your drone. The Last War Battle Data guide explains how to obtain it and how it supports drone upgrades.
Common Component Factory Mistakes
Leaving Completed Chests Uncollected
The Component Factory provides the most value when you collect its output regularly. Infrequent collection can reduce your total component gains over time.
Upgrading It Ahead of Essential Buildings
Drone progression is valuable, but it should not block a required Headquarters, Tech Center, troop, or hospital upgrade.
Expecting a Large Improvement From One Level
Each upgrade only reduces the chest timer slightly. The real benefit comes from combining many upgrades and maintaining continuous production.
Ignoring Other Drone Resources
A large number of components will not fully develop your drone if you lack Battle Data, drone parts, chips, or other required materials.
Using Components Without a Priority Plan
Not every drone upgrade provides equal value. Review your current combat needs before investing heavily in a specific component.
Once you begin developing the wider drone system, the Last War Drone Chip priority guide can help you decide which chip attributes deserve attention.
Frequently Asked Questions
At what Headquarters level does the Component Factory unlock?
The Component Factory becomes available at Headquarters level 15.
What does the Component Factory produce?
It automatically produces Level 1 Drone Component Chests.
What are drone components used for?
Drone components improve different drone attributes and contribute to stronger combat performance.
How often does the Component Factory produce a chest?
The timer depends on the building level. At level 1, the listed production time is four hours. At level 30, it is reduced to approximately three hours and two minutes.
Can I speed up component chest production?
The primary way to reduce the production timer is to upgrade the Component Factory. Temporary bonuses may also affect production depending on current game systems.
What resources are required for upgrades?
Component Factory upgrades require Iron and Food. Coins are also required from higher levels onward.
Can I obtain drone components elsewhere?
Drone components may also appear in events, reward chests, shops, or special offers. Availability can change between events and seasons.
Should I max the Component Factory immediately?
No. Upgrade it gradually while maintaining progress on your Headquarters, research, troop buildings, hospital, and resource economy.
Does alliance help reduce Component Factory upgrade time?
Yes. Alliance members can help reduce the remaining construction time after an upgrade begins.
Conclusion
The Component Factory provides a steady source of Drone Component Chests and becomes increasingly useful as drone development plays a larger role in your combat strength.
Upgrade the building gradually, collect its output regularly, and coordinate component production with Battle Data, drone parts, chips, and other required materials. This balanced approach will provide better results than focusing on a single drone resource.
Developing a competitive drone requires Headquarters progression, repeated Component Factory upgrades, regular chest collection, and investment across several drone systems.
