Pocket Base v21

 TL;DR

A modular, EARN 21-compatible base capable of producing nearly all Vanilla and Space Age items, launching numerous rockets, and achieving up to 405 SPM in science production.

The Story

My Quick Start Base (QSB) is designed for the early stages of the game. It’s meant to be modular, compact, and easily defensible. While it serves its initial purpose well, its small footprint becomes a limitation as you move toward a mega base or need to transport items between planets. Due to its size, the QSB doesn’t produce certain critical items—like blue belts, beacons, or T2 & T3 modules—needed for my Rail Blocks or larger setups. It also has very limited yellow and purple science production.

The Pocket Base is the next evolutionary step after the QSB.

Same Idea, New Approach

Like previous versions, Pocket Base v21 aims to produce everything you need in a well-organized area. Stage-1 can be constructed by EARN Construction Service Trains that deliver items from the QSB, and then it can produce the rest of the required items on its own.

The key difference in v21 is that it’s designed specifically for Factorio 2.0 and the Space Age DLC. This ensures you can fully utilize new science packs and other Factorio 2.0 benefits. It also uses the latest EARN 21 Framework, featuring numerous improvements over older versions.

How to Build the Pocket Base

• Stage-1: Manually place the Construction Service Station on Stage-1. Ensure it’s connected to the rail network so the Service Train can begin delivering materials.

• Stage-2: After Stage-1 is complete, place Stage-2 and let it finish building.

• Full Base Tier-1: Once Stage-2 is done, place the Full Base Tier-1 to start producing science packs.

Later, you can upgrade belts and modules with Tier-2 and Tier-3 blueprints.
You’ll need to use super-force build mode to upgrade existing entities (belts, chests, assemblers).

Capabilities

• Integrated Service Station: Allows self-expansion with support from the QSB.

• Electric Furnace Smelting with Modules

• Oil Processing

• Green, Red, and Blue Circuit Production

• Uranium Processing

• Ammo Hub

• Comprehensive Mall producing almost everything you need

• Science setup capable of up to 410 SPM

• Module production for self-upgrades and future expansions

• Built-in Service Hub

Compatibility

Pocket Base v21 uses EARN v21 tracks, stations, and trains. If you’re using an older version of EARN, you may need to consider previous Pocket Base versions.

There are two Pocket Base editions:

• Vanilla Edition: For Factorio 2.0 without the Space Age DLC.

• Space Age Edition: Requires the Space Age DLC.

Note:

The Pocket Base was designed and is maintained primarily by MisterGrimmJaw on our Discord Server. I assisted with some design changes, but most of the credit goes to him.
