Aerospace Materials may not be as crucial for character progression in Arknights Endfield, but they're just as important. These are used to expand and upgrade the Dijiang, Endfield Industries' home base in space, and without it, players are going to miss out on a lot of passive resource production. For better or worse, getting Aerospace Materials itself is a passive affair — you won't have to work much to get them, but it'll take a fair bit of time before you can start stockpiling them. Here's a quick guide showing you where to get Aerospace Materials in Arknights Endfield.

Unlike most other types of materials in Endfield, Aerospace Materials aren't typically picked up from loot sources. Instead, they're claimed via Recycling Stations. These are scattered all across the game's regions, and you can easily find them by looking for an owl symbol on your map.

Activating a Recycling Station is free, and once you do so, you'll get a small amount of Aerospace Materials for your trouble. That's not all, though. Recycling Stations passively replenish their stocks of Aerospace Materials over time. It'll take 24 hours before you can claim more materials.

Upgrading Recycling Stations

Normally, you'd only get 3 Aerospace Materials from a Recycling Station. However, if you upgrade them, not only will you get more materials per batch, but you'll also get higher-rarity Aerospace Materials.

To upgrade Recycling Stations, you'll need a lot of Stock Bills, which is one of the types of currency in Endfield. Unlike the T-Creds that you spend to upgrade your Operators, Stock Bills are for material purchases within the various regions of Talos-II. T he best and most consistent way to get regional Stock Bills is to sell products to the people living near your Outposts.

Outposts will buy the materials and resources you produce in your AIC factories, and different items sell for different prices. If you want to get as many Stock Bills as possible via Outpost trading, pay attention to what the people of that Outpost need most. Go to the Outpost Management screen and check the prices of the items you can sell.

Aerospace Materials are used to upgrade the Dijian Control Nexus and create additional Cabins for passive resource production. As you level up the Dijiang, you'll be able to make more rare materials like Red Boletes, Kalkonyx, and more even while you're not playing the game.
