Early Access availability
Ultra High Capacity Air Tank Availability
Older item lists can include equipment that has a name and a recipe but is unavailable in the current release. A larger tank name alone is not a reason to spend time on a fragment search.
Quick answer: The Ultra High Capacity Air Tank is marked unpublished in PC build 128456. Use the available Standard Air Tank and High Capacity Air Tank recipes for your next oxygen upgrade.

Route and unlock plan
Standard Air Tank and High Capacity Air Tank are the practical recipe pages to use.
Step 1
Use the available tank chain
Start with the Standard Air Tank, then prepare the Plasteel material for the High Capacity tank after blueprint access.
Step 2
Check route limits separately
More diver oxygen does not substitute for vehicle support, heat protection or a reliable exit.
Step 3
Follow equipment changes in patch notes
Early Access availability can change. Use the updates page before treating an older Ultra High Capacity list as a current crafting route.
