Ultra High Capacity Air Tank Guide
Ultra High Capacity Air Tank searches usually happen when a player can reach a route but cannot work there long enough. The page should help decide whether more oxygen is the right fix or whether vehicle and route upgrades matter more.
Quick answer: Ultra High Capacity Air Tank is a later oxygen-margin upgrade for longer wreck, resource, and Alien Ruins route attempts. This page covers the common Ultra High Capacity name and the Large Air Tank wording until the live Fabricator label is settled. Exact stats, prerequisite, and costs need an in-game check.

Route and unlock plan
Mid-depth oxygen planning, Alien Ruins preparation, and wreck route margin.
Step 1
Use High Capacity Air Tank first
Ultra High Capacity Air Tank is best treated as the next oxygen step after the middle upgrade is understood.
Step 2
Craft it for work time
It helps when you can reach a location but need more time to scan, gather, or find the exit.
Step 3
Do not ignore vehicles
For some routes, Tadpole depth and support beat more diver oxygen.
Step 4
Check exact stats
Oxygen value, recipe, and prerequisite need in-game confirmation.
Player decisions
| Question | Status | Rule |
|---|---|---|
| Best timing | Mid-route pressure | Get it when repeated trips are failing because the working window is too short. |
| Main value | Longer dives | It increases route margin, especially in wrecks and deep material checks. |
| Competing solution | Vehicle support | Sometimes Tadpole upgrades solve the route better than another tank. |
| What to hold | Exact numbers | Do not publish oxygen values until checked in-game. |

Questions people ask
Is Ultra High Capacity Air Tank the same as Large Air Tank?
This page uses the player-facing Ultra High Capacity Air Tank search name while tracking Large Air Tank as a naming variant. Confirm the live in-game label before publishing fixed recipe or stat rows.
Is Ultra High Capacity Air Tank worth it?
Yes when the route is known but the oxygen window is too short for scans, gathering, or safe exits.
Should I get Ultra High Capacity Air Tank before Tadpole upgrades?
It depends on the blocker. More diver oxygen helps some routes; vehicle support is better for others.
Can we publish Ultra High Capacity Air Tank stats?
Only after checking the recipe and oxygen value in the current build.
