Quick answer
Current Subnautica2.gg data lists Vehicle Fabricator as a Builder Tool construct using Titanium Ingot x2, Copper Ingot x1, and Glass x2. PC Gamer and AllThingsHow both point players toward a Moonpool-based setup: build enough base space, place the Moonpool, attach the Tadpole Dock, then use the Vehicle Fabricator for the Tadpole chain. Treat the recipe as patch-sensitive and check your PDA after updates. In practice, mark the vehicle bay with a Beacon and stock Glass before you craft the final Power Cell.
Field notes for vehicle crafting
Build the bay before the shopping list
Materials are not the hard part if the bay is cramped. Confirm Moonpool and dock space first, then haul ingots and Glass to a place that can actually use them.
Glass is the annoying quiet cost
Players remember ingots because they sound expensive. The run often stalls on Glass or Quartz because it felt too ordinary to stock ahead of time.
Treat the Fabricator as a route hub
Once it is placed, this corner of the base becomes the start of vehicle runs, repair checks, Power Cell swaps, and upgrade planning. Keep it readable.
Vehicle Fabricator route
Build for space before you build the station
PC Gamer warns that the Moonpool needs real room below the base because the Tadpole Dock goes downward. If the base is cramped or too close to terrain, the station plan gets annoying fast.
Prepare the ingot and glass materials
Subnautica2.gg currently lists Titanium Ingot x2, Copper Ingot x1, and Glass x2. That means you should solve Titanium, Copper, and Quartz routes before blaming the vehicle chain.
Mark the bay before the final craft
A Beacon beside the vehicle base keeps return trips painless while you move Glass, ingots, and Power Cell parts. Do this before the build session turns into three separate swims.
Place Moonpool and Tadpole Dock first
AllThingsHow describes the vehicle setup around Moonpool, Tadpole Dock, and Vehicle Fabricator pieces. Put the dock where the vehicle can enter cleanly instead of squeezing it into a storage corner.
Craft Power Cell only when the build chain is ready
The Power Cell is easy to make too early. Keep it tied to Tadpole progress, not a random spare part, especially while Strong Acid and Salt are still tight.
Leave room for upgrades
Once the Tadpole exists, depth and efficiency upgrades become the next search loop. A clean vehicle bay makes swapping routes and checking materials less painful.

Vehicle Fabricator checklist
| Need | What to confirm |
|---|---|
| Moonpool space | Enough clearance below and around the base. |
| Tadpole Dock | Placed where the vehicle path is not blocked by terrain. |
| Titanium Ingot x2 | Current Subnautica2.gg recipe data for Vehicle Fabricator. |
| Copper Ingot x1 | Current recipe data; recheck in the PDA after patches. |
| Glass x2 | Quartz route or stored Glass before the build push. |
| Beacon marker | Mark the vehicle bay before moving heavy materials. |
| Power Cell | Needed for Tadpole progress, not for random storage. |
Do not build the Moonpool into a tight corner
A pretty base layout can still be a bad vehicle bay. Give the Moonpool and dock more space than the preview seems to need, especially underneath. Rebuilding a bay after the materials are spent is the boring kind of expedition.
FAQ
How do you unlock Vehicle Fabricator in Subnautica 2?
Current public blueprint data points to a Builder Tool construct, while PC Gamer and AllThingsHow place it in the Moonpool and Tadpole Dock vehicle chain. Check the in-game PDA for the final unlock state after patches.
What is the Vehicle Fabricator recipe?
Subnautica2.gg currently lists Titanium Ingot x2, Copper Ingot x1, and Glass x2. Early Access recipes can move, so treat this as a checked snapshot rather than a permanent rule.
Why will the Vehicle Fabricator or Tadpole setup not fit?
The usual problem is base space. The Moonpool and Tadpole Dock need enough clearance, including room below the base, not just a clear wall panel.
Should I craft the Tadpole before building a proper bay?
No. Finish the Moonpool, dock, power chain, and repair plan first. The vehicle is much more useful when the base can actually support it.
