I surfaced at the Old Habitat with my HUD pinging and a knuckle-deep chill in my fingers. You can feel the timer of your lungs — no Fabricator, no vehicle, and the map still a puzzle. I found the Room blueprint tucked away on a shelf, like a pocket watch slipped between floorboards.
I’ve built my fair share of bases on Unknown Worlds’ worlds and I’ll walk you through the precise stops: where to go, which terminals to scan, and how to turn a Moonpool into a Tadpole launch bay. Read this as a short field manual — quick, practical, and written from the hatch.

If you want the Vehicle Fabricator, you first need the Room blueprint. Head to the Old Habitat, roughly 300m from your lifepod; it’s the weathered building with two rooms and sealed hatches. Go through the right-hand section and climb the ladder to the top floor.
Turn right from the ladder and you’ll hit a room with a NOA terminal. The Room blueprint sits on a shelf to the right of that terminal; while you’re there, scan the furniture schematics scattered nearby. You’ll also want the Processor blueprint unlocked to craft several advanced materials later.
How do I place the Vehicle Fabricator in Subnautica 2?
Back at your base, use the Habitat Builder to place the Room you just scanned. Make the room large enough to host a Moonpool — if the Moonpool can’t fit, enlarge the room. The Vehicle Fabricator is a Moonpool build option; open the Build Menu with your Habitat Builder tool and place it inside the Moonpool.
Tip from experience: place a few adjacent utility rooms so the Moonpool has breathing room. If the Moonpool’s footprint is too small, extend the connected rooms until the Vehicle Fabricator is placeable. Steam guides and community threads on the Subnautica 2 Steam hub often show compact Moonpool layouts if you want patterns to copy.
Quiet docking bays tell you where to build — How to craft the Tadpole submarine in Subnautica 2
Empty docks in real harbors often point to the obvious next step — here it’s the Tadpole Dock. Once the Vehicle Fabricator is in place, fit a Tadpole Dock to the Moonpool using the Habitat Builder.
Open the Vehicle Fabricator UI. The Tadpole will be listed as a craftable vehicle once the required fragments are collected and the Moonpool has a Tadpole Dock attached. Build the dock, then select the Tadpole and gather the materials the Fabricator lists—advanced parts will require the Processor for assembly.
Where do I find the Room blueprint?
The Room blueprint lives on the top floor shelf inside the Old Habitat’s right-hand building, beside the NOA terminal. It’s a short swim from the lifepod; check the ladder and the highest room first. If you’ve scanned furniture here, you’re already in the right place.
What materials are needed to craft the Tadpole?
The Fabricator lists the exact components when you select the Tadpole. You’ll commonly need base metals and some processed parts; if a recipe shows advanced items, build a Processor first. If you want community recipes and build tips, check the Subnautica 2 section on Steam and fan sites like Moyens I/O for screenshots and resource lists.
The Moonpool becomes your beacon when the Tadpole is ready — a single click in the Vehicle Fabricator launches construction. Place the dock, press craft, and watch the bay assemble your sub. After that, you can ride out further and stay underwater longer than your suit would allow, and your base becomes a true forward operating point.
Ready to trade your swim for a cockpit, or will you push one more trip to the Old Habitat before you seal the moonpool?
