Subnautica 2 Vehicles
Tadpole command module, Scout Ray and HAUL chassis — official databank text, Vehicle Bay recipes, and upgrade modules from game data.
The Tadpole is a single-seat command pod fabricated at a Vehicle Bay. Scout Ray and HAUL are dockable chassis built at a Utility Bay and swapped in the field.
Tadpole
Core moduleCommand module — docks with interchangeable chassis at a Utility Bay.
OPERATING INSTRUCTIONS Versatile single-pilot submarine. Provides unlimited oxygen while powered. Fabricate at a Vehicle Bay next to a moonpool—ensure that the moonpool is large and deep enough to accept the Tadpole. Recharge power cell when depleted. In the event of damage, apply standard repair tool.

Tadpole Haul Chassis
ChassisCargo chassis — extra hardpoint, storage pods, and passenger capacity.
OPERATING INSTRUCTIONS Dock Tadpole with HAUL rig. Store cargo in pods. Mount utility items to extra hardpoint. Passengers may ride on catamaran pods. Undock Tadpole to swap chassis.

Subnautica 2 Vehicles Overview
Subnautica 2 vehicles in Early Access center on the Tadpole mobility suite: a core submarine with interchangeable chassis for speed or cargo.
Each profile lists PDA operating instructions, fabrication ingredients, fragment scan unlocks where present, and linked modification items for crush depth and utility slots.
Data: 1 core, 2 chassis, 7 Tadpole upgrades.
How Vehicles Are Organized
Vehicle entries are split by practical role: the Tadpole core module, chassis options for speed or hauling, and the upgrade path that changes depth tolerance and mission utility.
Why Vehicle Data Matters For Progression
Vehicle progression controls route risk, travel time, and cargo throughput. Knowing what each chassis changes, what it costs to fabricate, and which modules unlock next helps you plan safer deep-biome runs.
Vehicle FAQ
What is the Tadpole in Subnautica 2?
The Tadpole is the core single-seat submarine. Scout Ray and HAUL are optional chassis you fabricate separately and dock in the field for speed or cargo.
Where do I build vehicles?
Fabricate the Tadpole at a Vehicle Bay beside a moonpool large enough for it. Build chassis at a Utility Bay, then undock and redock to swap.
How should I prioritize vehicle upgrades?
Prioritize upgrades that solve your next biome constraint first, usually depth tolerance and survivability. Speed or cargo-focused modules are strongest after your baseline range is stable.
Related Vehicle And Base Planning
Vehicle progression ties moonpool size, fragment scans, and material costs together — best planned before you commit titanium to a bay.
Use items for power cells and upgrade modules, buildings for Vehicle Bay and moonpool pieces, blueprints for fragment unlock chains, and the Crafting Planner to total fabrication before leaving your base.
