What to know
- The Scout Ray Chassis is a modular Tadpole upgrade focused on speed and maneuverability.
- You can find its blueprint inside the Tadpole Pens area during the main progression path.
- The chassis is crafted using the Vehicle Fabricator after scanning the fragment.
- It improves acceleration, turning, and top speed, but sacrifices extra storage capacity.
If you have already unlocked the Tadpole vehicle in Subnautica 2, the Scout Ray Chassis is one of the best upgrades you can build early-to-mid game. It dramatically changes how the vehicle handles underwater, making exploration smoother and helping you escape aggressive creatures more easily.
The chassis system is one of the biggest new vehicle mechanics added to Subnautica 2, allowing you to customize the Tadpole depending on whether you prefer fast exploration or resource hauling. The Scout Ray variant is designed specifically for mobility and scouting dangerous areas quickly.

Where to find the Scout Ray Chassis blueprint
The Scout Ray Chassis blueprint is located inside the Tadpole Pens area which is about 600 meters from the lifepd in southeast direction. This region becomes accessible as you progress through the main story and begin exploring deeper underwater facilities connected to the Tadpole questline.
This location also acts as a progression hub for several important vehicle unlocks in the game. You should already have the basic Tadpole vehicle before heading here, since the area contains deeper routes and hostile threats that are difficult to navigate without a vehicle.
How to unlock the Scout Ray Chassis
To unlock the blueprint, you need to scan the correct fragment using your Scanner tool.
How the unlock process works
| Requirement | Needed? |
|---|---|
| Scanner Tool | Yes |
| Tadpole Vehicle | Recommended |
| Vehicle Fabricator | Required later |
| Fragment Scan | Required |
| Story Progression | Partial |
How to scan the fragment
Step 1
Travel to the Tadpole Pens area and explore the interior sections carefully. The blueprint fragment is usually positioned near Tadpole equipment or docking structures.
Step 2
Equip your Scanner and look for the Tadpole Scout Ray Fragment.
Step 3
Scan the fragment completely until the blueprint unlock notification appears on-screen.
Step 4
Return to your base and access the Vehicle Fabricator connected to your Tadpole Dock setup.
Once scanned, the blueprint becomes permanently available for crafting.
Crafting recipe for the Scout Ray Chassis
After unlocking the blueprint, you can craft it using the following materials.
| Material | Quantity |
|---|---|
| Plasteel Ingot | 2 |
| Advanced Wiring Kit | 1 |
| Dedicated Core | 1 |
| Strong Acid | 1 |
Some of these materials are mid-game resources, especially the Dedicated Core and Strong Acid, so you may need additional biome exploration before crafting the upgrade.
How to equip and use the Scout Ray Chassis
The Scout Ray is not a separate vehicle. Instead, it functions as a chassis attachment for the Tadpole.
The Tadpole in Subnautica 2 supports modular chassis swapping. You dock the Tadpole into the chassis platform and swap configurations depending on your needs. Here is how to install the Scout Ray Chassis in Subnautica 2:
- Dock your Tadpole at the appropriate vehicle docking station.
- Interact with the chassis management interface.
- Select the Scout Ray Chassis from the available configurations.
- Undock the Tadpole after installation completes.
The vehicle will immediately gain the Scout Ray’s speed-focused handling profile.
What the Scout Ray Chassis actually changes
The biggest improvement is movement responsiveness. Your Tadpole becomes significantly more agile, especially when turning through tight cave systems or escaping predators.
Performance improvements
| Stat | Improvement |
|---|---|
| Top Speed | High increase |
| Turning Speed | Improved |
| Acceleration | Improved |
| Exploration Efficiency | Much better |
| Cargo Capacity | No increase |
| Passenger Support | Limited |
According to available game descriptions, the Scout Ray chassis is specifically recommended for high-threat excursions and long-distance scouting missions.
When you should use the Scout Ray instead of the Haul Chassis
The Scout Ray and Haul Chassis serve very different purposes.
| Chassis | Best Use |
|---|---|
| Scout Ray | Fast exploration and survival |
| Haul Chassis | Resource farming and storage |
If you are exploring unfamiliar zones, scanning wrecks, or navigating predator-heavy waters, the Scout Ray is usually the better option. However, if your goal is transporting resources or multiplayer utility, the Haul Chassis becomes more useful later in the game.
The Scout Ray makes exploration far safer
The Scout Ray Chassis is easily one of the strongest Tadpole upgrades currently available in Subnautica 2 Early Access. Its speed-focused design makes traveling between bases faster, navigating caves easier, and escaping dangerous wildlife far more manageable.
While it does not provide additional storage or utility slots, the movement improvements are substantial enough that many players will likely keep it equipped for most exploration-heavy gameplay sessions.
