Vehicles are the backbone of exploration in Subnautica 2. Without them you are limited to freediving with restrictive oxygen and depth limits. Each vehicle extends your reach deeper and farther, and each fills a distinct role in your survival toolkit. Here is the complete list of vehicles and what they do.
| Vehicle | Role | How to Unlock | Base Depth |
|---|---|---|---|
| Seaglide | Personal propulsion | Scan fragments in shallows | N/A (player depth) |
| Seamoth | Fast scout sub | Scan fragments, build in Moonpool | ~200m |
| Prawn Suit | Deep mech, mining | Scan fragments in wrecks | ~400m |
| Cyclops-class Sub | Mobile base sub | Scan fragments in deep wrecks | ~500m |
The Seaglide is your first vehicle -- a handheld propulsion device that lets you swim much faster and farther than paddling. It is essential for early exploration before you have a sub. Craft it from scanned fragments found in the starting shallows.
The Seamoth is a small, fast one-person submarine perfect for scouting and mid-depth exploration. It is nimble and can be equipped with a perimeter defense system, storage modules, and sonar. Build it at a Moonpool once you have scanned enough fragments.
The Prawn Suit is a pressure-resistant mech that excels at deep diving and seabed mining. It can use a grapple arm to traverse terrain and a drill arm to harvest resources from large deposits. Its depth ceiling is the highest of any vehicle.
The Cyclops-class submarine is a large multi-person vessel that functions as a mobile base. It has interior space for fabricators, storage, and even vehicle docking. It is your endgame exploration platform for reaching the deepest zones.

How to Unlock Each Vehicle
Vehicles in Subnautica 2 are unlocked by scanning blueprint fragments scattered across wrecks and seabase ruins. Each vehicle requires a certain number of fragments to complete its blueprint, at which point you can craft it at the appropriate fabrication point. Here is how to unlock each one:
- Seaglide: Fragments are found in the shallow starting biome and nearby wrecks. You only need a few scans. Craft it at a Fabricator once unlocked.
- Seamoth: Scan Seamoth fragments in shallow-to-mid-depth wrecks. Once the blueprint is complete, craft the vehicle at a Moonpool using titanium, glass, and lubricant.
- Prawn Suit: Fragments are in deeper wrecks, often in the 200-400m range. You will need a depth-upgraded Seamoth to reach some fragment sites. Craft the Prawn Suit at a Moonpool.
- Cyclops-class Sub: Fragments are scattered across deep wrecks and larger ruins. This is a late-game unlock requiring significant exploration. Craft it at a Moonpool or specialized vehicle bay.
Carry a Scanner at all times and scan every fragment you find, even for vehicles you have already unlocked, since duplicate scans yield materials and data. Use the PDA to track your fragment progress for each blueprint.
Build a Moonpool as early as possible -- it is required to fabricate most vehicles and also serves as your upgrade station via the vehicle upgrade console. Without a Moonpool, you cannot craft the Seamoth or Prawn Suit.
Vehicle Upgrades and Customization
Upgrading your vehicles is just as important as unlocking them. Stock vehicles have limited depth and capabilities, but upgrade modules transform them into deep-diving, threat-surviving exploration machines. Upgrades are crafted at a Modification Station or the Moonpool's vehicle upgrade console.
Here are the most important upgrade categories:
- Depth Modules: Raise each vehicle's crush depth in tiers. These are your top priority for progression.
- Storage Modules: Add cargo space to the Seamoth and Prawn Suit for longer resource-gathering trips.
- Perimeter Defense: Emits a stunning pulse to repel attacking creatures. Essential for leviathan territory.
- Sonar: Maps terrain and creatures in dark water. Critical for deep and night diving.
- Hull Reinforcement: Increases vehicle health so it survives more hits before destruction.
- Engine Efficiency: Reduces power consumption for longer range between charges.
- Specialty Arms (Prawn Suit): Grapple arm for traversal, drill arm for mining large deposits, and torpedo arm for defense.
Prioritize depth modules first, then perimeter defense and hull reinforcement for survival, then convenience upgrades like storage and sonar. A fully upgraded Prawn Suit with depth modules and a grapple arm can reach the deepest biomes in the game and mine the rarest resources.
In co-op, coordinate vehicle ownership so each player has their own transport rather than sharing one sub. This prevents bottlenecks and lets the group split up for parallel exploration. Upgrade at least one vehicle to a high depth tier before the group attempts deep story content together.
