Subnautica 2 Vehicles — All Current and Upcoming Submersibles

How many vehicles are in Subnautica 2 right now?

If you are searching for "all vehicles in Subnautica 2", the confusing part is that databases and player discussions often mix together vehicles, chassis, build stations, and future placeholder content. If the question is "what can I actually unlock, craft, and drive right now?", the current answer is the Tadpole. It is the mini-submersible shown on the official Steam page and the vehicle that carries most of the current Early Access exploration loop.

That does not mean the vehicle system is empty. The Tadpole changes role through chassis choices, depth modules, and upgrades. You can tune it toward hauling resources, faster scouting, safer deep dives, or longer battery life. In practical terms, current Early Access is built around one core submersible with multiple configurations, rather than a fleet of several independent submarines.

Current Vehicle Status

Name	Status	What it is	Best guide
Tadpole	Unlockable, craftable, drivable	Main single-seat submersible	Tadpole guide
Tadpole Haul Chassis	Used as a Tadpole chassis	Cargo, transport, expedition prep	Chassis options
Scout Ray Chassis	Used as a Tadpole chassis	Speed, acceleration, handling	Chassis options
Seafrog Chassis	Do not treat as currently available	Future or unopened chassis variant	Tadpole status
Trident	Not currently craftable or drivable	Future large multi-crew submarine	Trident status
Vehicle Fabricator	Buildable	Base station for vehicles, not a vehicle	Fabricator guide

Tadpole: the main playable vehicle

The Tadpole is the step that moves you from swimming and Seaglide travel into real vehicle exploration. It gives you a protected hull, a power system, upgrade slots, and enough range to plan dives instead of constantly returning to the surface. PC Gamer's tested Tadpole guide confirms the practical flow: scan Tadpole fragments, build the supporting vehicle facilities, then use the Vehicle Fabricator and Tadpole Dock to make the submersible part of your base routine.

The default Tadpole is useful on its own, but its upgrades are what make it central. Depth modules open deeper routes; engine efficiency stretches battery life; a cavitation muffler helps reduce noise and predator attention; photovoltaic charging helps in shallow daylight travel. If your real question is "which vehicle should I build first?", the answer is simple: build the Tadpole, then get the depth module and the chassis that matches your next objective.

Chassis options are not separate submarines

The Haul Chassis and Scout Ray Chassis are often counted in "all vehicles" lists because they change how the Tadpole handles. That is fair for a search page like this, but they should not be described as two extra complete submarines. They are Tadpole configurations. You still plan around one vehicle body, then swap or build the chassis that fits the job.

Configuration	Use it for	Best fit
Standard Tadpole	Daily exploration, first deep dives, story routes	Players who just unlocked vehicles
Haul Chassis	Mining runs, material transport, long supply trips	Base builders and resource farmers
Scout Ray Chassis	Fast map traversal, fragment scans, evasive movement	Explorers who value speed and handling

Can you use the Trident or Seafrog now?

No, you cannot build or pilot the Trident in the current Early Access build. Treat it as a future large-submarine target, not a current progression step. Our Trident page tracks why it appears in some databases and why it is discussed as a later multi-crew submarine, but you should not plan your current save around crafting it.

Do not treat the Seafrog Chassis as a normal current unlock either. For a standard survival route, your reliable choices are the Tadpole, its depth upgrades, the Haul Chassis, and the Scout Ray Chassis. If a page claims that you can already unlock a Trident recipe or reliably build Seafrog in the live survival path, check its date and source. Early Access changes quickly, and placeholder data can be mistaken for live content.

Recommended Build Order

To go from "I know every vehicle name" to actually using vehicles efficiently, follow this order. First, follow black box and habitat leads until you can scan the relevant blueprints. Second, build a powered starter base with the Vehicle Fabricator. Third, craft the Tadpole. Fourth, prioritize Depth Module Mk.1 so the vehicle is not limited to shallow routes. Fifth, decide whether your next problem is cargo capacity or speed, then choose Haul or Scout Ray accordingly.

For co-op groups, the Tadpole is still the practical first vehicle even though Subnautica 2 supports up to four-player online co-op. A larger future submarine will make more sense for shared expeditions once it is implemented, but current progression rewards a team that divides resource gathering, base power, charging, and repair prep around Tadpole use.
