To acquire the Docking Bay in Subnautica, you must complete certain objectives. These are:
- Construct a Moonpool on the Seabase.
- Craft a Vehicle Upgrade Console and place it inside your base.
- Craft a Cyclops hull reinforcement module, then insert it into the Vehicle Upgrade Console to unlock the blueprint for the Neptune Rocket Launch Platform.
- Use this platform to launch yourself into space and build an Alien Containment facility by collecting resources from asteroids or other planets, then return to your home planet with samples of various alien life forms. Finally build the Docking Bay!
