Submarines are the central feature of Barotrauma. They are used to navigate Europa's vast oceans while keeping their crew safe from the moon's many dangers.
The crew's main task is to maintain the various Installations in working order and fight fires and floods.

Shuttles

Shuttles are much smaller submarines used mostly as respawn vessels in multiplayer. They very often don't have their own nuclear reactor and their batteries are often fully charged and can store more kW power than the main submarine.
Respawn shuttles spawn only if a certain percentage of players has died. This can be changed in the server's settings.

Upon spawning in, the shuttle will be stocked with Disposable Diving Suits equal to the number of respawned players on board.
They can be used in case the shuttle is not able to dock safely to the main submarine.

Shuttles are incredibly prone to sinking from attacks, given that they have no turrets and little hull health compared to normal submarines.

Drones

Drones are small shuttles, remotely controlled from the submarine using a Shuttle Navigation Terminal.
They are battery powered, and extremely fragile. They are not made to transport humans or cargo. Their task typically is to provide remote scouting and firepower.
Two default submarines have their own shuttle: the Remora and the Kastrull.

In Campaign mode, lost shuttles can be recovered for 1,000 mks at an Outpost.
