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.

Statistics Comparison

The table below lists default submarines and their base main characteristics; that is, before any upgrades are installed, turrets modified, or wiring tweaks made.
Maximum ascent speed (empty ballasts) is 19 km/h for all submarines. Horizontal (engine) speed is identical going forwards and backwards.

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 of course be changed to the server host's desire.

Upon spawning in the shuttle there will be fully stocked diving suits and underwater scooters, the number of spawned suits and scooters is according to the respawned player amount.

They can be used in case the shuttle is not able to dock safely to the main submarine.

Most shuttles have barely any hull, because of that they are easily sunk by most creatures, impact from rocks or other submarines. So knowing how to steer them is crucial.

Hemulen

Hemulen
	For when you need extra room to stretch your legs or want some space between you and the poor, choose Hemulen shuttles. Class: Shuttle Dimensions: 20x6 m

Selkie

Selkie
	The workhorse of the colonies, these little shuttles have good speed and dive/ascent characteristics, but they are fragile and their low-capacity batteries limit their range somewhat. Class: Shuttle Dimensions: 11x3 m

Venture

Venture
	Originally intended as research vessels, Venture shuttles have been co-opted as a more robust alternative for travel between outposts and submarines. Class: Shuttle Dimensions: 13x6 m

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 the Campaign, lost shuttles can be recovered for 1,000 mk at a Shipyard.
