List of submarines (Eurth)

This is a current list of submarines used by militaries and nations of Eurth. Ship operators with (†) denote the vessel is no longer in service. Please use the following ordering system.

• Organize first by the County of Origin (Eurth) in alphabetical order, if there are multiple countries, the primary country of origin should be used for the ordering.
• Organize in numerical or alphabetical order for Timeline of Eurth Class/Sub-class, in instances where there are both, numerical first and then alphabetical.
• Organize with the primary user in User Country/Service (i.e., the country of origin's primary service) and follow with a separate row for each different service within that country of origin. For additional users, list a new row for each user in alphabetical order.
• Try to combine as many rows as possible (e.g, Class/Subclass, Role, etc.) with rowspan="x" where applicable.

Displacement should be listed in metric tons.
