# List of auxiliary ships of the Argentine Navy

This list includes all major auxiliary ships (transports, colliers, tankers, scientific vessels, tugs, among others) in service with the Argentine Navy since being formally established in the 1860s. It does not include vessels prior to that date, nor does it include warships which are listed separately.
The list is organized by type of ship, by class within each type, and by service entry date within each class. Service entry dates indicate the ship's commissioning into the Argentine Navy, and not the ship's entry in service with another navy unless specifically said.
There is a separate list of current ships of the Argentine Navy regardless the type.

## Naming tradition

### Icebreakers and polar ships

    Antarctic coastal geographic features, or names historically related with the Argentine activity in Antarctica.

### Transports and tankers
