Capital vs Auxiliary Ships
An auxiliary ship is dependent on a capital ship and the officer in charge of an auxiliary ship reports back to their assigned capital ship. For example the captain of a destroyer is typically assigned to protect a capital ship so he would report and take orders directly from the battleship he was assigned to protect. Capital ships are typically larger ships with a great deal of firepower whose very presence can turn the tide of a conflict.

Flagships
Each fleet has a flagship. This is the highest value ship that is captained by the highest ranking officer in the fleet. This is a capital ship and other capital ships typically act subserviently to the whims of the flagship.
