Auxiliary Ship

An auxiliary ship is the term used within the Union Navy for a cruiser size or smaller ship who's "home port" is a larger ship.

In most cases it's the size of a Destroyer, although some of the larger battleships may include Cruisers as part of their complement of auxiliary ships.

The Lyrec and the forty conventional battleships carried by a Karmat Class Battleship aside from their size can be classified as auxiliary ships, and in some ways that is the case. For most purposes though they are considered simply as different ships within the same "rapid reaction force" battlegroup.
