List of battleships of World War I

This is a list of battleships of the First World War. All displacements are at standard load, in metric tonnes, so as to avoid confusion over their relative displacements. [Note: Not all displacements have been adjusted to match this yet]. Ideally displacements will be as they were at either the end of the war, or when the ship was sunk.

The list includes armed vessels that served during the war and in the immediate aftermath, inclusive of localized ongoing combat operations, garrison surrenders, post-surrender occupation, colony re-occupation, troop and prisoner repatriation. Some uncompleted battleships are included, out of historic interest.
