For example the Perth class guided missile destroyers that were built for the Royal Australian Navy in Bay City, Michigan were given the hull numbers DDG-25, DDG-26, and DDG-27; but these hull numbers were not assigned to any American destroyers after the Australian Navy had changed those to its own identification numbers.
The numbering system is mandated by the European Recreational Craft Directive and descended from the American Ship Hull number system.
