In response to a request from the Australian Department of Defense (Navy), a product work breakdown (zone logic) was reintroduced into Australia in the Spring of 1988 for the benefit of the consortiums which are competing for the $5(A) dollar ANZAC Frigate Program. At the same time, this brief paper advised Australian naval architects and shipyard managers at large of the improved quality that is inherent in the application of zone logic, particularly for warships, and of what is required of designers. Special note is made of the need for professional and decentralized production engineering upon which product-oriented designers are absolutely dependent throughout all phases of the design process. A surprise for most readers, including some in Australia, is reference to the technical cooperation agreement which resulted in product-oriented shipbuilding in an Australian shipyard "a decade before" the same logic revolution started in North American shipyards.
