This report describes the structural design of a generic 7,600 tonne air-warfare destroyer, referred to as the DRDC Notional Destroyer (ND). The intent of the ND is to provide a test-bed for evaluating structural, stability, hydrodynamic and other naval engineering design standards, design concepts, analysis methods, and software. The ND is not based on either existing or future naval platforms. The current work is concerned only with the structural aspects of the ND design, which conforms with Lloyd’s Register’s Naval Ship Rules (NSR) for a worldwide service area. In addition to the standard Rules requirements for structures, the ND was designed against LR’s requirements for an Extreme Strength Assessment, Level 2. That entailed comparing the hull girder’s ultimate strength, as predicted using Smith’s progressive collapse method, against extreme lifetime global loads prescribed by the NSR. This Scientific Report describes the hypothetical performance requirements that drove the ND design, the modelling and analysis tools used, and the bottom-up design procedure employed by DRDC. The outcome of the design process is then presented, including the general arrangement; design loads; the final structural configuration and scantlings; and the results of the global and ultimate strength assessments. The evolution of the scantlings, from those meeting the standard NSR requirements to those meeting global and ultimate strength requirements, is discussed, as are the weight i
