In this presentation it is shown that high performance fuselage structures can be fabricated using advanced sheet and extruded products. New sheet fuselage products that exhibit higher strength, higher damage tolerance, better corrosion resistance and lower density than the incumbents 2x24 will be introduced.  Extruded stringers and frames that enhance the performance of the fuselage sheet will be discussed. Results from trade studies evaluating the performance improvements achievable with improved products and design will be presented. It is concluded that an all metallic fuselage can successfully compete with non-metallic alternatives
