In the frame of the Ariane 6 Program, MT Aerospace AG (MTA) is responsible for the design, analysis, test and qualification as well as for later series production of metallic bare tanks, tank components and structures of the new heavy European launcher. Due to increased launch rate and ambitious performance and cost requirements, new manufacturing processes and automated assembly technologies are key topics within the running development program using a design-to-manufacturing and a design-to-cost approach. During the last decade, MTA has developed and successfully demonstrated its competences focusing on aluminium lithium technology and friction stir welding (FSW) together with their related damage mechanics. These competences have turned into sound heritage and will now be applied for the realization of the new generation launcher Ariane 6, which will include FSW applied to all aluminium tank structures, shot peen forming performed on domes and cylinder segments made of aluminium lithium and automated riveting for the assembly of the structures. The paper describes the present design configuration for the Upper Liquid Propulsion Module (ULPM), the Lower Liquid Propulsion Module (LLPM) and the metallic skirts of the equipped solid rocket motor, together with the engineering, technology development and industrialization activities in order to deliver the products with the required performance, on time and within the costs limitations. These designs are entering the manufacturing releases of the first development and qualification models.
