The weather shield of a naval gun weapon system is an element of fundamental importance in the operational life of the gun, since it guarantees a defense from the environment (i.e. thermal effects, rain, corrosion, green water load, etc.) in the operational conditions (i.e. protection against electromagnetic interferences, RCS reduction, etc.). This thesis concerns the design, the construction of a prototype, the qualification, and the industrialization of a weather shield for naval gun system MK 71 MOD 2. The aim of the thesis is to make the student acquire a working method in the design through participation in all phases of product development including not only the aspects of calculation and drawing, but also the economic aspects (budgeting, production costs, etc..), safety, ergonomics, logistics, workshop and even after sales. At the moment, the naval guns that mount MK 71 MOD 2 shields are in an aluminum sandwich structure. The redesign was necessary to solve the problems listed below in order of importance. It will solve the problems observed in the field of aluminum shields. The new product is very innovative in type of structure, materials, and construction technologies. The stages of development are the following: -comparison of the materials with which the shield of a naval cannon can be made in order to identify the most suitable and innovative ones and identify construction technologies; -complete design (feasibility study, FEM calculation, construction and assembly drawings, optimization of ergonomics and logistics); -design and construction of production equipment (models, molds, drilling masks, etc.).); -construction of the prototype and preparation of production documentation; -qualification activities, including qualification plan, procedures and qualification dossiers; -industrialization, consisting in the introduction into the data package of all modifications made to the shield and equipment during the construction of the prototype; -all the documentation required by the customer in the requirement.
