As　a　crucial　weapon　in　the　sea　battle,anti-ship　missiles　generally　employ　a　sea-skimming　penetration　strategy　to　reduce　the　probability　of　being　detected　by　the　target　radar,which　greatly　increases　the　risk　of　touching　water　caused　by　sensor　errors　or　random　sea　conditions.To　alleviate　the　large　impact　load　by　high-velocity　water　touching,a　novel　anti-ship　missile　body　configuration　is　proposed　in　this　paper,which　is　inspired　by　the　idea　of　hydroplaning.A　parametric　geometry　model　is　first　developed　to　modify　the　configuration　of　the　anti-ship　missile　body.Subsequently,a　structured　arbitrary　Lagrange-Eulerian　based　Fluid-Structure　Interaction(FSI)model　is　estab-lished　to　analyze　the　kinematics　parameters　of　the　missile　body　during　the　hydroplaning　process.A　missile　body　configuration　optimization　problem　is　then　formulated　to　minimize　the　impact　load　considering　several　constraints,e.g.,horizontal　velocity　loss,pitch　angle　after　touching　water,and　inside　capacity　for　payload.Due　to　the　time-consuming　FSI　simulation,a　Kriging-assisted　con-strained　differential　evolution　method　is　utilized　to　optimize　the　missile　body　configuration　for　reducing　the　impact　load.During　the　optimization　process,radial　basis　function　and　Kriging　are　combined　with　evolutionary　operators　to　lead　the　search　to　the　vicinity　of　the　optimum　rapidly.The　result　shows　that　the　proposed　missile　body　configuration　can　reduce　the　impact　load　by　18.8％compared　with　the　ordinary　configuration.Additionally,the　optimized　configuration　can　further　yield　a　17.4％impact　load　decrease　subject　to　all　the　constraints　and　avoid　structural　dam-age　by　the　high-velocity　water　touching,which　demonstrates　the　effectiveness　and　practicability　of　the　proposed　anti-ship　missile　body　configuration　and　corresponding　optimization　framework　for　reducing　the　impact　load.
