Analysis on damage of anti-ship missile warhead under close explosion

  Objectives  In terms of short-range anti-missile small-caliber guns, the explosive power field of an anti-ship missile warhead and its damage to large-scale surface ships has always been a concern.

  Methods  Based on the theoretical analysis and crushing test of the projectile, a model of the explosive power field of the Harpoon anti-ship missile warhead is established. Considering the relative position, velocity and flight attitude of the missile, a damage bearing model is established. Through an analysis of the vulnerability of typical ships, an equivalent target model for large surface ships is obtained.

  Results  Based on the calculation and analysis, the damage threat distances of explosion shockwaves and fragments are obtained for warship structures, shipboard fixed wing aircraft, warship surface equipment and crew.

  Conclusions  The established model and calculation method can realize the quantitative analysis of the threat of Harpoon anti-ship missile close-range explosion damage, Providing a basis and technical support for related research.
