Hyper-Velocity Projectile (HVP) Warhead Optimization for Lethality

General Sciences, Inc. (GSI) and Lockheed Martin (L/M, Valley Forge, PA), as a subcontractor, propose to incorporate solid-state exothermic composites and structures into the Hyper Velocity Projectile (HVP) to provide lethality enhancement in a non-hit-to-kill as well as a hit-to-kill option. The enhancement is based on the better coupling of the chemical as well as the kinetic energy inside the target generating higher temperature, pressure and projectile fragmentation resulting into a catastrophic event in the target interior, damaging both soft parts as well as thicker wall munitions cases. The reactive structural material proposed has a density of 8g/cm3 and a compressive strength of 55,000psi previously used successfully in the defeat of 82mm mortar of foreign origin. This material can be used in a blast fragmentation, non-hit-to-kill or a hit-to-kill option. The proposed part insertion/substitution concept will be subjected to several risk reduction ballistic experiments demonstrating projectile survival at 30,000 g, using targets ranging from carbon phenolic Re-Entry Vehicle (RV) heat shield to RV internal parts (electronics and munitions). L/M will provide innovative payload designs including reactive part substitution, maximizing the HVP warhead lethality against ballistic, cruise and air defense missile threat using codes available from previous and current HVP contracts.
