Kinetic energy weapons play a critical role in determining ballistic missile defense (BMD) system requirements. Sensor assessment of threat destruct can benefit from the capability of kinetic energy devices to induce catastrophic responses in ballistic missile targets. Similarly, thrust and maneuvering capabilities of BMD interceptors can benefit from the lessening of mass- and velocity-related lethality requirements of kinetic energy devices. The investigation underway is assessing the mass-performance of a proprietary class of advanced penetrator configurations in terms of enhanced capabilities to induce such catastrophic target responses as: blowout; gross structural failure; and/or detonation of volatile target materials. The impact, penetration and post-perforation processes are being assessed through prediction and test verification representative standard and advanced penetrator configurations are being test-fired at high velocities. Target responses also are being evaluated.
