Ballistic Missile Defense System Space Programs
Abstract
Spacebased Kill Assessment (SKA): The SKA project will deliver dedicated space sensors contributing to hit and kill assessment for Homeland Defense. Missile Defense Agency (MDA) Missile Defense System intercept testing experience provided a solid understanding of kill assessment physics to enable exploration of this critical capability. SKA incorporates Government Accountability Office (GAO) recommendations to examine the operational feasibility of disaggregating large satellites and to provide data for the business case for shared versus dedicated satellite control, including the ground antenna networks. The favorable cost and schedule performance on SKA is also consistent with the GAO's assessment of hosted payload programs. The SKA experiment utilizes a network of small Infrared sensors integrated onto host satellites that while on orbit observe missile defense intercepts and deliver situational awareness hit and kill assessment declarations. HBTSS: HBTSS will demonstrate a schedule-focused, cost-constrained capability to detect and track hypersonic threats and boosting conventional ballistic missiles. The key characteristic of HBTSS prototype demonstration that sets it apart from other Overhead Persistent Infrared sensors is the requirement to provide fire-control quality tracking data. The enhanced tracking accuracy through missile burn out on ballistic threats and the enhanced tracking accuracy on hypersonic threats will provide the warfighter increased missile defense weapons systems engagement capability and higher accuracy impact predictions. The requirement for fire-control data necessitates that HBTSS be a highly sensitive, low-latency, high quality of service system. Following the successful demonstration of HBTSS capabilities, the responsibility for HBTSS operational fielding will be transferred to the US Space Force and the MDA will continue the development of the next-generation of space-based fire control sensors for missile defense. Operationally, the HBTSS fire-control capability will be part of Space Development Agency's Proliferated Warfighter Space Architecture and will detect hypersonic, ballistic, and other advanced threats much sooner than terrestrial radars, providing hypersonic threat-tracking data for hand off through linked missile defense weapons. Space Applications for Missile Defense (SAMD): SAMD consolidates MDA resources (including those efforts previously planned in PE 1206893C) to provide strategic planning, program integration, contracting, acquisition, engineering, financial management, and program assessments for development and acquisition of space applications. This PE also funds Cybersecurity efforts necessary to support Missile Defense System Space Programs.
