DEVELOPMENT OF PERSISTENT SPACE-BASED SENSOR ARCHITECTURE.

SEC. 1683. DEVELOPMENT OF PERSISTENT SPACE-BASED SENSOR ARCHITECTURE.(a) In General.—If consistent with the direction or recommendations of the Ballistic Missile Defense Review that commenced in 2017, the Director of the Missile Defense Agency shall develop, using sound acquisition practices, a highly reliable and cost-effective persistent space-based sensor architecture capable of supporting the ballistic missile defense system.(b) Testing and Deployment.—The Director shall ensure that the sensor architecture developed under subsection (a) is rigorously tested before final production decisions or operational deployment.(c) Functions.—The sensor architecture developed under subsection (a) shall include one or more of the following functions:(1) Control of increased raid sizes.(2) Precision tracking of threat missiles.(3) Fire-control-quality tracks of evolving threat missiles.(4) Enabling of launch-on-remote and engage-on-remote capabilities.(5) Discrimination of warheads.(6) Effective kill assessment.(7) Enhanced shot doctrine.(8) Integration with the command, control, battle management, and communication program of the ballistic missile defense system.(9) Integration with all other elements of the current ballistic missile defense system, including the Terminal High Altitude Area Defense, Aegis Ballistic Missile Defense, Aegis Ashore, and Patriot Air and Missile Defense systems.(10) Such additional functions as determined by the Ballistic Missile Defense Review.(d) Cost Estimates.—Whenever the Director develops a cost estimate for the sensor architecture required by subsection (a), the Director shall use—(1) the cost-estimating and assessment guide of the Comptroller General of the United States titled “GAO Cost Estimating and Assessment Guide” (GAO–09–3SP), or a successor guide; or(2) the most current operating and support cost-estimating guide of the Office of Cost Assessment and Program Evaluation.(e) Plan.—Not later than one year after the date of the enactment of this Act, the Director shall submit to the appropriate congressional committees a plan that includes—(1) how the Director will develop the sensor architecture under subsection (a), including with respect to the estimated costs (in accordance with subsection (d)) to develop, acquire, 131 STAT. 1778 and deploy, and the lifecycle costs to operate and sustain, the sensor architecture;(2) an assessment of the maturity of critical technologies necessary to make operational such sensor architecture, and recommendations for any research and development activities to rapidly mature such technologies;(3) an assessment of what capabilities such sensor architecture can contribute that other sensor architectures do not contribute;(4) how the Director will leverage the use of national technical means, commercially available space and terrestrial capabilities, hosted payloads, small satellites, and other capabilities to carry out subsection (a); and(5) any other matters the Director determines appropriate.(f) Appropriate Congressional Committees Defined.—In this section, the term “appropriate congressional committees” means—(1) the congressional defense committees; and(2) the Select Committee on Intelligence of the Senate and the Permanent Select Committee on Intelligence of the House of Representatives.
