Ballistic Missile Defense Terminal Defense Segment

The THAAD system provides a capability to intercept and destroy short-range, medium-range, and limited intermediate-range missile threats inside or outside the atmosphere during the terminal phase of flight. THAAD continues the development and integration of multiple, independent system builds to address the evolving threat, improve reliability, availability and readiness, defense planning, and improved capability to engage Short-Range Ballistic Missile, Medium-Range Ballistic Missile, and limited Intermediate-Range Ballistic Missile threats. THAAD Development executes the iterative development and integration of multiple, independent system builds to deliver enhanced system capabilities and expand the defense of allies and deployed forces from short to limited intermediate-range threats and the integration of the THAAD weapon system into the Army IBCS architecture. Program Operations provides strategic planning, program integration, cost estimating, contracting, financial management, internal reviews and audits, earned-value management, and program assessments for the THAAD Program Office. Project Redwood details are provided at a Higher Classification reported in accordance with Title 10, United States Code, Section 119 (a)(1) in the Special Access Program Annual Report to Congress. THAAD Program Support provides communications and interoperability efforts to support the Materiel Release process, maintaining safety and mission assurance and enabling the ability to operate on multiple networks. Beginning in FY 2027, the responsibility for THAAD Research, Development, Test and Evaluation funding will transfer to the Army to support ongoing development of the THAAD weapon system. This transfer consolidates THAAD resources under Army management, reflecting a realignment of responsibilities and ensuring future requirements are planned and resourced directly within the Army.

Cyber Operations sustain the Missile Defense Agency (MDA) Risk Management Framework (RMF) and Controls Validation Testing (CVT) activities; analysis of validation results, risk assessments; reviews of proposed Program Manager/Information Assurance Manager Plans of Action and Milestones for MDA Terminal High Altitude Area Defense (THAAD) mission systems; and supports THAAD authorizations to operate in the Missile Defense System. Beginning in FY 2027, the responsibility for THAAD Research, Development, Test and Evaluation funding will transfer to the Army.

PWS contains non-headquarters management costs in support of Missile Defense Agency (MDA) functions and activities across the entire Missile Defense System. These functions include Government Civilians and Contract Support Services. This effort provides integrity and oversight of the Missile Defense System as well as supports MDA in the development and evaluation of technologies that will respond to the changing threat. Additionally, PWS includes personnel to support global deployments performing deployment site preparation and activation, and provides facility capabilities for MDA Executing Agent locations worldwide. Other MDA wide costs include: physical and technical security; civilian drug testing; audit readiness; the Science, Technology, Engineering, and Mathematics (STEM) program; legal services and settlements; travel and agency training; office, equipment, vehicle, and warehouse leases; utilities and base operations across multiple geographic locations; commercial and ancillary facility services; management of all facility aspects regardless of lifecycle stage; supplies and maintenance; compliance with statutory environmental requirements; data and unified communications support; materiel and readiness and central property management of equipment; Facilities Sustainment, Restoration and Modernization (FSRM) program (formerly Real Property Maintenance) to keep the Department's inventory of facilities in good working order; and similar operating expenses. PWS is allocated on a pro-rata basis across most Agency PEs and, therefore, fluctuates per PE by FY based on the total Agency budget in that FY.
