## What project B1K buys

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. Capability Development/Modernization 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. In addition, 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. 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 Project Office. Details are provided under separate cover. THAAD Test conducts Missile Defense System Flight Tests and Ground Tests with other Missile Defense System elements in accordance with the Integrated Master Test Plan (IMTP). THAAD Test coordinates with Operational Test Agencies, conducts all pre and post flight test, ground test, testing of cyber security enhancements, and wargames and exercises requirements.

**R-3 lines of work:** Management Services; Product Development; Support; Test and Evaluation.

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
