MISSION
The Missile Defense Agency (MDA) mission is to develop and deploy a layered integrated
missile defense system to defend the United States, its deployed forces, allies, and friends
from missile attacks in all phases of flight. The MDA designs, develops, and delivers
capabilities through the Services to meet Combatant Command joint requirements,
while also sustaining advanced missile defense systems as part of the fully integrated andlayered missile defense system.
MDA’s budget request for Fiscal Year (FY) 2024 is $10.9 billion. The FY 2024 budget willcontinue the development, rigorous testing and fielding of reliable, increasingly capable,
advanced missile defenses. The Agency’s priorities for missile defense are:1) Operations and Readiness,
2) Production, Fielding, andDeployment, and
3) Technology, Development,
and Test

MDA will continue to collaborateclosely with Combatant Commanders(CCMDs) and the Services to support
current and future needs for missile
defense capabilities. MDA and these key stakeholders are leveraging the existing alldomain missile defense system to develop integrated architectures and capabilities
to counter the evolving missile threat from ballistic, hypersonic and cruise missiles.
This budget request maintains operational missile defense capacity and capabilities forexisting homeland and regional defense forces; increases interceptor inventory andmaturation of defensive technologies; and improves existing sensors and the Command
and Control, Battle Management and Communications (C2BMC) system.
In accordance with the National Defense Strategy, the Missile Defense Review, and the
Defense Planning Guidance, MDA’s budget includes funding for improving homelandballistic missile defense architectures to protect against intercontinental ballistic missile(ICBM) threats from North Korea and potentially Iran. This budget also continues
investment in regional missile defense capabilities to defend forward deployed forces inpartnership with friends and allies.
In the regional context, United States (U.S.) missile defense policy promotes thedevelopment and deployment of missile defense capabilities to counter the full range ofregional missile threats (e.g., advanced ballistic, hypersonic, and cruise missiles) from any
nation of origin, to include advanced regional missile threats from the People’s Republicof China and Russia. In response to increasing threats in the Indo-Pacific region, MDA
is supporting efforts to improve the Warfighter's capability to defend Guam against
regional ballistic, and cruise missiles. FY 2024 funding will support activities to continue
development and deployment of an effective defensive architecture solution.

MISSILE THREAT
Missile threats continue to increase, growing more numerous and complex. Adversary
missile systems are becoming more mobile, survivable, reliable, and accurate while
also achieving longer ranges. Hypersonic glide vehicles delivered by missile boosters
are an emerging threat that pose new challenges to missile defense systems. Adversary
missile pre-launch survivability is likely to increase as potential adversaries strengthen
their denial and deception measuresand increasingly base missiles on mobile
platforms. Increasing technical andoperational countermeasures continue tochallenge defensive systems in missiles.
New missile systems feature multiple
independently targetable reentry vehicles
and maneuverable reentry vehicles, alongwith decoys and other countermeasures.
Ballistic and maneuvering missile threats
continue to increase with the advancement Russian ship launches Tsirkon Hypersonic Cruise
and proliferation of missile technology.
Missile (HCM).
As demonstrated recently by Russia in Ukraine and attacks on both the Kingdom of
Saudi Arabia and the United Arab Emirates, missiles continue to be a primary tool foradversaries in times of conflict. Russia and China are developing advanced cruise missilesthat can be launched from air, maritime, and land-based platforms. Maneuvering
missiles, such as hypersonic glide vehicles, provide a challenge to existing defensive
systems because they can travel on unpredictable flight paths at low altitudes making
them difficult to track using standard terrestrial radar systems. Consequently, thecontinued investment in development of long range and resilient sensor technologies

IV. Missile Defense Testing
MDA plans and executes a fully integrated test program that synchronizes the system
under test with the Warfighters trained to operate the system under varying wartime
conditions against current and emerging threats. The Integrated Master Test Plan
(IMTP) documents our rigorous test program (flight, ground, cyber, wargames, andexercises). MDA structures its test program to improve confidence in the missile defense
capabilities under development and to ensure the capabilities transferred to the
Warfighter are operationally effective, suitable, and survivable.

• Missile Defense System Testing (PE 0603914C). MDA is requesting $360.5 million
in FY 2024. MDA conducts regular intercept flight tests. These tests provide data
to anchor models and simulations that can then be used to verify performanceand confirm the technological progress of the Missile defense system against
missile threats. MDA also conducts regular, rigorous non-intercept tests, including
sensor characterization flight tests, ground tests, cybersecurity and resiliency
tests, wargames, and exercises. Developed in collaboration with stakeholders, the
IMTP identifies and incorporates all testing requirements into a comprehensive,highly integrated, cost-effective series of flight tests, ground tests, cybersecurity
tests, exercises, and wargames. IMTP Stakeholders, who are also signatories,
include: Director, Operational Test & Evaluation; Director, Developmental Test,
Evaluation and Assessments; Commander, Joint Functional Component Commandfor Integrated Missile Defense representing CCMDs; Commander, Army Test and
Evaluation Command; Commander, Air Force Operational Test and Evaluation
Center; Commander, Operational Test and Evaluation Force; and Commander, Joint
Interoperability Test Command. For flight testing, the Agency incorporates nine
operational realism criteria. For system-level ground testing, all tests culminate
in operational testing with Warfighters on console and independent operational
assessments by the missile defense system Operational Test Agency Team. This
ensures that missile defense system capabilities are credibly demonstrated andvalidated prior to delivery to the Warfighter. The IMTP supports MDA’s programming
strategy and test priorities. This test program captures:- Sea-Based Terminal Increment 3 simulated Aegis BL9.2.4/SM-6 engagement
against a hypersonic glide vehicle.
- Sea-Based Weapon System Midcourse performing a target scene data collect of a
medium range ballistic missile (MRBM) with countermeasures.
- 3-Event Flight Test Campaign for THAAD to assess TH 4.0 Global software capability
to detect, track, and discriminate SRBMs with countermeasures (CMs). Each
event will feature a target with different CMs; no interceptors will be launched.
Also, the event will demonstrate interoperability with Patriot by exchanging Link16 messages (supports Increment 6C/7).
- Annual interoperability and integration flight testing with Patriot.
- Increased flight test integration and interoperability testing with Allies, including
support for Pacific Dragon Live-Fire Exercise- Refinements on test planning for system-level ground testing.
- Updates on planning for cybersecurity testing.
- As part of the overall MDA Test budget request, MDA is requesting $15.0 million
in FY 2024 for the Defense of Guam. Funding will provide for the initial flight andground testing of the Defense of Guam architecture to achieve developmental
and operational test objectives to deliver data for capability assessments andfielding. Funding directly supports the first flight test for the Aegis Guam Weapon
System tracking of a Medium Range Ballistic Missile target.

in FY 2024 to develop, produce, and launch an economical and reliable inventory oftargets based on engineering assessments of threat intelligence data. This funding
enables the test, verification, and validation of the performance of the missile
defense system against threats in support of the IMTP, and includes funding for thecontinued development of Advanced Targets, and development and production of
more reliable and capable MRBM Target motors with enhanced maneuverability andrange. As part of the overall MDA Targets budget request, MDA is requesting $53.0
million in FY 2024 to provide targets required for testing related to the Defense of
Guam. This funding will provide non-recurring engineering and hardware for thedevelopment of the Hypersonic Test Vehicle (HTV) flight test re-entry vehicle.
• Ground Test Facility Infrastructure (GTFI). MDA is requesting $148.0 million of Military
Construction (Major MILCON) to support the relocation of critical missile defense
system assets from off-post lease space to the Von Braun Complex.
V. Israeli Programs
MDA is requesting $500 million for Israeli
programs in FY 2024. This funding levelremains consistent with the Memorandumof Understanding between the UnitedStates and Israel that spans FY 2019 –FY 2028. This budget continues MDA's
longstanding support of U.S.-Israeli
Cooperative Programs, to include
the co-development and co-productionof the David's Sling Weapon Systemand the Arrow Weapon System. The
Department continues to support coproduction efforts for the Iron DomeDefensive System program to provide
