MISSION
The Missile Defense Agency (MDA) mission is “to develop and deploy a layered Missile
Defense System to defend the United States, its deployed forces, allies, and friends frommissile attacks in all phases of flight.” MDA’s budget request for Fiscal Year (FY) 2022 is$8.917 billion. MDA’s FY 2022 budget will continue the development, rigorous testing andfielding of reliable, increasingly capable, state-of-the-art defenses for the United States, ourdeployed forces, and the forces and territories of our allies and partners against current
and projected missile threats. Building on the strategy to defend the Nation, the Agency’s
foundations for missile defense are:1) Operations and Readiness;
2) Production and Fielding;3) Development and Technology.

MDA will continue to collaborate closelywith Combatant Commanders and theServices to support current and futureneeds for missile defense capabilities.
MDA and these key stakeholders leverage
the existing all-domain MDS to develop
integrated architectures and capabilities
to counter not only ballistic missiles but also hypersonic and cruise missile threats. Thisbudget request maintains operational missile defense capacity and capabilities for existing
homeland and regional defense forces and continues to increase interceptor inventory while
improving maturation of defensive technologies, existing sensors, Command and Control,
Battle Management and Communications (C2BMC) system, and kill vehicle capabilities toaddress evolving threats.
MDA’s President’s Budget submission aligns with longstanding U.S. missile defense policy,
which encourages the development and deployment of homeland missile defenses toaddress ballistic missile threats from rogue states such as North Korea and Iran. The UnitedStates is not developing or deploying missile defense capabilities designed to counter nuclear
intercontinental-range missile threats from near-peers Russia and China.
To address regional threats, U.S. missile defense policy promotes the development anddeployment of missile defense capabilities against the full range of regional missile threats
from any source, to include rogue states and near-peer adversaries. 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 cruise, ballistic, and hypersonic missiles. FY 2022
funding will support detailed engineering and analysis activities to develop and deploy aneffective defensive architecture solution.
The Ground-Based Midcourse Defense (GMD) system, currently defends the U.S. against
long-range ballistic missile threats from rogue states. Initially fielded in the early 2000s,
the GMD system is undergoing a service life extension program and will be improved with1

the addition of the Next
Generation Interceptor (NGI)
starting in 2028.
MDA continues to makesignificant progress in cybersecurity by incorporating
system-level requirements
into system specifications
and then implementing
rigorous evaluation-based
testing and assessments.
We established a Defensive
Cyberspace
Operationsorganization, augmenting
the workforce with certified
cyber teams to evaluate
the effectiveness of cyber capabilities and implement structures to enhance ourcybersecurity posture. MDA is building cybersecurity into next-generation software
processes by leveraging proven secure software development, security, and operations,and establishing continuous integration. We are also closely collaborating with our Defense
Industrial Base partners to protect MDA and supplier information. MDA defends its networks
against the advanced persistent cyber threat through its Cybersecurity Emergency Response
Team. This team provides 24/7 network monitoring and defense of over 24 thousand
network devices and continues to expand its breadth of coverage. MDA has continuously
supported DoD cyberspace efforts by providing timely MDA situational awareness.

MISSILE THREATU.S. adversaries are developing more capableballistic, hypersonic, and cruise missiles,
systems with global reach, increased speed andmaneuverability, greater accuracy, and improved
countermeasures. North Korea is developing longrange ballistic missiles that threaten the UnitedStates and our allies in the Indo-Pacific region while
also testing shorter-range maneuvering missiles.
North Korea Hwasong-15 ICBM
Iran continues to develop more sophisticatedmissiles with improved accuracy, range, and lethality. Iran is also fielding an array of
increasingly accurate short- and medium-range ballistic missiles. Iran has demonstrated theability to combine ballistic or cruise missiles with unmanned aerial vehicles in complex attacks.
Russia and China operate advanced ballistic andcruise missile forces, and they are developing
and deploying advanced air- and surfacelaunched long-range cruise and hypersonicmissile capabilities. Regional hypersonic missiles
are being developed specifically to challenge
U.S. missile defense capabilities. These threats

BUDGET ESTIMATES OVERVIEWMISSILE DEFENSE AGENCYFISCAL YEAR 2022
and partners at risk. Hypersonic glide vehicles (HGVs) delivered by ballistic missile boosters
will pose new challenges to our missile defenses. Moreover, U.S. adversaries and strategiccompetitors will increasingly use cyber capabilities to seek political, economic, and militaryadvantage over the United States and its allies and partners, including intelligence gathering
on and disruption of U.S. missile defense systems.
Major Program Element Highlights
The following discussion summarizes the highlights of major Program Elements (PE) aligned
to five broad categories: 1) Detect and Control, 2) Engage, 3) Technology, 4) MDS Testing,and 5) International. First, the system detects the launch of the threat missile and tracks
it maintaining birth to death custody of the threat. Based on this track, the Command andControl system, or C2BMC, tasks the appropriate weapon systems to engage the threat.
The weapon systems develop fire control solutions so that our interceptors engage andnegate the threat. MDA’s C2BMC is the all-domain backbone that enables detect, control,
engage sequence.

through high temperature material and seeker window characterization, as well as, nanosatellite and sounding rocket experiments and developing component technologies tosupport Missile Defense programs. In accordance with identified Agency requirements
and Warfighter needs, the program assesses and demonstrates the utility of emerging
component technologies, then facilitates transition of the technologies to the MDS. The
program also manages the selection process and administers the Missile Defense Small
Business Innovation Research (SBIR) program.
• Advanced Concepts & Performance Assessment (PE 0603176C). MDA is requesting$15.8 million in FY 2022 to centralize advanced technology concept modeling, simulation,and performance analysis. Advanced Concepts & Performance Assessments focus on the
exploration of novel and emerging capabilities that may have the potential to enhance
missile defense. The request will fund independent government assessments of industry
sensor, directed energy, and weapon system technology concepts and mature related
tracking, discrimination, and sensor fusion algorithms. Assessment activities include
development of Hypersonic Defense, Artificial Intelligence and Machine Learning
Initiatives, and Left-through-Right Integration key technology areas. The innovative
structured concept definition and assessment methodology enables MDA to validate
focus areas, verify contractor technology solutions, and evaluate promising concepts forLarge Format Fine Steering Mirror (left), and Prototype Deformable Mirror (right).

use in future missile defense architectures. This program element supports the monitoring
and tracking of cybersecurity mitigations, as well as the exploration of cyber effects on
emerging technology.
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.
IV. Missile Defense Testing• MDS Testing (PE 0603914C). MDA is requesting $362.9 million in
FY 2022. 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(DOT&E); Director, Developmental Test, Evaluation and Assessments(DTE&A); Commander, Joint Functional Component Command forIntegrated Missile Defense (JFCC IMD) representing CombatantCommands; Commander, Army Test and Evaluation Command(ATEC); Commander, Air Force Operational Test and Evaluation
Center (AFOTEC); Commander, Operational Test and Evaluation
Force (COMOPTEVFOR); and Commander, Joint Interoperability Test
Command (JITC). For flight testing, the Agency incorporates the nine
operational realism criteria defined by the Ballistic MDS Response to National Defense
Authorization Act (NDAA) Section 234, for Fiscal Year 2005, Increasing Operational Realism.
For system-level ground testing, all tests culminate in operational testing with Warfighterson console and independent operational assessments by the BMDS Operational Test Agency
Team. This ensures that MDS capabilities are credibly demonstrated and validated prior todelivery to the Warfighter.
The IMTP supports MDA’s programming strategy and test priorities. This test program captures:- New GMD Test Program and plans for testing of the NGI.
- GMD demonstrating the use of SBX Data for additional advanced Target Object
Mapping techniques, upgraded In-Flight Interceptor Communications System (IFICS)
In-Flight Data Terminal, GMD Enhanced Modem (GEM) with Exo-atmospheric Kill
Vehicle (EKV) using 2-/3- stage selectable, in 3-stage mode.
- Flight tests for SM-3 Block IIA production cut-in and the Aegis Weapon System C2BMC
using Space Domain Awareness capability.
- Increased flight test integration and interoperability testing with Allies.
- Updates on planning for cybersecurity testing through the FYDP.
- Refinements on test planning for system-level ground testing.
- Investment in the development of the Modified Ballistic Re-entry Vehicles (MBRV)
Front End for future testing.

MDA also allocates funding for hypersonic partner flight tests in FY 2022 to be identified,requirements defined, and assets de-conflicted.
• MDS Targets (PE 0603915C). MDA is requesting $553.3 million in FY 2022 to develop,
produce, and launch an economical and reliable inventory of targets based on engineering
assessments of threat intelligence data. This funding enables the test, verification, andvalidation of the performance of the MDS against threats in support of the IMTP, andincludes funding for the continued development of Advanced Targets, and development
and production of more reliable and capable MRBM Target motors with enhanced
maneuverability and range.

V. International• Israeli Programs. MDA is requesting $500 million for Israeli
programs in FY 2022. This funding level remains consistent
with the Memorandum of Understanding between the
United States and Israel that spans FY2019 – FY2028. Thisbudget continues MDA's longstanding support of U.S.-Israeli
Cooperative Programs, to include the co-development andco-production of the David's Sling Weapon System and theArrow Weapon System. The Department continues to support
co-production efforts for the Iron Dome Defensive System
program to provide critical defense against short-range rockets
and missiles, mortars, and artillery shells, and new capabilities
against Unmanned Aerial Vehicles. In FY 2022, the MDA
budget will also support several flight tests across the Israeli
portfolio. These continued joint efforts provide Israel with athree-tiered defense to defend itself from ballistic missiles,
rockets, and cruise missiles and ensures Israel maintains its
qualitative military edge against its advisories.
