What is the Missile Defense Agency (MDA)?
The MDA is a United States government agency within the Department of Defense (DoD). It is made up of federal government civilians, military members from all services, and support contractor personnel. Our mission is to develop and field an integrated, layered, ballistic missile defense system to defend the United States, its deployed forces, allies, and friends against all ranges of enemy ballistic missiles.—short, medium, intermediate and intercontinental.
Since receiving presidential direction in December 2002, the DoD and the Missile Defense Agency has delivered an initial defensive capability to the warfighter while continually developing a more technically sophisticated system to stay ahead of the evolving ballistic missile threat. In the next few years, the Agency intends to deliver significantly more integrated and robust missile defense technologies.
Why is the United States developing a missile defense capability?
The United States is developing the Ballistic Missile Defense System to counter the threat ballistic missiles pose to the United States, its deployed forces, allies, and friends. The ballistic missile threat continues to grow in size and complexity. This evolving threat is multi-faceted.
What is the nature of the ballistic missile threat?
The threat is increasing in both quantity and quality. Quantitatively, many nation-states with missiles are increasing their inventories. At the same time, a growing number of states are deploying missiles with greater capabilities.
More nation-states are moving to advanced liquid-propellant systems and even to solid-propellant systems. These systems have increased flexibility, mobility, survivability, and reliability. Ranges are increasing, putting ever more potential targets at risk.
What and who are the existing and near-term emerging threats to Europe?
A phased adaptive approach for missile defense in Europe is based on an assessment of the Iranian missile threat and a commitment to deploy technology that is proven, cost-effective, and adaptable to an evolving security environment. The intelligence community assesses that the threat from Iran's short- and medium-range ballistic missiles is developing rapidly threatening U.S. allies, partners and U.S. deployed personnel−military and civilian−and their accompanying families in the Middle East and in Europe.
What is the current timeline for implementing the Phased Adaptive Approach in Europe?
U.S. ballistic missile defense assets are currently deployed as part of Phase I of the European Phased Adaptive Approach (EPAA). Phase II, planned for the 2015 timeframe, and Phase III, planned for the 2018 timeframe, are on track for completion in their planned timelines.
How can I learn about the Ballistic Missile Defense System (BMDS)?

If you still have questions, check out the BMDS FAQs.
What kind of testing does the MDA do?
The Missile Defense Agency (MDA) executes a rigorous test program that includes testing against short-, medium-, intermediate-, and longer-range threats. The MDA has consistently pursued a comprehensive and integrated approach to missile defense testing and is gradually making tests more complex. Missile defense testing will continue to enable developmental and operational test authorities, with warfighters, to assess Ballistic Missile Defense System (BMDS) performance in operationally realistic conditions.
Testing also builds the confidence of U.S. and allied stakeholders in the BMDS, bolsters deterrence against missile development, and sends a powerful message to potential adversaries looking to acquire ballistic missile technology.

What is the mission of the Aegis Ballistic Missile Defense (BMD) Program?
Aegis BMD’s mission is to deliver an enduring, operationally effective, supportable and integrated ballistic missile defense capability in Aegis cruisers and destroyers, in defense of the U.S., deployed forces, allies and friends; to increase the effectiveness of the Ballistic Missile Defense System (BMDS) by contributing to the synergy with other BMDS elements; and to incrementally increase this capability by delivering evolutionary spiral upgrades as part of BMDS development. Since 2004, the operational Aegis BMD Weapon System has included an engagement capability against regional ballistic missile threats providing the BMDS with its first mobile, global, deployable and proven capability that can destroy ballistic missiles above the atmosphere. The Aegis BMD system integrates with other parts of the BMDS, receiving and providing track information to expand battlespace and improve effectiveness.
Is the Aegis BMD capability deployed?
Installation, equipping and crew training is ongoing. The initial stage has been to outfit 18 Aegis ships with the capability, fifteen destroyers and three cruisers. Sixteen of these were in the Pacific and two in the Atlantic.
Will more ships be equipped?
In response to the increased demand for Aegis BMD capability from the operational forces (Central and Europe Commands), the Missile Defense Agency (MDA) and the U.S. Navy have commenced a joint initiative to increase the number of Aegis BMD Atlantic Fleet ships to five by January 2010. In response to the Combat Commanders’ demand, Secretary of Defense added funds to modify six more Aegis ships to conduct BMD operations in the defense budget, thus bringing the near-term level to 11 equipped ships in the Atlantic and 16 in the Pacific. The Navy’s Modernization Program will add even more BMD capable ships starting in the next few years.
Will the SM-3 missile be available for international sale?
Yes. Japan first purchased the Aegis BMD system in 2003. Presently, all four of Japan’s KONGO Class Destroyers will be upgraded with the Aegis BMD Weapon System and SM-3 missiles. Two installations have been completed and the remaining installations are scheduled through 2010.
Will allies, especially Japan, contribute to production costs for the missiles?
Foreign Military Sales rules require the allied international customers to pay the full cost of the items procured. An increase in procurement quantities would ultimately lower unit production costs and benefit the U.S. government.
What is happening with the ALTB Program?
The MDA is transitioning its Directed Energy Research program from ALTB test to development of a next-generation airborne platform for missile defense missions. The ALTB program accomplished its key MDA Knowledge Point when it successfully shot down a boosting missile in February 2010 and completed the contract in November 2011. Recently, classified hardware and laser chemicals were removed from the aircraft as part of its preparation for storage.
What will happen to the aircraft?
The aircraft will be processed into storage at the 309th Aircraft Maintenance and Regeneration Group, Davis-Monthan AFB, Arizona. The aircraft will be screened in accordance with Department of Defense procedures for reutilization and possible display at a Government installation or private museum.
If the program had completed the contract, what work was being done when the President's 2012 Budget constrained the operations?
After shoot down, the program transitioned to Science & Technology testing to demonstrate extended range tracking and measure the effects of jitter and the boundary layer on beam propagation. The program had two contracts in place in November 2011, one for continued testing and one for storage preparation. In consideration of the reduced funds to the Directed Energy Program Element, MDA began program closeout and awarded the storage contract.
What will happen to the Science and Technology testing now?
The remaining Science and Technology objectives will be accomplished by other Service and Agency programs as needed to support their requirements.
How much money was spent on the program?
Total funding appropriated to the program since the Missile Defense Agency took it over in fiscal year 2002 through fiscal year 2011 is $4.1B.
What did we get from our investment in the ABL/ALTB?
The ABL/ALTB built and tested the world's first airborne megawatt-class laser and demonstrated the ability to acquire and track a boosting missile, actively compensate the high energy laser for atmospheric distortions, and place a stabilized laser spot on a boosting missile over hundreds of kilometers. The program then demonstrated the laser kill of a solid fueled boosting missile and destruction of a representative foreign ballistic missile in flight and verified these accomplishments by placing and measuring lethal energy on instrumented missiles in flight. These accomplishments demonstrated the viability of a directed energy weapon for missile defense.
What's next for Directed Energy research to support missile defense?
The MDA is developing highly efficient electric lasers that, when combined with the potential benefits of operation on high altitude, low-mach airborne platforms will significantly reduce the complexity and cost of future directed energy weapons. In parallel with laser development, a high-altitude platform test program will verify high altitude flight characteristics and provide data to concept development of the next-generation airborne platform for missile defense missions.
What role do sensors play in the BMDS?
Sensors play a critical role in identifying, classifying and communicating ballistic missile threats for boost, midcourse and terminal intercept assets.
What is the difference between infrared and phased-array radars?
Infrared sensors on the ground, in aircraft, or on spacecraft can detect hot spots like motor-vehicle engines, jet engines, missile exhausts and even campfires—but must be 'looking' in the direction to gather the information. They have good location accuracy and high sensitivity to signals without registering false targets such as sun reflections.
Phased-array radars operate with antenna radiation patterns and are widely used in communications, defense, and space applications. Phased-array radars use a large number or individual elements 'arrayed' on a radar face; some systems use a single face, others use multiple faces. Like a mechanical antenna, each individual element can both transmit and receive. These functions are controlled electrically by timing or 'phasing' the signal to each element. While some phased-array radars are fixed, systems like the Aegis system have a fixed-array that is mounted on a ship and is a mobile radar.
Are these just satellites?
No. The sensor layer for the BMDS will consist of several different types of sensors. These are; Overhead Persistent Infrared, UAV-Based Sensors, Space Tracking & Surveillance System, Sea-Based Radars, Upgraded Early Warning Radar, COBRA DANE radar, Midcourse X-Band Radar, AN/TPY-2 Radar and the SPY-1. For more information, please look at the Sensors page.
Are these sensors in place right now?
Some are currently active and some are still coming online in the near future.
Currently, the Overhead Persistent Infrared uses existing satellite technology to collect, process and communicate data for missile warning and defense.
Unmanned Aerial Vehicles-based sensors are in place and used to protect U.S. forces and allies in forward deployed areas against ballistic missile attack by identifying and communicating threats.
Sea-Based Radars consist of the operational Sea-Based X-band radar mounted on a mobile platform and Aegis ships. The SBX is able to detect, acquire, and track targets to provide data necessary to classify and engage. The SBX is a unique combination of advanced X-band radar with a mobile, ocean-going, semi-submersible platform that provides the BMDS a sensor capability that can be positioned to cover any part of the globe. Aegis destroyers detect and track ICBMs and report track data to the missile defense system. This capability shares tracking data to cue other missile defense sensors and provides fire control data to Ground Based Midcourse Defense (GMD).
Space Tracking & Surveillance System is planned to be a constellation of low-earth orbiting satellites that will provide a global capability to detect and provide critical tracking information about ballistic missiles. The system will provide end-to-end tracking, discrimination of warheads and decoys and transmission of data to other systems to cue radars and intercept assets. STSS will also be able to provide hit/kill assessments to process and improve BMDS intercepts.
There are three operational Upgraded Early Warning Radars (UEWR) using solid state, phased-array surveillance operating from Beale Air Force Base in California, Thule Air Base, Greenland, and RAF Fylingdales in the United Kingdom and an operational COBRA DANE Radar at Shemya, Alaska. The UEWR's provide integrated tactical warning and attack assessment as well as providing estimated launch and impact points. These radars operate in the Ultra High Frequency Band and can detect objects out to 3000 miles.
How does THAAD support the Ballistic Missile Defense System?
The THAAD element provides the Ballistic Missile Defense System with a globally transportable, rapidly deployable capability to intercept and destroy ballistic missiles inside or just outside the atmosphere during their final, or terminal, phase of flight.
What is THAAD?
A THAAD battery consists of four main components: truck-mounted launchers, interceptors, radar, and fire control/communications. THAAD is a mobile interceptor missile designed to intercept short- to medium- range ballistic missiles inside or just outside the earth's atmosphere. The interceptor is a single-stage round consisting of a solid propellant booster and a kill vehicle encased in a canister.
How does THAAD work?
The interceptor is launched from a truck-mounted, palletized loading system designed launcher. Interceptor steering before booster burnout is provided by an electromechanical Thrust Vector Actuation (TVA) System. The TVA System vectors the solid rocket booster nozzle based on commands given by the missile mission computer. After booster separation, a separate group of several small thrusters make the kill vehicle turn and roll toward the target. The interceptor has autonomous on-board navigation, refines navigation using in-flight target updates and acquires, tracks and intercepts the target.
The THAAD element uses hit-to-kill technology whereby kinetic energy destroys the incoming warhead. The high-altitude intercept mitigates effects of enemy weapons of mass destruction before they reach the ground.
Is THAAD currently fielded?
Production of THAAD began in December of 2006. The first two THAAD batteries were activated by the U.S. Army in May 2008 and October 2009. A third THAAD battery was delivered in 2013 and began training. Production of THAAD continues with a total planned procurement of six batteries. The U.S. Army is responsible for deployment and operations.
How is THAAD deployable?
A THAAD battery is rapidly deployable by being globally transportable via air, land and sea.
What type of radar is included in the THAAD Battery?
The Army-Navy/Transportable Radar Surveillance and Control (AN/TPY-2) is the largest air-transportable X-band radar in the world. It searches, tracks, and discriminates objects and provides updated tracking data to the THAAD interceptor.
What is a THAAD launcher?
The THAAD launcher is one of the four main components of a THAAD battery. The launcher is truck-mounted, highly-mobile, and able to be stored. The launcher can hold eight interceptors which can be fired and rapidly reloaded.
How does the fire control work?
The fire control is also one of the four main components of a THAAD battery. The fire control is the communication and data management backbone which links the THAAD components together. The fire control also links THAAD to external command and control nodes and to the entire Ballistic Missile Defense System. The fire control plans and executes intercept solutions.
What is the Ground-based Midcourse Defense program about and how does it work?
What is Ground-based Midcourse Defense (GMD)?
The GMD element of the Ballistic Missile Defense System (BMDS) employs integrated communications networks, fire control systems, globally deployed sensors and Ground-Based Interceptors (GBI) that are capable of detecting, tracking and destroying ballistic missile threats.
How does GMD fit into the Ballistic Missile Defense System (BMDS)?
GMD provides combatant commanders with the capability to defend our homeland against a limited long-range ballistic missile attack outside of earth’s atmosphere in the midcourse phase of the hostile missile’s flight.
What is a Ground-Based Interceptor (GBI)?
A GBI is a three-stage, solid fuel booster with an Exoatmospheric Kill Vehicle (EKV). When launched, the booster missile carries the EKV toward the target’s predicted location in space;the EKV then rams the warhead using only the force of a direct collision to destroy the target.
What is an Exoatmospheric Kill Vehicle (EKV)?
The Exoatmospheric Kill Vehicle (EKV) is a 155-pound sensor/propulsion package that uses the kinetic energy from a direct hit to destroy the incoming target vehicle. Once released from the booster, the EKV uses guidance transmitted to it and from its own on-board sensors to close with and destroy the target warhead well outside Earth’s atmosphere.
Is there an explosion when the Exoatmospheric Kill Vehicle hits the reentry vehicle?
No. There is a collision in space. It is very powerful and generates debris, gas and dust. The gas and dust may actually look like they burn, but only for an extremely short time. The debris and dust will reenter the atmosphere and burn up like meteors.
What type of debris results from a missile intercept?
For the Ground-Based Interceptor, the intercept is the result of a direct collision between the interceptor's Exo-atmospheric Kill Vehicle (EKV) and the target warhead in the exo-atmosphere (outside Earth's atmosphere). Because the target warhead is literally pulverized by the direct collision, debris from the target warhead and the interceptor is minimal. Orbital debris is essentially non-existent since both the EKV and target are in downward trajectories at intercept, where the debris is burned up during reentry into the atmosphere.
What are Ground Support & Fire Control Systems?
Ground Support & Fire Control Systems consist of redundant fire control nodes, interceptor launch facilities, and a communications network. GMD Fire Control (GFC) receives data from satellites and ground based radar sources, then uses that data to task and support the intercept of target warheads using Ground-Based Interceptors. The GFC also provides the Command & Control, Battle Management & Communications element with data for situational awareness.
What GMD assets are in place?
Ground-Based Interceptors are emplaced at Fort Greely, Alaska and Vandenberg Air Force Base, Calif. A total of 30 interceptors have been emplaced. On March 15, 2013, the Department of Defense announced that 14 additional interceptors will be emplaced at Fort Greely, Alaska by 2017.
Fire control, battle management, planning, tasking and threat analysis take place via a dual-node, human-in-control interface in Fort Greely, Alaska and Colorado Springs, Colo. Warfighters of the 49th Missile Defense Battalion at Fort Greely, Alaska and of the 100th Missile Defense Brigade at Colorado Springs, Colo., operate the system.
Has the Department of Defense decided to build an additional interceptor site in the Continental United States (CONUS)?
No decision has been made to construct an additional missile defense site in the United States.
Per Congressional direction, we are preparing an Environmental Impact Statement for military bases in Ohio, Michigan, New York and Maine which will take about two years to complete.
How do I learn more about the other elements of the Ballistic Missile Defense System (BMDS)?
All of the elements of the BMDS are described in our System section.

How is the PAC-3 missile different from the PATRIOT used in Desert Storm?
The PAC-3 missile is a mobile, high-velocity, hit-to-kill interceptor developed to provide increased defense capability against short-range ballistic missiles, cruise missiles, and aircraft. Unlike earlier versions of the PATRIOT missile, which use an explosive warhead to destroy their targets, the PAC-3 missile collides with its target in mid-air at extremely high speed, destroying the target and neutralizing its payload. Other system upgrades include: improved radar performance allowing enhanced target discrimination and new system software that improves determination of target launch and impact points and provides an interface with THAAD. PAC-3 is currently deployed with the U.S. Army around the world.
Is PAC-3 being developed by the MDA?
No, the U.S. Army is responsible for production and further development of the PAC-3; the Missile Defense Agency remains responsible for the Ballistic Missile Defense System and PAC-3 interoperability and integration efforts.
formerly called the Joint National Integration Center (JNIC)
What makes the MDIOC unique at the MDA?
