Missile Defense Agency

Anti-ballistic missile launcher The MDA currently publishes the following mission statement: The National Defense Authorization Act is cited as the original source of the MDA's mission: ==International mission==

is an exoatmospheric hypersonic anti-ballistic missile, jointly funded, developed and produced by Israel and the United States.|alt= Ballistic Missile Defense Systems (BMDS) must be capable of operating in different regions of the world to ensure the success of the MDA mission. The International Strategy was approved by the MDA Director in 2007. The general strategy for international efforts is: :Outreach: Communicate the importance of missile defense by promoting worldwide BMDS by sharing information with allies and partners. :Capability and Interoperability: Identify and integrate U.S and partner systems to create global missile defense system. Promote interoperability among allies. :Technology: Identify and evaluate possible international technology in support of BMDS capabilities. :Investment: Identify and execute investment opportunities with allies and partners. :Workforce: Shape a qualified workforce to execute the MDA International Strategy. As of 2017 MDA was working on facilities in Germany, Romania, Poland, Japan, Qatar, Saudi Arabia and the United Arab Emirates. ==Potential threats against the United States==

Ballistic missile systems using advanced liquid- or solid-propellant propulsion are becoming more mobile, accurate and capable of striking targets over longer distances and are proliferating worldwide. • Iran currently has short- and medium- range missiles with guidance systems. Iran's launch of a medium range, solid fuel ballistic missile demonstrates its ability to hit targets in Israel and southern Europe. Iran also successfully launched the Safir Space Launch Vehicle on Feb 2, 2009. It was then speculated that development of an ICBM was not far behind. Intelligence reports that a missile could have been built sometime between 2010 and 2015 perhaps using help from Russian and North Korean technology. Iran also recently developed a hypersonic ballistic missile in 2022, which can move fifteen times the speed of sound and can reach U.S. and European targets, as well as the U.S. mainland, in 15 minutes. • North Korea currently deploys a Nodong ballistic missile capable of hitting Japan and South Korea, and is developing a new intermediate-range ballistic missile (IRBM) which could reach Guam and the Aleutian Islands. They also successfully demonstrated the staging and separation technologies required to launch a Taepo-Dong 2 ICBM, which has the capability to reach the United States. The Taepodong missile was first tested in 2006, and failed 40 seconds into midflight. North Korean missiles are notoriously unreliable, and many of the DPRK's missile tests have failed, including the most recent Taepodong-2 launches in 2009 and 2012, and a failed launch of the BM25 Musudan in 2016. On 1 January 2017, North Korea announced its final preparation for a test of an ICBM, for the first time. On 6 March 2017, North Korea launched four missiles from Tongchang-ri, a known long-range missile site at 7:36 a.m. local time, one of which landed in the Sea of Japan, with the remaining three missiles landing in Japan's economic zone. On July 4, 2017 North Korea launched a ballistic missile that had the potential to be an ICBM. It flew through space and landed in the Sea of Japan. "The launch continues to demonstrate that North Korea poses a threat to the United States and our allies," a Pentagon statement said. • Syria has been identified as a host for short-range ballistic missiles (as it acquires equipment from North Korea and Iran). ==Categories==

surface-to-air missile (SAM) with anti-ballistic missile capabilities. MDA divides its systems into four phases: boost; ascent; mid-course; and terminal. Each of these corresponds to a different phase of the threat ballistic missile flight regime. Each phase offers different advantages and disadvantages to a missile defense system (see missile defense classified by trajectory phase), and the geography of each defended area dictates the types of systems which can be employed. The resultant flexible and layered defense approach concept is believed to improve overall defense effectiveness. The more opportunities a system has to neutralize a threat (e.g., by shooting down a missile), the better the chance of success. Activities have also been categorized as fulfilling the goals of one of five "blocks". For example, "block 4.0" was stated as "Defend Allies and Deployed Forces in Europe from Limited Iranian Long-Range Threats and Expand Protection of U.S. Homeland". It included the US missile defense complex in Poland to be constructed, and the European Mid-course Radar (EMR), currently located at the Ronald Reagan Ballistic Missile Defense Test Site at Kwajalein Atoll, which was to have been modified and relocated to the Czech Republic. On 17 September 2009, the Obama administration scrapped the "block 4.0" plan, in favor of a new so-called "European Phased Adaptive Approach" (EPAA). Boost phase Can intercept all ranges of missiles, but the missile boost phase is only from one to five minutes. It is the best time to track the missile because it is bright and hot. The missile defense interceptors and sensors must be in close proximity to the launch, which is not always possible. This is the most desirable interception phase because it destroys the missile early in flight at its most vulnerable point and the debris will typically fall on the launching nations' territory. Ascent phase This is the phase after powered flight but before the apogee. It is significantly less challenging than boost phase intercepts, less costly, minimizes the potential impact of debris, and reduces the number of interceptors required to defeat a raid of missiles. Midcourse phase This phase begins after the booster burns out and begins coasting in space. This can last as long as 20 minutes. Any debris remaining will burn up as it enters the atmosphere. Ground-based missile defense systems can defend from long-range and intermediate-range ballistic missiles in this phase. Mobile elements can defend against medium and short ranged missiles in midcourse. Terminal phase This phase is the last chance to intercept the warhead. This contains the least-desirable Interception Point (IP) because there is little room for error and the interception will probably occur close to the defended target. == Defenses ==

Boost phase defense Research and development: • Kinetic Energy Interceptor (KEI) – In December 2003, MDA awarded a contract to Northrop Grumman for developing and testing. It will have to be launched from a location not too far from the launch site of the target missile (and is therefore less suitable against large countries), it has to be fired very soon after launch of the target, and it has to be very fast itself (6 km/s). In 2009, the Department of Defense and MDA determined the technological issues were excessive and cancelled the program, allocating no funding for it in its later budget submission. • Boeing YAL-1 Airborne Laser (ABL) – Team ABL proposed and won the contract for this system in 1996. A high-energy laser mounted on a converted 747 airliner was used to intercept a test target in January 2010, and the following month, successfully destroyed two test missiles. While the program has been cancelled due to concerns about its practicality with present technology (while successful the system was still extremely short ranged, likely needing to fly in heavily defended space to make an interception) the YAL-1 served to demonstrate the potential of such a system. The capabilities of being deployed rapidly to any part of the world and of intercepting a large number of missiles would make a future system extremely attractive. However, the entire concept was deemed infeasible and cancelled without successors in December 2011. • Network Centric Airborne Defense Element (NCADE) – On September 18, 2008 Raytheon announced it had been awarded a $10 million contract to continue research and development of NCADE, a missile defense system based on the AIM-120 AMRAAM. • Golden Dome, multi-layer missile defense system for the United States, intended to detect and destroy ballistic, hypersonic, and cruise missiles before they launch or during flight. One can distinguish disabling the warheads and just disabling the boosting capability. The latter has the risk of "shortfall": damage in countries between the launch site and the target location. See also APS report. Ascent phase defense Research and development: • Ascent-Phase intercept System (API) – Emerging intercept technologies are being developed and designed to defeat launched missiles in their ascent phase. This phase is after the boost phase and prior to the threat missile's apogee (midcourse). The Ascent phase intercept program is still classified so there is little information on it. • Golden Dome Midcourse (ballistic) phase defense In use: • Ground-Based Midcourse Defense (GMD) • Aegis Ballistic Missile Defense System (Aegis BMD) Research and development: • Multiple Kill Vehicle (MKV, originally Miniature Kill Vehicle): the Department of Defense has canceled the MKV program in 2009, however a similar program restarted in August 2015, when Raytheon, Boeing, and Lockheed Martin were contracted to design a Multi-Object Kill Vehicle concept. Hypersonic glide phase defense Research and development: ::This section included material from United States Army Futures Command By 2021, the Missile Defense Agency (MDA) realized that it almost had a countermeasure to hypersonic boost-glide weapons, by using existing data on the adversary hypersonic systems which were gathered from existing US satellite and ground-based sensors. MDA then fed this data into its existing systems models, and concluded that the adversary hypersonic weapon's glide phase offered the best chance for MDA to intercept it. These GPI interceptors could first be offered to the Navy for Aegis to intercept using the C2BMC, and later to the Army for THAAD to intercept using IBCS. By 2024, a first test of the hypersonic tracking sensors was imminent. • Glide Phase Interceptor, in Sep 2024, Northrup Grumman was selected to continue development on the Glide Phase Interceptor, a new missile defense asset designed to take down hypersonic weapons during the glide phase of the flight. • Golden Dome Terminal phase defense In use: • Terminal High Altitude Area Defense (THAAD) • PATRIOT Advanced Capability-3 (PAC-3) • Arrow missile, a joint effort between the U.S. and Israel Research and development: • Medium Extended Air Defense System (MEADS), co-developmental program of the United States Department of Defense, Germany and Italy. • Golden Dome ==List of directors==
