The administration’s budget request for FY 2019 prioritizes near-term readiness against limited but growing ballistic missile threats from sources such as North Korea. This choice, however, falls short of connecting missile defense efforts to the reality of renewed great power competition as articulated in the National Defense Strategy.
Recent budget moves will give the U.S. missile defense effort a major boost in funding over the coming year, likely allowing the purchase of additional Ground Based Interceptor missiles on top of the 44 already deployed for use by the Ground-based Midcourse Defense system against ICBMs headed toward the U.S. homeland.
Iran’s missile forces, in tandem with other strategic tools, support a complex national security strategy that both enables the projection of power across the region, and imposes costs on adversaries seeking to directly challenge Iran’s regime.
In a nuclear world, nuclear weapons are needed to deter major attacks, but who should possess these instruments of deterrence? Today the challenge of keeping nonnuclear states from going nuclear may be growing, perhaps nowhere quite as much as in northeast Asia…
Despite the rising salience of missile threats, current air and missile defense forces are far too susceptible to suppression. Today’s U.S. air and missile defense (AMD) force lacks the depth, capacity, and operational flexibility to simultaneously perform both missions
Missile defense funds are likely to grow—a lot. In addition to a September reprogramming of an additional $249 million for the Missile Defense Agency for FY 2017, appropriations for FY 2018 could exceed $11 billion, over $3 billion more than the president’s original request. This would make for the highest level of missile defense funding in a decade…
The U.S. Army has been at war continuously for 16 years. New technologies pose new threats and old technologies grow in numbers and capability. If ever the Army were ever to think creatively about how to meet the extraordinary demands it faces, now would be the time.
President Trump’s recent claim that U.S. ballistic-missile defenses are effective “97 percent of the time” has provoked much discussion about the capabilities of one U.S. defense system in particular: Ground-Based Midcourse Defense.
In the 1990s, the U.S. intelligence community assessed that North Korea might acquire an intercontinental ballistic missile by 2015. That threat is now here.
In early August 2017, North Korea announced plans to launch four intermediate-range ballistic missiles towards the waters surrounding Guam — perhaps 30 or 40 kilometers from the island’s coast.
As missile defense capabilities have matured, they have become widely recognized for their contribution to broad strategic objectives and the US nuclear posture. The growing significance of missile defenses has been more broadly reflected in major national and military strategy documents across the last several administrations.
A new challenge faces the joint force: the prospect of conflict with a near-peer adversary who has spent two decades going to school on the U.S. way of war. Potential adversaries have integrated air defenses and precision-strike weapons that can hold forward-based U.S. forces at risk, complicate maneuver and impair freedom of action.
Despite Iran’s apparent compliance with the nuclear deal concluded in 2015, its missile programs remain a serious concern. Since 2006, the United Nations has repeatedly sanctioned Iran’s ballistic missile programs,…

North Korea conducted a flight test of an intercontinental ballistic missile (ICBM) that it has designated the Hwasong-14. During the July 3 test, the Hwasong-14 traveled for around 40 minutes before landing in the Sea of Japan, inside Japan’s exclusive economic zone…
The Missile Defense Agency yesterday conducted an intercept test of the Standard Missile-3 Block IIA (SM-3 IIA), a relatively new interceptor designed for use in the Aegis Ballistic Missile Defense (BMD) program. Something appears to have gone wrong, however, and the interceptor did not destroy its target. The type or cause of failure is not yet known, nor will it likely be known for some time.
Missile threats facing both the United States and its allies in the Asia-Pacific are increasing in complexity, number, and source. In response, the Trump administration is using missile defenses to boost military capability and signal resolve, as indicated by the deployment of THAAD to South Korea…
This is a good day for homeland missile defense, and a bad day for Kim Jong-un.

Nations around the world continue to develop a growing range of ballistic and cruise missiles to asymmetrically threaten U.S. forces, allies, and the American homeland. Missile defenses have now become an essential part of U.S. defense policy and strategy, and their importance shows no sign of diminishing.
U.S. nuclear deterrent forces have long been the foundation of U.S. national security and the highest priority of the Department of Defense. As President-elect Donald Trump has observed, nuclear weapons…

Missile defense is not just about ballistic missiles. The wider problem of integrated air and missile defense, to include cruise missiles, has received growing attention in recent years. However, attempts to design and field an architecture to detect and track cruise missiles has proven challenging…
The Unha launch is hardly the basis for panic, but it is time for certain measures to ensure security and stability. Coming on the heels of the North’s fourth nuclear detonation, the launch reflects both continued technical advances and their sustained ICBM ambitions. These recent events mean that active measures to counter North Korea’s missile program will likely take on renewed importance.
On the morning of February 7, North Korea launched an Unha-type rocket, headed due south. The rocket then apparently orbited an “earth observation satellite” called Kwangmyongsong-4 (lode star), reportedly weighing 200 kilograms, about twice the size of a satellite by the same name orbited in December 2012…
North Korea’s fourth nuclear test has provoked renewed calls among leading South Korean lawmakers for South Korea to obtain its own nuclear deterrent force. Public opinion has also become more supportive of a nuclear-armed South Korea.
