Missile Defense Tester Calls for Redesign

The Pentagon’s chief weapons tester has called for the redesign of a key component of the U.S. long-range missile interceptor system, raising questions about plans to expand it.

Tom Z. Collina

The Defense Department’s chief weapons tester called in January for the redesign of a key component of the U.S. system intended to intercept long-range missiles launched from North Korea or Iran, raising questions about the department’s plans to expand the current system.

J. Michael Gilmore, the Pentagon’s director of operational test and evaluation, wrote in his annual report, released Jan. 29, that recent test failures of the U.S. ground-based interceptor (GBI) system raise concerns about the system’s reliability and suggested that the missile’s exoatmospheric kill vehicle (EKV) be redesigned to assure it is “robust against failure.”

Echoing Gilmore’s view, Frank Kendall, undersecretary of defense for acquisition, technology and logistics, told a Feb. 25 conference in Washington, “We’ve got to get to more reliable [missile defense] systems.” Merely “patching the things we’ve got is probably not going to be adequate. So we’re going to have to go beyond that,” he said.

The EKV plays a central role in the missile defense mission. It is lifted into space by a booster rocket and then uses its onboard sensors to locate an incoming enemy warhead and destroy it on impact. U.S. officials have compared the task to hitting a bullet with another bullet.

The currently deployed EKVs, built by Raytheon, have missed in their last three tests. One model, called the CE-II, failed its only two tests, both in 2010. An older model, the CE-I, failed last summer. Nonetheless, these same EKVs are now operationally deployed on 30 GBI missiles in Alaska and California, and the Pentagon announced last March that it would add 14 more missiles armed with the CE-II by 2017, if the next test, planned for this summer, is successful. (See ACT, April 2013.)

Deployment Decision

Based on Gilmore’s report, some are now calling on the Pentagon to delay expansion of the system until the new technology is ready. “Not another dime should be spent on more bad GBIs at Fort Greely [in Alaska] or anywhere else. Instead, a new GBI/EKV must be designed, built, and successfully tested to replace the old design,” former Pentagon testing director Philip Coyle said in a Feb. 11 e-mail to Arms Control Today.

Although redesigning the system would likely take five years or more and delay the Pentagon’s plan to field more GBI missiles by 2017, missile defense supporters are reportedly worried that lawmakers might resist paying $1 billion to field interceptors with the troubled EKV on board.

Richard Lehner, a spokesman for the Pentagon’s Missile Defense Agency (MDA) said in a Feb. 11 e-mail to Arms Control Today that “the 14 additional interceptors will have the second-generation [CE-II] kill vehicle. At this point in time I know of no changes to this plan.”

According to congressional staffers, it is no secret that the GBI EKV needs to be redesigned and that the MDA and Congress support that goal. They said that Congress fully funded the administration’s $70 million request for the Common Kill Vehicle program in the omnibus appropriations bill for fiscal year 2014. The aim of that program is to build a common EKV for the missiles in the GBI system and the more successful Standard Missile-3 (SM-3), built by Lockheed Martin and now deployed on Navy ships equipped with the Aegis missile defense radar system. According to the MDA, the Common Kill Vehicle program is a continuation of the effort to develop an EKV for the SM-3 IIB, which was canceled last March and was meant to have some capability against long-range missiles.

In November, Boeing, Lockheed Martin, and Raytheon each received a contract from the MDA to develop designs for a common EKV. Development of a new EKV will cost $560 million over the next five years, part of a $4.5 billion increase that is expected for missile defense funding over that period, Reuters reported Feb. 7.

The congressional staffers said that there is bipartisan agreement that the Alaska expansion should go forward with the CE-II if the next test is successful. As one staffer said, “You can only field what you have in hand” even if there are plans to make it better in the future.

Eastern Sites Announced

Meanwhile, the Defense Department announced Jan. 31 that it would conduct environmental impact studies for four possible missile defense sites in the eastern United States, as directed by Congress, but that no decision has been made to construct a new site.

The four sites are Fort Drum in New York, SERE Training Area at Naval Air Station Portsmouth in Maine, Camp Ravenna Joint Training Center in Ohio, and Fort Custer Training Center in Michigan. A site in Vermont was dropped from the original list released in September. (See ACT, October 2013.) The Pentagon said it would take about 24 months to complete the review process.

Russia Links Missile Defense, Iran Deal

Russian Foreign Minister Sergey Lavrov said an agreement on Tehran’s nuclear program would remove the justification for NATO missile defenses.

Tom Z. Collina

The recent deal between six world powers and Iran to temporarily freeze Tehran’s nuclear program would eventually remove the main rationale for NATO’s missile defense plans, Russian Foreign Minister Sergey Lavrov said in December.

“Implementation of the Geneva agreement on Iran will remove the cause for construction of a missile shield in Europe,” Lavrov told a Dec. 19 news conference in Poland, where U.S. missile interceptors are planned to be installed by 2018. Lavrov was referring to an interim agreement reached in Geneva on Nov. 24 by Iran and six global powers (China, France, Germany, Russia, the United Kingdom, and the United States) that are seeking to ensure Tehran does not develop nuclear weapons. The agreement adds a new twist to long-standing Russian arguments against U.S. and NATO plans to field missile defenses in central Europe.

In his comments, Lavrov was highlighting the U.S. contention that a Europe-based missile defense system was needed to counter the potential threat to Europe of a missile attack from Iran. U.S. President Barack Obama said in Prague in 2009, “If the Iranian threat is eliminated, we will have a stronger basis for security, and the driving force for missile defense construction in Europe will be removed.”

But current and former U.S. officials say that it would be premature to assume the Iran deal will succeed and that even if it does, that alone would not remove the threat from Iran. According to a Dec. 16 press statement by Defense Department spokesman Carl Woog, Defense Secretary Chuck Hagel told his Russian counterpart, Sergey Shoygu, during a video teleconference earlier that day that the Iran deal does not obviate the need for the United States and its NATO allies to continue their current approach to missile defense in Europe. Hagel told Shoygu said that U.S. and NATO missile defense efforts do not threaten Russia, and he urged Moscow to continue consultations with Washington on missile defense cooperation, Woog said in the statement.

Ivo Daalder, U.S. ambassador to NATO from 2009 to 2013, said in a Dec. 18 interview that the interim agreement starts a promising process but that “the outcome is not inevitable.” Even if the threat of an Iranian nuclear weapon were removed, there would still be the threat from Tehran’s missiles, he said, which can reach southern Europe. But if both threats were eliminated, “I would not be surprised to see a new debate on this in NATO,” Daalder said.

In a separate Dec. 18 interview, a senior Republican Senate staffer said that, in the context of U.S. missile defense, Iran will maintain a capability to break out from any future nuclear agreement “faster than we can deploy missile defenses.” He said that existing U.S. plans to field up to 44 interceptors in Alaska and California are “enough for the current Iran situation,” but that if Tehran flight-tests a long-range missile, which it has not done, “that would be an indicator” to start new projects, such as a missile interceptor site on the U.S. East Coast.

Meanwhile, Russian President Vladimir Putin said Dec. 19 that Moscow was considering the deployment of Iskander short-range missiles, which could carry nuclear warheads, in Kaliningrad, a Russian territory on the Baltic Sea within striking distance of where U.S. missile defenses would be deployed in Poland.

“One of the possible responses [to Western missile defense plans] is to deploy Iskander complexes in Kaliningrad...but I want to draw your attention to the fact that we have not yet made this decision,” Putin said at a press conference, according to RT News.

Putin was contradicting press reports that the Iskanders already were in Kaliningrad, based on a Dec. 16 Russian Defense Ministry statement that “Iskander rocket complexes are indeed standing armed with the rocket and artillery divisions in the Western Military District,” which includes Kaliningrad.

Russia warned two years ago that it would put Iskanders in Kaliningrad if NATO were unable to convince Moscow that its missile defense plans were not a threat to Russia. Dmitry Medvedev, then president and now prime minister, said in November 2011 that the missiles could be placed in the region to “secure the destruction of the European component of the U.S. missile defense system.” (See ACT, January/February 2012.) It is not clear whether the missiles are armed with nuclear or conventional warheads.

Russia has been seeking a legal guarantee that NATO missile interceptors would not be used against Moscow’s nuclear-armed, long-range ballistic missiles. NATO has refused, offering political assurances instead.

The Iskander-M, the version of the missile that may be deployed to Kaliningrad, has a range of up to 400 kilometers and is not banned by any U.S.-Russian treaty. It could potentially target ground-based radars and interceptors deployed at Redzikowo, Poland, a site 250 kilometers from Kaliningrad at which NATO plans to deploy interceptor systems by 2018.

Interceptors are also planned for Romania by 2015. Ship-based interceptors were deployed in the Mediterranean Sea in 2011, along with a radar in Turkey. Last March, the Pentagon canceled U.S. plans to field more-capable interceptors in Poland by 2020.

U.S. Secretary of State John Kerry said Nov. 5 in Warsaw that the plan to field the system in Poland by 2018 is “absolutely on target” and noted that officials had recently broken ground on the site in Romania.

In the interview, Daalder said that the possible Russian action is less about missile defense and “all about Poland” because “Russia does not want NATO military capability” in the former Warsaw Pact country. Moscow is sending the message that “the threat to Poland will go up” if interceptors are fielded as planned, he said.

Moscow appears to be much more concerned about U.S. plans for missile defense in Europe than actual interceptor deployments in the United States, which have a greater capability against Russian long-range missiles, Daalder said.

Hill to Fix, Not Expand, Missile Defense

The final version of the defense authorization bill dropped House language calling for an East Coast missile defense site and boosted funding to improve interception technology.

Tom Z. Collina

Congress voted in December to drop a controversial proposal to build a new missile defense interceptor site on the U.S. East Coast, agreeing instead to spend more to fix problems with the existing system, which has failed in its last three intercept tests.

The new policy is included in the final $625 billion National Defense Authorization Act, signed by President Barack Obama on Dec. 26. The legislation authorizes raising federal spending on missile defense by $358 million to $9.5 billion for the fiscal year that began last Oct. 1 and runs through Sept. 30.

The final bill dropped a measure approved by the Republican-controlled House of Representatives, which called for spending $140 million on a new missile interceptor site on the East Coast. Instead, the final legislation authorizes $190 million to upgrade the existing Ground-Based Midcourse Defense (GMD) system to counter long-range ballistic missiles. The GMD system is currently operational at one site each in Alaska and California. That system, first deployed in 2004, had its last successful intercept test in 2008, failing twice in 2010 and again last July.

In interviews Dec. 16-17, senior congressional staffers from both parties described the new approach as a bipartisan agreement to upgrade the current system rather than build a new site. Given the problems with the GMD system, Congress has decided to “fix what we’ve got,” said one senior Republican staffer. He said that the administration’s initial budget request to Congress did not include enough money to fix the system’s inadequacies.

The House approved its version of the defense bill June 14 with a requirement that the Defense Department establish an East Coast missile interceptor site by 2018. The Senate version, passed by the Armed Services Committee on June 13, contained no such provision. The bill did not receive a vote by the full Senate.

Vice Adm. James Syring, director of the Defense Department’s Missile Defense Agency (MDA), wrote to the Senate on June 10 that there was no military requirement for an East Coast site. Syring said he would rather invest funds in new sensors that could help the existing system distinguish real targets from fake ones. (See ACT, July/August 2013.)

The system’s ability to tell the difference between real and fake targets is critical because an attacker’s warheads would likely come surrounded by debris and decoys. In congressional testimony last May, Michael Gilmore, the Defense Department’s director of operational testing, said, “If we can’t discriminate what the real threatening objects are, it doesn’t matter how many ground-based interceptors we have; we won’t be able to hit what needs to be hit.”

Noting that Senate Republicans did not have the votes to mandate an East Coast site, the Republican staffer said that a new site should not be established until the system’s performance can be improved through upgrades to sensors and kill vehicles, the devices that sit on top of interceptor missiles and are supposed to collide with an enemy warhead in space. It is not clear that such upgrades would be achievable by 2018, according to the staffers.

To address Syring’s call for better sensors, the defense act authorizes $30 million as a down payment on the deployment of an additional “long-range discriminating radar” to track missiles launched from North Korea. The new radar would likely be located in Alaska, according to the congressional staffers. The act also says that the secretary of defense should be prepared to field additional sensors near the East Coast by 2019 if a future long-range missile threat emerges from Iran. Unlike North Korea, Tehran has not tested a long-range missile that could reach the United States, although it reportedly sent a monkey into space Dec. 14.

New Radar, Kill Vehicle

In addition to $30 million for the radar, the defense act authorizes $80 million to fix problems that caused the most recent GMD test failure last July, $50 million for better capabilities to distinguish real warheads from fake ones, and $30 million to develop a better kill vehicle. The act allocates $20 million for studying a possible new interceptor site on the East Coast.

Reflecting the MDA’s desire for a more reliable and capable kill vehicle, the act requires the agency to prepare a plan this May to “develop, test, and deploy” an upgraded kill vehicle to be fielded in 2018 or later that can pick out “lethal objects.” This effort is expected to eventually cost up to $150 million per year, according to the Republican staffer.

The Pentagon announced last March that it intends to increase the number of U.S. interceptors from 30 to 44 by 2017, with the additional 14 to be placed at Fort Greely in Alaska. Before that can happen, the interceptor must be successfully tested, according to the Defense Department. The next intercept test is planned for this spring. (See ACT, September 2013.) These additional 14 interceptors have already been purchased, so they would not include the proposed upgrades, the staffers said.

House Provisions Diluted

Like the requirement for an East Coast missile defense site, other aspects of the original House bill were watered down in the final version of the legislation. For example, the House bill would have blocked reductions required by the 2010 New Strategic Arms Reduction Treaty (New START) until the Pentagon submitted an implementation plan, and it said that reductions below the levels specified in New START could be carried out only under a formal treaty approved by Congress. Obama called for such reductions in a speech last June.

In contrast, the compromise bill allows the Pentagon to prepare for New START reductions, which do not have to be completed until 2018. In addition, the bill expresses only the nonbinding “sense of Congress” that further arms reductions “should” be “pursued through a mutually negotiated agreement” with Russia under the president’s “treaty-making power.”

The defense bill language authorizes about $30 billion more than Congress will be allowed to appropriate under the terms of a bipartisan budget agreement approved in December. Appropriators must decide which programs to cut back by Jan. 15, when the current budget agreement expires.

Missile Defense Against Iran Without Threatening Russia

Cancellation of the planned fourth phase of the European Phased Adaptive Approach has removed any capability that the fully deployed system would have had to intercept Russian intercontinental ballistic missiles but does not diminish the system’s capability against Iranian missiles.

Jaganath Sankaran

All recent U.S. efforts after the conclusion of the 2010 New Strategic Arms Reduction Treaty (New START) to move ahead on bilateral nuclear arms reductions with Russia have stalled over Russian concerns regarding the capabilities of the European Phased Adaptive Approach, as the Obama administration’s missile defense policy in Europe is formally known, and its effect on Russian nuclear retaliatory potential.

Since the early stages of the phased adaptive approach, Russian officials have cited it as an obstacle to further nuclear arms reduction. Last March, however, U.S. Secretary of Defense Chuck Hagel announced a restructuring of the approach, canceling the planned implementation of its fourth phase, which had prompted the strongest Russian complaints.[1] The key feature of that phase was the deployment of the Standard Missile-3 (SM-3) IIB interceptors in Poland. The SM-3 IIB, with a planned velocity of 5.5 kilometers per second, would have had the ability to fly further and faster than any other missile in the system.

Cancellation of the fourth phase has removed any capability that the fully deployed system would have had to intercept Russian intercontinental ballistic missiles (ICBMs). As described below, Russia should be able to independently verify that, under the restructured plans, the system will not be able to intercept Russian ICBMs even when fully deployed. At the same time, proponents of the phased adaptive approach can be confident that the cancellation of the planned deployment of the SM-3 IIB interceptors did not diminish the ability of the system to intercept Iranian missiles. This restructuring should now pave the way for more-productive U.S.-Russian negotiations on nuclear arms reduction.

The U.S.-Russian Discourse

The phased adaptive approach was originally viewed by many as an attempt to ease Russian concerns over the previous administration’s missile defense plans in Europe. In 2007 the Bush administration proposed deploying a ground-based midcourse defense system in Europe to defend against Iranian missile threats. That system would have included 10 interceptors in Poland, a radar in the Czech Republic, and another transportable radar deployed in a country close to Iran. This proposal raised strong opposition from Russia.[2]

On September 17, 2009, the Obama administration announced it would cancel the Bush-proposed European missile defense program. Instead, the plan was to develop and deploy a missile defense capability based on SM-3 interceptors on land and on ships equipped with the Aegis missile defense system. The interceptors to be deployed in a phased manner, adapting to the threat posed by Iran. Moscow initially welcomed this decision with caution.[3] As details on the phased adaptive approach emerged, however, Russia argued that this missile defense system still posed threats to Russian ICBMs. Russian political leaders have claimed that the phased adaptive approach, particularly the now-canceled fourth stage of the system involving advanced high-velocity interceptors and possibly advanced missile-tracking satellites, was a threat to its strategic nuclear deterrent and a potentially destabilizing element.[4]

Russia has asked for legally binding “military-technical” guarantees from the United States and NATO that the missile defenses that they are deploying in Europe will not be aimed against Moscow’s strategic nuclear forces.[5] The only publicly available explanation of what constitutes military-technical guarantees describes them as making certain changes to the algorithms of the operation of missile defense radars, refraining from bringing Aegis-equipped ships into areas that are in direct proximity to the potential trajectories of Russian ICBMs and submarine-launched ballistic missiles, stationing Russian observers at U.S. and NATO missile defense installations, and formulating a mechanism to monitor the implementation of such measures.[6]

Russian President Vladimir Putin has stated that his government would contemplate further bilateral nuclear arms reductions only if the United States addressed concerns about the evolving ballistic missile system. “Russia is open to new joint initiatives” in arms control, Putin said in an August 2012 statement. “At the same time, their realization is clearly possible only on a fair mutual basis and if all factors affecting international security and strategic stability are taken into account.” Among the factors, according to Putin, is the “unilateral and totally unlimited deployment of a global U.S. missile defense system.”[7]

Dmitry Medvedev, Russia’s president from 2008 to 2012, had expressed similar views. Speaking at the 2011 summit of the Group of Eight industrialized countries, Medvedev said, “If we do not reach an agreement by 2020, a new arms race will begin.”[8] He further suggested that “a European missile defense system can only be genuinely effective and viable if Russia participates in an equal way.”

Initially, the Kremlin had demanded that Europe be divided into two sectors, with NATO taking responsibility for providing missile defenses for one and Russia for the other. Under this arrangement, the two sides would have equal authority in decision-making for interceptor launches.[9]

The United States and other NATO countries did not agree to Russia’s proposals for such sectoral missile defense. Citing Article 5 of the North Atlantic Treaty, which says that an attack on any member “shall be considered an attack against them all” and that each member “will assist” the attacked country, they claimed that NATO alone bears responsibility for defending the alliance from ballistic missile threats.[10]

The constant U.S. response to Russian claims of vulnerability has been that the interceptors to be deployed under the phased adaptive approach would not pose a threat to Russian missile forces. Responding to such concerns in late 2011, Rose Gottemoeller, acting undersecretary of state for arms control and international security, said, “We have worked at the highest level of the United States government to be transparent about our missile defense plans and capabilities and to explain that our planned missile defense programs do not threaten Russia or its security.”[11]

The United States has declined to engage in negotiations on any formal agreement with Russia on the phased adaptive approach. In March 2012, Ellen Tauscher, U.S. special envoy for strategic stability and missile defense, said Russia was seeking a “legal guarantee” with a set of military-technical criteria that would limit the ability of the United States to deploy future missile defense systems. Tauscher said Russia also was asking for data on when U.S. Aegis-equipped ships entered certain waters and when an interceptor achieved a certain velocity. The United States “will not accept limitations on the capabilities and numbers of our missile defense system” or on where it deploys the Aegis-equipped ships, she said. Those vessels are “multi-mission ships that are used for a variety of missions around the world, not just for missile defense,” she said.[12]

Nevertheless, the U.S. government has expressed a willingness to accept a political agreement affirming that U.S. missile defenses are not aimed at Russia. Tauscher explained that any such statement would be politically but not legally binding and would publicly proclaim Washington’s intent to work with Moscow in charting a course for cooperation on missile defense.[13]

Russia has continued to insist on a legally binding agreement with limits on U.S. missile defense operations. Such a legally binding agreement seems very difficult to achieve given the strong Republican animosity to it in Congress. The Senate resolution supporting ratification of New START, for example, specifically stated that the Senate would not accept any limitations on missile defense.

System Capabilities

Russian concerns, as well as the U.S. responses to those concerns, are closely tied to the location and capabilities of the various elements of the phased adaptive approach. Under that approach, interceptors would be stationed in phases on Aegis-equipped ships in the Mediterranean Sea and at land sites at Deveselu, Romania, and Redzikowo, Poland, to defend against a variety of current and future Iranian missile threats. The first phase of the approach is already in place with a command center in Germany, a forward-based radar in Turkey, and an Aegis-equipped ship with SM-3 IA interceptors deployed in the Mediterranean Sea. Phase II, consisting of SM-3 IB interceptors deployed in Romania, and Phase III, consisting of SM-3 IIA interceptors deployed in Poland, are to begin in 2015 and 2018, respectively (fig. 1). The previously planned fourth phase, consisting of the SM-3 IIB interceptors, was to be deployed in Poland.[14]

The major Russian concern with the system has been with the capability of the SM-3 IIB interceptors that were to be deployed as part of the fourth phase at the Polish site around 2022. The Russians have suggested that the interceptors would be able to intercept Russian ICBMs. Yet, modeling done by this author using minimum energy trajectories of the missiles and interceptors shows that interceptors at that site do not pose a viable threat to Russian ICBMs.[15] Under the original conception of the phased adaptive approach, an SM-3 IIB interceptor launched even with an idealized “zero time delay”—that is, immediately after the launch of the target ICBM—would be able to intercept Russian ICBMs from only five missile sites in western Russia. Modeling demonstrates that, even under these conditions, Russia would be able to launch its ICBMs from at least nine other launch sites without being intercepted.

In reality, interceptors can never be launched without some delay. It takes nearly 30 seconds for an ICBM to rise above cloud cover and for early-warning missile tracking satellites to recognize the launch of an ICBM.[16] After that, depending on the location of tracking radars, it can take as long as a couple of minutes for the system to calculate the point at which it will intercept the target missile. It seems that the closest radar that can track Russian ICBMs is the Fylingdales upgraded early-warning radar located in the United Kingdom. This radar would start tracking Russian ICBMs just as their powered flight ends, approximately three minutes after being launched.[17] Some Russian experts, however, have indicated that the Globus II X-band radar in the city of Vardo, Norway, which is much closer to Russia, also could be utilized in missile defense operations against Russia.[18] These Russian experts claim that the Norwegian radar will begin tracking Russian ICBM flight trajectories 140 seconds after launch.

In order to account for these real-world operational delays, the same modeling described above was repeated with a delay of 155 seconds. That time period was chosen because an additional time of at least 15 seconds is needed from the start of tracking (140 seconds) to calculate an intercept point and launch the interceptor. The interceptors in Poland have no capability to intercept Russian ICBMs with a time delay of 155 seconds. This would have been the case even if the SM-3 IIB interceptors were in place. Because of the distance of Russia from the Polish site, a time delay greater than 45 seconds would guarantee that interceptors from that site could not hit Russian ICBMs.

The March 15 decision by the Obama administration to cancel the planned deployment of SM3-IIB interceptors, the fourth phase of the phased adaptive approach, has effectively removed any possibility that these interceptors based in Poland and Romania could be a threat to Russia. Russia, however, also has expressed concerns that Aegis-equipped ships with the SM-3 IIA interceptors, which have a velocity of 4.5 kilometers per second, located in the North Sea and the Barents Sea could pose a threat to its deterrent. Under a number of ideal and therefore unrealistic conditions, including immediate launch of the interceptors in response to the launch of the target missiles, ships located at these two positions would be capable of intercepting some ICBMs traveling on trajectories from Russia toward the United States. The threat dissipates again if one assumes a time delay of 155 seconds (fig. 2). Furthermore, during a real attack, Russia would be able to deploy multiple missiles and countermeasures that would make interception even more difficult. If the interceptors are not able to hit Russian ICBMs without taking these factors into account, as the modeling shows, then the interceptors will not be able to do so when they come into play in a real-world scenario.

Some experts within Russia support the argument presented above. In a number of articles, these experts have said that, in a hypothetical strike against U.S. territory, Russian ICBMs cannot under any circumstances end up within reach of the missile interceptors in Romania and that ICBMs from Kozelsk in western Russia can be intercepted by the missile interceptors in Poland only if they are aiming for the U.S. East Coast. Furthermore, these experts have said that other missile divisions in western Russia, such as those deployed at Vypolzovo, Teykovo, Tatishchevo, Yoshkar-Ola, and Dombarovskiy, could possibly be threatened only by ship-based missile defense systems from the waters of the Baltic, Barents, and Norwegian seas. Yet, the farther east the Russian missile division is located, the more hypothetical this threat becomes. According to these Russian analysts, inasmuch as it is the midcourse, or space, phase of ICBM trajectories that will pass over those seas, even the ship-based missile defense systems in present form are incapable of reaching these missiles.[19]

Although the cancellation of the planned deployment of the SM-3 IIB interceptors has removed the possibility that interceptors deployed under the phased adaptive approach would pose a threat to Russian missiles, it has not diminished the missile defense system’s primary mission of intercepting an array of current and potential future Iranian missiles (fig. 3). The restructured missile defense system would still theoretically be able to handle these Iranian missile threats, even if one factors in a comfortable amount of time for detecting and tracking them.

Moving Forward

The phased adaptive approach in its currently planned form would not have any effect on Russia’s nuclear deterrent. Nevertheless, a number of policy actions to ease Russian concerns have been suggested by experts in Russia and the United States. Giving Russia access to interceptor data, such as burnout velocity, is one of the prominent suggestions.[20] Given the now-reduced maximum velocity of the current system, however, it is not clear what data the United States could provide to the Russians that they could not discern on their own and that would provide them with a greater reassurance about the capabilities of the interceptors deployed under the phased adaptive approach. Russia possesses, among other means, its own early-warning satellites that it can use to monitor and estimate the characteristics of interceptors deployed under the phased adaptive approach.[21] Also, as described above, even under ideal conditions, the currently planned U.S.-NATO system does not pose any potential threat to Russia. Additional data are not needed to determine this.

It might be necessary to reassure Russia about the future evolution of U.S. missile defense systems in order to convince Moscow to engage in negotiations on further bilateral nuclear arms reduction. It is conceivable that Russia is concerned about the possibility of a very ambitious and hostile U.S. effort to employ missile defenses against it in the future. Earlier this year, Medvedev said, “We do not want next generations of politicians in 2019 or 2020 to take decisions which would open a new page in the arms race. But such a threat exists and everyone in Russia and the United States should understand this, that’s why we still have chances to come to an agreement.”[22]

In order for the phased adaptive approach to threaten Russia in a meaningful fashion in the future, not only would the United States have to deploy Aegis-equipped ships at difficult-to-operate locations such as the North Sea and Barents Sea, but it also would have to succeed in some of its ambitious plans for the development of space-based missile defense sensors.

In particular, the Precision Tracking Space System (PTSS) that was planned for launch in 2017 was touted as a sensor that would have been able to provide more-precise missile tracking much earlier in flight than current systems. If the PTSS sensors had been able to reduce interceptor response times to less than 155 seconds, the Aegis-equipped ships equipped with SM-3 IIB interceptors located in the North Sea and Barents Sea would have had the ability to intercept Russian ICBMs.[23] The PTSS, however, has been canceled because of its “significant technical, programmatic, and affordability risks.”[24] Without these advanced sensors, it would not be possible for the United States to reduce the time delays to values small enough to successfully intercept Russian ICBMs. Also, the initial SM-3 IIB conceptual designs with liquid-fueled boosters were unsafe for deployment on Navy ships.[25]

Yet, it might still be prudent to reassure Russia that future U.S. missile defense systems will not affect its deterrent. The United States could bolster the offer of a political agreement that U.S. missile defenses are not aimed at Russia by voluntarily limiting the operational scope and reach of its future space-based missile defense sensors and missile defense interceptors. Developing a joint data exchange center[26] focused on monitoring missile launches might be useful, particularly if it will demonstrate to Russia the limitations of current U.S. early-warning and missile tracking systems.

In conclusion, the U.S. policy decision to eliminate the planned deployment of SM-3 IIB interceptors from plans for missile defense in Europe has removed any potential capability to intercept Russian ICBMs bound for the continental United States. The two countries should utilize the opportunity provided by this policy decision to begin discussions on further bilateral nuclear arms reduction.

U.S. Names Possible Missile Defense Sites

The Defense Department announced last month that it has identified five possible locations in the eastern United States for a new ballistic missile defense interceptor site, but said it still has no plans to actually build such a site.

Tom Z. Collina

The Defense Department announced last month that it has identified five possible locations in the eastern United States for a new ballistic missile defense interceptor site, but said it still has no plans to actually build such a site.

In a Sept. 12 letter to members of Congress, U.S. Missile Defense Agency Director James D. Syring wrote that his agency is “conducting a study of possible additional locations to determine their suitability for a potential future interceptor deployment site.” The five candidate sites are Fort Drum in New York, Camp Ethan Allen Training Site in Vermont, SERE Training Area at Naval Air Station Portsmouth in Maine, Camp Ravenna Joint Training Center in Ohio, and Fort Custer Training Center in Michigan.

Madelyn Creedon, assistant secretary of defense for global strategic affairs, told Reuters on Sept. 12 that no decision had been made to build an additional site for missile interceptors and there was no money to do so in the Pentagon’s future budget plans. Because of the automatic spending cuts known as sequestration, “we get very worried about whether or not we’re even going to have enough money to do what we’ve decided to do,” she said, adding that an additional interceptor site would be “extraordinarily expensive.”

In a June 10 letter to Capitol Hill, Syring wrote, “There is no validated military requirement to deploy an East Coast missile defense site.” (See ACT, July/August 2013.)

Congressional Republicans have been pushing the Obama administration to build a missile defense site on the East Coast in addition to existing sites at Fort Greely in Alaska and Vandenberg Air Force Base in California. Proponents of a new site say the United States needs better defenses against a possible missile attack from Iran. Opponents counter that Iran does not have long-range missiles capable of reaching the United States and, if it did, the West Coast sites could intercept them. Others argue that the West Coast system is ineffective and would be no more effective if fielded in an eastern state.

In the 2013 defense authorization law, Congress required the Defense Department to identify three possible new interceptor sites, including at least two on the East Coast. The department has a congressionally mandated deadline of Dec. 31 to decide which of the five announced sites to include in an environmental impact study expected to take 18 to 24 months. All of the sites are on federal land, operated by the Defense Department, the National Guard, or both.

Key Missile Defense Test Delayed

Tom Z. Collina

In the wake of a failed July 5 intercept attempt, the Defense Department has delayed an upcoming missile defense test that will help determine if it can move ahead with plans to field additional long-range interceptor missiles in Alaska by 2017. Originally planned for this fall, the trial launch will not take place until March, according to July 17 testimony from the director of the Pentagon’s Missile Defense Agency (MDA).

Testifying before the Senate Appropriations Defense Subcommittee, MDA Director Vice Adm. James Syring said that the March 2014 test “must” be completed successfully before the Defense Department carries out its plans to increase the number of ground-based interceptor (GBI) missiles deployed in Alaska and California from 30 to 44 by 2017. That planned increase, announced March 15, was motivated by recent missile and nuclear tests by North Korea. (See ACT, April 2013.)

“We need to know these missiles perform as advertised, through rigorous intercept tests,” Syring said of the 14 new interceptors, which will cost $1 billion.

In July 30 comments to reporters, Sen. Richard Durbin (D-Ill.), who chairs the defense appropriations panel, also emphasized the need for further testing. “Before we go forward on missile defense, we need a successful test, period,” he said. “Before we expand the missile defense layout to include the East Coast, we need a pretty fulsome debate after a successful test,” he said, referring to Republican proposals to field a new missile interceptor site in a northeastern state. (See ACT, July/August 2013.)

Since 1999, according to the MDA, GBI missiles have hit their target in eight out of 16 attempts. This record falls short of other missile defense systems, such as the Aegis system based on ships, which has hit 25 of 31, or the Terminal High Altitude Area Defense system, which is 10 for 10. All of these tests are conducted in a “controlled, scripted environment,” Syring said.

The additional 14 GBI missiles for Alaska would be armed with a newer version of the system’s exoatmospheric kill vehicle (EKV), known as the Capability Enhancement-II (CE-II). The CE-II has never had a successful intercept test, having failed twice in 2010. Nonetheless, CE-IIs are already deployed on 10 of the 30 GBI missiles.

The EKV, a key part of the GBI system, is lifted into space by a booster rocket and is designed to use its onboard sensors to locate an incoming enemy warhead and destroy it on impact.

Surprise Failure

The subject of the failed July 5 test was not the CE-II, but the CE-I, which sits atop 20 GBI missiles and had not been flight-tested since 2008. Because it had successfully hit the target in three previous tests, this failure came as a surprise. In the latest test, which cost about $200 million, the CE-I did not separate from the booster’s third stage, Syring testified. The MDA is conducting a review, which is expected to take several months, to confirm the cause of the failure and has not determined when a retest might take place.

James Miller, undersecretary of defense for policy, said at a July 17 Capitol Hill forum that he “would like to see a test of both versions” of the EKV in the next 12 months and that he still expected to reach the goal of 44 deployed GBI missiles by 2017.

An MDA spokesman told Arms Control Today in a July 29 e-mail that the July 5 CE-I test failure was not directly responsible for the postponement of the CE-II test to March. He attributed the delay to the need for more time to fix issues arising from the last failed CE-II test in December 2010. But he said that the MDA wanted to wait for the review of the July 5 test to be completed before conducting any more GBI tests, as the two EKVs use the same rocket booster.

Schedule Pressure

At the July 17 hearing, Durbin said the GBI system had performed poorly because it had been rushed into deployment by the Bush administration in 2004. “There was deployment before development” for the GBI missile, which was not the case for Aegis, Durbin said.

Syring agreed, saying that the “schedule-driven pressure to get interceptors in the ground” led to “the decision to field what were prototypes” with the intent to improve them over time. That, Syring said, led to the development of the CE-II, which was an upgrade to the GBI system that was fielded “very, very quickly.”

According to the MDA, the Pentagon is spending more than $1 billion in remedial efforts to get the CE-II interceptor to work, including the two failed 2010 tests, failure reviews, a nonintercept test in January, and the test planned for March.

Friday's Missile Defense Test: What Will It Mean?

Missile interceptor test lights up the night sky By Tom Z. Collina In its own multi-million dollar display of fireworks, the U.S. Missile Defense Agency (MDA) will conduct an intercept test of the Ground-Based Interceptor (GBI) system on Friday, July 5. This will be the first test of the system's ability to hit a mock target since two failures in 2010. The last successful intercept was in 2008. However, this is not the key test that will determine if the Pentagon can go ahead with its $1 billion-plan to field 14 additional GBIs in Alaska by 2017, as announced by Defense Secretary Hagel in...

Pentagon: New Missile Site Unneeded

The Pentagon said it does not need a new missile defense site on the East Coast, but the House approved funding for a new site, drawing a presidential veto threat.

Tom Z. Collina

In a setback to congressional proponents of a new missile interceptor site on the U.S. East Coast, senior military officials wrote in June that there is no military requirement for such a site and that the funds would be better spent on improving sensor capabilities for the existing system of interceptor sites in Alaska and California.

“There is no validated military requirement to deploy an East Coast missile defense site,” wrote Vice Adm. James Syring, director of the Missile Defense Agency (MDA), and Lt. Gen. Richard Formica, commander of the Joint Functional Command for Integrated Missile Defense, in a June 10 letter to Sen. Carl Levin (D-Mich.). They told Levin, chairman of the Armed Services Committee, that a decision to build such a site should wait until an environmental review of possible locations, required by the fiscal year 2013 National Defense Authorization Act, is complete. In May, Syring testified that this review, which would start in early 2014, could take up to two years.

Compared to another missile interceptor site, investments in “discrimination and sensor capabilities” would be a “more cost-effective” way to better protect the United States from long-range ballistic missiles, Syring and Formica wrote. Independent experts have criticized the U.S. system for not having the sensors, such as X-band radars, that would be necessary to distinguish actual threat warheads from missile debris and other decoys. Michael Gilmore, director of operational testing and evaluation at the Pentagon, testified May 9 that “[i]f we can’t discriminate what the real threatening objects are, it doesn’t matter how many ground-based interceptors we have. We won’t be able to hit what needs to be hit.”

The United States already has two missile interceptor sites on the West Coast, at Fort Greely in Alaska and Vandenberg Air Force Base in California, with a total of 30 ground-based interceptor (GBI) missiles to blunt potential limited attacks from North Korea or Iran. North Korea has long-range missiles that may be capable of reaching the United States; Iran could have such capabilities by 2015 with foreign assistance, according to U.S. intelligence agencies.

In response to recent North Korean nuclear and missile tests, the Pentagon announced in March that it would field an additional 14 GBI missiles in Alaska by 2017 at a cost of $1 billion, using funds that would have been allocated for the now-canceled Standard Missile-3 (SM-3) IIB missile that had been planned for deployment in Europe. (See ACT, April 2013.) The GBI missiles would also be effective against future missile threats from Iran, according to the Defense Department.

Madelyn Creedon, assistant secretary of defense for global strategic affairs, testified in May that the East Coast is already “well protected” by the 30 GBI missiles now deployed and that the plan for another 14 interceptors “provides additional protection” against “anything from North Korea as well as anything from Iran, should that threat develop.”

The combat effectiveness of the current GBI system has not been proven. The system has not successfully intercepted a test target since 2008, with two failures in 2010. (See ACT, October 2012.)

Meanwhile, the Senate Armed Services Committee approved its version of the defense authorization bill June 13. Like last year, the Democratic-led Senate did not authorize an East Coast site. Instead, reflecting the June 10 letter from the Pentagon, the committee’s bill authorizes $30 million to deploy an additional X-band radar to support target discrimination. The administration had not requested those funds. Overall, the committee authorized $9.3 billion for missile defense, $150 million more than what the administration had requested.

Levin told reporters June 13 that his committee had authorized funds to build “advanced sensors” that would be “more effective than just missiles.” Levin said the sensors would be cheaper than a new missile interceptor site and that “they can be fielded faster.”

Despite the Pentagon’s position, on June 14 the full Republican-controlled House of Representatives voted, as it did last year, to fund an East Coast missile defense site in its fiscal year 2014 defense authorization bill, providing $140 million to begin site construction. The House Appropriations Defense Subcommittee put $70 million in its 2014 spending bill for the same purpose.

The House authorization bill says a new site is needed “to deal more effectively with the long-range ballistic missile threat from the Middle East,” particularly Iran. Missile defense proponents in the House say that the need has increased since the Obama administration canceled the SM-3 IIB program, which would have been fielded in Poland to intercept potential long-range missiles from Iran aimed at the United States.

On June 11, after a House Armed Services Committee vote, the White House threatened to veto the House defense bill on the grounds that the call for an East Coast site “presumes a validated military requirement…when none exists.”

An East Coast site would cost at least $3.4 billion to build and operate over five years, according to a June 11 Congressional Budget Office estimate. A 2012 report by the National Research Council, the operating arm of the National Academy of Sciences, said that the total 20-year cost for a new system at two sites would be up to $25 billion and that the United States has already spent about $40 billion on the system on the West Coast. The report recommended replacing the existing system with an entirely new technology, which could take a decade or more to develop.

Once the full Senate approves its defense authorization bill, the House and Senate bills will have to be brought into agreement by a conference committee before being sent to President Barack Obama.

Statement on President Obama's June 19 Address in Berlin on Eliminating Nuclear Weapons Threats



President Barack Obama's proposals today in Berlin for cutting the oversized U.S. nuclear arsenal and reducing global nuclear weapons dangers are welcome and overdue.


For Immediate Release: June 19, 2013           
Daryl G. Kimball, executive director, 202-463-8270, ext. 107

(Washington, D.C.)--President Barack Obama's proposals today in Berlin for cutting the oversized U.S. nuclear arsenal and reducing global nuclear weapons dangers are welcome and overdue.

Since the days of the Kennedy administration, U.S. leadership to reduce and eliminate the nuclear threat has been critical. To succeed, however, Obama and his team will need to sustain high-level focus and energy on these urgent and tough nuclear security challenges.

The United States can and should reduce its arsenal well below 1,000 deployed strategic warheads, which is still more than enough nuclear firepower to deter any current or potential nuclear adversary. The "one-third" cuts outlined by the President are a good start, but it is only 200-300 warheads fewer than the United States was prepared to agree to during the New START negotiations four years ago.

U.S.-Russian nuclear reductions need not wait for a formal follow-on treaty. The two presidents could achieve similar and more rapid results through parallel, reciprocal reductions of strategic warheads--to well below 1,000 within the next five years, which could be verified under the 2010 New START treaty.

Bipartisan national security leaders agree that further, deeper nuclear reductions would increase U.S. security, lead to budget savings, and help pressure other nuclear-armed states to join in the disarmament enterprise.

Further nuclear reductions would also allow the administration to scale back unaffordable, overly ambitious Pentagon plan for building a new generation of strategic nuclear delivery systems and rebuilding five types of nuclear warheads. A 2013 assessment by the Arms Control Association identifies $39 billion in taxpayer savings over the next decade if the United States right-sizes its nuclear force to 1,000 or fewer strategic deployed nuclear warheads.

The President should also provide stronger leadership to overcome NATO and Russian inertia regarding tactical nuclear weapons. More than 20 years after the end of the Cold War, there is no military rationale for Russia to maintain some 2,000 tactical nuclear bombs, half of which are on obsolete naval and air defense systems. Nor is there any military requirement for the U.S. to keep 180 air-delivered nuclear bombs in Europe, which could cost $8 billion or more to refurbish. The President should begin the process of removing the U.S. tactical bombs and call on Russia to reciprocate.

Stronger U.S. leadership is also necessary to stop the spread of nuclear weapons.  

The President must put renewed energy behind the on-again-off again negotiations to limit Iran's nuclear potential and achieve a more effective inspections system. There is time for diplomacy but that time should not be wasted. The President also needs to re-engage North Korea in serious talks to halt its nuclear and missile programs, which have and can again reduce the threat it poses to Asia and to the nuclear Nonproliferation Treaty.

The President's renewed commitment to U.S. ratification of the Comprehensive Test Ban Treaty (CTBT)--which prohibits all nuclear test explosions anywhere--is important and welcome, but requires serious follow-though to win the support of the Senate.

Since the days of Presidents Eisenhower and Kennedy, a ban on nuclear testing has been a U.S. national security objective. Today, a legally binding, verifiable ban on all nuclear testing is vital to prevent states from improving their existing arsenals and it would make it harder for potential nuclear powers like, like Iran, to perfect deliverable nuclear warheads in the future.

In 2009, Obama said his administration would pursue "immediate and aggressive" steps to secure ratification and there is strong support for action from bipartisan national security leaders and U.S. allies. Ratification is possible if the administration launches the kind of effort it successfully pursued to win approval of the New START agreement in 2010.

To get the process started, President Obama should announce the appointment of a senior, high-level White House CTBT coordinator, or task force, within the next several weeks. This would help to engage Senators on the issues surrounding the CTBT and begin the fact-based conversation that such important matters deserve.

The President's decision to extend the Nuclear Security Summit to a fourth meeting in 2016 is very important and should help plug the remaining gaps in the global nuclear security regime.

While the Obama administration has focused high-level attention to the threat posed by nuclear terrorism and spurred important progress globally to lock-down vulnerable stockpiles, the current system still lacks universal standards and reporting requirements. President Obama should take this opportunity to bolster the nuclear security enterprise and augment funding for vital U.S. nuclear threat reduction programs in the years ahead.

As President Kennedy said five decades ago, "the weapons of war must be abolished before they abolish us." Today every man, woman and child still lives under a threat of nuclear war through accidents, miscalculation, or terrorist madness.

In the months ahead, President Obama must re-energize and sustain the nuclear risk reduction enterprise and U.S. policymakers must overcome partisan politics to help address today's grave nuclear challenges.--Daryl G. Kimball
