New Report: After Over $30 Billion Spent, U.S. Missile Defense Still Has Serious “Shortcomings”

By Tom Z. Collina

A report by the National Research Council (NRC) released today finds that the US Ground-based Missile Defense (GMD) system deployed Alaska and California has “shortcomings” so serious that it recommends the system be completely redesigned, rebuilt and retested.

The US taxpayer has spent over $33 billion on the current GMD, according to the report, which was funded by the Pentagon’s Missile Defense Agency.

Moreover, the report finds that “boost-phase” missile defense concepts will not work and that resources should be focused on mid-course intercept, where incomming targets are intercepted in space. Even so, the report notes that an effective mid-course system must confront the “discrimination challenge,” which means it must be able to tell the difference between real target warheads and decoys.

All mid-course intercept plans are vulnerable to decoys and other countermeasures, for which no answer has been found after decades of trying.

Given the report’s scathing assessment of current missile interceptor technology, it is surprising that the report calls for not one but two east coast missile interceptor sites as part of a revamped system.

After the report’s conclusions were first released in April, the Republican-controlled House Armed Services Committee (HASC) voted in May to build a third strategic missile interceptor site on the East Coast by the end of 2015. This proposal ignores the NRC’s findings and threatens to waste yet more tax revenue.

House Republicans, such as Rep. Michael Turner (R-Ohio), are cherry-picking the NRC’s results to support their position.

NRC’s recommendations make it clear that the current West Coast interceptor system is not effective and would have to be completely redesigned, retested and rebuilt before it could be installed on the East Coast. HASC’s requirement to deploy the third site by late 2015 is thus highly unrealistic.

The United States already has two GMD sites on the West Coast, with 30 interceptors deployed in California and Alaska, to handle a potential attack from North Korea and Iran. The GMD system has not had a successful intercept test since 2008, with two failures in 2010.

The Obama administration is building another interceptor system in Europe, known as the Phased Adaptive Approach (PAA), to handle potential attacks from Iran. The system’s Phase IV, to be deployed in 2020, would seek to intercept long-range missiles that could reach the United States. Neither North Korea nor Iran has yet deployed long-range missiles that could reach the United States.

The main conclusions of the NRC report, called Making Sense of Ballistic Missile Defense: An Assessment of Concepts and Systems for U.S. Boost-Phase Missile Defense in Comparison to Other Alternatives, were made public in an April 30, 2012 letter from committee co-chairs L. David Montague and Walter B. Slocombe to the chairman and ranking member of the HASC.

The letter states that, “The current GMD system has serious shortcomings, and provides at best a limited, initial defense against a relatively primitive threat. However, it can be fixed.” To do so, the NRC suggests a new two-stage Ground-Based Interceptor (GBI) that is smaller and faster (6 km/sec) than the current GBI and a new “more capable” kill vehicle. In other words, their “fix” includes a completely new interceptor system, which will take significant time and money to develop.

Only after the new interceptor and kill vehicle are ready, then the NRC says the system could be deployed initially at a third and fourth site in the northeastern and north central part of the U.S., and thereafter used to replace the GBI system on the West Coast, for a total of 100 deployed interceptors. No timeframe is given. Current GBI’s would be used as test targets.

The NRC report states that this plan would make Phase IV of the European PAA redundant, and thus that phase should be cancelled. In addition, the Bush administration’s plan (since abandoned by the Obama administration) for a third site in Poland would not have been effective as it would have used a derivative of the GBI, which the committee recommends replacing.

In addition, the NRC report found that boost-phase intercept is not feasible, and thus mid-course intercept is the most promising means of intercepting long-range ballistic missiles. The NRC analysis raises some crucial points that actually undercut arguments for an East Coast site:

* The current West Coast GMD system is not working and needs to be replaced, and a third site should not be built until new technology is developed and tested. Such a process is not likely to be completed by HASC’s deadline of late 2015.

* The proposed East Coast site is an alternative to EPAA Phase IV; we do not need both.

* The East Coast system, like all mid-course intercept plans, would be vulnerable to decoys and other countermeasures, for which no answer has been found after decades of trying.

One Response to New Report: After Over $30 Billion Spent, U.S. Missile Defense Still Has Serious “Shortcomings”

  1. Raoul D. Revord, J.D. , Ph.D. says:

    The world’s greatest defense to a nuclear winter would be a system or method of de-valuing the existence of nuclear arsenals, preventing any one or more nuclear weapon states from having the technical means of launching a first-strike against an adversary, while engaging in a sustained verifiable program of complete nuclear disarmament.
