PACOM Commander Admiral Keating is “unaware” of the Japanese interest in the nuclear Tomahawk cruise missile reported by the Congressional Strategic Posture Commission.

By Hans M. Kristensen

Admiral Timothy J. Keating, who is Commander of U.S. Pacific Command, said Tuesday that he is “unaware of specific Japanese interests in the” nuclear-armed Tomahawk Land-Attack Missile.

That’s interesting because the Congressional Strategic Posture Commission recently pointed explicitly to such a Japanese interest in the role that the missile – known as the TLAM/N – provides in extending a U.S. nuclear umbrella over Japan to deter nuclear attacks against it from China and other potential adversaries in the region.

We would expect the commander of Pacific forces to be in close contact with the highest levels of the Japanese government and military.  Shouldn’t he be aware of a specific Japanese interest in specific weapons for the U.S. nuclear umbrella?  So statements to the contrary in the recent Congressional Commission report seem odd and worth investigating.

It was reported this week that the Presidents Council on Bioethics was disbanded. The Council, appointed by the Bush Administration, was often accused of taking a more ideological than scientific perspective in its reports and advice. In its place, President Obama will convene a new bioethics commission.

North Korea mistakenly believes there are U.S. nuclear weapons in South Korea.

By Hans M. Kristensen

The North Korean newspaper Rodong Sinmun reportedly has issued a statement saying the U.S. has 1,000 nuclear weapons in South Korea. In this regional war of rhetoric it is important to at least get one fact right: The United States does not have nuclear weapons in South Korea. It used to – at some point close to 1,000 – but the last were withdrawn in 1991.

The only nuclear weapons the United States has in the Pacific today are the hundreds of warheads deployed on Trident II D5 sea-launched ballistic missiles on board eight Ohio-class nuclear-powered submarines patrolling in the Pacific Ocean. Some of them may be earmarked for potential use against targets in North Korea. Other weapons for bombers could be moved into the region if necessary, but they’re not today.

The North Korean obsession with the U.S. nuclear “threat” might be seen as confirmation that the nuclear deterrent works and hopefully will deter North Korea from attacking anyone. But the flip side of the coin is to what extent the U.S. nuclear posture in the Pacific – past and present – helps feed the North Korean nuclear rhetoric and perhaps even ambitions.

The NASIC report dispels many web-rumors.

By Hans M. Kristensen

The Air Force Air and Space Intelligence Center (NASIC) has published an update to its Ballistic and Cruise Missile Threat. The document, which I obtained from NASIC, is sobering reading.

The latest update continues the previous user-friendly format and describes a number of important assessments and new developments in ballistic and cruise missiles of many of the world’s major military powers.

The report also helps dispel many web-rumors that have circulated about Chinese, Russian, Indian and Pakistani nuclear forces.

In this blog I’ll focus on the nuclear weapon states, particularly China.

An article in USNI, which carries this photo of USS Hartford (SSN-768) damaged in a recent collision, discusses China’s ballistic missile submarines.

By Hans M. Kristensen

The magazine U.S. Naval Institute Proceedings has an interesting article about China’s nuclear ballistic missile submarines written by Andrew S. Erickson and Michael Chase from the U.S. Naval War College. And I’m not just saying that because they reference several of my publications about China, but because they provide an interesting discussion of the possible motivations for China’s emerging sea-based nuclear force.

I, for one, have always wondered why, if China’s current strategic modernization is intended to reduce the vulnerability of its long-range nuclear deterrent, would China want to cluster a significant portion of its missiles on a few submarines and send then out to sea where U.S. attack submarines can hunt them down?

In theory a sea-based nuclear deterrent is invulnerable because it can hide. But given that the U.S. Navy’s Maritime Strategy in the 1980s was explicitly designed to find and sink Soviet ballistic missile submarines before they could launch their missiles, how secure will China’s sea-based nuclear deterrent actually be? Or how would China react in a crisis, if one of the submarines went missing due to an accident?

The North Korean nuclear test on May 25, 2009, was “heard” loud and clear around the world despite its apparent limited size. Detection of small, clandestine nuclear tests seems to work.

By Hans M. Kristensen

The Korean Central News Agency reportedly has announced that North Korea “successfully conducted one more underground nuclear test on May 25 as part of measures to bolster its nuclear deterrent for self-defense.”  Several news media reported that the Russian Ministry of Defense estimating the test had a yield of approximately 10 to 20 kilotons.

Yet the preliminary seismic data published by the U.S. Geological Survey (USGS) shows that the test had a seismic magnitude of 4.7, only slightly more powerful than the 4.3 of the 2006 test.

Was it another fizzle? We’ll have to wait for more analysis of the seismic data, but so far the early news media reports about a “Hiroshima-size” nuclear explosion seem to be overblown.

Update: CTBTO’s initial findings.

On Wednesday, the FBI thwarted an alleged terrorist plot to shoot down a military cargo plane with a Stinger missile.  According to a criminal complaint obtained by the New York Times, four men were arrested on charges of conspiring to use “a surface-to-air missile system to destroy military aircraft at the New York Air National Guard Base located at Stewart Airport in Newburgh, New York. “ The plot also allegedly included plans for a simultaneous attack on a Bronx synagogue using an improvised explosive device containing more than 30 pounds of C-4 explosives.

The FBI operation in New York is one of several since the 1980s in which undercover US agents have thwarted  attempts to smuggle, acquire or use man-portable air defense systems (MANPADS), including US-made Stinger missiles.  These plots feature conspirators that range from rank amateurs whose ability to obtain MANPADS is dubious at best to sophisticated criminals with a demonstrated ability to obtain and ship weapons to bad actors worldwide.  An example of the former is Hemant Lakhani, a British merchant born in India who was arrested in 2003 for attempting to import 200 Russian Igla missiles into the US and to sell them to individuals claiming to be members of a Somali terrorist organization.  Lakhani was so inept that undercover Russian agents ended up furnishing him with a (deactivated) SA-18 missile after he repeatedly tried and failed to obtain a missile himself.  The agents then had to reroute the missile after Lakhani arranged to have it delivered to the wrong address.

Today Science Magazine is reporting that the Army has banned all pathogen research at one of its labs at the Armed Forced Institute of Pathology (AFIP) in Washington, DC. This decision was made December 2, 2008 as a result of an earlier failed Biological Surety Inspection, and not made public.

Science reports that “officials found that lab managers ignored information about certain employees that could have disqualified them from having access to dangerous pathogens. The redacted version of the IG’s [Inspector General's] report released to Science does not divulge the nature of this so-called potentially disqualifying information, but it could be anything from alcoholism to mental instability.”

On October 28, 2008 AR 50-1 came into effect, stipulating a strict Biological Personnel Reliability Program for DOD employees as part of their Biological Surety Program. It includes and intense background investigation and interviews  of employees as well as regulations regarding substance abuse and mental health.

In early February the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) also suspended its research on biological select agents and toxins when it was realized that there were problems with the system of accounting for high risk microbes and biological materials in the laboratories at Fort Detrick, MD.

The Congressional Commission on the strategic posture report released yesterday is what the Air Force calls a “target rich environment.” There is a lot to shoot at. This essay follows up on the post that Hans Kristensen and I published yesterday. I want to continue the theme I discussed yesterday that the recommendations of the report are based on assumptions about nuclear weapons characteristics, assumptions that are implicit, unexamined, and unsupportable.
