China has test launched a DF-31 long-range ballistic missile, according to a report by the Russian news agency ITAR-TASS. The missile was said to have been launched from the Wuzhai launch site on Monday night.

The DF-31 has been under development since the 1980s and Monday’s flight test appears to be the sixth flight test of the missile since 1999. The U.S. Department of Defense predicted in 2002 that the DF-31 would be deployed “before mid-decade,” but that didn’t happen. The current DOD prediction is that deployment may happen this year. Some web sites erroneously say the missile is already operational.

The DF-31 forms the core of China’s current modernization of long-range nuclear ballistic missiles. Two modifications of the DF-31 are under development. The road-mobile DF-31A has a longer range (possibly up to 12,000 km), and the 8,000+ km range Julang-2 is intended to arm China’s next generation of ballistic missile submarines (Jin-class).

There is considerable confusion and uncertainty about the capability of the DF-31. Early reports predicted a range of at least 8,000 km (4,875 miles), but the latest DOD estimate is 7,250+ km (4,500+ miles). China has not yet tested the DF-31 to the full range reported by the DOD. Tuesday’s test launch impacted in the Takla Makan Desert some 2,500 km west of Wuzhai. If the range is 7,250+, the DF-31 will not be able to target the entire continental United States, only the most northwestern parts. Its main role may be against Russia, India, as well as U.S. facilities in the Pacific including Hawaii and Guam.

Another confusion concerns the payload. Despite widespread speculation among private analysts and media that the new missiles will carry multiple warheads, the U.S. intelligence community anticipates that all three missile types will carry a single warhead each.

Later this month (September), FAS and the Natural Resources Defense Council will publish a joint report about Chinese nuclear forces and U.S. nuclear targeting of China. The report uses high-resolution satellite images and declassified documents to describe the nuclear relationship between China and the United States.

Last week the House of Representatives debated and passed the United States and India Nuclear Cooperation Promotion Act of 2006. I think that most of the debate missed what I consider the most important points.

First of all, I should emphasize that every Congressman, even those most strongly opposed to the deal, introduced their remarks with praise for India. I have not yet come across any American commentator anywhere who does not feel that it is natural and desirable for the United States and India to have closer ties. I think that one of the great tragedies of the Cold War was that the United States and India seemed early on to have got their wires crossed because of misjudgments on both sides. The one issue on which everyone seems to agree is that India and the United States should be friends. Some of the Congressional comments in fact went a bit overboard. Congressman Davis of Illinois said, “India is a flourishing democracy that seeks to develop its nuclear program for purely peaceful reasons,” which is, of course, patently false—the purely peaceful part—but never mind, it fit the tone of the debate.

Update (February 22, 2007): DTRA announces that Divine Strake has been canceled.

The controversial Divine Strake explosion has been delayed again, this time “at least several months into calendar year 2007,” according to a statement distributed in Congress by the Defense Threat Reduction Agency. “We have stood down the experiment site and the workforce that was preparing the site for the experiment,” DTRA said.

The delay comes after DTRA told Senator Orrin Hatch (UT) that it will “look into the possibility of other locations” for conducting the Divine Strake test.

Divine Strake was initially scheduled to take place on June 2, 2006, but disclosure that the experiment was in fact intended to calibrate the use of low-yield nuclear weapons against underground targets, combined with lawsuits from local communities, caused the government to withdraw its “no impact” environmental assessment shortly before the scheduled test and delay it until September 2006.

Although DTRA has repeatedly stated that the experiment did not pose an environmental hazard, the agency now says that it is “developing a plan that would permit the conduct of the DIVINE STRAKE experiment if it is determined that the experiment can be conducted safely, is in compliance with NEPA, and there is a favorable court ruling.”

The decision to possibly move the test to another location is especially interesting because the current site was “carefully chosen” so that it “simulates the characteristics of important potential, global adversaries,” according to the DOE’s environmental assessment: “As a number of potential adversarial military targets are based in similar limestones, [Divine Strake] needed to be sited in a similar geological setting to actual military targets.” Previous high-explosive tests have been conducted at the White Sands Missile Range in New Mexico and at Misers Bluff at Planet Ranch in Arizona. We’ll see what Senator Pete Domenici from New Mexico and Jon Kyl from Arizona say about that.

The DTRA statement is not available on the web sites of DTRA, NNSA, or the Nevada Test Site. A search for Divine Strake on DTRA’s site gave “no results.” An on-line Divine Strake briefing previously posted on the DTRA web site has also been removed.

On Wednesday, the House of Representatives passed overwhelming, 359 to 68, a bill that sets out procedures for nuclear trade with India (the link includes the House floor debate and the text of the bill, about a third of way down). It is an entirely different bill than that proposed by the White House. The White House’s suggested bill was an insult to Congress, essentially asking Congress to cede any review rights and to approve details of the nuclear deal that haven’t even been decided yet. Whatever members of Congress thought about the India-US nuclear deal, they were not going to just leave the rubber stamp on the White House steps. The House bill, H.R. 5682, clearly rebukes the President on his request for pre-approval. The ultimate details of any agreement will have to go back to Congress for approval by joint resolution.

The French magazine Défense Nationale asked me to submit an article about the new U.S. National Military Strategy published by the Bush administration in March 2006 and how it relates to the so-called preemption doctrine announced by the administration in 2002. The article is included in the July 2006 issue which focuses on the nuclear deterrence debate following the announcement by French president Jacques Chiraq in January that France has adjusted its nuclear posture to target regional adversaries armed with weapons of mass destruction. The magazine is published by the Committee for National Defence Studies, an independent research institution which includes several retired generals and admirals from the French military.

The Pentagon is considering acquiring up to four types of Reliable Replacement Warheads (RRW), twice as many as reported so far, according to an overview discovered by the Federation of the American Scientists on a Pentagon web site.

The Department of Energy told Congress in April that Los Alamos National Laboratory and Lawrence Livermore National Laboratory were working on “an RRW design” for completion later in 2006. The Washington Post added last month that a Senate subcommittee had added $10 million to next year’s budget to fund a design of a second RRW.

According to the new DOD overview, which looks beyond 2030, the future nuclear weapons stockpile would be made up of 4-6 different types of warheads (down from nine types today). A decision would be made mid-next decade about whether to have a mix of RRWs and existing warhead types or transition to an all RRW-stockpile.

In an apparent response to the Bush administration’s decision to reduce reliance of reserve warheads and instead transition to a “responsive infrastructure” that will produce warheads when needed, the DOD plan envisions “steady-state production of warheads for deployment” in the long term.

The plan also forecasts decisions on developments of warheads for the next generation of nuclear weapon delivery systems (missiles and aircraft).

The U.S. nuclear stockpile currently contains approximately 10,000 nuclear warheads of nine principle designs: B61, W62, W76, W78, W80, B83, W84, W87 and W88. The Bush administration has decided to reduce the total stockpile “almost in half” which is estimated to leave a stockpile of some 6,000 warheads in 2012.

There have been some legislative developments on the India-US nuclear deal. The results are not what I would like to have seen but I suppose it could have been worse. On 27 June, the House International Relations Committee approved their version of the bill 37 to 5. On 29 June the Senate Foreign Relations Committee voted 16 to 2 in favor of their bill. Both bills give the administration and the Indians essentially everything they asked for except preapproval.

Although the British government has promised a full and open public debate about the future of Britain’s nuclear deterrent, it has so far failed to explain what decisions need to be made, failed to provide a timetable for those decisions, and has refused to participate in a House of Commons Defence Committee inquiry on the future of Britain’s nuclear deterrent, according to a British parliamentary report. The report partially relies on research conducted by the FAS Nuclear Information Project for the SIPRI Yearbook.

A Written Declaration presented in the European Parliament calls for the withdrawal of US nuclear weapons from Europe by the end of 2006. The Declaration has until December 10 to gather support from at least half of the Parliament’s 732 members to be adopted and formally submitted to the US government. The initiative comes as Russia refused last week to discuss tactical nuclear weapons with the United States. Most European want the US to withdraw its remaining nuclear weapons from Europe.

In an op-ed in last Wednesday’s Washington Post, IAEA Secretary General Mohammad elBaradei endorsed the US-India nuclear deal without reservation. The Secretary makes several good points but he fails to demonstrate his assertion that the deal will help reach his own objectives.

Thirty seven Nobel Laureates signed a letter opposing the administration’s proposed nuclear trade deal between India and the United States. The letter was released at a press briefing at the National Press Club yesterday.

The Federation of American Scientists was founded by scientists who had worked on the Manhattan Project to develop the first atomic bombs. The founders of FAS understood that the technology that made nuclear power possible and the technology that made nuclear weapons possible were inextricably entangled. One of the founding issues of the Federation was, therefore, openness and international inspection, if not control, of all the world’s nuclear facilities. They recognized that this was the only hope of avoiding wide-spread proliferation of nuclear weapons.

Here we are sixty years later and faced with the same issue. The Federation strongly supports improved economic, cultural, trade, academic, and security relations with India. We would like to see Chinese, as well as US, Russian, indeed, everyone’s nuclear arsenals dramatically reduced and eventually eliminated. The Indian-US nuclear deal further undermines the already weakened non-proliferation regime and pushes the world in the wrong direction, toward greater legitimacy of nuclear weapons.

The Federation of American Scientists is proud that thirty seven Nobel Laureates on its Board of Sponsors agreed to endorse this letter to Congress.

The Air Force has published a new report about the threat from ballistic and cruise missiles. The new report, Ballistic and Cruise Missile Threat, presents the Air Force National Air and Space Intelligence Center’s (NASIC) assessment of current and emerging weapon systems deployed or under development by Russia, China, India, Pakistan, North Korea, Iran, Syria and others.

Among the news in the report is a different and higher estimate for China’s future nuclear arsenal than was presented in the previous NASIC report from 2003. Whereas the previous assessment stated that China in 15 years will have 75-100 warheads on ICBMs capable of reaching the United States, the 2006 report states that this number will be “well over 100” warheads. NASIC also believes that a new Chinese cruise missile under development will have nuclear capability.

Also new is that NASIC reports that the Indian Agni I ballistic missile has not yet been deployed despite claims by the Indian government that the weapon was “inducted” into the Indian Army in 2004. Contrary to claims made by some media and experts, the NASIC report states that the Indian Bramos cruise missile does not have a nuclear capability. The Babur cruise missile under development by Pakistan, however, is assessed to have a nuclear capability.

A copy of the report, which was published in March 2006 and recently obtained by the Federation of American Scientists, is available in full along with previous versions here.
