A new report describes U.S. and Russian non-strategic nuclear weapons

.
By Hans M. Kristensen

A new report estimates that Russia and the United States combined have a total of roughly 2,800 nuclear warheads assigned to their non-strategic nuclear forces. Several thousands more have been retired and are awaiting dismantlement.

The report comes shortly before the NATO Summit in Chicago on 20-21 May, where the alliance is expected to approve the conclusions of a year-long Deterrence and Defense Posture Review that will, among other things, determine the “appropriate mix” of nuclear and non-nuclear forces in Europe. It marks the 20-year anniversary of the Presidential Unilateral Initiatives in the early 1990s that resulted in sweeping reductions of non-strategic nuclear weapons.

Twenty years later, the new report Non-Strategic Nuclear Weapons estimates that U.S. and Russian non-strategic nuclear forces are deployed at nearly 100 bases across Russia, Europe and the United States. The nuclear warheads assigned to these forces are in central storage, except nearly 200 bombs that the U.S. Air Force forward-deploys in almost 90 underground vaults inside aircraft shelters at six bases in five European countries.

The report concludes that excessive and outdated secrecy about non-strategic nuclear weapons inventories, characteristics, locations, missions and dismantlements have created unnecessary and counterproductive uncertainty, suspicion and worst-case assumptions that undermine relations between Russia and NATO.

Russia and the United States and NATO can and should increase transparency of their non-strategic nuclear forces by disclosing overall numbers, storage locations, delivery vehicles, and how much of their total inventories have been retired and are awaiting dismantlement.

The report concludes that unilateral reductions have been, by far, the most effective means to reducing the number and role of non-strategic nuclear weapons. Yet now the two sides appear to be holding on to the remaining weapons to have something to bargain with in a future treaty to reduce non-strategic nuclear weapons.

NATO has decided that any further reductions in U.S. nuclear weapons in Europe must take into account the larger Russian arsenal, and Russia has announced that it will not discuss reductions in its non-strategic nuclear forces unless the U.S. withdraws its non-strategic nuclear bombs from Europe. Combined, these positions appear to obstruct reductions rather facilitate reductions. Russian reductions should be a goal, not a precondition, for further NATO reductions.

More than two-thirds of Russia’s current ICBM force will be retired over the next 10 years, a reduction that will only partly be offset by deployment of new road-mobile RS-24 Yars (SS-27 Mod 2) ICBMs such as this one near Teykovo northeast of Moscow.

Russia is planning to retire more than two-thirds of its current arsenal of nuclear land-based intercontinental ballistic missiles by the early 2020a. That includes some of the most iconic examples of the Soviet threat against the United States: SS-18 Satan, SS-19 Stiletto, and the world’s first road-mobile ICBM, the SS-25.

The plan coincides with the implementation of the New START treaty but significantly exceeds the reductions required by the treaty.

During the same period, Russia plans to deploy significant numbers of new missiles, but the production will not be sufficient to offset the retirement of old missiles. As a result, the size of Russia’s ICBM force is likely to decline over the next decade – with or without a new nuclear arms control treaty.

This and much more is described in our latest Nuclear Notebook published in the Bulletin of the Atomic Scientists.

New START aggregate numbers have been published by the United States and Russia.

.
By Hans M. Kristensen

The latest New START treaty aggregate numbers of strategic arms, which was quietly released by the State Department earlier last week, shows modest reductions and important changes in U.S. and Russian strategic nuclear forces.

Most surprisingly, the data shows that Russia has increased its number of deployed strategic nuclear warheads and is now again above the New START limit.

Because of the limited format of the released aggregate numbers, however, the changes are not explained or apparent. As a result, though not yet one year old, the New START treaty is already beginning to increase uncertainty about the status of U.S. and Russian nuclear forces. Continue reading »

July 31^st is the 20-year anniversary of signing of the Strategic Arms Reduction Treaty (START) between the United States and the Soviet Union. The treaty, also known as START I, marked the beginning of a treaty-based reduction of U.S. and Soviet (later Russian) strategic nuclear forces after the end of the Cold War.

START I required each country to limit its number of accountable strategic delivery vehicles (ballistic missiles and long-range bombers) to no more than 1,600 with no more than 6,000 accountable warheads. The treaty came with a unique on-site inspection regime where inspectors from the two countries would inspect each other’s declared force levels. Thousands of other warheads were not affected and the treaty did not require destruction of a single nuclear warhead. START I entered into effect on December 5^th, 2001, and expired on December 4, 2009.

Twenty years after the signing of START I, the United States and Russia are still in the drawdown phase of their strategic nuclear forces: START II followed in 1993, limiting the force levels to 3,500 accountable warheads by 2007 with no multiple warheads on land-based missiles; START II was never ratified by the U.S. Senate but surpassed by the Moscow Treaty in 2002, limiting the number of operationally deployed strategic warheads to 2,200 by 2012; The Moscow Treaty was replaced by the New START treaty signed in 2010, which limits the number of accountable strategic warheads to 1,550 on 700 deployed ballistic missiles and long-range bombers by 2018. Like its predecessors, New START does not limit thousands of non-deployed and non-strategic nuclear warheads and does not require destruction of a single warhead.

The Obama administration has stated that the next treaty must also place limits on non-deployed and non-strategic nuclear warheads.

You won’t be able to count SS-18s in the New START aggregate date.

Russia and the United States have released the first Fact Sheet with aggregate numbers for the strategic offensive nuclear forces counted under the New START treaty.

It shows that Russia has already dropped below the New START ceiling of 1,550 accountable deployed warheads and the United States is close behind, seven years before the treaty is scheduled to enter into effect (it makes you wonder what all the ratification delay was about).

But compared with the extensive aggregate numbers that were released during the previous START treaty, the new Fact Sheet is slim picking: just six numbers.

Unless the two countries agree to release more information in the months ahead, this could mark a significant step back in nuclear transparency. Continue reading »

Ambassador Brooks, Secretary Perry and Ambassador Matlock join FAS in call for continuing nuclear transparency under New START treaty

.By Hans M. Kristensen,

Three former U.S. officials have joined FAS in urging the United States and Russia to continue to declassify the same degree of information about their strategic nuclear forces under the New START treaty as they did during the now-expired START treaty.

The three former officials are: Linton Brooks, former chief U.S. START negotiator and administrator of the National Nuclear Security Administration, Jack Matlock, former U.S. ambassador to the Soviet Union and Special Assistant to President Ronald Reagan for national security affairs, and William Perry, former U.S. Secretary of Defense.

At issue is whether the United States and Russia will continue under the New START treaty to release to the public detailed lists – known as aggregate data – of their strategic nuclear forces with the same degree of transparency as they used to do under the now-expired START treaty. There has been concern that the two countries might reduce the information to only include numbers of delivery systems but withhold information about warhead numbers and locations.

In a joint letter, the three former officials joined FAS President Charles Ferguson and myself in urging the United States and Russia to “continue under the New START treaty the practice from the expired START treaty of releasing to the public aggregate numbers of delivery vehicles and warheads and locations.” This practice contributed greatly to international nuclear transparency, predictability, reassurance, and helped counter rumors and distrust, the letter concludes.

Both governments have stated their intention to seek to broaden the nuclear arms control process in the future to include other nuclear weapon states and the letter warns that achieving this will be a lot harder if the two largest nuclear weapon states were to decide to decrease transparency of their nuclear forces under New START.

“Any decrease in public release of information compared with START would be a step back.”

The letter was sent to Rose Gottemoeller, the U.S. Assistant Secretary of State for Arms Control, Verification and Compliance, and Sergey Kislyak, the Ambassador of the Russian Federation to the United States.

Russia has 3,700-5,400 nonstrategic nuclear weapons, including the old dual-capable AS-4 Kitchen air-launched missile seen here under the wings of a Tu-22 Backfire bomber at an unknown airbase. All Russian nonstrategic warheads are in central storage.   Image: web

The latest Nuclear Notebook in the Bulletin of the Atomic Scientists with our updated estimate of Russian nuclear forces is now available via Sage Publications: http://bos.sagepub.com/content/67/3/67.full.pdf+html.

We estimate that Russia currently has nearly 2,430 strategic warheads assigned to operational strategic missiles and bombers, although most of the bomber weapons are probably in central storage. Another 3,700-5,400 nonstrategic warheads are in central storage, of which an estimated 2,080 can be delivered by nonstrategic aircraft, naval vessels and short-range missiles. Another 3,000 warheads are thought to be awaiting dismantlement, for a total inventory of some 11,000 nuclear warheads.

Ten NATO countries recommend increasing transparency of non-strategic nuclear weapons, including numbers and locations at military facilities such as Incirlik Air Base in Turkey. Neither NATO nor Russia currently disclose such information.

Four NATO countries supported by six others have proposed a series of steps that NATO and Russia should take to increase transparency of U.S. and Russian non-strategic nuclear weapons.

The steps are included in a so-called “non-paper” that Germany, the Netherlands, Norway and Poland jointly submitted at the NATO Foreign Affairs Minister meeting in Berlin on 14 April.

Six other NATO allies – Belgium, the Czech Republic, Hungary, Iceland, Luxemburg and Slovenia – also supported the paper. Continue reading »

U.S. officials say that aggregate numbers of the New START treaty will be made publicly available but that these may be very general numbers and a decision still has to be made. For a copy of the final START aggregate numbers, click here.

The first data exchange of the New START treaty between the United States and Russia has taken place, according to a report by RIA Novosti.

This is the first of more than 20 such data exchanges planned under the treaty for the next 10 years where Russia and the United States twice a year will send each other a list showing how many long-range ballistic missiles and heavy bombers they have and how many nuclear weapons they carry.

But while the exchanges will increase U.S-Russia nuclear transparency, the rest of the world may be facing a future with less information about U.S. and Russian strategic nuclear forces than in the past.

“All exchanges are classified and will not be subject to release,” a U.S. official told me. “There may be some information on very general numbers under the Treaty that could be made public, but that is still to be determined, and will not occur for a least six months if it occurs at all.” Continue reading »
