India’s nuclear weapons “are not for warfighting,” the chief of India’s army said Sunday at the Army Day Parade. The weapons have “a strategic capability and that is where it should end,” General V. K. Singh declared.

The rejection of nuclear warfighting ideas is a welcoming development in the debate over the role of nuclear weapons in South Asia. Pakistan’s military’s description of its new snort-range NASR missile as a “shoot and scoot…quick response system” has rightly raised concerns about the potential early use of nuclear weapons in a conflict.

NASR is one of several new nuclear weapon systems that are nearing deployment with warheads from a Pakistani stockpile that has nearly doubled since 2005.

India is also increasing its arsenal and already has short-range missiles with nuclear capability: the land-based Prithvi has been in operation for a decade, and a naval version (Dhanush) is under development. But India’s posture seems focused on getting its medium-range Agni II in operation, developing longer-range versions to target China, and building a limited submarine-based nuclear capability.

If Gen. Singh’s rejection of nuclear warfighting is reflected in India’s future nuclear posture, two important things will have been achieved: rejection of the mindless tit-for-tat philosophy that otherwise dominates nuclear posturing; and limiting the scenarios where nuclear weapons otherwise could come into use. The rejection also has importance for other nuclear weapon states, where some have called for making nuclear weapons more “tailored” to limited regional scenarios.

The discovery and subsequent killing of Osama bin Laden in Abbottabad, Pakistan raises troubling questions. The success of the U.S.’s airborne raid on bin Laden’s compound-undetected by Pakistan’s radar- lends credence to the belief that terrorists might be capable of successfully seizing Pakistan’s nuclear weapons.

Mr. Charles P. Blair has authored a new FAS report (PDF) that addresses the security gap and identifies specific terrorists within Pakistan who are motivated and potentially capable of taking Pakistani nuclear assets. Blair explains in the report details why, amid Pakistan’s burgeoning civil war, the Pakistani Neo-Taliban is the most worrisome terrorist group motivated and possibly capable of acquiring nuclear weapons.

The latest Nuclear Notebook on Pakistan’s nuclear forces is available on the Bulletin of the Atomic Scientists web site. Since our previous Notebook on Pakistan in 2009 there have been several important developments.

Based on our own estimates, official statements, and fissile material production estimates produced by the International Panel of Fissile Materials, we conclude that Pakistan’s current nuclear weapons stockpile of 90-110 warheads might increase to 150-200 within the next decade. This would bring the Pakistani stockpile within range of the British stockpile, the smallest of the original five nuclear weapon states, but still far from that of France (despite some recent news reports to the contrary).

This development is precipitated by the anticipated introduction of several new nuclear delivery systems over the next years, including cruise missiles and short-range ballistic missiles. The capabilities of these new systems will significantly change the composition and nature of Pakistan’s nuclear posture.

India is following this development closely and is also modernizing its nuclear arsenal and fissile material production capability. The growing size, diversity, and capabilities of the Pakistani and Indian nuclear postures challenge their pledge to only acquire a minimum deterrent. Bilateral arms control talks and international pressure are urgently needed to halt what is already the world’s fastest growing nuclear arms race.

Andrew Bast at Newsweek was kind enough to use our estimates for world nuclear forces in his latest article on Pakistan growing arsenal.

Of special interest is Pakistan’s production of the NASR (Hatf-9), a worrisome development for South Asia and the decade-long efforts to avoid nuclear weapons being used. With its range of only 60 kilometers, the multi-tube NASR system is not intended to retaliate against Indian cities but be used first against advancing Indian army forces in a battlefield scenario.

Pakistan’s military’s Inter Services Public Relations (ISPR) describes NASR as a system that “carries nuclear warheads of appropriate yield with high accuracy, shoot and scoot attributes” developed as a “quick response system” to “add deterrence value” to Pakistan’s strategic weapons development program “at shorter ranges” in order “to deter evolving threats.”

“Shoot and scoot…quick response system” ??

That sounds like an echo from nuclear battlefields in Europe at the height of the Cold War. It is time for Pakistan to explain how many nuclear weapons, of what kind, and for what purpose are needed for its minimum deterrent.

As bad as it is, though, talk about Pakistan’s nuclear arsenal passing the size of France at some point is, at the current rate, probably one or two decades ahead.

Don’t forget: Pakistan’s nuclear arsenal is not equal to the number of warheads that could potentially be produced by all the highly-enriched uranium and plutonium Pakistan might have produced. The size also depends on other factors such as the number of delivery vehicles and other limitations.

India-Pakistan nuclear competition on display again

.
By Hans M. Kristensen

If Indian news reports (here, here, and here) are any indication, India has once again discovered that Pakistan might possess a few nuclear weapons more than India.

This time the reports are based on an article Robert Norris and I published in the Bulletin of the Atomic Scientists, in which we provide estimates for the number of nuclear weapons in the world.

In 2009, our report on Pakistan’s nuclear forces triggered a statement from the chief of the Indian army that if the warhead estimate in our report was correct then Pakistan had moved beyond what is needed for deterrence. The unintended acknowledgement: so had India.

In 2008, reports about the arrival of the first Chinese Jin-class SSBN at a naval base on Hainan Island were followed by suggestions that India needed to build perhaps five new Arihant-class ballistic missile submarines.

As far as I can gauge, apart from nuclear testing where India started first, Pakistan has always been a little ahead in warheads, fissile material, and delivery systems. But neither country can claim any nuclear moral high ground; both are increasing their nuclear arsenals, both are producing more fissile material for nuclear weapons, and both are diversifying the means to deliver nuclear weapons and extending their range.

The two countries are now at a warhead level about equal to that of Israel (~80 warheads). But whereas it took Israel 40 years to reach that level, India and Pakistan have done so in only 12 years. And they’re apparently not done.

Although neither government wants to say so publicly, India and Pakistan are in effect in a nuclear arms race. It might not be of the intensity of the Cold War arms race between the Soviet Union and the United States, but it is a race nonetheless for capability and systems. Pointing to the other side having more only underscores that dynamic.

Indian and Pakistani security will probably be served better by trying soon to define just how big a nuclear force is sufficient for minimum deterrence so that “prudent planning” doesn’t take them to a new and more dangerous level.

Estimated Locations of Nuclear Weapons, 2009

Some 23,300 nuclear weapons are stored at 111 locations around the world

.The world’s approximately 23,300 nuclear weapons are stored at an estimated 111 locations in 14 countries, according to an overview produced by FAS and NRDC.

Nearly half of the weapons are operationally deployed with delivery systems capable of launching on short notice.

The overview is published in the Bulletin of the Atomic Scientists and includes the July 2009 START memorandum of understanding data. A previous version was included in the annual report from the International Panel of Fissile Materials published last month.

Saratov Nuclear Sites

More than 1,000 nuclear weapons surround Saratov.

Russia has an estimated 48 permanent nuclear weapon storage sites, of which more than half are on bases for operational forces. There are approximately 19 storage sites, of which about half are national-level storage facilities.  In addition, a significant number of temporary storage sites occasionally store nuclear weapons in transit between facilities.

This is a significant consolidation from the estimated 90 Russian sites ten years ago, and more than 500 sites before 1991.

Many of the Russian sites are in close proximity to each other and large populated areas.  One example is the Saratov area where the city is surrounded by a missile division, a strategic bomber base, and a national-level storage site with probably well over 1,000 nuclear warheads combined (Figure 2).

The United States stores its nuclear weapons at 21 locations in 13 states and five European countries.  This is a consolidation from the estimated 24 sites ten year ago, 50 at the end of the Cold War, and 164 in 1985 (see Figure 3).

B61 Nuclear Bombs in Storage

Approximately 50 B61 nuclear bombs inside an igloo at what might be Nellis Air Force Base in Nevada. Seventy-five igloos at Nellis store “one of the largest stockpile in the free world,” according to the U.S. Air Force, one of four central storage sites in the United States.

Europe has about the same number of nuclear weapon storage locations as the Continental United States, with weapons scattered across seven countries. This includes seven sites in France and four in Britain. Five non-nuclear NATO countries (Belgium, Germany, Italy, the Netherlands, and Turkey) still host U.S. nuclear weapons first deployed there during the Cold War.

We estimate that China has 8-14 facilities associated with nuclear weapons, most likely closer to the lower number, near bases with units that operate nuclear missiles or aircraft.  None of the weapons are believed to be fully operational but stored separate from delivery vehicles at sites controlled by the Central Military Commission.

Is There a Nuclear Weapons Storage Site on Hainan Island?

Where does China store nuclear warheads for its ballistic missile submarines?  The naval base near Julin on Hainan Island has extensive underground facilities.  An alternative to the base itself could potentially be a facility elsewhere on the island, such as Foluo Air Base where construction of an underground facility began five years before the first SSBN arrived at Hainan. Or are the weapons stored on the mainland?  Click image to enlarge.

Israel probably has about four nuclear sites, whereas the nuclear storage facilities in India and Pakistan are – despite many rumors – largely undetermined.  All three countries are thought to store warheads separate from delivery vehicles.

Despite two nuclear tests and many rumors, we are unaware of publicly available evidence that North Korea has operationalized its nuclear weapons capability.

Warhead concentrations vary greatly from country to country. With 13,000 warheads at 48 sites, Russian stores an average of 270 warheads at each location. The U.S. concentration is much higher with an average of 450 warheads at each location. These are averages, however, and in reality the distribution is thought to be much more uneven with some sites only storing tens of warheads.

Finally, a word of caution is in order: estimates such as these obviously come with a great deal of uncertainty, as we don’t have access to classified intelligence estimates. Based on publicly available information and our own assumptions we have nonetheless produced a best estimate that we hope will assist the public debate. Comments and suggestions are encouraged so we can adjust the overview in the future.

By Hans M. Kristensen

Pakistan’s nuclear weapons stockpile now includes an estimated 70-90 nuclear warheads, according to the latest Nuclear Notebook published in the Bulletin of the Atomic Scientists. The estimate is an increase compared with the previous estimate of approximately 60 warheads due to Pakistan’s pending introduction of a new ballistic missile and cruise missiles.

The increase in the warhead estimate does not mean Pakistan is thought to be sprinting ahead of India, which is also increasing its stockpile.

Modernizations

The nuclear-capable Shaheen-II medium-range ballistic missile appears to be approaching operational deployment after long preparation. The Army test-launched two missiles within three days in April 2008, and the U.S. Air Force National Air and Space Intelligence Center (NASIC) reported in June 2009 that the weapon “probably will soon be deployed.”

Two types of nuclear-capable cruise missiles are also under development; the ground-launched Barbur and the air-launched Ra-ad. The development of cruise missiles with nuclear capability is interesting because it suggests that Pakistan’s nuclear weapons designers have been successful in building smaller and lighter plutonium warheads.

Warhead Security Concerns

An article published in the July issue of the CTC Sentinel news letter of the Combating Terrorism Center at the U.S. Military Academy at West Point gained widespread attention for describing terrorist attacks against three of Pakistan’s rumored nuclear weapons facilities: Wah Ordnance Facility, Kamra Air Base, and Sargodha Weapons Storage Facility. Although the incidents had been reported before, the article triggered the predictable rejection from a Pakistani military spokesman but with the additional claim that neither facility stored nuclear weapons. “These are nowhere close to any nuclear facility,” he said. Yet the official would most likely not disclose the location of the nuclear weapons, even if he knew where they were.

While the CTC Sentinel article says “most” of Pakistan’s nuclear sites might be close to or even within terrorist dominated areas, senior U.S. officials said the weapons were secure and mostly located south of Islamabad.

Regardless of the actual location of the weapons, there have, of course, been many more terrorists attacks against other facilities that have nothing to do with Pakistan’s nuclear weapons program, and so far no pattern has emerged in public of a concerted terrorist effort against nuclear sites – much less an attempt to steel nuclear weapons. A U.S. intelligence official commented to the New York Times that it was unclear whether the attackers knew what the facilities contained. “If they were after something specific, or were truly seeking entry, you’d think they might use a different tactic, one that’s been employed elsewhere – such as a bomb followed by a small-arms assault.”

Pakistani and U.S. statements about the Pakistani nuclear arsenal, and the basis for our estimate, are included in the Nuclear Notebook.

Publication: Pakistani Nuclear Forces, 2009

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.

Chinese Nuclear Forces

As the DF-3A retirement continues (there are now only 5-10 launchers left of close to 100 in the 1980s), the liquid-fuel missile is being replaced by a family of solid-fuel DF-21 variants. The NASIC identifies four, including two nuclear versions (Mod 1 and Mod 2), one conventional version, and an anti-ship version that unlike the others is not yet deployed.

Thankfully, the report dispels widespread speculation by web sites, news media, and even Jane’s after images began circulating on the Internet, that a DF-25 had been deployed, some even said with three nuclear warheads.  But it was, as I predicted last year and NASIC now confirms, in fact a DF-21.

DF-21 Road-Mobile Launchers

A column of DF-21s on the road in what could be the Delingha deployment are in Qinghai Province. Several of the vehicles have identical camouflage patterns, raising suspicion that the image has been manipulated. Four DF-21 versions exist, two nuclear, one conventional, and one anti-ship version.                                                                                       Image: Web

.
The report also reaffirms that the first of the DF-31s and DF-31As “have been deployed to units within the Second Artillery Corps,” and NASIC estimates that “less than 15” are deployed, up from the “less than 10” estimate in the Pentagon’s March 2009 report (which actually used 2008 data).

The NASIC report states that neither of China’s two types submarine-launched ballistic missiles is operational. This suggests that the multi-year overhaul of the JL-1 equipped Xia SSBN, which was completed last year, was not successful. The successor missile JL-2 for the new Jin-class SSBNs has not reached operational status either. NASIC gives the JL-2 the U.S. designation CSS-NX-14, not a numerical follow-on to the JL-1, which is listed as CSS-NX-3. The “14” could be a typo, but it appears several places in the report. The JL-2 is shown to have roughly the same dimensions as the Russian SS-N-32 SLBM.

NASIC lists single warheads on all of the Chinese missiles, not multiple warheads as speculated by many. “China could develop MIRV payloads for some of its ICBMs,” the report states. Yet it also predicts that, “Future ICBMs probably will include some with multiple independently-targetable reentry vehicles.” Whether that prediction – which appears to hint that China has more ICBMs under development – comes true remains to be seen, and the U.S. intelligence community has stated for years that one development that could trigger it is a U.S. ballistic missile defense system.

The report echoes recent statements from other branches of the U.S. intelligence community that the number of warheads on Chinese ICBM capable of reaching the United States could expand to “well over 100 in the next 15 years.” Unfortunately, “well over 100” can mean anything so it is hard to compare this NASIC’s projection with the CIA projection from 2001 of 75-100 warheads “primarily targeted against the United States” by 2015. That projection only included DF-5A and DF-31A capable of targeting all of the United States, with the high number requiring multiple warheads on DF-5A. But the timeline for the anticipated increase has slipped considerably from 2015 to 2024.

U.S. Projections for Chinese ICBM Nuclear Warheads

Projections by the U.S. intelligence community for when China’s long-range nuclear arsenal will double continues to slide. Click image to download larger version.

.

Moreover, ICBMs “primarily targeted against the United States” is a smaller group of missiles than those “capable of reaching the United States,” which currently includes about 60 DF-4, DF-5A, DF-31 and DF-31A ICBMs with as many warheads. For this group to grow to “well over 100 warheads” suggests that NASIC anticipates that China will deploy at least 60-70 DF-31, DF-31A and JL-2 missiles by 2024 (the DF-4 will probably have been retired by then). Assuming that includes 36 JL-2s on three Jin-class SSBNs, an additional 20-30 total DF-31s and DF-31As would have to be deployed to reach 120 ICBM warheads. If five SSBNs were deployed, then only 10 additional land-based ICBMs would be required, or 30 if the 20 DF-5As were retired.

The DH-10 land-attack cruise missile is listed as “conventional or nuclear,” the same designation used for the nuclear and conventional Russian AS-4. But unlike the 2009 DOD report on Chinese military forces, which lists 150-350 DH-10s deployed with 40-50 launchers, NASIC lists the operational status as “undetermined.”

Russian Nuclear Forces

NASIC states that “Russia retains about 2,000 warheads on ICBMs,” which is far too many for the land-based ICBM force and so probably includes SLBMs as well. The ICBM force will continue to decrease due to arms control agreements, aging missiles, and resource constraints. Even so, “Russia will probably retain the largest ICBM force outside the United States,” and “most of these missiles are maintained on alert, capable of being launched within minutes of receiving a launch order,” according to NASIC.

The multiple-warhead RS-24 ICBM is, according to NASIC, not a new missile but a modified version of the SS-27 (Topol-M).

The NASIC report formally designates the “multiple” warhead RS-24 ICBM to be a modification of the SS-27 Mod 1. This has some significance because Russia under START is not allowed to increase the warhead loading on missiles declared under the treaty, but in anticipation of the treaty expiring in December 2009 apparently has been working on doing so anyway. The RS-24, which will exist in both silo and road-mobile versions, is not yet deployed but Russian military officials have said this will happen in December.

On the submarine force the modified SS-N-23 known as Sineva is listed as carrying the same number of warheads (4) as the original version, far less than the “up to 10” listed by NASIC in 2006 and by Russian news media. The range is listed as the usual 8,000+ km even though the Russian Navy claimed in October 2008 to have test-flown the missile to 11,547 km. NASIC also continues to list two remaining Typhoon-class SSBNs as capable of carrying the SS-N-20, even though the missile is reported to have been withdrawn from service. I suspect this is because the report uses START-counted missile tubes. A third Typhoon SSBN has been converted as a test platform for the SS-N-32/Bulava-30, and NASIC lists this submarine with 20 tubes for the new missile.

Interestingly, the kh-102 cruise missile, a replacement for the AS-15 long rumored to be under development, is not listed by NASIC.

Indian Nuclear Forces

Even though Indian news media reports and private/corporate institutes have reported for years that Agni I and Agni II were deployed, the NASIC report shows that operational deployment of the road-mobile Agni I SRBM has only recently begun, with “fewer than 25” missile launchers deployed. NASIC seems to back our assessment from last year that the Agni II at that time was not yet fully operational, by listing “fewer than 10” launchers deployed.

Two short-range sea-based ballistic missiles are under development: Dhanush and Sagarika. Neither is operational yet, and NASIC safely estimates that the Sagarika will become operational sometime after 2010.

Despite Indian news media reports of development of a nuclear-capable cruise missile, no mentioning of such a weapon system is made by NASIC.

Pakistani Nuclear Forces

There are fewer than 50 launchers for the road-mobile Ghaznavi and Shaheen I SRBMs listed in the NASIC report, and the 2,000+ km Shaheen II MRBM is not yet operational but may be soon. Pakistan also appears to have two nuclear-capable cruise missiles under development: the ground-launched Babur and the air-launched Ra’ad.

Other Nuclear Weapon States

Although “friendly” nuclear weapon states are not included because they are not a “threat” to the United States, the report’s section on cruise missiles is nonetheless interesting because it – unlike the ballistic missile sections – describes weapon systems of “friendly” nuclear weapon states such as France and Israel. Yet nuclear systems, such as the French ASMP-A, are excluded. Israeli submarine-based cruise missiles, which have been rumored to have nuclear capability (I’m not convinced), are not included either.

Curiously, even after two nuclear tests and the intelligence community stating for more than a decade that North Korea has nuclear weapons, the NASIC report does not list any of North Korea’s weapons as “nuclear” or “conventional or nuclear.” That is, I think, interesting.

Pakistan’s nuclear weapons are “widely dispersed” says Secretary of State Hillary Clinton. Does that include the large weapons storage complex at Sargodha? Click for image.

By Hans M. Kristensen

Secretary of State Hillary Clinton has expressed concern over the safety of Pakistan’s nuclear weapons in the light of increasing violence in the country. The weapons “are widely dispersed in the country – they are not at a central location,” she said in what is perhaps the first U.S. public indication of its knowledge about how Pakistan stores its nuclear weapons.

We’re pleased that both Washington Times and the Carnegie Endowment use our estimates for how many nuclear weapons Pakistan and other countries have. For additional information about Pakistan’s nuclear forces, see:

New low-yield nuclear warheads for cruise missiles on Russia’s submarines?.

.
By Hans M. Kristensen

Two recent news reports have drawn the attention to Russia’s tactical nuclear weapons. Earlier this week, RIA Novosti quoted Vice Admiral Oleg Burtsev, deputy head of the Russian Navy General Staff, saying that the role of tactical nuclear weapons on submarines “will play a key role in the future,” that their range and precision are gradually increasing, and that Russia “can install low-yield warheads on existing cruise missiles” with high-yield warheads.

This morning an editorial in the New York Times advocated withdrawing the “200 to 300” U.S. tactical nuclear bombs deployed in Europe “to make it much easier to challenge Russia to reduce its stockpile of at least 3,000 short-range weapons.”

Both reports compel – each in their own way – the Obama administration to address the issue of tactical nuclear weapons.

The Russian Inventory

Like the United States, Russia doesn’t say much about the status of its tactical nuclear weapons. The little we have to go by is based on what the Soviet Union used to have and how much Russian officials have said they have cut since then.

Unofficial estimates set the Soviet inventory of tactical nuclear weapons at roughly 15,000 in mid-1991. In response to unilateral cuts announced by the United States in late 1991 and early 1992, Russian President Boris Yeltsin pledged in 1992 that production of warheads for ground-launched tactical missiles, artillery shells, and mines had stopped and that all such warheads would be eliminated. He also pledged that Russia would dispose of half of all airborne and surface-to-air warheads, as well as one-third of all naval warheads.

In 2004, the Russian Foreign Ministry stated that “more than 50 percent” of these warhead types have been “liquidated.” And in September 2007, Defense Ministry official Colonel-General Vladimir Verkhovtsev gave a status report of these reductions that appeared to go beyond President Yeltsin’s pledge.

Based on this, Robert Norris and I make the following cautious estimate (to be published in the Bulletin of the Atomic Scientists in late April) of the current Russian inventory of tactical nuclear weapons:

Estimate from forthcoming Nuclear Notebook in the Bulletin of the Atomic Scientists.

.
Based on the number of available nuclear-capable delivery platforms, we estimate that nearly two-thirds of these warheads are in reserve or awaiting dismantlement. The remaining approximately 2,080 warheads are operational for delivery by anti-ballistic missiles, air-defence missiles, tactical aircraft, and naval cruise missiles, depth bombs, and torpedoes. The Navy’s tactical nuclear weapons are not deployed at sea under normal circumstances but stored on land.

The Other Nuclear Powers

The United States retains a small inventory of perhaps 500 active tactical nuclear weapons. This includes an estimated 400 bombs (including 200 in Europe) and 100 Tomahawk cruise missiles (all on land). Others, perhaps 700, are in inactive storage.

France also has 60 tactical-range cruise missiles, including some on its aircraft carrier, although it calls them strategic weapons.

The United Kingdom has completely eliminated its tactical nuclear weapons, although it said until a couple of years ago that some of its strategic Trident missiles had a “sub-strategic” mission.

Information about possible Chinese tactical nuclear weapons is vague and contradictory, but might include some gravity bombs.

India, Pakistan, and Israel have some nuclear weapons that could be considered tactical (gravity bombs for fighter-bombers and, in the case of India and Pakistan, short-range ballistic missiles), but all are normally considered strategic.

Russian Nuclear-Capable Cruise Missile Launch

A nuclear-capable SS-N-19 Shipwreck cruise missile is launched from a Kirov-class nuclear-powered guided missile cruiser. The ship is equipped with 20 launchers for the SS-N-19 missile, which can carry a 500-kiloton warhead. Other tactical nuclear weapon systems include the SS-N-16 anti-submarine rocket, and the SA-N-6 anti-air missile.

.
Implications and Issues

Whether Vice Admiral Burtsev’s statement is more than boasting remains to be seen, but it is a timely reminder to the Obama administration of the need to develop a plan for how to tackle the tactical nuclear weapons.

Russia’s nuclear posture is now approaching a situation where there are more tactical nuclear weapons in the inventory than strategic weapons. And NATO’s remnant of the Cold War tactical nuclear posture in Europe seems stuck in the mud of nuclear dogma and bureaucratic inaction.

None of these tactical nuclear weapons are limited or monitored by any arms control agreements, and – for all the worries about terrorists stealing nuclear weapons – are the most easy to run away with.

In April, NATO is widely expected to kick off a (long-overdue) review of its Strategic Concept from 1999. It would be a mistake to leave the initiative on what to do with the tactical nuclear weapons to the NATO bureaucrats. The vision must come from the top and President Obama needs to articulate what it is soon.

A new Congressional Research Service report on “U.S. Arms Sales to Pakistan” recently obtained by the FAS provides a succinct overview of recent U.S. arms sales to General Pervez Musharraf’s regime, the tumultous fifty-year history of US security assistance to Pakistan, and presidential authority to stop such sales. The release of the report coincides with a worsening political crisis in Pakistan and growing Congressional and public discontent over the United States’ multi-billion dollar military aid program for General Musharraf’s beseiged and increasingly authoritarian regime.

Shaheen 2 launch

By Hans M. Kristensen

Pakistan is preparing its next-generation of nuclear-capable ballistic missile for deployment. A satellite image taken on June 5, 2005, shows what appears to be 15 Transporter Erector Launchers (TELs) for the medium-range Shaheen 2 fitting out at the National Defense Complex near Fatehjang approximately 30 kilometers southwest of Islamabad.

The vehicles were discovered as part of preparations for the latest Nuclear Notebook on Pakistani nuclear forces published in the May/June issue of the Bulletin of the Atomic Scientists. The Notebook is written by Hans M. Kristensen of the Federation of American Scientists and Robert S. Norris of the Natural Resources Defense Council.

The authors estimate that Pakistan currently has an arsenal of about 60 nuclear weapons. In the last five and a half years, Pakistan has deployed two new nuclear-capable ballistic missiles, entered the final development stages of a potentially nuclear-capable cruise missile, started construction of a new plutonium production reactor, and is close to completing a second chemical separation facility. As Pakistan completes development of two more nuclear-cable ballistic missiles and a cruise missile in the next few years, the nuclear arsenal will increase further.

Pakistani government responds to blog:The government downplayed a report by an organization of American scientists that Pakistan is preparing its next generation nuclear-capable ballistic missile for deployment. “This is a speculative report which contains part fact and part fiction,” is how the spokesperson characterized the report.”Source: Dawn, “N-Capable Missiles,” May 11, 2007.

The main driver for Pakistan’s nuclear modernization appears to be India’s nuclear build-up, although national prestige probably also is a factor. The two countries appear to be entering a new phase in their regional nuclear arms race with medium-range ballistic missiles gradually replacing aircraft as the backbone of their nuclear strike forces. In contrast to aircraft, ballistic missiles have a very short flight time and cannot be recalled once launched.
