The U.S. Air Force National Air and Space Intelligence Center (NASIC) has published its long-awaited update to the Ballistic and Cruise Missile Threat report, one of the few remaining public (yet sanitized) U.S. intelligence assessment of the world nuclear (and other) forces.

Previous years’ reports have been reviewed and made available by FAS (here, here, and here), and the new update contains several important developments – and some surprises.

Most important to the immediate debate about further U.S.-Russian reductions of nuclear forces, the new report provides an almost direct rebuttal of recent allegations that Russia is violating the INF Treaty by developing an Intermediate-range ballistic missile: “Neither Russia nor the United States produce or retain any MRBM or IRBM systems because they are banned by the Intermediate-Range Nuclear Force Treaty, which entered into force in 1988.”

Another new development is a significant number of new conventional short-range ballistic missiles being deployed or developed by China.

Finally, several of the nuclear weapons systems listed in a recent U.S. Air Force Global Strike Command briefing are not included in the NASIC report at all. This casts doubt on the credibility of the AFGSC briefing and creates confusion about what the U.S. Intelligence Community has actually concluded.

Russia

The report estimates that Russia retains about 1,200 nuclear warheads deployed on ICBMs, slightly higher than our estimate of 1,050. That is probably a little high because it would imply that the SSBN force only carries about 220 warheads instead of the 440, or so, warheads we estimate are on the submarines.

“Most” of the ICBMs “are maintained on alert, capable of being launched within minutes of receiving a launch order,” the report states. This excessive alert posture is similar to that of the United States, which has essentially all of its ICBMs on alert.

The report also confirms that although Russia is developing and deploying new missiles, “the size of the Russia missile force is shrinking due to arms control limitations and resource constraints.”

Unfortunately, the report does not clear up the mystery of how many warheads the SS-27 Mod 2 (RS-24, Yars) missile carries. Initially we estimated thee because the throw-weight is similar to the U.S. Minuteman III ICBM. Then we considered six, but have recently settled on four, as the Strategic Rocket Forces commander has stated.

The report states that “Russia tested a new type of ICBM in 2012,” but it undercuts rumors that it not an ICBM by listing its range as 5,500+ kilometers. Moreover, in an almost direct rebuttal of recent allegations that Russia is violating the INF Treaty by developing an Intermediate-range ballistic missile, the report concludes: “Neither Russia nor the United States produce or retain any MRBM or IRBM systems because they are banned by the Intermediate-Range Nuclear Force Treaty, which entered into force in 1988.”

The report also describes how Russian designers are working to modify missiles to overcome U.S. ballistic missile defense systems. The SS-27 Mod 1 (Topol-M) deployed in silos at Tatishchevo was designed with countermeasures to ballistic missile systems, and Russian officials claim that a new class of hypersonic vehicle is being developed to overcome ballistic missile defense systems, according to NASIC.

The report also refers to Russian press report that a rail-mobile ICBM is being considered, and that a new “heavy” ICBM is under development.

One of the surprises in the report is that SS-N-32/Bulava-30 missile on the first Borei-class SSBN is not yet considered fully operational – at least not by NASIC. The report lists the missile as in development and “not yet deployed.”

Another interesting status is that while the AS-4 and AS-15 nuclear-capable air-launched cruise missiles are listed as operational, the new Kh-102 nuclear cruise missile that Russian officials have said they’re introducing is not listed at all. The Kh-102 was also listed as already “fielded” by a recent U.S. Air Force Global Strike Command briefing.

Finally, while the report lists the SS-N-21 sea-launched cruise missile as operational, it does not mention the new Kalibr cruise missile for the Yasen-class attack submarine that U.S. Air Force Global Strike Command recently listed a having been “fielded” within the past five years.

China

The NASIC report states that the Chinese ballistic missile force is expanding both in size and types of missiles.

Deployment of the DF-31A (CSS-10 Mod 2) ICBM continues at a slow pace with “more than 15” launchers deployed six years after the system was first introduced.

Despite many rumors about a new DF-41 ICBM, the NASIC report does not mention this system at all.

Deployment of the shorter-range DF-31 (CSS-10 Mod 1) ICBM, on the contrary, appears to have stalled or paused, with only 5-10 launchers deployed seven years after it was initially introduced (see my recent analysis of this trend here). Moreover, the range of the DF-31 is lowered a bit, from 7,200+ km in the 2009 report to 7,000+ in the new version.

Medium-range nuclear missiles include the DF-21 (CSS-5) (in two versions: Mod 1 and Mod 2, but with identical range etc.) and the old DF-3A (CSS-2), which is still listed as deployed. Only 5-10 launchers are left, probably in a single brigade that will probably convert to DF-21 in the near future.

An important new development concerns conventional missiles, where the NASIC report states that several new systems have been introduced or are in development. This includes a “number of new mobile, conventionally armed MRBMs,” apparently in addition to the DF-21C and DF-21D already known. As for the DF-21D anti-ship missile, report states that “China has likely started to deploy” the missile but that it is “unknown” how many are deployed.

More dramatic is the development on five new short-range ballistic missiles, including the CSS-9, CSS-11, CSS-14, CSS-X-15, and CSS-X-16. The CSS-9 and CSS-14 come in different versions with different ranges. The CSS-11 Mod 1 is a modification of the existing DF-11, but with a range of over 800 kilometers (500 miles). None of these systems are listed as nuclear-capable.

Concerning sea-based nuclear forces, the NASIC report echoes the DOD report by saying that the JL-2 SLBM for the new Jin-class SSBN is not yet operational. The JL-2 is designated as CSS-NX-14, which I thought it was a typo in the 2009 report, as opposed to the CSS-NX-3 for the JL-1 (which is also not operational).

NASIC concludes that JL-2 “will, for the first time, allow Chinese SSBNs to target portions of the United States from operating areas located near the Chinese coast.” That is true for Guam and Alaska, but not for Hawaii and the continental United States. Moreover, like the DF-31, the JL-2 range estimate is lowered from 7,200+ km in the 2009 report to 7,000+ km in the new version. Earlier intelligence estimates had the range as high as 8,000+ km.

One of the surprises (perhaps) in the new report is that it does not list the CJ-20 air-launched cruise missile, which was listed in the U.S. Air Force Global Strike Command briefing as a nuclear cruise missile that had been “fielded” within the past five years.

Concerning the overall size of the Chinese nuclear arsenal, there have been many rumors that it includes hundreds or even thousands of additional warheads more than the 250 we estimate. STRATCOM commander has also rejected these rumors. To that end, the NASIC report lists all Chinese nuclear missiles with one warhead each, despite widespread rumors in the news media and among some analysts that multiple warheads are deployed on some missiles.

Yet the report does echo a projection made by the annual DOD report, that “China may also be developing a new road-mobile ICBM capable of carrying a MIRV payload.” But NASIC does not confirm widespread news media rumors that this system is the DF-41 – in fact, the report doesn’t even mention the DF-41 as in development.

As for the future, the NASIC report repeats the often-heard prediction that “the number of warheads on Chinese ICBMs capable of threatening the United States is expected to grow to well over 100 in the next 15 years.” This projection has continued to slip and NASIC slips it a bit further into the future to 2028.

Pakistan

Most of the information about the Pakistani system pretty much fits what we have been reporting. The only real surprise is that the Shaheen-II MRBM does still not appear to be fully deployed, even though the system has been flight tested six times since 2010. The report states that “this missile system probably will soon be deployed.”

India

The information on India also fits pretty well with what we have been reporting. For example, the report refers to the Indian government saying the Agni II IRBM has finally been deployed. But NASIC only lists “fewer than 10” Agni II launchers deployed, the first time I have seen a specific reference to how many of this system are deployed. The Agni III IRBM is said to be ready for deployment, but not yet deployed.

North Korea

The NASIC report lists the Hwasong-13 (KN-08), North Korea’s new mobile ICBM, but confirms that the missile has not yet been flight tested. It also lists an IRBM, but without naming it the Musudan.

The mysterious KN-09 coastal-defense cruise missile that U.S. Air Force Global Strike Command recently listed as a new nuclear system expected within the next five years is not mentioned in the NASIC report.
