It’s relatively easy to observe Russian missile bases from above. It’s much harder to do it from inside.
But in September, the Russian Ministry of Defense released a rare video of a command exercise which features mobile SS-27 Mod 2 “Yars-S” ICBMs driving around their base near Novosibirsk.
The base itself, which is likely to be the temporary home of the 382nd Guards Missile Regiment, has a relatively strange layout, which makes it significantly easier to identify. Unlike other Yars bases in the 39th Guards Missile Division (which houses the 382nd Regiment)––or even across the region––this base does not have any vehicle garages. Instead, the Yars launchers and support vehicles are simply parked out in the open, usually under camouflage (although they occasionally mix up their camouflage, weirdly replacing the forest green with snowy white well before any snow actually touches the ground!).
The September video shows Russian troops uncovering their ICBMs, taking them out for a spin, and eventually tucking them back in under camouflage blankets.
This regiment––along with the other two Novosibirsk bases associated with the 39th Guards Missile Division––recently completed its long-awaited conversion to Yars ICBMs from its older SS-25 Topol ICBMs. These new missiles are clearly visible in both satellite imagery and in the Ministry of Defense video.
During its conversion, the regiment was moved from its previous base (55°19’2.72”N, 83°10’6.70”E) to this temporary location, while the old base was dismantled in preparation for a substantial upgrade to build new missile shelters for the Yars ICBMs, as well as service and administrative buildings. Construction stalled for several years, possibly because of budget cuts, but has recently picked up again. Once completed, the 382nd Guards Missile Regiment presumably will be relocated back to its old base.
As we write in the Nuclear Notebook, Russia continues to retire its SS-25s at a rate of one or two regiments (nine to 18 missiles) each year, replacing them with newer Yars ICBMs. It is unclear how many SS-25s remain in the active missile force; however, we estimate that it is approximately 54. The remaining two SS-25 equipped divisions will start their upgrades to Yars in 2020, with the SS-25s expected to befully retired in 2021-2022, according to the commander of Russia’s Strategic Rocket Forces.

President Trump personally released the long-overdue Missile Defense Review (MDR) today, and despite the document’s assertion that “Missile Defenses are Stabilizing,” the MDR promotes a posture that is anything but.
Firstly, during his presentation, Acting Defense Secretary Shanahan falsely asserted that the MDR is consistent with the priorities of the 2017 National Security Strategy (NSS). The NSS’ missile defense section notes that “Enhanced missile defense is not intended to undermine strategic stability or disrupt longstanding strategic relationships with Russia or China.” (p.8) During Shanahan’s and President Trump’s speeches, however, they made it clear that the United States will seek to detect and destroy “any type of target,” “anywhere, anytime, anyplace,” either “before or after launch.” Coupled with numerous references to Russia’s and China’s evolving missile arsenals and advancements in hypersonic technology, this kind of rhetoric is wholly inconsistent with the MDR’s description of missile defense being directed solely against “rogue states.” It is also inconsistent with the more measured language of the National Security Strategy.
Secondly, the MDR clearly states that the United States “will not accept any limitation or constraint on the development or deployment of missile defense capabilities needed to protect the homeland against rogue missile threats.” This is precisely what concerns Russia and China, who fear a future in which unconstrained and technologically advanced US missile defenses will eventually be capable of disrupting their strategic retaliatory capability and could be used to support an offensive war-fighting posture.
Thirdly, in a move that will only exacerbate these fears, the MDR commits the Missile Defense Agency to test the SM-3 Block IIA against an ICBM-class target in 2020. The 2018 NDAA had previously mandated that such a test only take place “if technologically feasible;” it now seems that there is sufficient confidence for the test to take place. However, it is notable that the decision to conduct such a test seems to hinge upon technological capacity and not the changes to the security environment, despite the constraints that Iran (which the SM-3 is supposedly designed to counter) has accepted upon its nuclear and ballistic missile programs.
Fourthly, the MDR indicates that the United States will look into developing and fielding a variety of new capabilities for detecting and intercepting missiles either immediately before or after launch, including:
Developing a defensive layer of space-based sensors (and potentially interceptors) to assist with launch detection and boost-phase intercept.
Developing a new or modified interceptor for the F-35 that is capable of shooting down missiles in their boost-phase.
Mounting a laser on a drone in order to destroy missiles in their boost-phase. DoD has apparently already begun developing a “Low-Power Laser Demonstrator” to assist with this mission.
There exists much hype around the concept of boost-phase intercept—shooting down an adversary missile immediately after launch—because of the missile’s relatively slower velocity and lack of deployable countermeasures at that early stage of the flight. However, an attempt at boost-phase intercept would essentially require advance notice of a missile launch in order to position US interceptors within striking distance. The layer of space-based sensors is presumably intended to alleviate this concern; however, as Laura Grego notes, these sensors would be “easily overwhelmed, easily attacked, and enormously expensive.”
Additionally, boost-phase intercept would require US interceptors to be placed in very close proximity to the target––almost certainly revealing itself to an adversary’s radar network. The interceptor itself would also have to be fast enough to chase down an accelerating missile, which is technologically improbable, even years down the line. A 2012 National Academy of Sciences report puts it very plainly: “Boost-phase missile defense—whether kinetic or directed energy, and whether based on land, sea, air, or in space—is not practical or feasible.”
Overall, the Trump Administration’s Missile Defense Review offers up a gamut of expensive, ineffective, and destabilizing solutions to problems that missile defense simply cannot solve. The scope of US missile defense should be limited to dealing with errant threats—such as an accidental or limited missile launch—and should not be intended to support a broader war-fighting posture. To that end, the MDR’s argument that “the United States will not accept any limitation or constraint” on its missile defense capabilities will only serve to raise tensions, further stimulate adversarial efforts to outmaneuver or outpace missile defenses, and undermine strategic stability.
During the upcoming spring hearings, Congress will have an important role to play in determining which capabilities are actually necessary in order to enforce a limited missile defense posture, and which ones are superfluous. And for those superfluous capabilities, there should be very strong pushback.
The report covers many aspects of Chinese military developments. In this article I’ll briefly review the nuclear weapons related aspects of the report.
Overall, nuclear developments are not what stand out in this report. Although there are important nuclear developments, the Pentagon’s primary concern is clearly about China’s conventional forces.
Nuclear Policy and Strategy
The DOD report repeats the conclusion from previous reports that China has not, despite writings by some PLA officers (and occasional speculations by outside analysts), changed its nuclear policy but retains a no-first-use (NFU) policy and a pledge not to use nuclear weapons against any non-nuclear weapon state or in nuclear-weapon-free zones. That would, strictly speaking, include Japan, even though it hosts large numbers of U.S. forces.
The NFU policy, DOD says, has “contributed to the construction of [underground facilities] for the country’s nuclear forces, which plan to survive an initial nuclear strike.” Stimulants for the tunneling efforts were the 1991 Gulf War and 1999 Kosovo war, which made the Chinese realize how vulnerable their forces would be in a war with the United States.
Nor does the report indicate China has yet mated nuclear warheads to its missiles or placed nuclear forces on alert under normal circumstances. The report repeats the assessment from last that “China is enhancing peacetime readiness levels for these nuclear forces to ensure responsiveness.” That responsiveness is thought to ensure the force can disperse and go on alert if necessary.
The report mentions unidentified PLA writings expressing the value of a “launch on warning” nuclear posture, but it does not say China has adopted such a posture. A launch on warning posture would require high readiness of nuclear forces to be able to launch as soon as a warning of an incoming nuclear attack was received. China already has a “ready the forces on warning” posture that involves gradually raising the readiness level in response to growing tension in a crisis.
In U.S. military terminology, “launch on warning” is a higher readiness level than “launch under attack” because it would involve being able to launch upon detection that an attack was imminent but before incoming missiles had been detected. “Launch under attack,” in contrast, would require the force to be able to launch before incoming warheads hit U.S. launchers. The DOD report says the PLA writings highlight the “launch on warning” posture would be consistent with China’s no-first-use policy, which would imply it is more compatible with a “launch under attack” posture.
The DOD report also continues to describe China’s work on MIRV, the capability to equip missile with multiple independently targetable reentry vehicles. Rather than a sign of an emerging counterforce strategy, however, DOD states that the purpose of the Chinese MIRV program is to “ensure the viability of its strategic deterrent in the face of continued advances in U.S. and, to a lesser extent, Russian strategic ISR, precision strike, and missile defense capabilities.”
Indeed, the counterproductive effects of U.S. ballistic missile defenses on Chinese offensive force developments is clearly spelled out in the report: “The PLA is developing a range of technologies China perceives are necessary to counter U.S. and other countries’ ballistic missile defense systems, including MaRV, MIRVs, decoys, chaff, jamming, thermal shielding, and hypersonic glide vehicles.”
The growing inventory of ICBMs and SSBNs means that China has to improve nuclear command and control of these systems for them to be effective. It is unknown if Chinese SSBNs have yet sailed on a deterrent patrol (we assume not), much less with nuclear warheads onboard (we also assume not). But the growing and increasingly mobile ICBM force is carrying out extensive combat patrol exercises that place new demands on the nuclear command and control system.
A unique feature of the Chinese missile force is the mixing of nuclear and conventional versions of the same missiles (DF-21 and DF-26 have both nuclear and conventional roles). For China, this is a means to provide the leadership with non-nuclear strike options without having to resort to nuclear use. For China’s potential adversaries, it is a dangerous and destabilizing practice that risks causing confusion about the character of missile attacks and potentially trigger mistaken nuclear escalation in a conflict.
China has, like other nuclear-armed states, lowered the yield of its nuclear warheads as ballistic missiles became more accurate. The current warhead used on the DF-31/A ICBMs is thought to be ten times less powerful than the multi-megaton warhead developed for the DF-5. Moreover, as China seeks to ensure the survivability of its warheads against missile defense systems, it is likely to continue to try to reduce the weight and size of its warheads to maximize penetration aids on the missiles.
The DOD report mentions a “defense industry publication has also discussed the development of a new low-yield nuclear weapon,” but does not provide any details about the publication or what it said. The classified version apparently has more details.
The Land-Based Missile Force
The overall number of Chinese ICBM launchers reported by DOD has remained stable since 2011: 50-75. One type (DF-4) has reload capability, so the number of available missiles is a little higher: 75-100 missiles. That number has also remained stable for the past three years. Indeed, other than the arrival of the DF-26 IRBM force, the total Chinese rocket forces estimate is identical to that of presented in the 2017 report.
This indicates that the DF-31A force is not continuing to increase, that the DF-31AG has not yet been operationally deployed (or is replacing older DF-31s on a one-for-one basis), and that the DF-41 is still in development more than 20 years after it was first listed in the annual DOD report.
DOD’s reporting shows that the number of Chinese ICBM launchers has roughly doubled since 2003, while the number of missile available for those launchers has more than doubled. The numbers of missiles show a mysterious increase in 2016 from just over 40 to more than 80 (see table below). The increase is curious because it does not follow the number of launchers but suddenly jumps even though there was no corresponding increase in launchers that year.
The DF-4 is thought to have reloads but that system has been deployed since the 1980s. There is considerable uncertainty in the number of launchers (some years 25). The increase coincides with the deployment of the MIRVed DF-5Bs, so a potential explanation might be that there are two full sets of DF-5 versions. But it should be underscored that it is unknown if this is the reason.

The old liquid-fuel DF-4 (CSS-3) ICBM is still listed as operational, even though the relocatable missile will probably be replaced by more survivable road-mobile missiles in the near future. The DF-4 appears to be retained in a roll-out-to-launch posture.
The old, but updated, liquid-fuel, silo-based DF-5 ICBM is still listed in two version: the single-warhead DF-5A and the MIRVed DF-5B. This missile was first deployed in the early-1980s and is based in 20 silos in the eastern part of central China. There is no mentioning of a rumored C version.
The DF-31 and DF-31A are the most modern operational ICBMs in the Chinese inventory. First fielded in 2006 and 2007, respectively, deployment of the DF-31 appears to have stalled and DF-31A is operational in perhaps three brigades. Each missile can carry a single warhead. The DF-31AG is mentioned for the first time as an enhanced DF-31 with improved launcher maneuverability and survivability but may not yet be fully operational.
The long-awaited DF-41 ICBM remains in development and is listed by DOD as MIRV-capable. The report states that China is “considering additional launch options” for the DF-41, including rail-mobile and silo-basing. In silo-based version it would likely replace the DF-5.
The medium- and intermediate-range nuclear missile force is made up of three types: the new DF-26 IRBM, which is dual-capable and able to conduct conventional (both land-attack and anti-ship) and nuclear precision attacks; and two versions of the DF-21: DF-21A and DF-21E. The DF-21 A (SSC-5 Mod 2) has been deployed since the late-1990s. The DF-21E (note: the E designation is not official but assumed) is known as the SSC-5 Mod 6 and was first reported in 2016. The DF-21 also exists in two conventional versions: DF-21C and DF-21D (anti-ship).
The dual-capable DF-26, first fielded in 2016, is capable of conducting “nuclear precision strikes against ground targets.” There appears to be one or two DF-26 brigades.
The role of the new Strategic Support Force is listed as intended to “centralize the military’s space, cyber, and EW [Early Warning] missions. These would probably support the rocket force.
The Submarine Force
The DOD report says that China still operates four Jin-class (Type 094) SSBNs (all based at Hainan), each of which can carry up to 12 JL-2 SLBMs. At least one more Jin-SSBN is said to be under construction. Construction of a new SSBN (Type 096) may begin in the mid-2020s with a new SLBM (JL-3). DOD speculates that Type 094 and Type 096 SSBNs might end up operating concurrently, which, if accurate, could increase the size of the total SSBN fleet.
China also operates five Shang-class (Type 093/A) nuclear-powered attack submarines, with a sixth under construction. The Shang has now completely replaced the old Han-class (Type 092). DOD anticipates that a modified Shang (Type 093B) equipped with land-attack cruise missiles may begin building in the early-2020s. [Note: while many public sources call the two existing Shang versions Type 093A and Type 093B, the DOD report calls them Type 093 and Type 093A. The Type 093B is listed as a future type that until 2016 was called Type 095.]
Overall, China operates 56 submarines, of which 47 are diesel-electric. The report projects this force may increase to 69-78 submarines by 2020, a significant increase in only two years.
One of the most interesting nuclear developments in the DOD report is the assessment that “the PLAAF has newly been re-assigned a nuclear mission.” This contrasts with last year’s report, which stated the “PLAAF does not currently have a nuclear mission.” The “re-assignment” indicates that the bombers previous had a nuclear mission. We have estimated that a small number of bombers had a dormant nuclear capability for gravity bombs as indicated by their extensive role in the nuclear weapons testing program and China’s display of nuclear bombs in military museums.
The DOD report states that the H-6 and the future stealth bomber could both be nuclear-capable. The future bomber, according to the DOD report, could potentially be operational within the next ten years.
The report repeats the estimate made by the U.S. Intelligence Community from the past two years that China is upgrading its aircraft with two new air-launched ballistic missiles, one of which may include a nuclear payload.
The biggest surprise in the Pentagon’s latest annual report on Chinese military power is the claim that China’s ICBM force now includes the “multiple independently-targetable re-entry vehicle (MIRV)-equipped Mod 3 (DF-5).”
This is (to my knowledge) the first time the US Intelligence Community has made a public claim that China has fielded a MIRVed missile system.
If so, China joins the club of four other nuclear-armed states that have deployed MIRV for decades: Britain, France, Russia and the United States.
For China to join the MIRV club strains China’s claim of having a minimum nuclear deterrent. It is another worrisome sign that China – like the other nuclear-armed states – are trapped in a dynamic technological nuclear arms competition. Continue reading →
In the wake of recent problems related to Air Force officer morale and test cheating, 60 Minutes examined the U.S. land-based nuclear missile program, one part of the nuclear triad which includes submarines and bombers. Reporter Lesley Stahl visited an underground control room at F.E. Warren Air Force Base in Cheyenne, Wyoming and spoke to the young officers who watch over these weapons which are on high alert. The control centers were built in the 1960s and due to aging infrastructure, officers who oversee the world’s deadliest weapons are working with computers so old they use floppy disks and outdated, faulty phones.
Hans Kristensen, Director of the Nuclear Information Project, worked with the production team of this piece to provide factual information on the status of the U.S. ICBM force. In 2013, FAS and the Natural Resources Defense Council examined the status of U.S. and Russian nuclear alert forces and provided recommendations to reduce the alert levels of nuclear forces; the report is available here.
