GLOBAL ZERO COMMISSION ON NUCLEAR RISK REDUCTION REPORTDE-ALERTING AND STABILIZING THE WORLD’S NUCLEAR FORCE POSTURESThe popular narrative of the Cold War slid past these facts<strong>on</strong> the ground in favor of the abstract theory that the <strong>nuclear</strong>arsenals provided a stable balance of terror based <strong>on</strong> mutualassured destructi<strong>on</strong> (MAD). Every instituti<strong>on</strong> of Americansociety accepted and even internalized the narrativethat U.S. <strong>nuclear</strong> forces were prepared to absorb the worstattack the enemy could mount, and then mount a counterattack<strong>on</strong> presidential orders that would destroy the attacker’sec<strong>on</strong>omy and populati<strong>on</strong>. A rati<strong>on</strong>al adversary would neverdare to strike under these c<strong>on</strong>diti<strong>on</strong>s. Moreover, the factthat the Soviets could do the same to the United States <strong>on</strong>lystrengthened the stability of mutual deterrence, accordingto a narrative that led many people to celebrate rather thanlament the mutual vulnerability of entire populati<strong>on</strong>s.Those resp<strong>on</strong>sible for carrying out the <strong>nuclear</strong> missi<strong>on</strong> knewotherwise. In the real world, U.S. and Soviet <strong>nuclear</strong> strategyyielded operati<strong>on</strong>al postures that could not reliably ride outan attack. They were geared to such rapid and massive reacti<strong>on</strong>to signs of enemy attack that little room was allowedfor rati<strong>on</strong>al deliberati<strong>on</strong> and real leadership in a crisis. Rotedecisi<strong>on</strong>-making and rapid enactment of a prepared scriptwere the orders of the day <strong>on</strong> both sides. The dynamic interacti<strong>on</strong>of their operati<strong>on</strong>al postures in the midst of a c<strong>on</strong>fr<strong>on</strong>tati<strong>on</strong>carried grave <strong>risk</strong>s of losing c<strong>on</strong>trol and sparkingan intenti<strong>on</strong>al or inadvertent <strong>nuclear</strong> c<strong>on</strong>flict. The situati<strong>on</strong>was anything but stable.As a technical matter, nothing has essentially changed sincethen.Planning to launch <strong>on</strong> warning is obviously a cosmic gamble,given the significant <strong>risk</strong> of ill-c<strong>on</strong>sidered judgmentbased <strong>on</strong> incomplete or false informati<strong>on</strong>. And indeed, Russiaand the United States have come close to disaster <strong>on</strong> severaloccasi<strong>on</strong>s involving false alarms. 70 And yet, PresidentObama in 2013 reiterated the need to maintain the capabili-70 For informati<strong>on</strong> <strong>on</strong> known close calls see Patricia Lewis et al, “TooClose for Comfort: Cases of Near Nuclear Use and Opti<strong>on</strong>s for Policy,”Chatham House Report, April 2014, http://www.chathamhouse.org/sites/files/chathamhouse/home/chatham/public_html/sites/default/files/20140428TooCloseforComfortNuclearUseLewisWilliamsPelopidasAghlani.pdf.ty for prompt launch in his <strong>nuclear</strong> employment guidance. 71The half-life of this tactic is l<strong>on</strong>g indeed.The <strong>risk</strong> of mistaken launch would appear to be even highertoday because of the decrepit state of Russia’s early warningnetwork. For many past years Russia’s obsolescing earlywarning satellites provided <strong>on</strong>ly a few hours of reliablelaunch detecti<strong>on</strong> coverage over the U.S. Minuteman fields.In the fall of 2014, Russia lost its last two remaining functi<strong>on</strong>alearly warning satellites m<strong>on</strong>itoring that area. 72 Lackingspace-based coverage of U.S. Trident missile launchesfrom the Atlantic and Pacific oceans, Russia now dependscompletely up<strong>on</strong> ground radar sites to detect and assess incomingU.S. ballistic missile warheads fired from land orsea. Russia’s ability to detect low-flying <strong>nuclear</strong>-armed cruisemissiles fired by bombers or submarines is even worse.As the graph below shows, the lack of satellite early warningdrastically reduces the timeliness of Russian detecti<strong>on</strong> of aU.S. strategic ballistic missile attack. Russia’s radar detecti<strong>on</strong>timelines vary from ten minutes for a U.S. submarine missilefired from the Norwegian Sea to 17 minutes for a U.S.land-based missile raid launched from a Minuteman field inthe Midwestern United States. 73 By comparis<strong>on</strong>, U.S. warningsensors provide nearly twice as much warning time (18-28 minutes) of a Russian strategic strike, assuming Russiadoes not deploy its ballistic missile submarines closer to U.S.shores. However, the U.S. ability to detect Russian <strong>nuclear</strong>-armedcruise missiles flying at low altitudes is very poor.Russia’s attack indicati<strong>on</strong>s emanate from ground radar <strong>on</strong>ly,whereas two types of U.S. detecti<strong>on</strong> systems – ground radar71 U.S. Department of Defense, “Report <strong>on</strong> Nuclear Employment Strategyof the United States Specified in Secti<strong>on</strong> 491 of 10 U.S.C.,” Washingt<strong>on</strong>,D.C.: June 12, 2013, p. 5.72 See Pavel Podvig, “Russia lost all its early-warning satellites,” Russianstrategic <strong>nuclear</strong> forces (blog), February 11, 2015 http://russianforces.org/blog/2015/02/russia_lost_all_its_early-warn.shtml.73 These are maximum performance estimates that may not be realisticat the present time because Russia has not yet completed the modernizati<strong>on</strong>of its ground radar warning network. Some newer radars may beoperating in “test” mode and may not come <strong>on</strong>line with full operati<strong>on</strong>alcapability for some time.36

This “dualphenomenology” redundancy is lacking <strong>on</strong> the Russia side,although a U.S. missile raid that is big enough to threatenthe survival of the Russian ICBM force is almost certainlygoing to be picked up by multiple Russian ground radars.And so there would be some means of cross-checking thevalidity of attack indicati<strong>on</strong>s <strong>report</strong>ed by any given Russianradar site.strain as it fields a variety of new weap<strong>on</strong>s. Russia <strong>report</strong>edlyis now deploying missiles in Crimea capable of carrying<strong>nuclear</strong> warheads 75 and will possibly deploy tactical <strong>nuclear</strong>weap<strong>on</strong>s there, including for its Black Sea fleet. Russiais developing a train-mobile strategic missile. It is testing anew ground-launched cruise missile of intermediate rangeand may decide to withdraw from an existing treaty signedby Russia and the United States in which such missiles arebanned. A force of hundreds may emerge. And Russia hasother <strong>nuclear</strong> weap<strong>on</strong>s in the pipeline that will pose a newset of command-c<strong>on</strong>trol challenges.Russia’s scattered arsenal is in perpetual moti<strong>on</strong> over ninetime z<strong>on</strong>es – moving around <strong>on</strong> combat alert and shuttlingback and forth to repair facilities at their main field bases.Warheads and bombs from the field are transported for routinemaintenance several times per year. 76 Every ten years, <strong>on</strong>average, they are also transported l<strong>on</strong>g distances to nati<strong>on</strong>almanufacturing facilities to re-forge their plut<strong>on</strong>ium pits.(Russian pit shelf-life averages <strong>on</strong>ly 8-12 years compared to80 years for U.S. pits.) Thus overall more than ten percent ofthe Russian <strong>nuclear</strong> arsenal is in transit during a given year.Since transportati<strong>on</strong> is the Achilles heel of <strong>nuclear</strong> security:this c<strong>on</strong>stant movement runs a <strong>risk</strong> of terrorist capture.These timelines 74 are obviously very compressed <strong>on</strong> bothsides. The opportunities for ill-c<strong>on</strong>sidered <strong>nuclear</strong> decisi<strong>on</strong>-makingare extensive regardless of the accuracy ofincoming early warning <strong>report</strong>s. Launch <strong>on</strong> warning putsenormous strain <strong>on</strong> the <strong>nuclear</strong> chains of command in bothcountries.But the humanitarian c<strong>on</strong>sequences of a tragic mistakewould not be c<strong>on</strong>strained by the nati<strong>on</strong>al borders of Russiaand the United States.
