Dazed and Confused by RRW — Part 4

Welcome to the final post in my series on the Reliable Replacement Warhead (RRW) pro­gram and the future of U.S. nuclear stock­pile stew­ard­ship. In this post, I’ll review where RRW stands today, and touch briefly on some of the polit­i­cal dimen­sions of the debate over the pro­gram.
There’s a lot of mate­r­ial on this pro­gram from the gov­ern­ment, from out­side experts and from pol­icy advo­cates of all ori­en­ta­tions that I won’t be able to cover, so to those inter­ested in read­ing more, I rec­om­mend check­ing out CDI’s guide to gov­ern­ment doc­u­ments on RRW, as well as arti­cles on the pro­gram at the Arms Control Association web­site and over at Arms Control Wonk.
w76.jpgIn May 2005, the two nuclear design labs, Los Alamos and Lawrence Livermore, began an 18-​​month RRW Feasibility Study, as man­dated in the fis­cal year 2006 Defense Authorization Act. The study con­sisted of a design com­pe­ti­tion between the two labs (both with help from Sandia) to pro­duce plans for the first RRW war­head, a replace­ment for the W76 submarine-​​launched bal­lis­tic mis­sile war­head.
The pre­lim­i­nary designs were com­pleted and sub­mit­ted in March, and under­went peer review in the labs in May. Currently, the teams are back at the draw­ing boards, incor­po­rat­ing sug­ges­tions from the peer reviews and from the Project Officers Group, the rep­re­sen­ta­tives of the nuclear stockpile’s Department of Defense “cus­tomers.” By November, NNSA is expected to pick a win­ning design.
As reported in Defense Tech last week, how­ever, RRW is well on its way to expand­ing beyond a sin­gle war­head design. It has been clear for some time that one RRW design would not be enough to replace all nine war­head mod­els cur­rently in the stock­pile. Still, many RRW observers were dis­ap­pointed and con­cerned to hear that the Senate is plan­ning to com­mis­sion a design com­pe­ti­tion for the next RRW war­head and to allo­cate $62 mil­lion for RRW in 2007 more than dou­ble the depart­ments $27 mil­lion request, and the pro­grams $25 mil­lion bud­get for 2006 before the first fea­si­bil­ity study is even com­pleted.
The argu­ments in favor of RRW have mostly been described in pre­vi­ous posts: redesign­ing the stock­pile to increase per­for­mance mar­gins would, if pos­si­ble, help put to rest con­cerns about the effect of mod­i­fied man­u­fac­tur­ing prac­tices on war­head per­for­mance, and would pro­vide work for the nuclear weapons com­plex.
The argu­ments against RRW, mean­while, take issue with both the pro­grams desir­abil­ity and its fea­si­bil­ity.
The first argu­ment against the pro­gram is that, accord­ing to the pro­grams oppo­nents, there is no need to change the cur­rent war­head designs. In the exam­ple of the pit reman­u­fac­tur­ing debate dis­cussed in my last post, this means that the pro­grams oppo­nents believe that the new pits have been proven con­clu­sively to be as reli­able as the old pits, and can be incor­po­rated into exist­ing war­heads.
(Dr. Jeanloz, by the way, is on the record as an RRW “skep­tic,” rather than an out­right critic, but sev­eral other experts have offered views sim­i­lar to his as argu­ments against RRW.)
NTS.jpgThe sec­ond main argu­ment against RRW is that a sig­nif­i­cantly mod­i­fied war­head design which has not been tested can­not pos­si­bly be as reli­able as a tested design. Critics who advance this argu­ment point out that inde­pen­dent assess­ments pre­dat­ing RRW by gov­ern­ment advi­sory bod­ies such as the JASONs found that “entirely new designs for the nuclear sub­sys­tem… would be expected to require nuclear-​​explosion (under­ground) test­ing before being accepted for the endur­ing stock­pile.“
This assess­ment con­tra­dicts the NNSAs assess­ment that the RRW designs will “be cer­ti­fi­able and pro­ducible with­out nuclear test­ing” even though the plans call for “redesign­ing” the war­heads’ nuclear sub­sys­tems. Nuclear test­ing is almost uni­ver­sally regarded as a very bad thing the Bush Administration is for­mally com­mit­ted to con­tin­u­ing the cur­rent test­ing mora­to­rium, in no small part due to con­cern that a U.S. test would inevitably lead to Chinese and Russian tests.
Critics who cite this con­cern point out that even if the nuclear weapons com­plex ever brought itself to cer­tify a war­head design which had never been tested, U.S. Strategic Command, as the stockpile’s “cus­tomer,” would be unlikely to accept such an unproven prod­uct.
It is worth not­ing, by the way, that there are cer­tain mod­est mod­i­fi­ca­tions which can increase war­heads’ per­for­mance mar­gins to a cer­tain extent with­out adding uncer­tainty these changes are not con­tro­ver­sial, and are being con­sid­ered out­side of RRW.
Finally, crit­ics point out that the program’s sup­posed con­tri­bu­tions to the goal of “stock­pile trans­for­ma­tion” are not con­sis­tent with each other.
On the one hand, RRW is sup­posed to lead to long-​​term cost-​​savings by pro­duc­ing a stock­pile which can be main­tained with­out a com­plex stock­pile stew­ard­ship effort. On the other hand, RRW is also sup­posed to “con­tin­u­ously exer­cise” the nuclear weapons com­plex and “enable” the tran­si­tion to a “respon­sive infra­struc­ture.“
The two goals are clearly incom­pat­i­ble a good-​​for-​​a-​​century war­head design which met Congress’ goal of reduc­ing the cost and com­plex­ity of stock­pile main­te­nance would not meet NNSA’s goal (and Congress’ sec­ondary goal) of keep­ing the pro­duc­tion com­plex “exer­cised” for a pos­si­ble future arms race. (Ryan jokes that to some peo­ple, RRW seems to stand for “Reliably Recurring Work.”)
signpost.jpgAs the Congressional Research Service points out, “RRW is a new pro­gram with no spe­cific, tan­gi­ble prod­uct yet defined. In decid­ing how to pro­ceed on RRW, Congress has a num­ber of options avail­able to it.” It is pos­si­ble that a ver­sion of the pro­gram will emerge which can sat­isfy the con­cerns of all sides of those who worry that the cur­rent stock­pile stew­ard­ship par­a­digm will lead to a dan­ger­ous accu­mu­la­tion of minor changes, and of those who worry that a sig­nif­i­cant over­haul of war­head designs will destroy, rather than for­tify, con­fi­dence in the stock­pile. Until such a ver­sion emerges, though, we can expect to see both con­fu­sion and con­tro­versy con­tinue to rage.

    We just need to slip the French, Indians, or Pakistanis a bil­lion or so and “bor­row” their under­ground test ranges for a quick ver­i­fi­ca­tion test…

    Don’t for­get, the French “under­ground test range” is an arch­i­pel­ago in the South Pacific… got to hand it to the French, even thirty years of inter­na­tional norms couldn’t dis­suade them from throw­ing their nuclear test­ing bashes on a trop­i­cal beach!

    Reliability of Weapons Fuzing is absolutely crit­i­cal in con­truct­ing a War Plan. We need to ensure ongo­ing and future device reli­a­bil­ity for our National Survival regard­less of the “pol­i­tics”. In addi­tion; new designs to include reli­able earth-​​penetration war­heads and reduced-​​blast war­heads (read: enhanced radi­a­tion war­head) should be renewed to com­ple­tion. We will be at war with the Chinese Communist’s no later than 2050. Klinton & Gore (both should be shot as traitor’s) gave them our W-​​88 war­head design & allowed them to aquire guidence pack­ages which just proved their effec­tive­ness in an anti-​​satellite shot. We need to wake-​​up and pre­pare for the future. Indeed; we are not equiped to han­dle Iran!
