HlSJORY OF THE JOINT STRATEGiC TARGETPLANNING STAFFIntroduction Th mission ot the Joint Strategic Target Planning Staff( STPS) was to prepare and maintain, on a day-by-day basis, a NationalS rategic Target List (NSTL) selected for' attack in a nuclear war anda Single Integrated Operational Plan (SIOP) for the attack of these1tcoordinated forces.Assumed enemy awareness0SlOP's existence and its damaging potential acted as a barriertoutbreak of nuclear war.Contribution to "deterrence" wasp rceived as a major purpose of the SlOP--a plan which was supportedbNavy's submarine-launched missiles, the land-based missilesbombers of the Strategic Air Command (SAC), and such fighter-mera and missile systems committed to the plan by unified comders.2(U)The JSTPS functioned as a staff agency of the Joint Chiefs(JCS) from which it received directions.Above the JCS wasDepartment of Defense, with the chain of command culminating athighest level in the National Command Authorities (NCA).TheJS PS, however, was collocated with Headquarters Strategic Air Command( C) at Offutt Air Force Base, Nebraska,(U)3This arrangement dated from August 1960 when Secretary ofDe ense Thomas S. Gates, Jr. founded the JSTPS in what he laterre erred to as his most important decision.It was part of hisde ision to collocate it with Headquarters SAC in order to gain thead antages of SAC expertise and computer abilities, already highlyde eloped at that time.thIt was also part of the same decision thatCommander in Chief, Strategic Air Command (CINCSAC), should alwaysse ve as Director of the JSTPS, while the Deputy Director wouldincome from another service.ofthe U.S. Navy had always filled the latter position.reinder of JSTPS personnel were drawn from all the military services.In point of fact, a flagThe4

(U)possessioBy 1960, advances in nuclear technology had led to theof nuclear weapons by various U.S. commands whose plansfor their respective use were apt to conflict with each other.Unravelinr espect,such conflicts became increasingly burdensome and in thiss well as others, the advanced technology led to duplica-tion of e fort.The JSTPS was created in order to provide centrallycontrolle operational planni.ng for the use of nuclear weapons int of national objectives.5· For several years after the JSTPS started operation, aprepared, at least in theory, each fiscal year (FY).on, however, fluctuations in the numbers and types ofapons available,(b cre s-s-:i:-t-a t e"':'d r e v i';"'s"-i -o---:n of,.---- ----'-at six-mon h intervals.theA policy change to alphabetically designatetook place in 1967, when SIOP-4 was in effect.Eventually SIOP-4 went into Revision 0, but then it proceededof Revision 0, known as OX, for a six-monthperiodDecember 1974.1 July 1976 'The 18-month period betweenand 31 December 1974 was, therefore, very much of aninterim or changeover period as regards SlOP planning.It was wellbefore SIO -4N had run its course that the JSTPS received authoritativeword thatfuture.fact, replace SIOP-4 in the rela tively nearearly as 1970, the President had made public statementsandchange of thinking as regards employment of nuclear force,7rated similar thoughts in the intervening years .o Revision N was, in a very real sense, the last of theof regular six- month SIOP revisions and just aboutas it went nto effect, the JSTPS people realized that they had enteredan interim eriod as regards SlOP planning.That this was indeed thecase was qu ckly confirmed by the nature of the tasks which the JCSsoon starte giving the JSTPS.associatedIt was the additional workloadith these tasks that resulted in the six-month extension2

oThese s-pecial tasks were involved in one way ora other with U:1e anticipated change from SIOP-4 to SIOP-5. 8l evision0. 'l'hough a SIOP revision was effective for a period - fs x months, the complete life cycle of any revision, includingP anning, was approximately two years; that is, planning for aat a point from 15 to 18 months before it was toThere were numerous steps in the planning processga d it so happened that they had to follow a well-defined order,t at is, that one specific step would have to be completed, or nearlyso, before the next could begin.Many of the processes were of aso the JSTPS had to allow not only fortial calculations, but also for computer time to check theiruracy. 9 natural outcome of this situation was that the planningiod between two different SlOPs would also require a long leadA normal SlOP revision involved a workload sufficient tothe JSTPS on a continuing basis.The move from an old to aSlOP with differing concepts involved, in addition, extra studies,e of them quite extensive, to pretest the validity of the newThere were also additional meetings.The JCS instructedto perform much of this extra workload in addition to its10production of SlOP revisions. SIOP-5, with its new concepts, represented a major changenuclear war planning.tty much the same.Previously, the basic concepts had remainedThe comparatively minor changes that had occurred,continue to occur, had been occasioned primarily by two(1) changes in the number and kinds of weapons available,11(2) growth of the enemy target system. By the time Revision N became effective, Revision 0 wasinto the planning stage, but even before it went into effect, theS knew that the next logical step would be an extension of thisThe JSTPS looked upon the extensionfra kly as a "patch-on-an-inner tube" type of makeshift arrangement3

(b)( 1)(U)Pr esiden(U)-In his Annual Report on Foreign Policy in February 1970, !chard M. Nixon stated: 29-Should a President , in the event of a nuclear attack,be left with the single option of ordering the massdestruction of enemy civilians, in the face of thecertainty that it would be followed by the massslaughter of Americans? Should the concept of assureddestruction be narrowly defined and should it be theonly measure of our ability to deter the variety ofthreats we may face?"30A year later, he repeated the same thought .I must not be--and my successors must not be--limitedto the indiscriminate mass destruction of enemy civiliansas the sole possible response to challenges . This isespecially so when that response involved the likelihoodof triggering nuclear attacks on our own population. Itwould be inconsistent with the political meaning ofsuffi ciency to base our force planning solely on somefinite--and theoretical--capacity to inflict casualtiespresumed to be unacceptable to the other side.{U)He reiterated statements calling attention to a need forthis type of policy change in subsequent reports to Congress in 1972and 1973.Thus was set in motion the progression from the conceptsembodiedSIOP-4 to those forming the basis of SIOP-5 and a t the8

According to this schedule, 15 August was setashe date to start figuring out the ranges for the bombers andmating them with tankers, t his pr ocess to be completed by 15 OctoberI1973 .Fo r ce application was to start on 2 October.

Extensionof the in-effect revision vice preparation of anorma! revision resulted in time savings which could be applied to .the a alyses and reviews required to assure successful implementationof thforthcoming SIOP-5.As of February 1973, the JSTPS was stillconsi ering the possibility that SIOP-5 might go into effect as earlyI119as l nuary 1975.It was 15 July 1974 before the JCS set 1120Jan1976 as the date for starting with SIOP- 5. Essentially,then, effort that not111ally would have goneinto l:::sion P went, instead, into two channels. Of the forcescommi1 lted to Revision P, JSTPS programmed into Revision OX only somuch as represented a difference from those initially committed toRevis;n 0, thereby gaining manhours and computer time to devote toprepa ations for SIOP-5. For example, when the Strategy Panel woUldnormay have been convened in November 1973 to work on Revision P,the lover level Strategy Working Group met instead at that time to121discus problems pertinent to the extension.
