1. General.

a. This Annex supplementsAnnex C to CJTF SEVFN OpPlan3-53, the provisionsof which are applicableto all ships and units of this tommand.

2. Area of Onerations.

a. ENIWETOKand BIKINIAtolls are part of the Trust Territoryof the Pacific Islands,placed under the United Statesas the administeringauthor- ity by the SecurityCouncil of the United Nations, They are, therefore, subject to the full powers of administration,legislation and jurisdiction of the United States, The trusteeshipagreement for the Trust Territory permits the United States to close any of the areas for securitymasons.

b. On 2 December194’7, by notificationto the United Yations,the United Statesclosed the area of the entire ENIYETOKAtoll and the territorialwaters adjacentthereto. On 13 December1948, the State

Departmentconcurred in the establishmentfor an indefiniteperiod of a l Danger Zone aroundENIJETOK Atoll.

C* On 1 April 1953, BIKINI Atoll and the adjacentwaters thereto,was also closed by notificationto the United Nations, On 2 April 1953 the United Statesexpanded the ?L?IUXFTOKDanger Area to includeBIKINI Atoll. Danger Area noticeswere publishedin air and marine ~vi~tional notices and in the press. The State Departmentnotified all foreign governments concerningthis expansion.L

3. Eh.mmrvof Enemy Canabilities.

a. It is consideredthat interferencewith the Joint Task Force SEV?3N mission or compromiseof its activitiescould be effectedby:

(1) Espionape. Fspionage,or "spying",for the purposeof CASTLE, would involvethe unauthorizedcollection of classifiedor Ip.STKICT5.)DATA informationfor a foreigngovernment. It includesthe collection(by observation,theft, sketching,photography, etc.) of the informationas well as its delivery,together with assisting,harboring or concealingpersona involved. Qpionage could be acuomplishedby the penetrationof foreign agents into the Joint Task Force, or by the defectionof personnelof the Joint Task Force.

(2) Sabotage. Sabotage (destructive,delaying or impendinga&s) could be accomplishedby the penetrationof subversivepersonnel into the Task Force,the defectionof personnelof the Task Force, or more remotely, by a raidingparty landed from the sea or from aircraft. Subversiveaction by these means could run along the lines of the destructionof communications and technicalinstallation facilities within the atoll.

D-2 c @ration Flan CTG 7.3 No. 1-53

(3) Overt Action by Vessel or Aircraft. Overt actionby vessel or aircraftcould take the form ofyzck by bomb, guidedmissile, gunfire or assault,

(4) Raids. Raids could be conductedby aggressiveor surreptitious methodsunder the cc~er of darknosefrom ships and submarines,or possibly, from aircraft. The landingand recoveryof raidersby submarino'couldbe accomplishedunder the conditionsof darknessand the confusionresulting from their activities.

(5) Photographyand Observation. Compromisecould be accomplished by photographicmeans from surfaceship, aircraftor submarine. Unobserved submarineapproach within one mile of importantislands of the atoll or overflightby unfriendlyaircraft are possible. In addition,a determined surfactship commandermight attemptto compromisethe operationsby overt observationof activitiesin the area from immediatelyoutside the three (3) mile limit. By such means, periodicphotography and observationcould record and interpretthe progross,process of preparation,types of constructionand the approximatetime of importantoperations from the activitieswithin the atoll.

(6) @uthoriscd Instrumentation.Means under this headingfor obtainingunauthoriacd information would includepressure, heat and radiation detectiondevices as well as radioactivematerial collection devices.

(7) Declarationor Commencementof War. In the event of the commencementof war, by declarationor otherwise,involving the United States,the nature and extent of CASTLE Operationsmight be radically changed. It is difficultto predict the exact nature of theso changes, but if the Operationwere continued,partially, wholly or augmentedin scope, a completere-evaluation of enemy capabffltiesand intentions would be necessary.

b. USSR Naval Capabilities.

(1) SubmarineCanabilitiE. If he decided to utilisehis sutirine capabilityto obtain informationconcerning, or to interferewith, CASTE3 Operations,the Sovietmight employ submarinesas follows: DBiA (A) To instrumentthe shots by the employmentof pressure, heat and radiationmeasuring instruments located on board. The submarine probablywould have to come to the surfaceto employ these instruments, althoughit is not impossibleto mount them on periscopicextensions from a submergedsubmarine in which case the detocticnof the submarinewould

D-3 ,, --

Operation Plan CTG 7.3 No. l-53 be much more difficult. Useful information by this means could be obtained at considerable distances frcnz the Atoll.

(B) To observe and photograph the installations and detonations. The limitations of submarine periscope observation and photography are such that a submarine would have to qproach within three (3) miles, and preferably one (1) mile, to obtain useful information of shot sites. Even then, it is highly doubtful if any dotailed informationcould be obtained,but only informationindicating the generalprogress of work, includinginstrumentation. Radar observationor radar photographscould supplementthe information obtainedby other means. Useful visual,radar or photographicinformation of the detonationscould, of aourse,be obtainedfrom much greaterdistances.

(C) Direct attack by gunfirecould harass the operationbut would probablyresult in little damage to installationsor injuryto personnel, On the other hand, such attackswould result in the detectionand probable eventualdestruction of the submarine. Whileno informationis available indicatingthat the USSR have modified submarinesfor guidedmissile launch- ing, there is no reason to believe that they could not do so if they so desired, in view of the rolatix3y simplemodifications required and the widely publicizedW.S. accomplishmentsin this field. A properlydirected, submarine-launchedguided missile, fitted with an atomic warhead,could inflictgreat damage to installationsand injuryto personneland thus seriouslyinterfore with the Operation. USSR su~arines also have the capa- bility of attackingships of the Joint Task Force with torpedoes. The presence of an escortcould indicatethat the ship or ships escortedare considered valuable. It is considered that direct attackprobably would precedeor accompany the openingof hostilitiesby the USSR, althoughthe USSR might possiblytake the risk of attemptingto launchan undetectedsubmarine- launchedguided missile in the hope that the resultingatomic explosion might be considered (by the U.S.) as the accidental or premature explosion of one of the test devices or a component thereof.

CD) FMds ad Sabotage. As disc~sed above.

(T) Iagoon penetration could be attempted by a submarine assigned any of the foregoing missions. However, lagoon penetration is not necessary for the accomplishment of any of them and involves definite additional risks of detection and destruction. IIMA (2) Other USSR Naval Capabilities. US,59 surface ships also have . capabilities for unauthoriazd instrumentation, cbservation, photography, landing of raiders and saboteurs and direct attack, but except as noted below, it is most unlikely their eqloyment would be attempted,short of actual :. . * . t

D-4 OperationPlan CTG 7.3 No. 1-53 hostilities,in view of their insbilityto approachthe OperationalAtolls undetected. There is a possibilitythat the USSR night attempt the employment of small surfacecraft, such as fishingboats, for instrumentationand obser- vation. There is a more remote possibilitythat the Sovietmight attemptthe landingof raidersor saboteursfrom a small,fast surfacecraft launchedfrom a larger surfacevessel. As in the case of submarines,attemptid lagoon pene- trationis possiblebut unlikely.

c. USSR Air Capabilities.No informationin additionto that sat forth in Annex C to CJTF SEVEN OpPlan 3-53.

d. Conclusions.Of the foregoingcapabilities, the followingare those which it is consideredthe USSR is most likelyto attempt,under present world conditions:

(I) Espionage,

(2) Unauthorizedinstrumentation by submarine,surface vessel or aircraft.

(3) Observationor photographyby submarineor aircraft.

(4) Sabotage.

If it decidedto initiatewsr with the U.S., the Sovietmight well attempt overt action (directattack) by ships or aircraft,or raids, immediately precedingor in conjunctionwith the openingof hostilities.

The regulations set forth herein have been designed as e. reasonable and safe compronise bonsidering conserv&ion of personnel exposures, the international Import of the test and the cost aspects of operational delays chargeable to excessive radiolo&al precautions. In. all cases other than emergencies br tactical‘situations, the ultimate criteria will be limited by the YES for gersonnel. Special instanues may arise such as in the case of an air-sea rescue within the Badex, or in the case of a tactical situation, in which operations will be carried out.with- But regard to the NSs and ML& prescribed herein. For such energency or . tactical operations. the criteria prescribed below for tactical situations will be used as a guide.

$,L-c0 Hazardsmfrom,,Atomic Bomb Explosions /I 1. Nature of Hazards

a, When an atoticbomb explosionoccurs, tremendous quantities of energyin a varietyof forms are released. This energyis propagatedout- ward in all directions,

b. The immediatereaction is intenseemission of ultraviolet,visible and infrared (heat)radiation, gamma rays and neutrons. This is accom- panied by the formationof a large ball of fire. A large part of the energyfrom the explosionis emLttedas a shockwave. The ball of fire producesa mushroom-shappedmass of-hot gases,the top of which rises rapidly. In the trail below the mushroomcap, a thin columnis left. The cloud and column are then carrieddownwind, the directionand speed being determinedby the directionand speed of the wind at the variouslevels of air from the surfaceto base of mushroomoap. Part of the energy from the exposionresults in an oceansurface wave which is consideredof minor nature directlyto the Task Force,

c. AILLpersonnel of the Task Force will be weU. outsideof the range of all hazards at the time of detonation,except for the light from the fire ball, The light of exp&esienis so intensethat permanentinjury to the eye may result from viewingthe'ball of fire at close rangewith the naked eye or through binoculars. Ordinarydark glasseswill not suffice and all personnelwho do not have the specialprotective glasses, which will be issued in limitednumbers by CTG,?.l,must be facing186 degrees from the detonationwith the eyes closed.

d. The emissionof &agerious nuclear radiationcan be separatedinto two time periods. The primaryradiation which occurs at the time of the flash is composedof gannnarays and neutrons. Casualtiesmay result from this primaryradiation if the exposureoccurs within a certainrange of ground zero* Secondaryradiation is due to activationof the soil ar~wu3 ground zero and to fall-out.

e. Followingthe detonation,personnel entering shot areas will be ekposed to beta particlesand gamma rays comLngfrom inducedneutron activityin the soil and/orwater, andcay fissionproducts which might have been depositedon the ground or in the water. There may also be a potentialalpha particlehazard from the unfissionedfissionakile materials which may be deporiitedon the ground or in the water.

2. Protection

a. Againstthe primaryradiological effects, distance will provide protection.

b. 'Against_ the secondaryradioactivity hazards from radioactivefission products,induced radioactivity and unfissionedresidue, detection and ‘avoi-d- ante providethe best protection,.Suitable instruments indicate both the presenceand intensityof radioactivityat a given place. Area recon- naissance,the maintenanceof contaminationsituation maps, the posting.: of areas of hazard,and minimizingthe spread of contaminatedmaterial into uncontaminatedareas constitutethe activemeasures for reducingthe radio- logicalhazard,

C. - Personnelwithin an operationalradius of groundzero who are to be facing in the direction-ofthe flash will be requiredto wear special gog&es to protecttheir eyes against'excessivelight. Personnelwithin the ebove , operationalredius'who are not brovidedgoggles will face,.&h eyes closed, in the opptsitedirection from the flash, After ten (10) seconds,such personnel-mayturn about ~3 observethe phenomena.., ’

3. AnticipatedHazard Areas

a. Immediatelyunder the bomb burst there will be an area rf intense radioacitivityextending downward and to some'extentcrosswind and upind with gradual&rdecreasing intensityr.

b.: &tenting downwind,. (and to some extent crosswindand upwind) an air- borne radioactivehazard will exist. Its characteristicswill depend on the meterological5nfluencessuch as wind speed and-directionat various by altitudesup to.themaximum height raacheh the. cloud, c,' Contaminatedwater in the lagoon adjacentto the shot site may be of conseouence,and will be analyzedby the radiologicalsafety unit of TG 7.1 immediatelyafter'shot time end at otherintervals, *

d. Unless care is exercised,individuals or objectsentering contaminated areas may transferradioactivity to cleq areas& DNA e. By means ef instruments,such as Geiger-Muellercounters,ion chambers or ph&oelectricoellsit is possibleto. detect the area of contaminationand to measure the intensityof the radioactivity,Radiation intensity will. normallybe measured and reportedin roentgensper hour, Besidesthose

instruments,dosimeters pad film badges will bc used as indicatorsof the accumulatedexoosure to radioactivity.CkiLy personnel involved in work near, or in, radioactiveareas will wear film badges to providea permanent record of exposure,except for a few film badges issuedto units of TG 7.3 for an indicationof exposuresof personnelin the event that unit is caughtin llfall-outll.

f. The intensityof the radicactivehazard tends to decreasewith time due to decay of radioactivematerials, and dispersionand dilution,depend- ing upon climaticconditions, As an aoproximztion,the intensityof the radiationfrom the fissionproducts decreases by radioactivedecay inversely with the time after the detonation,

Appendix I to Annex J

I&d.L9&_oxContact ~,D~iopment Procedure EW.;E;I@KAtoll

1. General. The underwater detection system in use is, the Acoustic System Park 6 Nod 0, a passive listening device which receives underwater sounds in the audio frequency band. Fairs of hydrophanes are connected by submarine cable to the control equipment ashore. A line of hydrophones, spaced 300 to 350 yards apart, is located on the bottom across the Deep -trance and across the Wide Passage of ENIWEXOKAtoll. The rectangular area surrounding each pair is the approximate area in which that pair of hydrophones might be ex- pected to detect the presence of a submarine attempting to enter through the channel by stealth, These areas are numbered to correspond with the tactical numbers of the respective pairs of hydrophones, numbers one through three being looatzd in the Deep Entrance and numbers four through seventeen bzing located in the !Ede Passage. This system is not capable of discriminating between an underwater contact and a surface contact, nor positively between a large ship and a smaller craft. This requires that each contact via hydrophone be checked visually, if possible, or else by radar to ascertain whzther the suspected contact is a surfac e contact, and if on the surface, the type of contact. Becauseof the exwrimental nature of the SK 6 Hod C AcousticSystem, the contact reports indicatid in Annex J (Contact and IdentificationDevelop- _ ment Procedure) and based solely on I4K 6 Lad 0 AcousticSystcn indicationshall not bz sent to addresseesoutside of the Forwardiirea except by CTG 7.3.

2. Tasks :

a. TE 7.3.8.0 (Underwater Detection Xlemnt ) shall:

(1) Report suspectedcontacts by telephone,and/or radio on the harbor circuit2716 kcs, to CTU 7.3.8 and to CTZ 7.3.1.0 using the folloh;ingmessage system:

Thus, a message "MOG X0.G14 YELLO'::"would indicatean unidentifiedcontact at Station14. Follotingthis, a report of WX #Cc l4 IXT3" would indicate that the UnderwaterDetection Unit- station reportins contact on Station14 had definitelyidentified the contactas f&e or as friendly, b#'ermrerpossible, the UBU watch shall attemptto identifyall contactsby visual means prior to reportingas unidentified.

(2) Continuelistening to unidentifiedcontacts and ma'-eamplifying reports (usingcode below) until contactlost:
