    (2) The Ube Coal Liquef!'lotion Company (Mission Number283) is credited witb the espf.ci.ty to ~od uee 475,000,barrei~ ':~ :~~:ethet io 0il, about 1/3 of J(:lpanes e home~)_sland llroduet lODG .).. .to its raw mat erial source, probablY 0bta ining coal Ir em th e und er1;;eamines apprOJl;imately 1 mile to the s,outh~ It is, therefore, ,8 mostimportant target in synthetic oil production. Its destruetl.on \"1oulafurther com];)ieate the enemy r S already over burd ened oil pro bl em.

    (3) The 3 targets (90017~11{' \' 90.17-127 ~ 90 "17-13)Which make up the petroleum complex to be attacked on Miss~on Nwr,bcr,291,together I are credited with almost 25 per cent of central Japan scrude oil refining capoci ty and 20 per cent of' its storage capacity,.

    e. Ti.me Faetors: .il.sde fr om the pol icy of conducti ng at tacksby the, 315th I,illg at night. time factors were of little impo.rta nee inthe planning of these missions.

    d. Wrunitions and Fuel Loading:(1) Sle ct ion of Bombs and Fuzes ~ The Soo-paund general-

    purpose bombwas selected for use against a11 3 targets.~ The NipponOil Company (Miss.ion Number 270) and. the Petroleum Oomplex (MissionNumber 291) contain installations of both storage and refio8J:Y tYl)e,against which the large number of hits obtainable by the use of th:;'ssize bomb should result in maximumdamage to both rr:e.nUfacturing andstorage facilities~ The Ube Coal Liquefe.etion Oempany (Mission Number283) contains buildings of reinforced concrete and wood frame type,all of which are srrall in plan area. The use of larg.er si'Z.e bombswould prove roost effective against the concrete structures, but \'Iouldnot permit maximumtonnage to be carried andwo~ld elso decrease thenumber of dixect hits 0 Itwasbe1 ieverft, in selec.t ing the SOO-poundbomb, that this bombwould b capable G lf destroying the wood framestruc'tures and also i'ilo1)lldseriously damage the reinf'orc.ed installat-ions. Fuzings of .1-second delay nose 'I1er~ selected for the bcmbs tobe employed on all 3 targets & This delay fuze was selected as anassurance fuzing only. since nose fuzes with shorter delays were notavailable.. Tail fuzings of ,,01 second delay fqr Mission NUmber 270and 283 and ".025-5612000. delay fer Mission hbcr 291 were selected ..The .Ol-second and g025-second delay tail fuzes were selected sincethey would allow sufficint pe.netration of the bombwithin the. in-stallations in each case, to 11depth a.ssuring maximumdawllg80

    (2) BombLoading: It was estimated that approximately18,,500 pounds of bombs per aircraft would be ,carried on these missions 0

    (3) .l:cnunition Loading~ Itwas, estimated that 600 roundsof ammunition per aircraft would be carried.

    (4 ) Fuel Load.ing: An ?J:vertlge f'uel load per aircraft of6.500 ga.llons \'Il8S estimated.e. Flight Planning:

    (a) Mission Number 270: Radar navi,z8t ion "as .ex-. '.pected to be very good on this mission because Of ~he, exc~l1Jllt..coast.cllcheck points of Kyushu and Shikokue !;mdfall, a dJ.stl-r:ctJ.~e po~n,,: onthe 00utbwestern tip of Shikoku was expected to be_ea,slly J.dent~f J.edby radar operators .in time to makethe initial wind ru~o The dJ.s,,:e~ce:from landfall to the initial point, 77 miles, was cons;tdered suffl.C l.entfor recheeki'ng wind and ground speed because of the 1and-1ilstcr "C~Iltrastwhich 'would facilitate n;:Ivigotion end identification of the 101t181point. The run from the initial point to the target has aomc goodcheek pointsOI.nd drift was not expected to exceed '6 . degrees ~ The-targetitself was.,~pect;ed to be easHy id.en:tified~' slace "it, was ,9],tuated d1TJ-ectly Dn.a _ptomineRt c~st 1iDe~', It; wacSplanl'l.edto emIll:JYdiract radarsynchron0us bombing on this target ~(b) Mission Number 28'1: Landfall ~ a prominentpenins.ula on the southwest coast of Shikciku, was expected to beeG s ily ident'i,fied 'by radar. It was believed that the use of theislands and the peninsular 003St line of the Inland Sea would fac-i!ta te radar nav iga t ion. The ini tie 1 point, Hirne Jima, T I E l . s crpec t,edto be dBsily p:"cked up by rad.sr and should provide a good run to thetarget. It was bel h:ved that the course from l'andfall to target 9 whichapproximates a straight lins, would allew tbe radar operator ample timefor computing all important data. T"hetarget, located on a coastalprojection just north of the city of Ube, would be resolved Q.S a sep-arate return. It was planned to employ a direct radar synchronousrelease on this target ..

    (c) Mission NUmber291: Landfall point, Ioeated onthe sQuther'n tip of'the arrowhead .shaped peninsula south of Mount Fuji,was expected. to be easily identified by all operators at a range ofapprOXimately 50 tl8utical miles. Itwas .believed. that lQ1ldfall pointwould be a gQod.wind point to em);lloy in making the radar wind run" Thecourse from landfall to target approximates a straight line and the in-itial point provides a very good coastal cheekpoint. The area in T.":biehthe 3 targets of the complex is contained, is, a series of square patch.sof reclaimed land separated. by canals. The .'I.}.'Q...7 radar equipnent re-solves these ar-eas so' that the operator \'Iould be able to determine theexact target Locafion. ';Ii th a straight eour se from Ie ndfall to thetarget, itwas expeeted that each aircraft could check the ground. speedand dr ift for" bombrelease. It was planned t a employ 0 . irect radarsynchronous bombing on this target.

    (3) Antiaircraft Fae tQI"S :(a) Mission Number 270: There Were 16 heavy guns.

    20 medium guns, and. 3 senrchlights located in the RiJ.d.3matsudraa 0 Thiswas considered a v.ery weak d.efense Qgainst night attack and only meagerand inaccurate flak was expected. Medium flax wou'Id have little effecta.t the planned 81titucles of 10,000 to 11,000 feet. The route was plunned.to avoid other antiaircraft co,nce.ntrati(lns and the axis of attaek would8TOid the 34 heavy guns loceted at nearby TokuYQJ] }E l .
