Tactical Mission Report which combines ]Hssions Number 303. :310 and

:315 executed by that Wing.

2. MISSIONPLANNING:

a. Selection of Tar,ets: The remaii1der of the 160 Japanese

Sl:lall urban industrial cities marked for attack that had not been bombed

successfully on previol:ls strikes were considered in the selection of

the targets for these missions. Selection of these cities for o.ttnck -ccn-.1:'Ol'1le(: to the easiG requirements of having adequa",-e radar scope photos,

target il<ltel1igel'lce al'ld reconnaissance 0f target areas,

b. Importance of Tarset§:

(1) The City of Hachioji is located in a mountainous Area

23.miles west of the Tokyo Imperial F~lacq. It controls all of the Tokyo

ra11 ~raff1C to the northern half of Honshu. Eachioji is a housing area

for V tal outlyi~g districts and although its own industries formerlyVletrec0nnected wlth textile manufacturing, war tir oduct.Lon is now be tnge ressed, •

-1-

(2) Toyama. the third largest city OR the west coast of

Honsbu, is located inland from TOYaJIlaBay, 5 miles south of the Jinsu

River port of Higas,hi-Iwase and 110 miles nc rbh of Nagoya. The city

is an ii'1}:lortant producer of ball 8.11(\ roller be ar Lngs, machine and pre-

oisi00 tools and special steel products. A magnesium plant along w i t h

the largest aluminum company in Japan is loc ate d there. Toyama is not

compact. being cut by several canals.

(3) Nagaoka. a city of 70,000 p"'pulation, is located

in north central Honshu. 35 miles south of .~ii.:;ata and 12 miles from

the shore of the Japan Sea. Nagaoka is a roa.il and service center for

the surrounding oil fields and an important pr-oduce r of machine and

i;lachine tool products.

(4) r.iito is located 60 miles nor'~heast of Tokyo on the

bal'll:: of the Na,kaRiver and 7 miles inland fron the Faciric Ocean.

;1i to is t.he main s ervlee center of the Johan Rail road and its urban

area is a source of labor supply and a cent.e r of sub-contracting for

rr e arby high-p riori ty Hitachi pI ants.

c. Time F.ctors;

(1) SeLe ction of D-Day was dep6mlent on weathe r eondi-

t.ions over the target areas.

(2) Selection of the target ti:ne waS based on favorabledaylight take-offs and landings,

~. Qj.scupsiop: The target area was primarily

of light, highly inflammable construction. and waS considered ideal for-

Iltt;:;.ck with the M47 end M69 incendiary bombs, Iiixed loads of 1/2 ~47

incendiary bombs and 1/2 E46 incendiary cLuste r s containing !f.69 bombs,

with each aircraft to carry 1 47 white phosphorous bomb, were specified

to increase total tonnage and to equa lLz.e talee-off wei'ghts of all air-

craft. The M47 white phosporous bombs wer-a to be carried for the same

reasons as in Missions Number 306, 307, and 308. The above were selected

to give a maximumuniform density, proper penetration and efficient

functioning of both bombs and clusters,

The approach was to be cross wind to avoid h~nt thermals on th_ bomb

run, and to obtain maximumr esuIts from the large do.flection errors

v/hich were expected to be obtained by app r-cuchfng the; city on an axis

perpendicular to the length of the target.

for these urban targets. ElectroniC jammers Viers to be installed in

each s tr ice aircraft to barrage jam the 72 to 84. and the 190 to 210

megacycle regions. Spot jammers were to be employed to jam any sear ch-

light or gun-laying radars appearing outside tho barrage. Rope WaS to

cycles Wtls to be continued and enemy communications we r-e to be recorded,

(4) Flak Factors:

(a) Hnchioi!: The target is within the Tachikllwa.

defense area. within which there is n total of 30 heavy guns. 6 of which

were located at Huchioji. Five to 10 searchlights should be effective

on thG planned app ronoh to target. !l1ediumflak should be ineffective at

the pI nnne d a l ti tude of 15,000 feet. and due to the poor searchl ight

defense generally meager and inaccurate heavy f'Lak was expected. The

approac h from the southwest would bring the o.ircro.ft within range of

the Numozu poor night defenses which included 2 sco.rchlights, 8 heavy

guns plus 12 (probo.blos) heavy, Route to land's end and 11 breakaway to

the northwest were planned to avoid large fLak concentrations.

(b) ~ : No seuFchlights had be en n ete d in thist::vget area, but 10 heo.vy antiaircraft guns were expected in the Toyama.

ar ea, However, it Was believed aircr •.ft would be barely within r-ange

on the planned axis o f: uttack; and br enknway , iliedi4m WGupons should be

ineffective at the planned altitude of attc.ck. 12,00C feet.

(c) Nagaeka; No defenses WGN expected in this ur ea ,the route 'd' ~'fUVOl lng ~l lak" except 2 heavy guns at Toyama. At the

planned nttac~ altitude of 12,000 feet only meager an d inuccurute flokwas ant 10 ipute d.

(d) Mito: There 'were 18 heQV'Jguns and 3 search-

lights in this area. but this Was considered a weak defense Genero.llyme~g0r d' •t: o.a lnaccurate flak was expeoted at the ~lQnned altitude of

Q ~Qck. 12.000 feot. Medium weapons should pro;c ineffective.

(5) Assembly Points: Bombing WaS to be done by individualai:rcl':lft. with nc

o assemblies to be effected.

(3) Menn Points of Imn.n.ct: (See 1;eun Points of Impact,

Annex A, Part II), The alming points were to va.ry with euc h target as

follows;(n) Hnchioii: A mean point of impact waS selected

northwest of the railroad yards near the center of the city. A probable

circular error of 4000 feet weu1d include virtuo.lly ell of the city_

(b) Toynmo.: Amean point of impo.ct was selected at

the southeast edge of the Castle, with a probable circular error of

4000 f0ct. tho.t inCluded nea.rly 0.11 of the original c1 ty.

(c) Na.g.e.oko.: A mean point of impllct was selected neur

the cente r of the city. with a prObable circul Ill' error of 4.000 feet whic'I

included most ¢f the built-up urea.

(d) Mito: Two mean points of impact were selected,

1ncar the center of the densely built-up west cnd :londthe other near

corrter of the east end. with probable circub.r errors of ,,·000 feet on

the west end 2000 feet o n the east covering m o s t of tho city.

g. Defensive~ Tae.tics::

(1) EnCJmyFio1:hter Re",ction: Tho 8.29' s striking at Hnchioji

and Hito might be intercepted by 40 to 50 fighters. 'IIith most of the

opposition coming at Hachioji. At ~'i.to, 10 to 15 enemy fighters froll)

the Tokyo area might intercept, the attacks pr obnbLy occurring from land.

fnll to tho target. bGco.use at that point a right turn wo.s to be made

to get over water. Opposf tion at Toyama and Nagaoka VIas expeoted to be

nil to negligible. but interception might be made by 20 to 30 enemy

fighters, with a possibility ef 5 to 10 of tho int0rceptol'S being meten route between Osaka and Nagoya. Aircraft o.ttacking Nagaokn Vlere

expected to meet little or no opposition on withdrawal. but B-29's strik-

ing Toyruno.might meet 15 to 20 twin-engine fighters near 1and , s end east

of Hamnmat.su, The plann:Lng was predicated on the probabili ty that Jo.po.-

nose fighter intercept.ion would continuo to rema i.n weak and ineffective,

but it Was difficult to predict exo.ctly when t~crc might be a substantial

z-esurgenc e of enemy fighter defense.

;1. Summarv:

f

I

!l. Fighter opposition was slight on this series of 4 night

incendiary mssions to HaChioji, Toyama, Nagaoka. ClndMito. ).pproximntely

105 to 130 enemy fighters 'I.ere a.irborne. the greatest. number airborne

against a series of Superfort strikes in 2 months. However, only 12

attncks were mnde o,ginst the B-29 att",c.k.ing forces.

b. The sm al I number of at.t acks in vi~w of the large nomber

of fighters that were airborne! would seem to indict.te that the Jo.pa.-

ncse purp oaeIy avoided cont acc with the B-29's or that the fighter

pilots Vl",re inexperienced. Night strike.s -in this area 4 . - 5 months

ago ordinarily sustained 2 5 - 1 00 attacks from a similar number of

interceptors.

c, Many 01 ' the interceptGl's that. -were a.irborne m~ have

opposed both forcGs of B . a s -Is striR:ing at Ko"wo.sskiand Ha.chioj1.

The fighters that opposed the Mite raiders were not believed to have

entered the Kawasaki and Hachioji target arGas.

d. No B-29 waS lost to enemy fighters. nnd only 1 suffered

minot: dClJDaf;edrom fighter fire; no claims '{rorc made by B.29 craws.

2. :Mission Number 306, __Hll,chioii, 58th \1in!;:
