1. IDENTIFICATION OF MISSlQli.

I

0.. Field Order No. 62, He0.4qunrwra XII Bomber cgp.iidij~;C;~dated 23 April 1945. directed the 73rd. 313th,:.Md Sl4.tb lIorl11'..... diN1lltt~~"ings to attnck an industrinl target in the Tokyo orea. onXXI Bomber CommandMission No. 96.

b. Targets Specifiedl

(1) PrimarY Target: Target 2009. the Hitachi Airoraf'tCompany Engine Works at To.chiknwa. WaSboth the primary visua.l and

radar to.rget.

(2) Second.,,,ry Target: The city of Shhuoka WOoS thesecondary target •.

(3) No last resort tnrget was specified.

2. STRATEGY N DPLAN OF OPERATIONS:

a. Reasons for Selectign of Tnuete This Commandwas com-

mi tted to strike Kyushu airfield insta.Uc.tions in support of the Oki-nawa invilsion. However, on 24 April the weather was unfavorable inthe Kyushu area and there wo.s a more favorable prediction for the TokyovicinitYI resulting in 0. decision to strike 0. ta.rget in the latter area.It was decided that the 3 Wings could each furnish 4 squadrons for theo.ttuck vnthout interfering with planned Kyushu nirfield strikes andmining operations of the Command. The Hitachi Aircraft Company ple.ntVIas selected bec ause it was a target of suitable size f')r the forceo.vo.ilable.

b. Importance of Target: The Hitachi Aircraft Company En-gine Works at Tachlkawa is a new plnnt whose buildings cover an areo.of o.pproxlmately 1,000,000 square feet. The production rate and typeof engine manui'a.ctured in the plant is not knovm; however, proximi tyof the factory to the large Tachikawc. Aircraft Assembly Plant suggestedt h c . t the flow of engines from the target might be to that outlet.

PhRT II - BOM3ARD IER 'S REPORT

1. The a1titu.de of o.ttllck varied from 10,000 to 14,500 feet,wi th the general nxts of atta.ck being 313 degrees true. The order0 .1 ' I:!.ttaok used wns ,as follows: the 73rd Wing was first into thetnrget, followed by the 313th and 314~h WIngs at 4-minute intervals.

2. The 73rd '1ing found 0. 01 BIlI' target. with CAVU Dondi tion, pre-vniling. Two of the 4 squadrons hit the target with bombs well cen-tered on the aiming point. In the lead Il.ircrrl't of the third squadron,a rack malfUnction caused its bombs to hang up over the target. as II .

result, it bombed the secondary target. The bombs of the fourth· a q u a -dron were off the tnrget due to fo.ul ty synohroni zatlon,

3. ¥.rt!,en the 313th '!.'ing attacked the primary target, it was part-l y obscured by ~l!loke. Three of t he squo.drons bombed into the smokeand the other squo..dron, as a result of faulty lde.ntification, hit tbewrong target, the TachikawC\. JdrcraftOempany,
