2. STR lTEGY &illD PLAN OF OPERATION:a. StrategY:(1) Weather we.s the deciding faetor in the seleetion ot

another series of cities for night incendiary attacks. Planning ofthe missionm was similar to that of other Bomber Ccmnand ~trikes in.which 'iiings were assigned separate cities to be attacked at ni8ht,employing the radar method ot bombng.

bQ Impo~tanee ot Targets:(1) Xure Urban ~ (Mission 240) ~ Kure is one ? f t hemos t impor tant t ar get conce nt rat ions on the Inland Sea. The C1tyhouAesworkers of the great Xure Naval Base dnd has a lJopulatioB of2 7 5 . 00 0 with a population density of over 70,000 per squar e .mile.The city proper measures about l!- miles Nort and 1 llIl.~e

Eaat-~e5t., A fe~ emall industries are located in the city but thelarger and more im~ortant installations are out of the congested area.drailroad station and some warehouses on an alternate of the san-Yoline are located at the Southwest edge of the eity.(2) KwjlamotoUrban ~ (Mission 241) t K\lJ1lamotosthe fourth' largest city on. K;yul!lhu.,It contains a number of SJ:!lallindustries. many of which probably are converted to the manUfacture

of aircraft parts for the assembly plant lt miles east of the city.It also Q:)ntains large military installations and important railroads.The ci ty is about 3miles Northeast-Southwest and 2 mil6$ Northl1est-Southeast.. The Shira River enters Kt.unlan.otorom the northeast anddivides the city apprOximately in halt, forming an effective firebreakabout 400 feet wide. A castle and military headquarters area are imthe north'1est section of the ci ty.(.3) .~ ~ Area,'(Mission 242): Ube is a city otapprOXimately 100,.000 population. the largest on Southl:;est Honshu.It has several important targets in JapaLlese wa f production. inclUd-ing the largest single magnesium plant in Japan.., and third largestnitrogen fixation, plant. an important coal liquefaction. plant pr0.-duc i.ng synthetic oil. the largest steam power plant in SouthwestHonshu and a n1J:rnberof small steel and oil plants..

of the preponderant proportion of the fighters to an anticipated in-va~o~ Another controlling factor was also the apparent shortage ofaViLatlOn gasoline. Although the Japanese have night fighters they arefew in number and their equipment is far below that of Allied standards.F~r that reason interception by night fighters and night tighter-dayflghter combinatioIlB will remain weak. Moat of the interception il'il1p7'0bably occur in the target area where B-29s wUl be silhouetted byflres or by searchlights. There is nothing to indi cats that the enem;y-mil employ neu tactics and it can be assumed that the enenl will beable to warn his defenses from 3 to 5 hours prior to B-29 landfall andthat,there will be interceptors to meet bomber formations approximately50 mlles out to sea. T he diversity of the targets and poor operationalweather may reduce the anticipated fighter reaction indicated above.

Fifty eight airoraft landed at Iwo Jima dUrlZl8 these missi.ons.f. Losses; OneB-29 was lost when 2 engines failed enrouteto target an d 1was lost when the ailerons froze.g. Operat ions Sumnary:

(l) NaVigation (See Annex A, Part I. for track chart):Tnere were no major n av ig at io na l di sc re pa nc ie s noted but time controlwas not as good as that on previous missi ona, Winds in the varioustarget areas varied from .300 to 320 degt;'ees at 30 to 25 knots respect-ively .

(a) Narrative of Mission as Flown~1.. Cruise to the Mainland: Individual climbs

'Were made immediately aifter take off to altitudes betrreen 4. 00 and8,000 feet where taG initial cruise was flown. N o assemblies : r e rem ade ., C om pr es si on . of the forces was effected by varying c r UiSlngaltitudes and air speeds .

g. Bomb Run: Bombing was conducted by indiv-idual aircraft at 10.000 feet average for the 58th. 7Jrd and 31J1;h Wingsand 14.000 feet far the 314th Vling.

1. Return to Base: Return to base was conduoldby individual aircraft without difficUlty. Minimumfuel 178.9 used l '>ycruising at 15.000 feet for two hours, descending very slowly to 9.000feet am cr.uising there till a 180 rpm descent could be made to base.185 C.A.S. was flown.
