(2) E n e m Y Antiaircraft c(a) Defenses:

,1. Tbere are 204 heavy guns in the Nagoya area.with apprO:Z:.imately100 of them concentrated in the dOClkarea. The la1;-ter group would be within effeotive range of the main farce at B-29'aon the planned route ani axis or attack.

_ g . Autanatic weapons defenses were not expectedto be effective at the recQllllDendedbase altitude of 7000 feet and lesseffective a t higher altitudes.1. Approx.imately 50 searchlights ",ere believedto be in the Nagoya area with an extension a1o118both sides at Nagoyaand Ise Beys to the south. Itwas estimated that cloud undercest amsmoke would decrease searehlight effectiveness.1l . There were no reports of barrage balloonsflying at the recommended base altitude. On a previous Nagoya mission

tnere had ceen 1 barrage balloon reported at an altitude of 6000 teet.(b) Recamnendations:

1. It lias recommended that aircraft attack franthe west on c eueaea of 80 to 90 degree_s true to avoid searchli~t def-enses and to bring aircraft under fire for the shortest time frem thesmallest number of guns. O n pz>eviousNagoya night miBsions. searchlightand flak effectiveness had increased liben aircraft approacbed from thesouth.

_ g . Aircraft were to fly directly to the Vicinityof Eiwa Lake to avoid the 'known antiaircraft defenses and were to turntowa.rd Nagoya at the lake. This would bring the B-29's within the ex-treme outer lilnits of the KYoto defenses, where only meager and inaccur-ate flak had been encountered ]reviously.

1. A slight breakaway to the northeast .. asrecommendetl after the attack in order to get aircraft ou~ of the baa.vyantiaircraft area and to avoid thermal activity. FollOliing the break-away, a course east. then southeast to Suruga -;ian 178S reemm nded toavoid Ta yohashi and H9.ni!3lIla.tsu ,

k. In .order to saturate the antiaircraft defensesand thereby reduce effective.ness, it lias reocm:nended that the attack becompressed into 1 hour .. 5 . . It was recoromended that IlircrG..ft desynchro-

nize 2 engines from th6 initial poi~t until the sti8rchlight defensehad been paaaed and that all e . ircrei't drop "rOpel (....:cdem)~. A quae s1t itude of 7000 fe&t w e . s r eaaunelld.e4 ...wi th aircraft of each 1iiing to be staggered within an 800-:foot bracket.
