The Un Ited states Strateg lc Bombng Survey

was established by the Secretary of War on 3

November 19~~, pursuant to a Directive fromthe late President Koosevelt. Its mission

was to conduct an impartial and expert study

of the ef f ec t s of our aerial attack on

Germany, to be used in connection with air

attacks on Japan and to establish a basis

for evaluating the importance and potentiali-

tiesofair powerasan instrument of military

strategy, forplanning the future development

of the Vnited States armed forces, and for

determining future economic policies with

respect to the national defense. A summary

report and some 200 supporting reports con-

taining the findings of the Survey in Germany

have been publ l shed,

On 15 August 19~5, Presid~nt Truman re-

quested that the Survey conduct a similarstudy of the effects of all types of air

attack in the war against Japan, submitting

repo rts in dup I icate to th e Sec retary of

\o,ar and to the Secretary of the Havy, The

officers of the Survey during its Japanese

phase were:

Franklin O'Olier, Chairman.

Paul H. Mitze,

. The Survey's como l ement provided for 3CO

civil l an s, 350 officers, and 500 enl isted

men. The mil i tary segment of the 0 rgan izat ion

was drawn from the A.rmy to the extent of 6G

per cent, and from the Navy to the extent of

ijO per cent. Both the Army and the Navy gave

the Survey all possible assistance in fur-

nishing men, supplies, transport and infor-

mat ion. The Survey operated from headqua rt er s

establ ished in Tokyo early in Septell'ber,

1945, with sub-headquarters in Nagoya, Osaka,Hiroshima and Nagasaki, and with mobile teams

operat jng in other parts of Japan, the islands

of the Pacific, and the Asiatic mainland.

I twas poss ib I e to recon st ruct much of war-

timeJapanesemil itary planning and execution,

engagement by engagement and campaign by

campaign, and to secure reasonably accurate

stat i st ics on Japan's economy and war-pro-

duction, plant by plant and industry by

industry. In addition, studieswereconducted

on Japan's overall strategic plans and the

background of her entry into the war, the

internal discussionsandnegotiations leading

to her acceptance of uncond it i ona I sur render,

the course of health and morale among the

civilian po pu l at ion, the effectiveness of

the Japanese c i v iii an detense organ i zat ion,

and the effects of the atomic bombs. Separatereports wil I be issued covering each ~hase

of the stuoy.
