As these achievements indicate, / the Japanese started the war aware of the fact / that major offensive action cannot be undertaken without local control of the air. / They also appreciated the vulnerability to air attack of surface objectives,/both on land and at sea. / The Japanese failed, however, / to appreciate the full scope and complexity of the requirements / for continuing control of the air. / The Japanese aircraft production program at the start of the war was inadequate, / as the Japanese subsequently discovered, / not only in relation to that of the United States, / but even in relation to the capabilities of their own economy. / Their planning and execution with respect to / training, maintenance, logistics, technical development, intelligence / and full coordination with their land and surface forces, / were limited in relation to the requirements that subsequently developed. / Japan’ s war plans did not contemplate,./nor were its capabilities such that it could have contemplated, / interference with the sustaining resources of United States air power.
