(c) If the Japanese had been successful in eliminating substantially all air opposition in the above areas and were not faced with strong air opposition from other Islands in the Netherlands East Indies, the scale of attack might reach some 400 450 aircraft. The Japanese might reinforce the above forces by aircraft operating from aircraft carriers and seaplane carriers to a total of some 100 150 aircraft. These could operate from the Gulf of Saigon against Lower Burma. Submarines will probably be used against our forces operating in the Bay of Bengal.
