To ensure the absolute success of Australasia's amphibious landing operation, before launching the attack, the General Staff had decided to conduct another massive bombing on the Island Nation's native military bases and navy harbors.
The purpose of this bombing was to completely eliminate the aerial and naval threats from the Island Nation on their homeland, turning the landing operation into a war between the armies of the two countries.
Thus, annihilating the Island Royal Navy became a necessary task. Earlier bombings on the native land of the Island Nation had already caused tremendous casualties to the Island Nation Army's air force, reducing it to a mere tenth of its former size, no longer posing any threat to the Australasian Air Force.
However, the Island Royal Navy, by holing up in Hiroshima's harbor, had so far not suffered overly heavy blows.
