The history of the large-scale military campaigns of the Imperial Navy began with the 1895 Sino-Japanese War and the 1905 Russo-Japanese War ended with the Imperial Navy's near perfect victory; however, in the Great East Asian War (the Pacific War) the fighting power of the fleets of the Imperial Navy was almost completely annihilated by the United States Navy and the Imperial Navy was officially dissolved at the end of the war.
