Japanese aircraft carrier "Kaga". She was initially being built as a
battleship, but as a result of a coincidence she became one of the first
large carriers in history. She was a part of Japanese Kidō Butai, a
group of carriers that decided about the power of the Imperial Japanese
Navy during the first half-year of the war in Pacific. After a daring
attack on Pearl Harbor followed by a series of further victories there
was a reversal during the battle of Midway, when "Kaga" and three
accompanying carriers were destroyed which ultimately buried Japan's
chances for winning the war.
