Japanese aircraft carrier Shinano

Shinano (信濃), named after the ancient Shinano Province, was an aircraft carrier of the Imperial Japanese Navy during World War II. Initially laid down as the third of the Yamato-class battleships, Shinano's partially complete hull was converted to an aircraft carrier in 1942, midway through construction. Over the next two years, Shinano was heavily modified to act as a large support carrier. When completed, she had a full-load displacement of 72,000 long tons (73,000 t), the largest aircraft carrier ever built at the time.
