 Kaga was soon judged inferior to Akagi because of her slower speed, smaller flight deck (64 feet ( 19.5 m) shorter ), and problematic funnel arrangement. Because of Kaga's perceived limitations, she was given priority over Akagi for modernization. Kaga was relegated to reserve status on 20 October 1933 to begin a second major reconstruction, with an official start date of 25 June 1934.
