Larger carrier fleets expose differences in pilot replacement

More Japanese carriers could bring a Kido Butai-style force into existence earlier and give its air arm greater initial depth. Additional hulls would not, by themselves, repair the pilot-replacement system that limited Japan's ability to sustain wartime losses. Britain and the United States could also expand their carrier air groups while retaining their stronger replacement arrangements. For Britain, a larger armored carrier could combine the strike air group and protected fleet role that otherwise encouraged different designs. More exercises with carriers could expose weaknesses in fleet air defence sooner and encourage better anti-aircraft weapons and dual-purpose destroyer guns.
