Did other navies independently reach the armoured carrier?

Were Taiho and the Midway class copies of British thinking, or did Japan and the United States develop protected carriers independently?

All three navies explored the concept, but Britain's expected theatres made a protected carrier especially compelling and shaped how it was used.

Jamie notes that Japan and the United States also studied armoured carriers before the war, challenging a simple story of copying Britain. Alex accepts the shared technical exploration but argues that Britain's Mediterranean exposure and global repair problem made protection an immediate operational requirement. He questions whether American and Japanese planning gave enough attention to the damage carriers would carry into operations after the expected major battle. Jamie agrees that the concept depended on victory. Later comparisons with the Midway class connect protection to operational use, while leaving room to question exaggerated claims about British survivability.
