Albion had always regarded aircraft carriers as auxiliary forces in naval battles, specializing in long-range reconnaissance and harassment of the enemy during combat. They never expected that this fleet of flat-bottomed ships, built to vie with Charlemagne for a separate foothold, would play a decisive role in the struggle for sea control. Charlemagne's initial thoughts were not much different; aircraft carriers were built reluctantly, simply to exploit loopholes and compete with opponents—in an era where naval officers were staunch believers in battleship and big-gun doctrines, it was no easy task to propose and accept the concept of "full-deck offensive." At best, one would be viewed as a heretic; at worst, one would be dismissed from service.
