Political limits behind carrier design choices

A longer Implacable may have been the Royal Navy's preferred choice, with the selected design closer to option B. That is an inference from wider experience of naval design studies, rather than a firm identification of this ship's rejected option A. British studies often moved toward options B, C, or D under the government of the day. The comparison with interwar Japan suggests that fear of political violence discouraged politicians from challenging naval preferences. Political constraints helped determine which designs could be approved.
