High muzzle velocity also raises questions about barrel length and the wear a navy is prepared to accept. Japan expected to fight in the Pacific with access to home infrastructure and industry. In theory, that allowed more demanding maintenance than Britain could accept while preparing to fight Japan on the other side of the world. British equipment needed to remain effective while being as easy as possible to replace, repair, and maintain on distant stations.

Gun performance, barrel wear, and distance from home industry
Japanese and British deployment plans created different limits on the maintenance burden their naval guns could impose.
