Why were the last planned Tribal-class destroyers cancelled?
Short answerThe Battle class was considered a better wartime design because its 4.5-inch armament offered more useful dual-purpose fire, with the Daring class following later.
NotesThe end of Tribal production reflected changing wartime requirements rather than rejection of the class's record. Air attack had made high-angle, dual-purpose fire increasingly important. The Battle class was judged the better wartime design because its 4.5-inch battery answered that requirement more effectively. The Daring class then carried the gun-destroyer line forward after the war.
