D-class cruiser armament and wartime refits

The D class followed the Carlisle-class pattern with longer hulls for an additional gun mounting. Each ship carried six six-inch guns and twelve torpedo tubes in four triple launchers. Lessons from Jutland brought more deck protection over the magazines and better gun shields. Wartime updates were generally limited to extra light anti-aircraft guns and radar, since ships serving away from the Home and Mediterranean fleets received fewer regular upgrades. Dunedin was torpedoed and sunk off Brazil before any major armament changes could be made. Delhi was the exception: a 1941 refit in the United States replaced her main battery with five American five-inch guns, Mark 37 directors, and fire-control radar.
