The forward 5" and 8" guns were unchanged and the forward superstructure was somewhat modified; the two funnels were trunked to one and the entire aft superstructure was replaced. Two Terrier launchers fitted aft in place of the original 5" and 8" guns. Two more Terrier launchers would have been added forward, but the missiles were rapidly outdated. Ships were obsolete by 1964; various proposals for limited modernization or complete reconstruction were not carried out. Both ships became CAs in 1968, with the 8" guns considered the main armament.
