In October 1940, she conducted Operation Medium, an attack on German transport ships that had been collected along the English Channel in preparation for the since-cancelled invasion of Britain. "Revenge" thereafter resumed convoy escort duties until October 1941, when she was reassigned to the 3rd Battle Squadron and sent to the Far East as tensions with Japan began to rise. British naval forces were strengthened further after the start of the Pacific War in December, leading to the creation of the Eastern Fleet. "Revenge" and her sister ships were deemed too old to be of use against the Japanese fleet, so they were relegated to convoy escort duties in the Indian Ocean. Badly worn out by 1943, "Revenge" returned home, where she was removed from front-line service. Her last voyage was to carry Prime Minister Winston Churchill to the Tehran Conference in November 1943. Upon returning, she was assigned to the training establishment , disarmed, and eventually broken up in 1948.
