She operated in the Indian Ocean, and in the Dutch East Indies after the end of the war. In 1946 Queen Emma was returned to her owners and continued to operate as ferry from the Hook of Holland until 1969, when she was scrapped in Antwerp, Belgium.

The first ship to be completed, HMS Vindictive, was renamed from HMS Cavendish and converted into an aircraft carrier while under construction. All ships were named after Elizabethan sea captains. The three ships remaining as cruisers in 1939 served in the Second World War, with Effingham being an early war loss through wreck; Raleigh had been lost in a similar shipwreck on uncharted rocks in 1922. Vindictive, though no longer a cruiser, also served throughout the War. This class formed the basis for the definition of the maximum cruiser type under the Washington Naval Treaty of 1922.

The following year she participated in the British campaign in the Baltic against the Bolsheviks, during which her aircraft made numerous attacks against the naval base at Kronstadt. Vindictive returned home at the end of the year and was placed in reserve for several years before her flight decks were removed and she was reconverted back into a cruiser. The ship retained her aircraft hangar and conducted trials with an aircraft catapult before she was sent to the China Station in 1926. A year after her return in 1928, she was again placed in reserve.
