Service The Arethusas proved to be very satisfactory in service, and their hull was adapted for the of 1937. All had a very active war, especially in the Mediterranean; the two that were lost were torpedoed while working close inshore. Arethusa had a narrow escape in November 1942 when she was hit by an air-dropped torpedo. She caught fire, had two of her three turrets out of action and was badly flooded. However, she survived to be repaired at Charleston in the United States. Ships See also List of ship classes of the Second World War References Cruiser classes Ship classes of the Royal Navy
