The “Dido” class is a failed attempt to reconcile anti-aircraft and anti-ship capabilities to respond to destroyers. In some ways, they can be compared to “super-destroyers” and they follow the same approach as the Atlanta Americans. This mixed capability was based entirely on the new secondary casings developed for the King George V class battleships, twin 133 mm mountings. Relatively light, these could be divided into a triple tiering in the front. However, in use these guns proved too slow to fight effectively against aviation, and too light to deal with enemy ships. 11 ships will be started in 1937-39, launched in 1939-41 and completed in 1940 (Dido, Bonaventure, Naiad, Phoebe), 1941 (Cleopatra, Charybdis, Euryalus, Hermione) and 1942 (Scylla, Sirius, Argonaut). Their armament was so inefficient that it was decided to modify the Scylla and Charybdis still under construction by giving them four 114 mm double hulls.

These units were used extensively despite their defects, and 4 castings: The Charybdis was sunk in 1943 by the German torpedo boats T27 and T23, the Bonaventure by the submarine Italian Ambra on March 31, 1941, the Hermione and the Naiad by the U-Bootes U-205 and U-565 in 1942. Virtually all others suffered damage from torpedoing but survived. In June 1944, the Scylla jumped on a mine, was rescued, towed, but never completely repaired. Their DCA was increased in 1944-45 by 20 and 40 mm pieces in single carriages, and they were removed from service in the 1950s.
