You can put as many 5.25" Mk.I turrets and HACS on Hawkins as you like and you will still not achieve a decent AA cruiser that's worth 9,500 tons. The truth is, the Mk.Is were designed to defend against straight-flying, high-evel bombers approaching on a predictabe course and height. The 5.25s were very much useless against faster and more maneuverable aerial attackers. In fact the whole of the 16 Dido and Bellona class cruisers only shot down 15 enemy aircraft during the war. Meanwhile, the converted AA cruiser HMS Carlisle, re-armed with 4x2 - 4-inch AA guns, accounted for 11 enemy aircraft.
Only exception was HMS Scylla of course, but she was armed with 4.5" twins
