The "Bellona" subclass differed in appearance somewhat from their predecessors. They had eight 5.25-inch RP10 MkII guns in four twin turrets and had greatly improved anti-aircraft armament, with twelve 2-pounder guns and twelve Oerlikon 20 mm cannons. The bridge of the "Bellona" class was lowered by one deck compared to the previous three groups, which allowed full radar control to be fitted to the 5.25-inch turrets and 2-pounder guns, due to the decreased topweight. These ships used the HACS high angle fire control system. The two funnels were more upright than the raked ones of the original "Dido" class.
