HMS Belfast and short-range drone defence

Would a fully functioning 1960s HMS Belfast be more or less effective against drones than a modern air-defence destroyer?

A Belfast restored to her 1960s armament could provide useful short-range fire against drones.

The proposed Belfast is the 1960s version with its 40 mm guns and other armament fully functioning. That battery could be useful against drones at short range. The comparison questions whether modern frigates and destroyers have concentrated too heavily on avoiding detection while allowing their defensive firepower to diminish. The claim concerns short-range gunfire, with no overall equivalence to a modern air-defence destroyer established.
