The BAE Systems 57 mm gun and OTO Melara 76 mm are the leading options in this size band. The Royal Navy's choice of the 57 mm for Type 31 is attributed partly to BAE being the British supplier. A preferred alternative would mount three 76 mm guns, creating a much harder obstacle to overcome. The comparison connects an otherwise credible gun choice to the industrial relationships behind procurement.
