The Leonardo/Oto Melara 127 mm gun offers an ammunition range that helps explain choosing it alongside a 76 mm mount. Vulcano rounds form part of that capability. The stated reach of 120 kilometres and firing rate of 40 rounds per minute support a favorable assessment of its ability to deliver an effect at relatively low cost. It receives the strongest appraisal among the guns on the frigates considered, especially with Vulcano ammunition. Other available rounds also contribute to that judgment. Oto Melara's origins are traced to a joint venture involving Vickers and the Terni steelworks, connecting the modern weapon to an older industrial partnership.
