Leonardo's OTO 127/64 LightWeight (LW) Vulcano naval defence systems have been selected by Damen to equip the German Navy's new four F126 frigates, with the addition of two optional vessels. In addition, the contract includes the supply of support for maintenance activities, simulators for crew training, and onboard activities for the integration and commissioning of the system. 

The OTO 127/64 LW Vulcano naval gun is a technologically sophisticated and fully digitalized system able to provide constant support to operators and the onboard Combat Management System for the calculation of shooting solutions during mission planning. Unique in the international marketplace, Leonardo's 127/64 LW Vulcano gun can employ equally the standard ammunition 127mm and both variants of the company's Vulcano 127mm ammunition: Guided Long Range (GLR) and Ballistic Extended Range (BER). The gun extends a naval unit's defensive capability up to 85 km while maintaining precision accuracy.
