The OTO 127/64 LW (light-weight) Gun assembly is a rapid-fire gun mount suitable for installation on large and medium size ships. It also has a version for coastal defense, intended for surface fire and naval gunfire support as main role and anti-aircraft fire as secondary role. The compactness of the gun feeding system makes installation on narrow section crafts possible.

The gun can fire all standard 127 mm (5 inch) ammunition including Vulcano long range guided ammunition. By that, it is officially branded as the OTO 127/64 LW - VULCANO System by Leonardo for marketing.

Modular automatic feeding magazines allow the firing of up to four different and immediately selectable types of ammunition; the magazines (four drums, each with one shell ready to fire and 13 other ammunitions on store) can be reloaded while the mount is in operation.

An ammunition manipulator system is available to transport projectiles and propelling charges from the main ammunition store to the feeding magazines, which are automatically reloaded. Ammunition flow is reversible. Rounds can be automatically unloaded from the gun. Digital and analog interfaces are available for connecting to a vessel's combat management system, including a CORBA based network interface.[4]

The 127/64 LW naval gun mounts includes a Vulcano module, which acts twofold:
