The Oto Melara 127/64 Lightweight (LW) naval gun mount is a rapid fire gun mount suitable for installation on large and medium size ships, 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 possible the installation on narrow section crafts.
The gun can fire all standard 127 mm (5 inch) ammunition including the new Vulcano long range guided ammunition.
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 any Combat Management System, also according to COBRA[disambiguation needed] protocol.
The 127/64 LW naval gun mounts includes a Vulcano module, which acts twofold:
- Programmer for ammunition's fuse and guidance system
- Mission Planning and Execution for Naval Fire Support Action (firing solutions, selection of ammunition, definition of trajectories and firing sequences, ballistic computations accounting for ammunition type, etc.), as a standalone or in interaction with ship's Network Centric System
- on FREMM GP class frigates (2 127/64 in service and 4 ordered)
- on PPA frigates (7 ordered, 3 on option, 6 planned)
