The Otobreda 127mm/54 Compact (127/54C) gun is a dual purpose naval artillery piece built by the Italian company Oto Melara. It uses the 127mm round which is also used in the 5 inch/ 54 gun, albeit that this gun calibre is measured in imperial measurements rather then metric. The gun uses an automatic loading system where 66 127mm rounds of various kinds can be stored ready-to-fire in three loader drums (each holding 22 rounds). The barrel is water-cooled. Currently the gun is still in use by navies around the world but it is slowly being replaced by the Otobreda 127/64 for new vessels, of which the German Navy F-125 class frigate and Italian Navy FREMM

A replacement of the 127/54 compact, Oto Melara started the design in 1992, and completed in 2003[1] The new lightweight gun, weighing 17 tons without magazine or ammunition handling has a rate of fire of 35rpm.
