The '''Otobreda 127mm/54 Compact''' (''127/54C'') gun is a [[naval artillery]] piece built by the [[Italy|Italian]] company [[Oto Melara]]. The gun is completely new but uses the same semi fixed ammunition as the American [[5"/54 caliber Mark 45 gun|5 inch/ 54 gun]]. It was introduced into service in 1968. A new advanced lightweight mounting for corvettes has been developed. The barrel is water cooled. Currently the [[Otobreda 127/64]] with a longer range and less weight is being developed. This new model will first be mounted on [[Germany|German]] and Italian warships.

It uses the 127mm round which is also used in the 5 inch/ 54 gun, albeit that this gun calibre is measured in United States customary units rather than 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, such as the German Navy's F125-class frigate and Italian Navy's FREMM.
