The Oto Melara 76 mm gun is a widely used naval artillery piece built by the Italian company Otobreda and Oto Melara. A tank-mounted version known as the Otomatic was built for the SPAAG role, although this was not put into production.
It is capable of very high rates of fire, making it suitable for short-range anti-missile point defence. Its calibre also gives it abilities for anti-aircraft, anti-surface and ground shelling. Specialised ammunition is available for armour piercing, incendiary, directed fragmentation, etc. A new stealth cupola has been designed in recent years.
The system is compact enough to be installed on relatively small warships, like corvettes, avisos, or patrol boats. It is a successful matériel in export, in use in 53 navies.
It has recently been favoured over the French 100 mm naval gun for the new Horizon CNGF frigates.
On 27 September 2006 Iran announced it has started mass production of a marine artillery gun, named the Fajr-27, which is a reverse-engineered Oto Melara 76 mm gun. [1]
