The Otobreda 76 mm gun is a naval artillery piece built by the Italian defence conglomerate of Otobreda, developed originally from the Oto Melara 76/62mm Allargato, which was bigger, heavier and had a slower rate of fire. A vehicle-mounted version known as the Otomatic was built for the self-propelled anti-aircraft gun role, although this was not put into production.
The gun 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 and directed fragmentation. 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 (a vessel somewhere between a corvette and a patrol boat), or patrol boats. It has been widely exported and is in use with 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]
