The Italian Otobreda 76/62mm Compact a dual-purpose anti-surface and anti-aircraft naval cannon with a low weight and a high rate of fire. Since its introduction in the late 1960s the OTO-Melara Compact[1] has dominated the 57mm to 76mm medium caliber naval cannon market and has been fitted to hydrofoil missile boats as small 62 tons to large guided missile destroyers of 3500 to 4500 tons.[2]
History
editThe Compact was a development of the earlier 1950s OTO-Melara [3]Allargato dual-purpose naval cannon of the same caliber.[4]
Description
editThe 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.[5]
