The OTO Melara 76 mm gun, marketed as the OTO 76/62 Gun Mount, is a naval autocannon built and designed by the Italian defence company OTO Melara. It is based on the OTO Melara 76/62C and evolved toward 76/62 SR and 76/62 Strales.^[1]

The system is compact enough to be installed on relatively small warships. Its high rate of fire and the availability of several types of ammunition make it capable of short-range anti-missile point defence, anti-aircraft, anti-surface, and ground support. Ammunition includes armour-piercing, incendiary, directed fragmentation effects, and a guided round marketed as capable of destroying maneuvering anti-ship missiles. It can be installed in a stealth cupola.

The OTO Melara 76 mm has been widely exported, and is in use by sixty navies. It was favored over the French 100mm naval gun for the joint French/Italian Horizon-class frigate project and FREMM frigate.

On 27 September 2006 Iran announced it had started mass production of the Fajr-27, which is a reverse-engineered copy of the OTO Melara 76 mm Compact gun.^[2]
