The OTO 76/62 Super Rapid is Leonardo's Italian 76 mm naval gun mount for corvettes, frigates, patrol vessels, and other surface combatants. It combines a selectable 120-round-per-minute rate of fire, an 80-round ready magazine, anti-surface and air-defense roles, optional Strales/DART guided-ammunition integration, and compact installation on small naval units. Its 2014 Russia-Ukraine War link is Ukraine's Ada-class corvette program: Naval News identified a Leonardo 76 mm Super Rapid fitted to Hetman Ivan Mazepa during sea trials in Turkiye while the corvette project remained shaped by wartime transfer constraints.
Naval News reported that Ukraine's Ada-class corvette Hetman Ivan Mazepa was fitted with a Leonardo 76 mm Super Rapid gun during Turkish sea trials; the source also notes the corvette's transfer and completion plans were affected by Russia's invasion.
Role detailsThe Super Rapid mount is not just a faster 76 mm gun. Leonardo's current material emphasizes integration with ship combat-management systems, a digital control console, rapid tactical response, optional multi-feeding, muzzle-velocity radar, a stealth shield, and Strales/DART guided-ammunition support.
Leonardo lists a maximum range of 16 km with standard ammunition and 20 km with extended-range SAPOMER ammunition.

The 76/62 family spans the earlier Compact mount, the higher-rate Super Rapid mount, Strales/DART guided-ammunition configurations, and later above-deck Sovraponte / OTO AD installations.
