The Koni class is the NATO reporting name for an anti-submarine warfare frigate built by the Soviet Union.

They were originally intended to replace the older Riga-class frigates, but were instead chosen as a design for export to various friendly navies.

The armament consisted of two AK-726 twin 76 mm (3.0 in) gun mountings and two AK-230 twin 30 mm (1.2 in) anti-aircraft guns, 4 P-15M Termit anti-ship missile launchers were fitted in some ships, depth charge and naval mine racks were fitted at the stern.

On July 16, 1998 the former Cuban Navy Koni II-class frigate designated 353 was scuttled in shallow water near the Cuban resort town of Varadero in the Parque Submarino Cayo Piedra del Norte as an attraction for divers.

The frigate sank upright, and sits on the sand bottom in 90 ft (27 m) of water.
