The 1124P project corvette (NATO reporting name: Grisha I class, Soviet classification: MPK-147 class Russian: МПК-147) were intended to counter enemy submarines in nearby area of naval bases, ports and scattered berths, on the deployment of naval forces to carry out anti-submarine surveillance and protection of ships and vessels at sea.

Control of firing AK-725 was carried out by the MR-103 Leopard radar with a maximum detection range of 40 km, which was also located on the stern superstructure.

On 13 March 1987, as a result of a three-day search of the CPUG (MPK-52, MPK-127 and MPK-93), the MPK-52 discovered an underwater target at a distance of 13 km (8.1 mi).

As a result of almost a day of persecution, the Turkish submarine was forced to enter the territorial waters of Turkey and ascend.
