La clase Vishnya (Project 864), también conocida como clase Meridian, es una clase de buques de recopilación de inteligencia de señales de diseño soviético construida en Polonia para la Armada soviética y posteriormente rusa. Los buques son plataformas SIGINT y COMINT construidas específicamente, con antenas de enlace satelital, sonar y armas de autodefensa de corto alcance; su empleo documentado en tiempo de guerra incluye despliegues rusos en torno a Siria y la misión de seguridad de gasoductos del Priazovye en el mar Negro en 2023 durante la guerra Rusia-Ucrania.

Class Members And Fleet Context

Project 864 fue una pequeña familia de siete buques soviéticos de recopilación de inteligencia construidos en Gdansk para tareas de vigilancia radioeléctrica, electrónica, sonar y regional a nivel de flota. Las fuentes abiertas describen repetidamente la clase tanto por el nombre OTAN Vishnya como por el nombre soviético de proyecto Meridian.

Armas de autodefensa

La clase está construida en torno a la recopilación de inteligencia más que al ataque ofensivo, pero KCHF lista una configuración limitada de defensa puntual.

Open-source class metadata places it between the earlier Primor'ye surveillance ships and the later Vishnya intelligence ship family, with four hulls completed from 1980 to 1987 and a defensive fit that included Strela-2 launchers and AK-630 close-in weapons.

Ivan Khurs brought the class into the Black Sea Fleet and has been documented in the Russia-Ukraine War through Ukrainian attacks on Russian naval assets at sea and in occupied Sevastopol.

The class combines a monolithic fiberglass vacuum-infusion hull with trawls and unmanned mine-hunting vehicles, and it entered the Russia-Ukraine war record when Ukrainian intelligence said it disabled the Baltic Fleet lead ship Aleksandr Obukhov at Baltiysk in October 2024.

The design combines a fiberglass hull, mine-search sonar, sweep and mine-destruction gear, a 30 mm AK-306 gun, and an Igla-1 self-defense missile fit; RT-233's 2023-2024 fleet movement gives the class a sourced but limited 2014 Russia-Ukraine War connection rather than confirmed combat-loss evidence.
