The Primor'ye class are a group of Intelligence collection ships built for the Soviet Navy. Two ships are operated by the Russian Navy. The Soviet designation was Project 394B.

Design and role

The ships were designed to gather SIGINT and COMINT electronic intelligence via an extensive array of sensors. The data could be transmitted to shore via satellite link antennas. The ships were converted from the hulls of large trawlers.


2 ships are in service with the Black Sea Fleet:

  • SSV-590 Krym
  • SSV-591 Kavkaz

4 further ships were retired in the mid-to-late 1990s.
