The system is intended for submarine/coastal command post communication, as well as communication with any type of interacting and support forces.

The system provides:
     in underwater position:

radio reception in VLF, LF, MF and HF wave bands on a trailing towed array;
     in periscope and surface position:

duplex voice communication and continuous wave telegraphy in HF and VHF wave bands;

radio reception in VLF, LF, MF, HF and VHF wave bands on extendable antennas and in VLF on a crossed-loop antenna;

satellite communication in INMARSAT-C system;

reception of satellite navigation system signals;

reception of signals from Shore Radio Navigation Systems (Omega, Loran-C);

control of the system's communication facilities, monitoring of their state, reception and transmission of messages, their documenting and archiving from a unified workstation.

It is possible to replace a cable antenna, trailed out of the submarine pressure hull, in submerged position.

Minimum power consumption in underwater position.
Backup control of communication facilities.
