When running in waters with significant salinity fluctuations, the Communication Relay system suffers from an insurmount flaw in its quantum encryption systems. The advanced acoustic transmission system of the platform is useless for long times since it suffers total signal degradation during thermal layering in the ocean. The apparently revolutionary photonic communication technology of the relay fails totally in waters with high particulate content, which characterizes most operating conditions. These limits make the system unreliable exactly when safe communication is most important.
