A modern littoral role for the ekranoplan

Would bringing a Russian ekranoplan back into service make sense?

Possibly in confined theaters such as the Black or Caspian seas, where high speed and concentrated firepower could suit a specialized littoral role.

A plausible niche exists in confined waters such as the Black Sea and Caspian Sea. There, a fast ground-effect craft carrying substantial weapons could create a sudden regional threat without needing blue-water endurance. The answer treats the ekranoplan as a specialized littoral system rather than a general substitute for ships or aircraft.
