The two vessels were monitored about 14.5 nautical miles off of Latvia’s Exclusive Economic Zone (EEZ) maritime jurisdiction. According to NBS reports, a civilian tug-boat was towing an unidentified Serna-class air-cavity landing craft.
Air-cavity ships are designed for rapid deployment of troops onto coastal shores and quick maneuvering either for a quick retreat or for repeat retrieval and delivery of more personnel and armored technical equipment up to a 92-person crew and 45 tons of gear.
The high-performance ship can cover a 600-mile distance at speeds up to 30 knots. Its approximate load capacity allows for expedited transport of a battle tank and two armored personnel carriers on its landing deck.
