Air-cavity Fast Landing Craft D-144
Project 11770 / Serna Class

The Project 11770 air-cavity fast landing craft in wartime is designed for over-the-beach landing of combat and military tracked and wheeled vehicles, as well as forward assault units. In peacetime, the boat can be used to deliver equipment, cargo and troops to the points of the seacoast to a distance of 600 miles.

The Project 11770 Serna landing boat has improved design and seaworthiness through the use of corrosion-resistant alloys, extruded sections and panels, and a powerful power plant. The boat is equipped with an integrated movement and facilities management system. The feature of the Serna landing craft is that an air cavity, an artificial air gap with overpressure, is created under its bottom as it moves. The cavity isolates a large portion of the hull from contact with water, thus achieving a significant reduction in resistance and providing a speed of 30 knots, as well as reduced fuel consumption.

It can transport cargo and equipment up to 45 tons at 30 knots in sea point up to 2 (at 27 knots in sea point up to 3). The sea-going capacity is limited by sea point 5.

Air-cavity Fast Landing Craft D-144 laid down at the Volga Shipyard, Nizhniy Novgorod (yard No.805), commissioned 19.02.2008.

Now in service.
