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.
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.
