Landing craft project 21820 Dugong was developed in Nizhny Novgorod, somewhat similar to the “Chamois“, but having larger dimensions and, as a result, large amphibious capabilities. Thus, with a an overall length of 45 meters and width of about 8 meters, “Dugong“ can carry up to 140 tons of load. It can be two tanks, five armored personnel carriers or infantry fighting vehicles or up to 150 troops. It is noteworthy that the carrying capacity of the Dugongs allows it to take on board three T-72, T-80 and T-90, but the size of the deck does not allow taking full advantage of this opportunity. In the case of heavy armor, the 21820 boat can carry no more than two tanks. The rest of the load may be used for infantry or other goods. Otherwise, the performance Project 21820 boats is roughly the same as that of the «Chamois». A distinctive feature of the ship is an artificial air cavity on the bottom to achieve high speed and efficiency in the movement. The first ships dynamically supported were based on static air cushions with powerful fans and a huge fuel consumption. The air cavity vessels are more economical than the hovercraft. In both types of the special contours of the bottom is a layer for holding compressed air. This method of maintaining a dynamic principle (DPP) does not require complex design solutions and high energy costs. Preceded by high-speed landing craft project 11770 Serna, Dugong, still has no analogues in the world. “Dugong“ far superior “Serna“. It has low visibility, large displacement allowed at times to increase capacity and Troops capacity, speed, range, seaworthiness, with with efficient weapons fire support of landing. Десантные катера проекта 21820, проектный шифр «Дюго́нь», тип Д-105 — серия быстроходных десантных катеров на воздушной каверне для ВМФ ВС России. По кодификации НАТО «Dyugon»/«Ataman Platov». Катера проекта предназначены для скоростной переброски морем и высадки на необорудованное побережье людских контингентов, колёсной и гусеничной техники. Проект десантных катеров 21820 был разработан в «ЦКБ по СПК им. Р. Е. Алексеева». Предшественник данного проекта, до сих пор не имеющий мировых аналогов — скоростной десантный катер проекта 11770 «Серна», также разработан в ЦКБ по судам на подводных крыльях им. Р. Е. Алексеева. Размеры грузового трюма — 27 × 6,8 × 2,34 метра. Десантные возможности: 2 основных боевых танка, или 4 БМП/БТР, или 140 т груза, или 90 чел. десанта.
