In Russia, the development of ekranoplans has begun again. Petrozavodsk began testing the experimental ekranoplan "Orion-25", built at the local shipbuilding enterprise "Avangard". The exoplanet is unique because it can reach high speed like an airplane, and at the same time it is adapted for autonomous navigation, like a ship. The Orion-25 eco plan can be used for border protection, military and scientific purposes, and for disaster relief. It should be noted that "Orion-25" is not the first ekranoplan, the tests of which began in Petrozavodsk. In 2012, Orion-20 was developed, but after a serious accident, its development was suspended. The Orion-25 ekranoplan is capable of flying at low altitude from the surface of the earth, water, snow or ice. It develops a speed of up to 500 km / h, its flight range is up to 3600 km, and its duration is up to 11 hours. The fuel consumption of an ekranoplan is small due to the ship's screen effect.
