Orlyonok Ekranoplan

The A-90 Orlyonok is a Soviet ekranoplan that was designed by Rostislav Evgenievich Alexeyev of the Central Hydrofoil Design Bureau.

The A-90 uses ground effect to fly a few meters above the surface. The Russians classify it as Ekranoplan Class B – it can achieve an altitude of 3,000 m, placing it between Class A – which is limited to ground effect, and Class C, which exploits the ground effect only during take-offs and landings and otherwise functions as a typical airplane.
