The Alekseyev A-90 Orlyonok ekranoplan, first flying in 1972, represents Soviet ground-effect craft technology development and innovative aeronautical engineering philosophy. This six-crew vehicle spans 31.5 meters, reaches 400 km/h, and achieves a 1,500-kilometer range through unique wing-in-ground-effect flight principles. It exemplifies experimental propulsion concepts and specialized operational requirements developed by the innovative Alekseyev bureau.
