This category collects articles about hydrofoils and ekranoplans built in Gorky and Nizhny Novgorod. All of these projects originated from the Central Design Bureau for Hydrofoil Ships named after R. E. Alexeyev, the design bureau that engineered the first mass-produced passenger hydrofoils and the Soviet Navy's combat ekranoplans. Among its key designs were the Raketa (hydrofoil))))" and Meteor (hydrofoil))))", which became mass river transport across the USSR, as well as the experimental KM (ekranoplan), the heaviest aircraft of its time. The tradition continues: modern vessels such as the "Meteor 120R"""")" and the "Valday 45R" are built at the design bureau's production site in Nizhny Novgorod Region.
