The Beriev A-40 Albatross, designed for anti-submarine warfare, was intended to replace older aircraft. Efforts have been made to revive it, including the A-42 program with upgrades and radar. However, the future of the A-42 remains uncertain due to engine production issues, sanctions, and shifting military priorities.
The collapse of the Soviet Union in 1991 led to the cancellation of many Soviet aviation projects, including the Beriev A-40/A-42 Albatross. When shelved, one prototype was completed, and a second was 70% or 80% complete. The Soviets were leaders in water-based aircraft such as the Lun-class ekranoplans and the proposed Beriev Be-2500 ekranoplan.
The Beriev A-40 Albatross is a large jet-powered amphibious flying boat that received the NATO reporting name Mermaid. It was designed by Beriev Aircraft Company, which also built the world's only in-service jet-powered amphibious aircraft, the Beriev Be-200. The A-40 first flew in 1986 and was publicly revealed at the Tushino Airshow in 1989.
