A-90 Orlyonok

The Soviet Navy command of the 1960s was very interested in a fast military transport capable of carrying a large payload.

The Central Hydrofoil Design Bureau was one of the organizations working on this top-secret project, about which little was known until the fall of the Soviet Union.

Unlike other Soviet Ekranoplan designs, the Orlyonok was amphibious and was equipped with wheels for beaching and land based takeoffs.

Under cruise conditions and in ground effect, the front engines could be shut off since their power was unnecessary to keep the aircraft aloft; this also minimized intake of water, salt and low flying birds.

The front end of the Orlyonok was hinged behind the radome and the whole assembly could open sideways to speed disembarkation of the infantry it carried, or of a BTR armoured personnel carrier.
