Be-2500 Neptun
Role Super-heavy amphibious transport
Manufacturer Beriev Aircraft Company
Status In development

The Beriev Be-2500 Neptun (Cyrillic: Бериев Бе-2500 Нептун) is a super-heavy amphibian cargo aircraft concept being developed by the Beriev Aircraft Company of Russia. Its maximum takeoff weight is projected to be 2,500 metric tons, hence the designation.

It is designed to function as both a conventional high-altitude jet and as an Ekranoplan. It is intended to fly transcontinental routes, taking off from conventional seaports and requiring no special infrastructure.

If it enters service, it will become the new largest aircraft in the world, surpassing another aircraft designed in a territory of the former Soviet Union, the Antonov An-225.

Beriev states that if this plane is to become a reality investments from several countries are needed.
