Beriev Be-2500

From Wikipedia, the free encyclopedia

This article contains information about a scheduled or anticipated future aircraft. It may contain preliminary or speculative information, and may not reflect the final version of the aircraft.

The Beriev Be-2500 Neptun (Cyrillic: Бериев Бе-2500 Нептун) is a super-heavy amphibian cargo aircraft concept being developed^{[citation needed]} 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 sea-ports 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.
