The Beriev Be-2500 Neptun transoceanic-amphibious aircraft will be capable to take away four times bigger payload than Antonov An-225. At the moment the An-225 is the largest aircraft of the world.
In order to be familiar with the size of these planes, lets see the smaller first. We made a video at the last visit of the Antonov An-255 in Budapest.
The planning of the Be-2500 started as a military contemplation, but continued as a civilian project. This is the usual way of Beriev’s practice. The story of the Beriev Be-200 firefighter- and airliner-family is a good example.
From the view of solutions, the “Monster of the Caspian sea” (or ekranoplan) could be an antecedent of the Neptun’s design. Some of the engines of the Be-2500 were also placed at the nose of the aircraft.
Some facts about the aicraft expected to arrive at 2022: the wingspan is almost as long as the lenght of the aircraft (130 meters). With its pressurized cabine, the Be-2500 is able to fly with a speed of 800 km/h at altitude around 10 000 meters. This power is provided by six engines.
Be-2500 is able to fly at 400 meters, exploiting the cushion effect (“wing in ground”). This time the speed is only a little bit more than 400 km/h.
This giant is capable to take away a payload of 1000 tons for more than 16 000 kilometers. More accurate details available on the Beriev-link below.

Due to the expansion costs (10-15 billion dollars) it is not sure we will ever see the Neptun flying. Notwithstanding, if the Be-2500 project would come to fruition, we hope to see an airliner version as well.
Compared to the australian low-cost Airbus A380 (with more than 800 seats available), the Neptun would be capable to provide almost twice as many seats onboard.
After a hundred years, a flying boat will be the largest airliner again?
