Beriev Be-2500

The Beriev Be-2500 Neptun (Бериев Бе-2500 Нептун) is a super heavy amphibious transport aircraft that, as of 2007, was in design and development by Russian design firm Beriev. The maximum takeoff weight is estimated at 2500 tons, hence its name.[1][2]

Design and development

It has been designed to serve both as a conventional jet aircraft, flying at high altitudes transcontinentally, as well as a craft using the ground-effect at intercontinental routes across the sea. It is planned though to preferably fly through intercontinental routes, taking off from normal sea ports without needing special infrastructure. The concept derives from the VVA-14 of the 1970s.

If it entered service, it would become the new largest airplane in the world.[3]

The concept of the aircraft was developed in 1980s by the Beriev Design Office in collaboration with TsAGI and TsIAM. There are two versions of the design that differ in the arrangement of the gear units and in the geometric design of the dragon structure. Initially, the NK-116 engine was designed to be installed, but foreign engines were also introduced, including the Rolls-Royce Trent 800 and General Electric GE. The NK-116 plans were developed by samara i [Kuznyecov Design Office] by 1994. Beriev is planned to cooperate with foreign partners in the development of the aircraft, including financing issues. It was estimated in 2007 that the cost of a development program would reach $ 10–15 billion.[1]

The company claims that such aircraft would operate as a "flying ship" that would compete with the shipping and air transport industries and could easily be integrated into the existing infrastructure.
