The first full-size model of Russia's future long-range bomber PAK DA, being developed for the Aerospace Force, has been created by the Tupolev company, a source in Russia's defense-industrial complex told TASS.

"Several scale mock-ups of the PAK DA bomber have been made of composite materials. Also, there is a full-size mock-up made of wood. All models are based on the flying wing concept," the source said.

The airframe will be made of radar-absorbent material. All weapons will be placed inside the fuselage.

"Also, PAK DA is to be equipped with the latest radioelectronic warfare equipment of domestic manufacture, unparalleled in terms of effectiveness," the source said.

Another source in the Russian defense industry said the first test sample of a future bomber will perform its first flight by 2025. The plane will have a subsonic speed.
