MOSCOW, March 21. /TASS/. The order books of Russia’s naval shipyards are full till the end of 2023, with the defense order accounting for about 80% of incomes of the United Shipbuilding Corporation, the company’s president, Aleksey Rakhmanov, told the media.

"As for naval shipbuilding is concerned, our order books are full till 2021-2023. Most of our shipyards were not so busy even in the Soviet years," he said.

About the overall share of the state defense orders in the USC’s overall revenue Rakhmanov said that it had not changed greatly over the past five years, remaining at the level of about 80%.

"At the moment the work load on shipyards varies greatly in terms of the number of projects and the time required for coping with them. We are coming close to the unification of that process to keep each shipyard and each building berth busy," he said.
