Proship Design Bureau is based in the very center of Russian nuclear shipbuilding. It was here, in Severodvinsk, that the foundations of the engineering industry were laid at one time, design yards, plants and enterprises were among the first in the country. The experience and knowledge handed down from generation to generation still play a key role today – many specialists are trained and educated in the field of shipbuilding here, and the continuously improving technologies and design methods are a priority for the industry to this day.

First shipyard projects
In October 1940 an order was given to suspend the construction of the battleship “Soviet Belorussia” ready for 1% and to concentrate main efforts on the battleship “Soviet Union”.

At the end of the war the unfinished battleships were dismantled.

Zvezdochka Machine-Building plant
In 1970, Zvezdochka completed the repair and modernization of the world’s first nuclear-powered icebreaker Lenin. During the repair of “Lenin” unique work on replacing the nuclear propulsion system of the ship was carried out. In 1970 for successful fulfillment of the state plan the plant was awarded the highest award of the Soviet Union – the Order of Lenin. In the beginning of the 1970s, the company expanded its ship repair competence. Two Project 667A strategic missile carriers were accepted for repairs.
