This year, Russia will begin building two diesel-electric submarines under Project 667 (Lada series).

Submarine B-585 St. Petersburg, the leading submarine of the Lada series, entered service with the Northern Fleet already in September 2021. The United Shipbuilding Corporation (USC), a Russian open government shipbuilding company, has announced that it plans to start building two more submarines to Europe’s largest naval fleet by the end of this year.

Beyond the two submarines scheduled for production this year, the Russian Navy is set to receive two diesel submarines this year: the B-586 Kronshtadt and the B-587 Velikiye Luki.

According to defenseworld.net, Project 667, which is developing the fourth generation of Russia’s diesel-electric submarines, has now been recognized as the world’s most advanced nonnuclear submarine development project in terms of combat effectiveness and other tactical and technical parameters.
