A ceremony of launching the newest submarine Velikiye Luki of project 677 Lada was held in St. Petersburg
Submarines of this project belong to the fourth generation of non-nuclear submarines. To date, they are recognized as the most modern and promising domestic non-nuclear submarines, both in terms of combat effectiveness and other tactical and technical characteristics. The only shipbuilding plant of this class is JSC “Admiralty Shipyards.”
The hull of the submarine is made of AB-2 steel. The submarine has a length of 72 m and a width of 7.1. She can reach a maximum speed of 21 knots (39 km/h) underwater and 10 knots (19 km/h) on the surface.
Russia continues to replace Soviet-era Project 877 diesel-electric submarines with more modern Project 636.6 and 677 submarines.
