Pr. 677 Lada class submarine built under a deeply improved design has fulfilled all the planned trials and has been commissioned today by the Russian Navy. The ceremony of raising the Russian naval ensign on Kronstadt submarine took place at the Admiralty shipyards. Rubin Design Bureau is the designer of the submarine.

The keel-laying ceremony of Kronstadt took place in 2005, but Admiralty shipyards started the submarine building process only in 2013, after the deep upgrade of Rubin's design had been approved, and the Ministry of Defence restarted building of Lada class submarines. The design solutions grant the new level of combat capacities for a conventional submarine in Russian shipbuilding practice.

The decision of Russian Ministry of Defence to proceed building the batch of Lada class submarines ensured the evolution of the Russian underwater shipbuilding. The third vessel in the series, Velikiye Luki, was launched December 2022. The forth and the firth Lada class submarines are under construction at the Admiralty shipyards with their keels laid June 2022. Thereby, the Russian Navy will be expanded by submarines, which have the upper hand in a duel situation.

Lada class is featured by ultra-low acoustic signature, significantly lower than that of previous diesel-electric submarines. That is facilitated by ship mechanisms with low vibration activity, made specifically for these submarines by Russian companies. The vessel is armed with powerful missile and torpedo weaponry with an option to strike sea and land targets.

The tradition of naming a ship in honor of the northern outpost of Russia comes from the 18th century. The first Kronstadt, a sailing battleship, participated in the Russian - Swedish war of 1741-1743, when Russia won and kept its new territories in the Baltic Sea region. The second Kronstadt, a large ASW ship, was built in Leningrad at the Northern shipyard and served in 1969-1992, performing reconnaissance and surveillance missions. In 2005 the name Kronstadt was given to the forth generation submarine, the representative of the class, which is to be the backbone of the Russia's conventional submarine forces.
