Russian Navy’s second Lada-class submarine Kronstadt enters service

Russian Navy has commissioned the second Project 677 Lada-class submarine Kronstadt (B-586).

As disclosed, the vessel formally entered service at a ceremony at Admiralty Shipyards in St Petersburg on January 31.

Specialists from the Admiralty Shipyards built Kronstadt according to an adjusted design. The ship’s technical control system, electric propulsion system, and navigation complex have been modernized.

The submarine started sea trials back in December 2021. The keel was laid in July 2005 and the launching ceremony was held in September 2018, 13 years after the construction started.

“We are accepting a new generation non-nuclear submarine into the fleet. During state tests, the ship demonstrated all the best qualities that the designers had put into it and confirmed its combat characteristics. The project was brought to life by the golden hands of the shipbuilders of the Admiralty Shipyards. This is the first submarine to join the Northern Fleet brigade. In the Northern Fleet, she will practice all her combat qualities,” Commander-in-Chief of the Russian Navy, Admiral Nikolai Evmenov stated.

Project 677 submarines are the fourth generation of the Russian Navy’s diesel-electric submarines, measuring 66.8 meters in length. They can dive to a maximum stated depth of 300 meters and can operate non-stop for 45 days with a crew of 35. They displace 1,765 tons while surfaced and have six torpedo tubes.

The keel for the lead sub in the class, Sankt-Petersburg (B-585), was laid down in December 1997 and launched in October 2004. The submarine was delivered to the Russian Navy in April 2010 and commissioned in May 2010.

The Russian Navy plans to buy a total of eight Lada-class submarines.
