The Russian Navy officially accepted the new large diesel-electric submarine “Yakutsk,” of Project 636.3, into its fleet on June 11 in St. Petersburg. The ceremony took place at the Admiralty Shipyards, a subsidiary of the USC enterprise.

Deputy Commander-in-Chief of the Navy, Admiral Vladimir Vorobyov, oversaw the solemn event and expressed his wishes to the submarine crew to perform their duties with honor under the St. Andrew’s flag.

The “Yakutsk” is the sixth submarine in the series intended for the Pacific Fleet. It was laid down in August 2021 and launched in October 2024.

Submarines of Project 636.3 are known as “black holes” within the fleet due to their exceptional quietness.

These submarines have a displacement of over 3.9 thousand tons and a length of 74 meters.

They can reach speeds of up to 20 knots and have an endurance of up to 45 days at sea.

Each submarine is equipped with 6 533-mm torpedo tubes and can deploy torpedoes, mines, and Kalibr-PL cruise missiles.

The submarines of this class are designed to perform a wide array of missions, including patrolling, reconnaissance, and the destruction of both surface and underwater targets.
