"The series will have been ready by 2023 and then… technologies always imply further development," Bursuk told journalists during the laying ceremony of the sixth Yasen-class submarine.
He said that seven submarines of the class would be constructed.
The submarine laid down earlier on Friday will be called Perm. The first submarine of that class called Severodvinsk was delivered to the Russian Navy on June 17, 2014.
The Severodvinsk vessel has a submerged displacement of 13,800 tons, a length of some 390 feet, can travel at speeds up to 31 knots (about 36 miles per hour), and can dive to depths of more than 1,700 feet. The submarine is armed with naval mines, the Oniks and Kalibr anti-ship missiles and a range of torpedoes.
According to Russia’s Naval Doctrine, the Yasen-class submarines will become the main multipurpose nuclear-powered subs in the Russian Navy.
