Russian shipbuilder Sevmash officially started construction the country’s seven and final Yasen-class submarine Ulyanovsk in a ceremony on Friday, July 28.
The boat is also the sixth modernized unit in the class.
The nuclear-powered Yasen-M submarines are considered by many to be the pinnacle of Russian submarine technology.
Also known as Project 885, the attack submarines are being built by the Sevmash shipyard in Severodvinsk, Russia, under a design by St. Petersburg-based Malakhit Central Design Bureau.
The first submarine in the class, Severodvinsk, was delivered to the Russian Navy in 2013, twenty years after it was laid down in 1993. Following sea trials, the submarine was commissioned in 2014.
The first Yasen-M boat was laid down in July 2009.
With a submerged displacement of 13,800 tons, Project 885M submarines are armed with 24 Oniks (SS-N-26) and Kalibr (SS-N-27) cruise missiles in addition to torpedoes. They are reportedly one of the quietest submarines to be operated by Russia.
