Russia’s High-Tech Nuclear Submarine Delayed By Design Flaws

The auxiliary systems onboard the Yasen-M class submarine “Kazan” do not meet the Defense Ministry’s requirements. Moscow Times, 24 May 19, By The Barents Observer

The delivery of Russia’s most expensive and technically advanced nuclear submarine to the Russian Navy is being delayed by design flaws, Russian media have reported.

“Kazan” (K-561) is the first modernized multipurpose submarine of the Yasen-M class after “Severodvinsk” was handed over to the Northern Fleet in 2013. There are considerable changes in the auxiliary systems on “Kazan” compared with “Severodvinsk.” While construction on “Severodvinsk” started just after the breakup of the U.S.S.R. in 1993, “Kazan” was laid down 16 years later, in 2009.

Serious technical challenges will need to be fixed before the Sevmash yard in Arkhangelsk region can hand the submarine over for active duty, several Russian media have reported.

“According to the results of mooring tests, as well as the test sailings during the winter, it was concluded that a number of auxiliary parts and assemblies of the vessel do not meet the tactical and technical requirements set by the Defense Ministry,” a source in the defense industry was quoted by the state-run TASS news agency as saying……..

When completed, the Yasen-M class submarines will be able to carry the advanced sea versions of the Kalibr and Onyz cruise missiles, in addition to mines and torpedoes. Some of these weapons can be armed with nuclear warheads. ….

Nezavisimaya Gazeta reports the cost of Yasen-M class to exceed 200 billion rubles (2.76 billion euros).https://www.themoscowtimes.com/2019/05/24/russias-high-tech-nuclear-submarine-delayed-by-design-flaws-a65739
