The K-571 Krasnoyarsk, fourth submarine Project 885M class Yasen, has completed the hull seal tests. This is what is communicated by the Sevmash Shipbuilding Company, in Severodvinsk, northern Russia.
"The submarine has successfully passed the deep seal tests, according to the operating specifications provided by the designer. Once this phase is completed, sound insulation and the installation of internal structures will be carried out".
The fourth generation multirole nuclear attack submarine class Yasen (designation NATO Graney), has a displacement in immersion of 13.800 tons. It has a length of 119 meters, with a maximum speed of thirty one knots in immersion. Can dive up to 600 meters, with 500 operating depth. It has a crew of ninety men, including thirty-two officers.
The specifications of the 885 Project foresee a double non-magnetic steel hull so as to reduce the acoustic trace and a greater survival capacity of the boat compared to the Akula I / II. The single shaft is powered by a OK-650V fourth-generation thermo-nuclear reactor from 200 MW pressurized water cooled made by Afrikantov OKBM. The command tower has an oval hydrodynamic shape, while the hull is divided into ten compartments.
the class Yasen is designed to launch cruise missiles with conventional or nuclear warheads, engage submarines and surface units and target coastal targets. In primary form, each submarine Yasen carries 24 / 32 cruise missiles on eight vertical launch tubes. Eight 650 mm and two 533 mm torpedo tubes.
The K-560 Severodvinsk, the first Russian attack submarine project 885 class Yasen, 17 June 2014 was delivered. His long operational evaluation ended in the spring of 2016, however he was handed over to the Navy with many doubts. The Naval Staff would not have been fully convinced of the Severodvinsk for unspecified technical problems. A government commission set up for the occasion authorized the entry into service with some improvements adopted in the following ones Yasen. The K-560 subsequently successfully completed four sea trials. The improvements proposed by the Russian Navy commission have been implemented in the K-561 Win, K-573 Novosibirsk, K-571 Krasnoyarsk and the K-564 Arhangel'sk, respectively second, third, fourth and fifth submarine of the class. The class is part of the 885M Project Yasen-M updated. The construction site of the sixth class submarine Yasen, Perm (photo), was officially opened last July. Sevmash Shipbuilding Company, will start production of the seventh and last unit of the fleet next June.
the class Yasen Project 885 / 885M, will be operational by 2023 and will replace class submarines Oscar ed Akula. The second class submarine Yasen will enter service by the end of the year. Every class submarine Yasen has an average cost of 1,5 billion dollars, the equivalent of a Los Angeles and a third of the class Seawolf. The average cost of the class Virginia is 2,7 billion dollars.
