After being subject to change for sixteen years at the shipyard in Severodvinsk, the nuclear-powered submarine BS-64 Podmoskovye, he has taken to the sea for an operation classified.

The K-64, the third strategic Delta-IV class submarine, was moved in 1999 from its base on the Kola Peninsula to the Zvezdochka shipyard in Severodvinsk. The unit has been converted to house the experimental Russian mini-submarines operating deep in the icy Arctic waters. The middle section, designed to accommodate sixteen ballistic missiles, has been modified to the new asset. The BS-64 Podmoskovye is considered as the first Russian submarine carrier for the drones and divers for the 10830 project Losharik. The hull was lengthened to 162.5 meters, the defensive capabilities were not dismantled. A few hours ago, the Rossiskaya Gazeta has confirmed the departure of Podmoskovye for the White Sea.

The 10830 project Losharik

The Losharik nuclear-powered submarine, is designed for special operations, scientific research and rescue at great depths. The Losharik is one of the secrets of the country projects: in fact, those who have worked in the shipyard of Sevmash N42, were kept under tight military control for the fifteen years necessary for its development.

The Losharik, hero of a famous Soviet animated film, nothing is known except that it is able to reach the six thousand meters deep and it is powered by a nuclear reactor of new conception. It should be about 60 meters long with a crew that should not exceed 25 units. 10830 The project exploits the principles of the bathysphere, a form needed to withstand enormous water pressure at that depth. The outer casing is the real shield against the pressure. Inner hull, instead, is separated from batisfera from a highly compressed material. The Losharik could sail unmolested in any part of the globe with impunity. The disadvantages are related to the limited space for the crew and to the low cruising speed. And 'certainly the first nuclear-powered boat capable of reaching such depths: the American NR1 could reach three thousand meters. His only known mission was carried out with the Northern Fleet to a depth of three thousand meters, the Mendeleyev ridge in the Arctic.

The Delta IV class

The Delta IV class, 667BDRM Project, Delfin, is in service with six units (the seventh is the BS-64 Podmoskovye that pitchers have been removed). The Delfin, to date, are the backbone of Russia's nuclear deterrent. The entire class has been converted to be equipped with the latest version of the R-29RMU Sineva missiles, the Layner U2, operational by the end of 2014. Unlike the Bulava, of the R-29RMU2 Lajner fire tests performed by K -84 Ekaterinburg and the K-114 Tula, have proved immediately successful. With the new weapon system, capable of carrying up to twelve warheads MIRV / Marv variable return, the service life of Delfin was extended until 2030, when it will begin the gradual removal from service.
