On April 23, the submarine K-139 of the Oscar II class was in the Sevmash shipyard in the Nikolskoye estuary at Severodvinsk, Russia, christened "Belgorod". "Belgorod" is with 184 m the longest submarine in the world, the displacement is 30,000 tons (submerged), which she nuclear submarines (SSBN / SSGN) of Russian Typhoon and the Ohio class of the US Marine exceeds. 1992 already laid down on, so took his completed a total of 27 years. In 2000, after the disaster with the previous boat K-141 "Kursk", the construction for more than a decade has been lost.

K-139 belongs to the project 949A or "Antey", the 3rd generation of Russian nuclear submarines. eight of those built from 1982 to 1996 eleven ships are in use, two were scrapped, K-141 "Kursk" sank in August 2000 in the Barents Sea. As the twelfth ship of this designed for the use of cruise missiles submarine type (SSGN) K-139 was revived for a new purpose with modified design, continued in December 2012 as a project 09852 and a "special research and rescue U- boot "or multifunction submarine converted.

The hull has a dock for small and unmanned submersibles (eg UUV (Unmanned Underwater Vehicles) and submarine rescue vehicles) expanded. Thus, the former attack submarine is now for the nuclear-powered mother ship for up to eight underwater drones. You should expose underwater equipment and carry out cable laying or inspections. , It may take or smaller (autonomous) underwater vehicles piggyback record even in itself. At the ship's hold, the autonomous underwater vehicle HARPSICHORD 2P-PM can dock. There is also a station for carrying submarines up to 70 m length (relevant circles mention the projects 18511 and 10831 (LOSHARIK), applicable both up to 1000 m depth, equipped with multiple robot arms nuclear-powered deep sea diving equipment, which in appearance to Russian Kilo-class remember).

According to the latest one of the main tasks will be the transport and use of POSEIDON. This new weapon was announced by Vladimir Putin in his State of the Nation already on 1 March 2018th At that time he was still called on to participate in the naming.

With an "intercontinental" range of nearly 10,000 km at a maximum speed of 100 km / h (54 knots) is POSEIDON how the weapon is now called, will be able to bring its charge over very long distance to the finish. Based on probably intentionally leaked technical drawings and the evaluation of some published by the Russian Ministry of Defense test images POSEIDON measures about 24 meters in length and 1.6 m in diameter. The sketches show a warhead of about 4 m length and a diameter of 1.5 m, the information on the explosive range from 2 up to 100 Mega tons. The "Belgorod" will have six such POSEIDON. To what extent a re-loading possible (which (a) further charging (s) would require), is currently unknown.

Besides the use of POSEIDON education is a key part of the tasks. The circulating sketches show the device for a towed sonar (towed sonar array). In addition, will probably be used HARMONY, a sensor network for submarine detection that the Russian military will deploy in the Arctic - similar to the SOSUS sonar network of the US Navy.

"Belgorod" can deploy sensors under ice and use his or UUV the carried device to place sensors, which are driven by underwater nuclear generators. Pictures also show a kind of towing equipment, presumably to lay submarine cables. Also make can be seen, which make the use of Jetpropellern suspect that can maneuver the boat in tight spaces, or to keep it for precision work to position. The depth should be about 520 meters (1,700 feet).

As with the other reconnaissance ships are leadership and operational use by Glavnoye Upravlenie Glubokovodsk Issledovanii (GUGI), which largely secret operating Department for underwater research within the Marine Operations Staff of Defense occur. Because of its strategic importance is conceivable that the operational command of "Belgorod" directly in the Kremlin, that is with the President.

POSEIDON Russia promises to boost its second-strike capacity. Possible destinations include support groups, and coastal infrastructure. In March 2018 Vladimir Putin, the Russian and the world public about his plans to strengthen the Russian military response capabilities informed response to US deployment plans in Poland and Romania. He left several videos show on novel weapons systems - including by the now mentioned under the name POSEIDON torpedo. A spokesman for the Russian Defense Ministry confirmed in March compared to 2,019 journalists that the tests were successfully completed with POSEIDON. The training of staff of the carrier vehicle is completed (Note: The crew size will amount to 25). According to Russian media, the testing phase is to be completed in 2019, could be so expected to commissioning by the Navy in the late 2020th

„Belgorod“ - Russlands neues U-Boot mit Atomtorpedos

Analysts speculate whether another OSCAR II class vessel will also be rebuilt, or whether the "Belgorod" remains the only boat of its kind. Also still unclear rule concerning the terms and categorization. POSEIDON is managed under the code name KANYON or STATUS 6 - times as a torpedo and even an underwater drone. The situation is similar in the deep-sea UUV. Here both LOSHARIK and Paltus and both options being Paltus is also called HALIBUT be performed. Relevant Western professionals differ in part from those of other regions of the world.

Both the overall project such Super Torpedo a portion remains skepticism. One of the major challenges of the withdrawal from enemy reconnaissance will include in such a large weapon system. Also, the demands on leadership ability, especially in the case of a so-scale torpedoes with nuclear potential of fundamental importance, because you want to cancel the attack or may carry a target change.

His devastating effect when used in coastal areas is worrisome. In addition to the immediate effects Hits secondary effects are possible by tsunamis - here is reminiscent of Fukushima.

Ultimately, such a weapon also opens a new chapter in nuclear weapons control regime.

With the collapse of the Soviet Union the construction of strategic submarines experienced a slump for budgetary reasons. As a result of"Kursk" -Incidentit stagnated development and construction again. The projects 955 (BOREI class) and 885 (Graney-class) running since 2008, nuclear-powered SSBN (BOREI) and SSGN (graney) to, wherein the hull number 1, "Severodvinsk"Had to dismount from the keel laying 1993 to launch in 2010, some time. Their commissioning took place in the summer, 2014.

Russia opens a new chapter in the Marineseekriegführung with such a submarine mothership.Technological advantages no longer speak to the extent as in the past for submarines. Add to this the advances in techniques and methods of submarineFighting. Use of Big Data, bringing together a variety of sensors to pick just one example, in a position which released from submarine reactors radiation to be detected, requiring new approaches. At the same time it is more expensive to make submarines quieter or to camouflage better. Submarines, which can be enjoyed on the sea bed in the depths, or even close and operate there, can dhe evade discovery. Were possible even the use of weapons, such as by POSEIDON, the traditional maritime warfare might know a paradigm shift under water. The principle of nuclear deterrence as well.
