I sommergibili atomici russi della classe Borei sono quelli all’attuale stato dell’arte.

Una nota degna di rilievo.

I nomi celebrano il ricordo di eminenti personaggi tutti pre era comunista e tutti nomi dell’alta aristocrazia russa: Prince Vladimir, Prince Oleg, Generalissimus Suvorov, Emperor Alexander III e Prince Pozharsky.

Il Generalissimo Aleksandr Vasil’evič Suvorov, Conte di Suvorov e Principe di Italia, fu uno dei massimi generali russi di tutti i tempi. Combatté e vinse oltre sessanta grandi battaglie, quasi sempre in stato di grande inferiorità numerica. A lui si devono i grandi successi russi nella guerra dei sette anni, nella guerra russo-turca del 1768-1774, ed in quella successiva del 1787-1792.

Chi non conosca la storia russa potrebbe invece restare stupito di vedere il nome dello Czar Alessandro III Romanov. Se è vero che fu un rigido conservatore, e per questo vilipeso e sbeffeggiato durante il periodo comunista, è altrettanto vero che fu anche colui che identificò nella Francia il partner europeo con cui concludere nel 1894 quel trattato difensivo che alla fine esitò nella Triplice Intesa. Era una persona che sapeva guardare lontano, molto lontano.

In ogni caso, resta sempre più misterioso come possa la Russia sciorinare in continuazione sistemi d’arma sofisticati con un budget militare ufficiale di settanta miliardi di Usd all’anno. Il Prince Vladimir sembrerebbe essere costato circa due miliardi di dollari.


Russia’s Borei-class advanced submarines

MOSCOW, November 16. /TASS/. The Project 09552 (Borei-A-class) nuclear-powered submarine Prince Vladimir will be floated out at the Sevmash Shipyard in Severodvinsk in north Russia on November 17, 2017.

Borei-class (Project 09550, 09551 and 09552) submarines are a series of Russian strategic missile-carrying underwater cruisers.

The fourth-generation nuclear subs have been developed by the Rubin Central Design Bureau for Marine Engineering (St. Petersburg) under the direction of Chief Designer Vladimir Zdornov. They are designed to replace the previous series of submarines – the Project 941 Akula-class subs (operational in the Navy since 1981) and the Project 667BDRM Delfin underwater cruisers (operational since 1984). Borei-class submarines are under construction at the Sevmash Shipyard in Russia’s northern Arkhangelsk Region.

Submarine characteristics

The Borei is a double-hull submarine: the crew, the reactor, the turbines, the missile silos and other major systems and mechanisms are housed in the inner hull capable of withstanding high water pressure; the external hull forms the sub’s streamlined shape.

According to data from open sources, the Project 955 submarine measures 170m long and 13.5m wide and a draft of 10m.

The sub displaces 14,720 tonnes in its surface position and 24,000 tonnes in its submerged position. The Borei has a depth capability of 400 meters and can develop a surface speed of 15 knots (27.78 km/h) and a submerged speed of up to 29 knots (53.7 km/h). It has a sea endurance of 90 days and a crew of 107.

The submarine is furnished with a single-shaft steam-turbine nuclear power plant with a capacity of about 50,000 horsepower developed by the Afrikantov Experimental Design Bureau for Mechanical Engineering (Nizhny Novgorod). The submarine’s OK-650V water-cooled and water-moderated reactor has a thermal capacity of 190 MW.

Armament

The submarine is armed with the D-30 missile system (16 launchers of Bulava intercontinental ballistic missiles) and 533mm torpedo tubes. Under the initial Project 09550, the Borei subs should have been armed with R-39UTTKh Bark missiles developed by the Makeyev State Rocket Center (Miass, the Chelyabinsk Region). However, the work on this armament system was terminated after a series of failed tests and the submarine’s design was modified for the Bulava missile developed by the Moscow Institute of Thermal Technology.


Strategic submarines Borei to enhance Russia’s nuclear potential

MOSCOW, December 12. /TASS/. The potential of Russia’s naval nuclear force will grow as more nuclear-powered Borei project submarines continue to be built, the Navy’s commander-in-chief Admiral Vladimir Korolyov said on Tuesday.

“Maintaining the combat potential of the strategic naval force by commissioning Borei-A and Borei-B missile-carrying submarines at the proper level will be the main guideline for the fleet’s development,” Korolyov said at a joint meeting of the coordinating council of veterans’ organizations and the Navy’s command.

Korolyov briefed the Navy’s veterans on the outlook for the development of the Russian Navy under the state program for armaments in 2018-2027. There are plans for building up the combat potential of the general purpose forces by creating ships for operations in the ocean, distant sea and littoral zones, upgrading vessels currently in service, providing advanced aircraft for Russia’s Naval Aviation and coastal missile complexes for the on-shore naval units, and increasing the groups of ships carrying high accuracy weapons.”

As the chief of Russia’s General Staff General Valery Gerasimov said earlier, work is already in progress on creating strategic nuclear-powered Borei-B submarines.

Currently, the Russian Navy incorporates three strategic nuclear-powered Borei submarines (project 955) – The Yuri Dolgoruky, The Aleksandr Nevsky, and The Vladimir Monomakh. They are armed with solid propellant inter-continental ballistic missiles Bulava. Each submarine can carry up to sixteen such missiles. Another five Borei-A submarines are being built. The keel of the last submarine in the series, The Knyaz Pozharsky, was laid in December last year.

Earlier, the CEO of the Central Design Bureau Rubin, which developed Borei, Igor Vilnit, told TASS the project would be worked on further after the series of upgraded submarines Borei-A was delivered.
