MOSCOW, November 2. /TASS/. The eighth Borei-class nuclear-powered submarine will be laid down at the Sevmash shipyard in Russia’s northern town of Severodvinsk on December 23, the submarine will be named Knyaz (Prince) Pozharsky, a source in the defense industry told TASS.

The Knyaz Pozharsky submarine will be the last of the eight Borei-class submarines and the fifth of the advanced Borei-A-class ones.

Three submarines built under this project have already been turned over to the navy. Each submarine carries 16 Bulava intercontinental ballistic missiles.

The Knyaz Vladimir submarine, laid down in 2012, is being constructed under the advanced project. Project 09552 Borei-A subs are characterized by better stealth capabilities, more advanced electronic equipment and more comfortable conditions for the crew.

In 2014, two submarines, Knyaz Oleg and Generalissimo Suvorov were laid down while in 2015 the construction of the Emperor Alexander III nuclear submarine began.

Borei project

Borei personifies the northern stormy wind in the Greek methodology. However, the operational area of these strategic submarines is not limited only to northern latitudes as these underwater missile cruisers are capable of operating in any part of the planet. Their seaworthiness is actually unlimited.

 Borei-class submarines have become a breakthrough project for today. Borei developers have managed to achieve the submarine’s maximum stealth capability by using a hydraulic propeller placed in a special ring nozzle and operating like a water pump receiving a streamflow.

The submarine’s hull is assembled of blocks while all its equipment is mounted on shock absorbers. They separate each block from the hull, thus further reducing the vessel’s noisiness level when a submarine moves under the water.

Besides, all the submarine’s sonars are united into a single automated digital system, which both locate targets and, for example, measure the ice thickness and search for ice openings.

According to some data, the sonar system mounted on the Yury Dolgoruky submarine excels similar equipment installed on US Virginia-class submarines by the range of its operation. This means that Borei-class submarines can detect targets under the water while staying out of reach of sonars used by any of the enemy’s warships. Submarines of this class are armed with Bulava intercontinental ballistic missiles, which are their basic combat striking power. The performance characteristics of Bulava ICBMs are not disclosed and constitute a state secret.
