Russian Pacific Fleet to get Vladimir Monomakh nuclear sub before year end
KRONSHTADT, June 18. /TASS/. The Vladimir Monomakh Borey class nuclear-powered ballistic missile submarine (Project 955) will complete the voyage to the Pacific Fleet before the yearend, Commander-in-Chief of the Russian Navy Admiral Vladimir Korolev told TASS on Saturday.
"This year, Borey will be there, like we have promised," he said.
The Russian Navy has started receiving fourth-generation Project 955 Borei-class (Dolgorukiy-class) submarines recently. It has three of them now - the Yuri Dolgoruky, Alexander Nevsky and Vladimir Monomakh. The Prince Vladimir is due for delivery to the Pacific Fleet next year. Four more ships in the class are due before 2020. Thus, the Russian SSBN fleet will comprise 15 submarines, if the Project 667BDR family is decommissioned.
The Project 955 nuclear-powered submarine armed with Bulava intercontinental ballistic missiles is designed to become the mainstay of Russia’s naval strategic nuclear forces for decades to come.
The Project 955 nuclear-powered submarine can carry 16 R-30 Bulava solid-propellant intercontinental ballistic missiles with a range of more than 8,000 kilometers (4,971 miles). The Bulava intercontinental ballistic missile features multiple independently targetable reentry vehicles.
The Project 955 nuclear-powered submarine is equipped with an escape chamber designed to accommodate the entire crew.

Russia's Dmitry Donskoy sub to participate in testing of upgraded Bulava missile
MOSCOW, June 21. /TASS/. The heavy nuclear-powered submarine The Dmitry Donskoy will stay operational at least till 2020 and participate in the testing of upgraded inter-continental ballistic missile Bulava-M, a source in the military-industrial complex told TASS.
"The question of scrapping The Dmitry Donskoy will not be raised till the end of 2019. It will remain part of the Navy and be used for pop-up and flight tests of the upgraded Bulava missile, being developed at the Moscow Institute of Thermal Technology," the source said.
Bulava was designed to arm the strategic nuclear-powered Borei submarines of the upgraded project Borei-A, the source said.
TASS has no official confirmation of this.
Earlier, a source in the Russian defense industry said The Dmitry Donskoy would be used for testing missiles and other technologies till 2017.
It is the sole nuclear powered submarine of project 941 (Akula) still in service in the Russian Navy. In 2003-2010 it carried out 14 test launches of the Bulava missile. Half of them were successful.
