Russian latest Borei-A nuclear-powered sub completes state trials

The most advanced nuclear-powered submarine Knyaz Vladimir has arrived at the Northern Fleet’s Belomorsk naval base

MOSCOW, November 21. /TASS/. The most advanced nuclear-powered submarine Knyaz Vladimir (Prince Vladimir) has completed the cycle of state trials and arrived at the Northern Fleet’s Belomorsk naval base, the Fleet’s press office reported on Thursday.

"The latest Project Borei-A strategic underwater cruiser Knyaz Vladimir has completed state trials at the Northern Fleet’s combat training ranges in the White Sea and arrived in Severodvinsk," the press office said in a statement.

At the wharf of the Northern Fleet’s Belomorsk naval base, the cruiser’s crew was welcomed by Base Commander Rear Admiral Konstantin Kabantsov and CEO of the Sevmash Shipyard (part of the United Shipbuilding Corporation) Mikhail Budnichenko.

On October 30, the crew of the Knyaz Vladimir test-fired a sea-launched Bulava intercontinental ballistic missile from the White Sea towards the Kura range in Kamchatka in the Russian Far East and also held torpedo fire against an underwater and surface target.

Aside from the trials of the sub’s sea-launched weapons, the shipbuilders checked the operation and the reliability of all its systems, mechanisms and equipment and made measurements of the noise level and the underwater cruiser’s other special parameters.

The Knyaz Vladimir is the improved Project 955A strategic missile-carrying underwater cruiser and represents the fourth generation of nuclear-powered subs built for the Russian Navy.

Compared to the first three Borei-class submarines - the Yuri Dolgoruky, the Alexander Nevsky and the Vladimir Monomakh, the Knyaz Vladimir is less noisy and features improved maneuvering, depth and armament control systems.

Source: two submarines Borey-A laid on the day of the 75th anniversary of Victory (9 may 2020) russia

MOSCOW, Nov 29 - RIA Novosti. The ninth and tenth nuclear submarines of the modernized project 955A (Borey-A) are planned to be laid down on May 9, 2020 and transferred to the Russian Navy in 2026 and 2027, a source in the military-industrial complex told RIA Novosti .
"The laying of the ninth and tenth Borea is scheduled for May 9, 2020. The transfer to the Navy is in 2026 and 2027," the source said.

The source noted that the names for the new submarines have not yet been determined.

Earlier, Deputy Minister of Defense of the Russian Federation Alexei Krivoruchko told reporters that the Ministry of Defense had planned to supply the Navy with two nuclear submarines of Project 885M (Yasen-M) and two nuclear missile carriers 955A (Borey-A). Thus, the number of "Boreev" will be increased from 8 to 10 submarines.
Three Boreas have already been built and are part of the fleet: Yuri Dolgoruky, Alexander Nevsky and Vladimir Monomakh. The fourth submarine, "Prince Vladimir," is undergoing sea trials.

That would be 10 Boreis and 9 Yasens

Hopefully they keep at it, it's nice too see the fleet going into double digits for a change without constant flip-flopping and starting over from scratch

Thanks

It's way more difficult to put all the news that keeps this forum going(George1). Or give great explanations like Gazputin, GarryB, etc...and of course the giant Mindstorm...oh and Arrow too for the laughs.

I think when a product is working keep buying, the r&d for the new SSBN can wait a little, the problem is when they buy like Lada submarines etc...

The 24 tubes of the Ohio class and 20 tubes of the Akula class were from a time when there were no restrictions on how many missiles or warheads you could have so having more on each sub just meant for every new sub you put in to service meant more missiles available for use if needed.

These days with new START.... right now Russia could have 2 and a half Akulas with 500 warheads in 50 missiles, while the US could have 3 and a half Ohios with 504 warheads in 84 missiles.

With Borei having 16 launch tubes and 6 warheads per missile that is 96 warheads per boat so just over 5 Boreis is legal these days.

That large truss arrangement on the bow is apparently related to some calibration activities for her hydro-acoustical sensor complex (?). Anyone have any info on it? I've never seen anything like this before.

Almost looks like an iron sight that you use a periscope to aim down to make sure the barrel is calibrated properly.... Twisted Evil

An OPK source tells TASS that the Russian MoD will sign a contract for two more Borei-A SSBN in August, which will be laid down at Sevmash in 2021. These will be the 9th and 10th Borei SSBN

Actually these two would be 11th and 12th Borei SSBNs

It looks like next Borei SSBN that will be laid down will be called Rurik https://en.wikipedia.org/wiki/Rurik

Apparently Pacific Fleet wanted to name a frigate after him but Navy had already reserved the name for a boomer

I have been wondering when this guy will get his own boat

I think he would appreciate the fact that vessel named after him will be packing enough heat to kick-off Ragnarök with him being Viking and all.... Cool

Forgive my ignorance but what's the difference between that prop arrangement and a waterjet propulsor?

Most noise is generated by blade tips

This setup is supposed to minimize that noise since tips are covered snuggly by shroud without much space between

Wow this is rim driven thruster. Electric motor driving fan without a shaft consiting of the outer shell as a stator and then fan as rotator with a bearing against stator. It can be very quiet drives in the future without additional drive shafts etc.

This is the Borei thread, not the thread for your superiority complex against Russia by touting China as the next big thing.

When China gets a SSBN with Borei's capabilities you let me know.
