Project 667BDRM/Delta IV

According to Jen Psaki a penguin has been killed by the ruthless action of the evil russkies.

So they made a hole in the ice....and then surfaced next to it.

Im sure its a good reason, but still funny.

IMO it is a test and then they go out to see the results.

Or they want the ice cover them so the torpedo made the hole but also fractured the ice around. Better hidden this way.

They don't need to surface through the hole specifically, explosion shatters and loosens all the surrounding ice in addition to making a hole

The K-51 Verkhoturye (project 667 BDRM Dolphin) is the oldest operational strategic submarine in the Russian Navy. He has been on active duty since December 28, 1984, and next month he will complete 38 years of active service.
For example, the first Borei and submarine K-535 Yuri Dolgorukiy will complete 38 years of active service on December 29, 2050.
The pictures are from this summer.

Zvezda TV just released a documentary about Operation Behemoth https://en.wikipedia.org/wiki/Operation_Behemoth

It looks like the 667BDRM has many more years of service left in it.

"MOSCOW, July 26. /TASS/. The nuclear-powered strategic missile cruiser (APRKSN) "Karelia" project 667BDRM of the Northern Fleet after repairs and tests will be ready for combat service in 2026, TASS reported a source close to the General Staff of the Russian Navy."



Of course, the comments of Western experts are that the production of new Russian SSBNs is slowing down so they have to modernize the old ones.

The comments to that post are retarded.

That Delta IV submarine is from 1989 and is thus younger than most US Ohio submarines currently in service. Plus the Borei/Borei-A programs have been exceptionally successful. For the Borei-A in particular they will be getting one submarine in service every year for the past five years including this one. They also manage to build the Borei-A quicker than the Borei. Despite the Borei being based on partially built Akula hulls while Borei-A is all new construction. Despite most Borei-A submarines being built after 2014 Western and Ukrainian sanctions on sales of military hardware to Russia.

Borei/Borei-A represents the most advanced SSBNs in the world. The submarines have pump-jet propulsion. The Bulava SLBMs fire in a rapid ascent depressed trajectory which makes them harder to intercept.

Exactly, Borey-A is a completely new ship compared to Borey. A completely different hull, different equipment. Probably a new KTP-6 reactor with new turbines, much better soundproofing, better electronics, etc., a different, more modernized pump jet than in 955. There was even another modernization of Borey-B, but it turned out to be unprofitable in relation to cost effect. Now there is some mention of modernization of 955AM and similarly 885AM. Maybe these are some inventions of journalists or maybe they are further modernizations of the successful 885M and 955A series.
The comments of Western experts like Saturnax etc. are funny. How the production of Russian ships with nuclear propulsion is slowing down. How great corruption reigns in the shipbuilding industry in Russia. It may reign like everywhere else, but the submarine industry is doing very well.

In the meantime, we will see how the construction of Columbia goes

I recently read some expert that Borey-A is not better than Ohio

Borei/Borei-A represents the most advanced SSBNs in the world. The submarines have pump-jet propulsion wrote:

With the pump jet it is not entirely clear. It probably depends on many parameters. The Russians installed a standard screw on the 885M and it is also the most advanced attack submarine in the world There are of course opinions that Malachite does not have well-developed pump jet technology like Rubin. However, I think that currently if they had such a need they would have put such a thruster on Yasen M.

Pathetic. So they call launching one Borei-A and one Yasen-M a year slow. There were lots of delays with the initial prototypes of Borei and Yasen but now that the improved modified submarines are in production the build rate has been pretty good.

It is also funny criticizing the Russian naval industry when the US one is nothing short of a disaster. The US has a 200:1 build capacity disadvantage vs China.

Virginia submarine production has already went from one-two a year to one every two years ever since they changed it to add more VLS cells (Block V) and started building the Columbia. And that is with two shipyards.

Retarded hubris.

The pump jet is more silent but only across a narrow speed range. It is better for submarines which do not move that quickly to begin with. For an attack submarine it is actually a bad design choice.

Although France, UK and USA also use them on their SSN. Regarding pump jets and their efficiency and silence I have hear:roll: d so many theories that it is hard to relate.
It is also less efficient at very low speeds. Its main purpose is to reduce cavitation by increasing the pressure in the tunnel and reducing the low-frequency noise created by the interaction of the propeller with the turbulent flow of the boat. It is of course larger, more complicated, more expensive and heavier. Cavitation disappears at a depth of approximately 400m.

In general, extending the service life of the 667BDRM may also be related to plans to increase Russia's strategic potential. The future of the START treaty is uncertain and one 667BDRM ship can increase the nuclear potential by 160 MIRVs.
