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

    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.

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

    "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. Laughing

    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 Laughing

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

    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 Very Happy 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.

    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. Very Happy 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.

    In total they had to extend it to 140m. Virginia block V costs over 4 billion USD. It has equaled the number of cruise missiles but can only carry Tomahowk or Harpoon. Yasen M Kalibry (soon with a range of 4500km) some sources say 40 units, or 32 units 33M22, P-800. It has 8 or 10 torpedo launchers plus another 30+ in reserve. The only problem for VMF is that the US plans a total of 66 of them with the previous blocks

    I don't know. They still have crews on over 20 Los Angeles ships. The question is of course whether they will build that many. Costs are rising and here you also have to build a fleet of SSBNs.

    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.

    With the new START treaty on hold then there is no point retiring anything to comply with it.

    The more Russia has in excess of what the new START treaty allows the more likely the US will be wanting to go back to it or create a new agreement to take its place.

    Until then having more available ready to fire missiles is a good thing even if they just allocate such a sub to attack targets in Europe or the Middle East or Asia Pacific.

    The only problem for VMF is that the US plans a total of 66 of them with the previous blocks

    They were going to make 1,500 F-22 and 200 B-2s... and then reality hit and the numbers were slashed.

    Edit: they were also going to make 100 Zumwalt destroyers and hundreds of LCS craft and they are having problems with the frigates they did pick to replace the LCS because they are getting overweight and so they might need to increase propulsion which will make it more expensive of course... and add delays.

    As their economy shifts to a new reality where they can't just print money to solve their problems because it is no longer the preferred trading currency and of course their new habit of seizing assets and stealing from other countries, which is going to destroy trust in their stewardship of other countries funds and assets they are going to have to start inflicting austerity measures and budget cuts to themselves... not to mention start some communist ideas like rich bastard tax which will send the richest people in the US scattering to the world... but then they can just nationalise everything they leave behind or can't take with them and start working and making sure the profits and benefits from companies in the US go to the US as a country instead of the few families that used to own everything that was profitable.

    I don't think their defence budget is going to climb much in the future... in fact I think they are going to start bringing a lot of their military home because it doesn't benefit their bottom line like it used to.

    The military got more expensive than they trade and security it generated for the US and her allies.

    Costs are rising and here you also have to build a fleet of SSBNs.

    MIC costs in the US have been corrupt for decades and that is creating a decline in quality and performance of their systems... no longer state of the art... but it costs the same as state of the art does.
