So if tile de-bonding makes the timeline of introduction irrelevant/void and maturity is measured by tiles that stick, how does that square with the fact that the Virginia class, produced for the US Navy from the early 2000s, are still losing their anechoic tiles? as referenced here

Pretty sure you can't have it both ways! Maybe you could, because hey it's just words they don't have to make sense

As for your statement "not in wide use till the 1980s" I suppose it depends on your definition of "wide use"

I would contend 40 commissioned Soviet subs to be wide use (Given the Royal Navy hasn't produced 40 nuclear subs in 50 years!).

Number of subs referenced from Anthony Tucker-Jones in his book Soviet Cold War Weaponry: Aircraft, Warships and Missiles (ISBN: 9781783032969)
The Soviets used clusterguard on all their fleet submarines after the November class and on all the SSGNs from the Charlie class. So prior to the 80s that would mean all the Victor I and IIs (23 subs) plus a Victor III and all 11 Charlie 1s and 5 of the 6 Charlie IIs so that's over 40 subs in total not counting any of the diesel electrics. Note: A reference with numbers not a sweeping generalisation or a vague assertion to be walked backwards and forwards as circumstance dictates.

Obviously, your definition of wide use can be what ever you choose it to be.
Actually, the Virginia tile issue is new and specific to the Virginia as they are using a new tile/bonding design, and has definitely worsened the acoustics of every sub that has been affected, so this is not as you claim some kind of continuous problem with USN subs. Sturgeon, LA, Ohio, and Seawolf didn't have problems with their tiles. And despite problems with tiles Virginas are still being constructed and deployed, as Soviet subs were with their defective tiles. And as a note on all the Soviet subs with Cluster Guard, this system was considered a failure despite its use on different sub classes as it did little to equalize the acoustics level of any of these Soviet subs compared to contemporary Western subs. Saying these subs all had tiles and then claiming them as an advance on Western subs is about as humorously stupid as saying that slapping some of Nazi Germany's primitive air-cavity tiles on Soviet subs would also count as a Soviet "advance" on Western sub technology. If the technology doesn't work well it doesn't matter how many subs you put it on, it still doesn't work well. And by "wide use" I mean when anechoic tile technology matured at about the same time for many countries i.e. in the early 80s, at which time their use proliferated around the world.

No such claim was made, simply stating the your statement the USN were first is not factually accurate, secondly beyond the historical record even 'modern' subs have problems with de-bonding so acts as a counterpoint to the claim that tiles falling off makes the introduction of the technology somehow invalid. Everything else is your characterisation of the facts as cited without supplying any further facts to substantiate or refute, rather more words to muddy the issue.

So if the Soviets stick tiles on their subs for 15+ years across 40 odd vessels of different classes, 30 years ago, it is "considered" a failure but as the US continues to build and deploy subs that have a similar problem over the last decade it's not? Furthermore, if the Soviet tiles didn't make any appreciable difference to their subs you might have thought they would stop bothering, the fact that even with the tiles they aren't pro-ported to be as quiet as contemporary western subs doesn't say anything regarding the effectiveness, or lack of, of clusterguard simply Soviet subs are nosier than their peers. It would be helpful if there's a basis for the "consideration" that can be shared, considered by whom, when and for what rationale? Care to share the reference so we can all be enlightened?

I am not making any comparisons between Soviet and American technology the only comparison I am making is the contrast in your selective approach to the application of facts in order to support your viewpoint.

Soviet Union applied local version of German WW2 vintage Tarnmatte already on their first class of nuclear subs - Project 627 November. It was effective against sonars in 10-30 kHz range. Second generation of nuclear subs (Projects 670, 671, 667) received thicker tyles effective against sonars in 1-40 kHz range. Third gen received new tyles effective in 10 Hz - 40 kHz range.

The technology was certainly not up to par since the tiles were not only falling off but more importantly even when they were new and not yet debonded they failed to provide acoustic reduction sufficient to put Soviet subs anywhere near on par with Western subs.

So if the Soviets stick tiles on their subs for 15+ years across 40 odd vessels of different classes, 30 years ago, it is "considered" a failure but as the US continues to build and deploy subs that have a similar problem over the last decade it's not?

Actually, both are failures. Did I say somewhere that the Virginia tiles were not failures? As for a "basis for consideration", unless you are talking about something else I have already provided a chart in this very thread retarding the relative acoustic levels of Soviet subs versus US subs, and it confirms what is already widely known, that Soviet sub acoustics were inadequate compared to Western subs for decades, a trend which was temporarily reversed with the improved Akula but once again overshadowed by the Seawolf. Whatever anechoic tile technology the Soviets used prior to the Akula isn't even worth talking about since it clearly did little to nothing to equalize the acoustics disadvantage that Soviet subs chronically suffered.

US aircraft carrier arrives in Vietnam for historic visit as China ties are put to the test

The visit comes at a time when China is increasing its military build-up in the Paracel Islands and seven artificial islands in the Spratlys in maritime territory also claimed by Vietnam

China to develop its first nuclear-powered aircraft carrier...

Please, Log in or Register to view URLs content!



"In February 27th, CSIC released "the high quality micro development strategy for the new era of China Shipbuilding Industry in the official website and official, mentioned the need to accelerate the realization of a nuclear powered aircraft carrier, new nuclear submarines, submarines and other key breakthrough for the navy in 2025 to blue sea strategic transformation to provide high quality weapons and equipment. Military observers say this is the official first confirmation of the existence of China's nuclear powered aircraft carrier program, although it is still in the process of "speeding up the breakthrough."

Right now and in the future US strategy is to choke Chinese Navy like they did with Soviet Union

From Murmansk any Soviet breakout into Atlantic required passing Northern UK waters , UK was very well geographically paced to play this game

From Vladivostok it was Japan who stood in the way

Now Australia, Philippines, South Korea and Japan will try same for China

China needs to do the following, build up islands in South China Sea , these are the unsinkable carriers

Establish foreign military bases the pearls on the string from China to Africa

And thirdly build up Chinese carrier strikes groups 3 of them to face off in each one of its triangles of theatre

By all accounts China is heading in the right direction no war just strategy

That's why the US geopolitical propaganda (media) machine are trying very hard to ratchet up tensions through out the Asian regions as to the need to contain China.

We are continuously fed stream of uninterrupted media coverage to keep brain washing us into thinking that there is this thing called “Chinese threat”

Only people who fear the rise of the Chinese Dragon is the ones who have committed crimes against Chinese in past decades and century’s

China did some big favours to some country’s when China was poor itself now they are standing beside China like a mountain

These country’s can only be too much happy not to mention any names :cool:
