The Akula boats are the quietest submarines the Russians have ever built.

They use a teardrop-shaped double hull construction. The living spaces, torpedo tubes, and most of the machinery are within the stronger inner hull. The ballast tanks and specially adapted gear are located between the inner and outer hulls. This gives it much greater reserve buoyancy.

Anechoic tiles are fitted on casings and fins to absorb the waves of active sonar.

At low speeds of 5-7 knots, the Akula is even quieter than the improved LA class.

Russkie “Bear” Bombers in the Alaska an Arctic areas and subs in the Gulf? I’ve also read (conspiracy InfoWars site) that Spetsnaz SF troops are already on US soil, coming over from Canada. I’m not in that “black helicopter crowd”, but it makes me wonder what 0bummer&TheRegimeFromHell’s up to, if anything or is it just coincidence or BS. DHS ammo stockpiles, riot gear etc etc etc. Nah... nothing to it.

Now we know why Obama stopped us from drilling in the gulf.

You have to understand the way the submarine warfare game is played. Were they there? Maybe, sure, why not? We certainly have sent (and probably continue to send) subs to patrol right off their coastlines.

The real questions are, was the sub detected or not, and if it was detected, was it trailed or not? These are questions we will never know the answers to for sure, because they will never, ever be admitted in public.

One way of looking at it, you want your adversary to come over and patrol - as long as you detect them and can follow them. That allows us to establish their operational patterns, from which we can infer capabilities. Even better if they don't know they were detected and tracked. Otherwise, they may come over and do something screwy, giving you the wrong impression, or they'll change tactics, etc. The upshot is, you want to collect as much information as possible while giving nothing, nothing away in return.

How does anyone know that the sub was not in the Gulf of Mexico?

Under Obama, the Pentagon has lost all credibility. If they say “no” the truth is very probably “yes”.

Lately, the Pentagon is as flexible as Barack and will bend over more so if it gets reelected.
If the “Generals” ever take their oath to the Constitution seriously....

The Pentagon denies.......they tell us what Bam tells them to tell us....... Meanwhile what’s the latest on the reports that they have a scenario involving the T-Party IN the USA?

I have to say, your comments are similar to what one might find on a cereal box. It's not that most of them are false, it's that they're so generic that they add little to this story.

Most modern subs built in the last 30 years utilize a "teardrop-shaped hull," and yes, most of the major machinery, and certainly the living spaces are within the inner hull. Anechoic tiles are routinely used on submarine surfaces to absorb active sonar.

Submarine construction, quieting programs and sensors are much more sophisticated than some of the features you mention. Dampening machinery and noise goes much further than simply using a double-hull coated in sound-absorbing tile. What about flow noise? What about sound associated with the propulsion system; e.g., the propeller?

Being quiet at 5-7 knots is great, but what happens to the sound profile if the submarine has to go at speed, such as when they're trying to evade a torpedo? Also, it would be interesting to know how you might be knowledgable about their level of sound. Also, despite their superiority throughout the Cold War, the LA class has been surpassed by the Seawolf and Virginia class submarines (though I'm sure the Obama administration is doing what they can to stop the program as much as they can.) These are subs that can run quiet at speeds in excess of 20 knots.

I believe it because Obama’s responsibility would have been to sink the damn thing.

A responsibility Obama is singularly unequipped to execute.

I worry far less about a Russian nuclear powered submarine being off our shores, than I do about the Kenyan presently contaminating our White House.

If the Russian’s were actually there, they were likely testing, training and/or sending us a message, unlike Obama and the democrats that are destroying our country.

Regardless, I would trust the word of Pravda far more than Obama’s Pentagon.

You know your stuff - so what's your best guess - were they in the Gulf or not?

Wow!

I went to St. Pete Beach several times and never saw anything but some ugly tattoos.

Pentagon Denies Reports of Russian Sub near U.S.

Of course they would!

yeah, and a lot of the credit goes to Toshiba who sold sophisticated, nine axis milling equipment to the Soviets along with the computer control systems to machine their screws...
