The High-Tech Hunt for Russian Submarines

The U.S. Navy is engaged in a technology-fueled game of hide and seek, hunting for stealthy Russian submarines like the Krasnodar, a.k.a. "The Black Hole." Video/Image: George Downs/WSJ.

“Low magnetic steel that makes it harder for sonar arrays to detect them” Magnetism and sonar are unrelated. This type of steel is used to avoid magnetic sensors, it’s also used in mine counter-measure vessels to avoid triggering magnetically triggered mines.

They forgot to mention that when deployed a few months back, Russian fleet command announced that it was on its way. Krasnodar sailed on the surface most of the way, then it was announced that it was going to do a mission and with a US navy battlegroup watching it the Krasnodar disappeared. A few days later it fired cruise missiles near Syria and then headed home. The search group included almost every type of tracking equipment that NATO operates....

One of the statements was misleading: One class of Soviet (now Russian) submarine used titanium in the hull to greatly reduce its MAGNETIC signature. Magnetic Anomaly Detection used the field change in local magnetic field to find steel-hulled boats. MAD has limited range/sensitivity... not even sure it's used now. Stainless steel also has a reduced signature. The video somehow linked an acoustic or sound response to the hull material. Ocean thermal and salinity layers are an important resource for hunted submarines as sonar will reflect off the interface... the sub can hide below. A senior petty officer suggested in the 1970's that on a perfect day - good water, good weather and equipment working well - the game was still 60/40 in favor of the submarines. Computer processing has advanced orders of magnitude so pulling a reliable signal out of background noise is vastly improved.... but it still works both ways. Carriers - the ship itself - does not hunt submarine but its helicopter group does.
The Germans and Japanese have some of the "quietest" boats in that they've integrated fuel cell and advanced batteries into their designs.

Now if they could just locate Argentine submarines! But that may be too much to ask for...

Meanwhile the sweds defeated the entire US navy with one

[melcanuck]

Think the Swedish Navy managed to out-hunt the US submarines in some naval games....

[Pawglovr]

I think you'd have to find MH-370 1st before you can find a Russian sub 😊

[dspates]

The Mark 48 ADCAP torpedo was specifically designed to counter deep diving submarines. You don't need the submarine to go deep to fight just the weapon.

You dont hunt submarine, submarines hunt you, you only sometimes get lucky that you find out some submarine hunting you and can make an escape before it reaches you

[ThyMajesticOne]

Wow. Military lesson for children.
Destroyers/submarines hunt submarines, not carriers. A US carrier taskforce have both destroyers and nuclear submarines(no need to surface) incorporated in them.
What about the thermal layer?
...and MAD, Buoys, active/passive sonar, etc etc...

Very unbiased real world reporting from the WSJ. Interesting!

[imyafamilia]

And US navy failed to detect Russian sub. Russians also making nuclear drone kamikaze sleepers subs. Think aboot et!

[shwhitebuffalowoman]

Love it! I used to play battleship and win.

Nice video! They forgot to mention MAD (Magnetic Anomaly Detector), it uses any variation in Earth's Magnetic field to locate Submarines!

[detailingdiaries]

No mention of SOSUS, or tower sonar arrays, or the fact that aircraft carriers are not deigned to hunt subs etc etc etc.

[davidchristensen]

Why would the USA say they can track this sub. It makes more sense to not say a word on if you can track them or not. None of answering here on YouTube will have a clue if the USA can or can’t track this sub. Anyone that comes here and says they know is just an out right liar. I find it interesting after all these year Russia finally is capable of making a sub this quite. We will see. If the USA tracked this sub from the middle of the Atlantic until it’s missile launch the USA will not say a word.

[haimbenavraham]

It might be costly but maybe worth it. To establish sensors on the ocean floor near sensitive land areas.

[bradleyshimels]

There are sonar detection systems available in the US Navy arsenal that can easily find a hidden sub. Russian or any other country .Not as hard as article shows!

10/10 got a navy recruitment ad on this video

I thought I heard the new Boeing Pegasis, converted B737 into an antisubmarine hunter, can detect submarines from an altitude of 41k feet.
