Putin warns Russia will be at war with NATO if leaders lift Ukraine missile restrictions

[Donald H]

Why are so many Americans jumping into discussing a nuclear war? All the relevant questions have been answered.

Where there is little discussion and few answers is on Russia's capabilities on conventional weapons!

Of first priority is the popular hunch that Iran has now been armed with hundreds, if not thousands of hypersonic missiles that have demonstrated that the Zionist regime is on borrowed time now!

The Russians can and do track our submarines from submerges listening devices that hear the propeller noise.
Many of our submarines would instantly get knocked out.

Our sensors can't track Ohio's. They are so quiet that they are quieter than the ocean around them. Russian sensiors are far inferior to ours.

US sensors are crap. Anyway, its not just about generation of submarine noises, its more about reflection of outer noises. Submarine, basically, is a bubble of air in water. There is no practical way to prevent reflection of sound and detection by an active sonar. Admiral Rockwell Tory won't allow me to lie.
And the ocean is a noisy place. There is a lot of sounds there. With a good satellite communication and a good computers on the ships (or even on the beach) you can find those reflections. And computers, especially AI recognition of images (visual or sonic) are really good nowadays.
It's not about the "searching for a bright spot" anyway. It's about "analysis of a picture".

As usual you have no idea what you are talking about. No one uses active Sonar anymore since it's a death sentence for the radiating ship/boat. Active sonobuoys are common because it's hard for subs to kill aircraft or helicopters. And US sensors were far superior to the USSR's were and are superior to what China has demonstrated. US subs used to take photos of Russian missile and attacks subs as well as surface ships without the Russians ever knowing the American boats were there.

Whale farts are a continuing concern.

Propellers always have to be noisy.
They are working on an electromagnetic propulsion system, but no one is using that yet that I know of.

You can't knock out active sonar that is dropped in the ocean like a minefield.

It was started with whale songs in 80s, as far as I know. Human ear and even simple electronic could distinguish it's reflection from a hull among other noises. Now, it's almost any loud sound, as far as I know. And there are a lot of loud sounds in the ocean (and the hunters can add some more).

Yes. But active sonars have their weak sides either. They can scary a prey, for example. Whale songs usually doesn't.

There is no ultimate weapon, and there is a counter-measure agaisnt any measure. War is gambling.

You are talking about sonobuoy fields. One minor problem is that the battery on each buoy is only good for a few hours AND neither China nor Russia has the ability to place fields more than a hundred or so miles from their coastlines. Submarine props turn slowly and are designed to eliminate cavitation which is the only thing passive sonar can detect at any distance, plus some modern subs use waterjets rather than props reducing noise still further.

Sonobuoys are floating things. As far as I know Garmonia system is mostly based on automatic bottom stations, with radioisotope power units (work time up to five years), it supposed to be global (but I'm not sure it already is), they can work in passive, active and semi-active modes. Passive mode means that the station is simply hearing, active mode means that it is emitting sound and hear its reflection from the hull (or, be more specific between air-water border), semi-active means that it hear noises (natural and/or artifical) and its reflections from the hulls.
Russia have been placing such stations (early, pre-Garmonia, versions) in American, Canadian and Greenland's territorial waters since sixties. As far as I know, China is working about it right now.
