The following is new to me:
"SOSUS has also been used by law enforcement personnel, most notably in drug interdiction efforts for over-water supply routes from Central and South America."

Such "law enforcement" may include the US Coast Guard (allerted by SOSUS, other sensors and units) deploying snipers, from helicopters. The snipers disable low profile "drug subs" or boats by aiming at their motors or other non-personnel gear.

Data is transmitted from the ship to an acoustic processing site ashore via satellite. Stalwart class ships were designed to search for foreign submarines. Several have since been assigned as drug interdiction forces. Victorious class ships are built on a Small Waterplane Twin Hull (SWATH) design for stability at low speeds and in rough waters.

Hi Pete,
Here you have another sensor
"The U.K. Royal Navy's Trafalgar class attack submarine HMS Talent has arrived in the British territory of Gibraltar sporting curious new sensors on either side of its sail. We can say with near certainty that these are additions to an existing system designed to detect enemy submarines without the use of sonar that first appeared on the boat in 2019."

They have their terminology wrong. SOSUS looks across oceans and need to be on the edge of continental shelf. The SOSUS would need to be in Europe. See https://en.m.wikipedia.org/wiki/SOSUS.
Thanks /Kjell
Yes I noticed The Drive's, Feb 2, 2021 article:
"Royal Navy Submarine Appears In Gibraltar Equipped With Enhanced Wake Detection System"
at https://www.thedrive.com/the-war-zone/39055/new-wake-detection-sensor-spotted-on-royal-navy-submarine-as-it-pulls-ito-gibraltar
That article continues:
"The U.K. Royal Navy's Trafalgar class attack submarine HMS Talent has arrived in the British territory of Gibraltar sporting curious new sensors on either side of its sail. We can say with near certainty that these are additions to an existing system designed to detect enemy submarines without the use of sonar that first appeared on the boat in 2019.
...It's not clear how long Talent has had all three of these sensor arrays installed together.
As for what these sensors actually do, they are designed to detect other submarines beneath the waves via the changes in water density that they leave in their wake. These systems have historically been almost exclusively associated with Soviet and now Russian submarines. In that country, they are most commonly referred to collectively as examples of a System Obnarujenia Kilvaternovo Sleda (SOKS), or Wake Object Detection System.
There have also been reports in the past suggesting that certain SOKS variants could be able to detect trace amounts of certain chemicals in a submarine's wake, including from temporary anti-corrosive coatings flaking off or byproducts from oxygen generation systems. Detecting minute increases in radiation levels from the reactors on nuclear-powered boats, such as the Trafalgar class, or elevated water temperatures from a submarine passing by, may also be among their capabilities..."
Thank /Kjell

Hi David Candy
True. But on an international level SOSUS is no longer the exclusively US, UK (and I daresay Canadian) long range North Atlantic, North Pacific hydro-acoustic system.
Systems developed by other major powers (Russian and China) are also loosely described as "SOSUS" without specifying their Russian (and probably secret Chinese) system names.
As you point out the US has replaced the SOSUS label with a more nodal/flexible, including non-acoustic tech, Integrated Undersea Surveillance System (IUSS) "Advanced Deployable System" at https://en.wikipedia.org/wiki/SOSUS
Also at http://www.iusscaa.org/history.htm and the surprisingly publicallly accessable US Navy website (given the subject matter) https://www.csp.navy.mil/cus/About-IUSS/
So yes IUSS doesn't require the old SOSUS high voltage electrical power coaxial cable technology, with data displayed via hundreds of slow hardcopy printers with 1,000s of men to man large landfall of cable coastal stations.
More on this is on my blog https://gentleseas.blogspot.com/2019/01/possible-sosus-rapfds-arrays-western.html

You might find this article about SOSUS interesting

For SOSUS history
https://www.usni.org/magazines/naval-history-magazine/2021/february/66-years-undersea-surveillance
As I looked at the usni article I was amazed how labour intensive “walking the beams” operators and isolated site support staff services must have been. They'd also need to run shredders or furnaces day and night to dispose of all that "Gram Writer" paper see https://www.usni.org/sites/default/files/unnamed_0.jpg
Compared to old Soviet systems America's lead in labour saving devices by computerizing this system must have been a huge advantage.
Large USVs and LDUUVs dragging the Surveillance Towed Array Sensor Systems (SURTASS) will make a big difference.
CAPT Joseph P. Kelly, USN (1914-1988) "Father of SOSUS" https://www.csp.navy.mil/cus/About-IUSS/Father-of-SOSUS/ had an amazing career.

Pete
