Russian "Sever-E" SOSUS systems on sale. Not Top Secret. Why?

Checkout this Russian arms export agency (Rosoboronexport) advertisement for normally Top Secret SOSUS (undersea sound surveillance system) equipment.

Why might Russia broadcast the sale and characteristics (below) of “Sever-E” SOSUS so openly? No other country-company advertises SOSUS equipment for sale - to my knowledge.

See Sever-E's description and graphics on the Rosoboronexport website http://roe.ru/eng/catalog/naval-systems/stationary-electronic-systems/sever-e/ below:

"Sever-E

Static sonar system

Mission

The Sever-E static passive sonar system is designed to surveillance undersea situation for search surface and underwater objects at vast areas, low-noise submarines essentially.

Features

•  search and detection of submarines, surface ships by their sonar fields, with the determination of their coordinates;

• tracking of the detected targets, computation of their parameters (heading, speed, movement pattern);

• classification of the tracking targets by their noise signatures;

•  automated transmitting tactical situation data processed for Task Force targeting by means different communication channels, satellite including.

·     Capabilities

The Sever-E system is capable of detecting ships and low-noise submarines, being deployed along an up to 1,000 km long borderline, at a deep of up to 200 km off-shore and placed at seabed at an up to 1,000 m depth. Coverage zones – 30-30,000 sq. km. Thanks to high reliability of its components the system can operate continuously for 10 years without the need for retrieving the bottom equipment.

Main characteristics

Sonar arrays	8-60
Underwater coverage area (for objects with 0.05-0.1 Pa noise), sq.km	1-9
Surface coverage area (for objects with 0.05-5 Pa noise), sq.km	30-300
Coastal equipment area, sq.m	20-30
Shift crew	2-4
Power consumption, kW	2-4
Service life, years	10

Australia's Future Submarine: US distrusts the French, Huge Cost Blowouts

See Robert Gottliebsen of The Australian's excellent  article “Submarines project a $220bn disaster” of December 10, 2019 at https://www.theaustralian.com.au/nation/defence/submarines-project-a-220bn-disaster/news-story/ed563e92a735dfea84f8ed1adede153b.

Robert Gottliebsen reveals major distrust between the US (which is providing the combat system for Australia's future Attack-class submarine) and the French (who are designing the sub, choosing the contractors, and will oversee its assembly in Adelaide, South Australia).

In the same article Robert Gottliebsen also reveals:

"The Australian government announced in 2016 that it would be paying $50 billion, inflation protected, for the submarines. By 2018 that had blown out to $90 billion. 

At that time, with help, I estimated that the final costs over the life of the submarines, including maintenance etc, would be around $225 billion.

I expected that [Australian] defence chiefs would deny such an incredibly high estimate. Two years later they have now confirmed my estimate, which makes me suspect that the real costs are much higher...."

Thailand to Monitor Myanmar's New-Old Indian Submarine

The Bangkok Post, December 9, 2019 reports the Thai Navy will monitor Myanmar's "new" ex-Indian Kilo submarine - due to become operational in the Myanmar Navy on December 24, 2019.

As India only transfered-gifted? this 32 year old submarine to Myanmar after mid 2019 it is likely that many Indian "advisers" will be aboard. Such Indian advisers (aka "mobile training teams") will be essential for command, control, sonar sensing, engine room operations, weapons handling, etc - just about everything.

The Thai interest is particularly because Thailand and Myanmar share the submarine's proposed operating area - which is the Andaman Sea. Bangladesh, which has some territorial issues with Myanmar might also use its 2 Ming-class submarines to monitor Myanmar's new Kilo.

French & Israeli? Nuclear Tests

(1 minute, 10 seconds into the video above) the English describes France's 18 early nuclear bomb tests. These took place at Reggane and Ekker in the French Sahara between 1960 to 1966. 

According to Lieutenant Colonel Warner D. Farr in a 1999 report to the USAF Counterproliferation Center "Progress in nuclear science and technology in France and Israel remained closely linked throughout the early fifties." Furthermore, according to Farr: 

"There were several Israeli observers at the French nuclear tests and the Israelis had 'unrestricted access to French nuclear test explosion data.'"[6]”

The British conducted nuclear tests in the South Australian desert at Maralinga. Australia could do its own tests...one day.

No Australian Slouch Hats in Submarines!

1 minute 38 seconds in - the side of a slouch hat is pinned up for fashion or to facilitate rifle drill.

2 to 5 min - slouch hats used in Europe and the US Civil War. Slouch hats in action are wide brimmed
                      and unpinned to keep the sun and rain off.

8 min 7 secs onwards - Australian slouch hat (ASH) history.

8m 10s - ASH in Boer War and more detail 

10:07 - ASH in the "Great War" ie WWI. A combination of ASH and other hats at Gallipoli, 1915.

11:22 - ASH in WWII

12:02 - ASH today

I used to wear a slouch hat in the Australian Army Reserve, although I was not a very good soldier (I couldn't do things automatically). Dad was a much better soldier - here wearing an Armoured Corps black beret. 

P.S. There seem to be no biographical details on the Internet for "The History Guy" wonder why?

P.P.S. Submarines lack headroom. So hats are more a submarine movie and/or PR thing? And there is now very little sun - keeping in the shade - worry.
