      The Husky submarine will completely merge with the noise of the world ocean, USC said

      https://ria.ru/spief/20180525/152135...most_popular_1


      I wonder what does completely merge with nose of the world ocean means ? Its cryptic ....what does the noise of Akula and Yasen is then ?

        Looks to me the Husky will try to achieve what Ohio class could. It was stated that Ohio class is the most silent boat, with noise level of some 90dB which is the same as sea noise background.

          When India commisioned the last of the Kilo class in late 90's it was mentioned by them that these kilo is very quite with noise level equal to background noise of sea.

          I think background noise of sea is a very vague statement

            Ohio is ancient, there is no way their bar is that low.

              Or it is.
              If you read Tom Stefanick's book, "Strategic Anti-Submarine Warfare and Naval Strategy" You'll find this chart.

              The way to read it is the top corner of the bar is the "high end" of the estimated noise level while the lower end is the "low bar" So the Ohio is about 90-110 dB. Any lower than Ohio is basically a diminishing return as the detection range of passive sonar in that region is basically same as the size of the submarine.

              Why i took the book seriously ? Because it's sourced and the author have well scientific background and support. (Granted it's 1980 book but the science is still relevant today)

              The book in question if you want to review :

                Boomers tend to be much more high-end than attack subs and may use solutions which just would be too expensive to execute in a series of fleet boat. Also their performance requirements are much less than attack subs.
                When those French & Brit boomers collided, they apparently had no clue about each other prior to it.

                  In fact, they had no clue about each other after it, either - IIRC the two navies only pieced together what had happened after each had their sub report collision damage.

                    KADEX 2018: UAC Showcased Maritime Patrol Variant of Il-114

                    http://www.navyrecognition.com/index...of-il-114.html




                    Russia's United Aircraft Corporation (UAC) has unveiled the Ilyushin Il-114MP maritime patrol aircraft (MPA) based on the Il-114-300 airlifter during KADEX 2018 defense exhibition in Kazakhstan.

                    The Il-114MP has a take-off weight of 26,000 kg and features six-strong crew, including two pilots and four operators. The aircraft patrols an area with a radius of 300 km at an altitude of up to 8,000 m during 12 hours. The MPA is powered by two Klimov TV7-117ST turboprop engines with a power output of 3,000 hp each. The Il-114MP has a practical flight range of 4,500 km. The aircraft requires 950 m to take off and 530 m to land.

                    The Il-114MP can be fitted with the Kasatka-S search-and-targeting system, which comprises an information management subsystem, a multipurpose radar with an active electronically scanned array, a radio sonar subsystem, a magnetometer, and an optical-electronic turret with a thermal imager, a TV channel, and a laser rangefinder. The system allows carrying of two Kh-35E anti-ship missiles and a GSh-23-2 23 mm automatic cannon. An Il-114MP MPA fitted with the Kasatka-S can detect a target at a distance of 120 km.

                    A source from the Russian defence industry said the Kasatka system had been intensively tested in various regions of Russia, including the Arctic.

                    At the MAKS 2015 international aerospace show, the Saint Petersburg-based Radar MMS company unveiled the Il-114LL (LL for flying laboratory) aircraft fitted with the Kasatka-S system. Radar MMS has developed several variants of the Kasatka for various air platforms, including light and medium utility helicopters (Kasatka-V and Kasatka-VB, respectively), medium and heavy MPAs (Kasatka-S and Kasatka-SB), unmanned aerial vehicles (Kasatka-BP), and aerostats (Kasatka-A).

                      When you dive to a certain dept, you will enter a Termic layer that will mask your sub. The decibel noise is slightly higher within this layer.
                      I suspect this is why they mention "merge with noise of Ocean" means.
                      When you get a Sub that is now below a value of sound decibel, it will mask itself within the Termic level of ocean.
                      But as always, there is the topic of distance between Sub and Anti-Sub surface ship.

                        beautiful ship, but they will need more if they intend to teach Norway a lesson!
