"Suicide bombers" of the "Black holes" project 877 and 636
TASS, October 12:
RBC:
Everything that is happening now in the relationship between Russia and Japan, more and more begins to resemble 1903.
Things are heading for war.
And the parallels between 1903 and 2021 can be traced not only in our "strange" foreign policy line, but also in the misunderstanding of the real military threat by many military personnel and the need for forced preparation.
Last week, Channel One on the Chasovoy program released a very good film about the coastal submarine of the Pacific Ocean. fleet - diesel-electric submarine (diesel-electric submarine) B-187 "Komsomolsk-on-Amur" (laid down on May 7, 1991, the acceptance act was signed by the Navy on December 30, 1991, on January 27, 2017, after a long repair with modernization, returned to the Pacific Fleet) ...
Video about the B-187 "Channel One" 2019.
Below are screenshots from both videos with comments.
The central post of the modernized submarine, on the left, a new BIUS "Lama" is highlighted, on the right - a new digital rack of the submarine steering system.
BIUS "Lama" close-up from the video of 2019.
New equipment in the navigator's cabin (at the same time, the question of installing the Appassionata digital navigation complex, which is standard for the new "Warsaw women", remains open).
A new digital control system for general ship systems (SU OKS) has been installed:
Actually, the reason for replacing the old relay control system of the OKS and the analog (on selsyns) steering system is obvious - the exhaustion of the resource and malfunction of the old systems and the impossibility of their serial production, respectively, the boat received new automation systems.
It is extremely important to replace the old hydroacoustic complex (GAK) MGK-400 "Rubicon", developed in the late 60s - early 70s, with a new digital sonar MGK-400V (for more details see the article "Rubicon" of underwater confrontation. Successes and problems of the MGK-400 hydroacoustic complex ").
Hydroacoustic deckhouse for diesel-electric submarines of project 877 with the old state joint-stock company "Rubicon". It is not for nothing that these submarines are called "Black Holes".
Hydroacoustic cabin B-187 in 2019 (screen from the video of Channel One) with the new MGK-400V SJSC.
In the filming of 2021 in the sonar cabin, the loss of one strut (there are two of them) of the SAC is found. I would very much like to hope that it is being repaired or modernized and will be installed on the B-187 in the very near future, because its absence significantly reduces the full potential of the MGK-400V digital SJC.
SJSC MGK-400V is very, very good in terms of its technical level and has a large-sized main antenna of the SJSC with a large energy potential (noise direction finding).
However, an extremely acute problem is that the main antenna (bow) has a frequency range limited in the low-frequency region and a "blind sector" in the stern. The inset in the screen shows the registration data of a real low-frequency signal "illumination", the frequency band of which is outside the operating range of the MGK-400V nasal antenna.
That is, the enemy is able to "highlight" our submarine, including covertly (subject to power limitation and the use of noise-like signals) for it. And today not only special hydroacoustic reconnaissance vessels are capable of this, but also such massive means of searching for submarines as active radioacoustic buoys (RGAB) aviation... In conditions of such illumination, even an absolutely low-noise submarine is displayed like a fly on glass.
Let me emphasize that our submarine may not even suspect about this. The expression "a cat stuck in a felt boot" will be absolutely accurate here!
All these problems are successfully solved by an extended flexible antenna (GPBA), which provides both low frequency control and, in fact, a circular, 360-degree observation. The phrase "no shadow zones" from the picture on the Spanish acoustics website shows this clearly.
Yes, the efficiency of detecting low-noise targets at low heading angles of the GPBA is low, but it is ensured by the detection of such objects as torpedoes (and at considerable distances), and the same low-frequency signals of "illumination" (that is, our boat can understand that it is being guided and prepared to attack ).
As a matter of fact, this has already been written many times, for example - "Anti-torpedo catastrophe" of the Russian fleet ".
It is of interest to discuss the issue on one of the specialized resources. The civilian asks simple and logical questions, in the answers to which the "corporation" (two people answer: the "insider lobbyist" mentioned in the article "PK 22160" and an employee of the organization known as the "Central Research Institute of Shipwreck") ( link):
A simple and logical question ...
It is not even the absolute ignorance and illiteracy of the representative of the so-called "military science" that is striking, but the absolutely boorish style of response. Let me emphasize - on absolutely sensible and logical questions of a civilian.
What kind of "cooling"? The same BIUS "Lama" has natural convective cooling - due to low power consumption (and GPBA is even less)! "Don't like" the UPV (GPBA setting-sampling device)? Do not bet - as it is done on a good half of the western diesel-electric submarines. In the photo on the Dutch diesel-electric submarine, the GPBA mount is permanent (at sea) through the "clip", with the exit to the sea and return, it is manually unwound by the personnel.
In short, this is all a lie!
The submarine needs GPBA all the time, not to mention the fact that the underwater autonomy on one charge of the "Warsaw" is many times higher than the one declared by the "insider-lobbyist". On charging the GPBA, all the more so in no case should you reel off - it is on the charge that the GPBA is just very, very necessary and important (controlling the situation by 360 degrees with the base of the GAK antenna partially deaf from the operation of diesel generators)!
Price? Is it "not worth" money to build an almost incapacitated submarine?
Without GPBA, the submarine turns out to be deliberately defective and incapable of fighting against any serious enemy. Refusal from GPBA for “financial” reasons is not just “saving on matches”, it is “a mistake much worse than a crime”!
Well, and completely false is the thesis of the alleged "failure of the construction deadline" because of the GPBA.
It may be said that this is a "forum", this is an "Internet". No, everything is much worse - a similar rotten "argumentation" (in quotation marks) is contained in the documents and reported to the military-political leadership.
There is no GPBA not only on the modernized "Komsomolsk-on-Amur", it is not even on the "newest" (just put into operation) "Magadan"! The war is "not expected", but for the parade "and so it will come down."
But an even more disastrous situation is shown with weapons "Komsomolsk-on-Amur".
About the antiques of our torpedoes (lagging behind the modern level for more than half a century) has been written many times. At the same time, there are positive changes, new, jam-resistant torpedoes still went to the fleet (albeit with a number of shortcomings).
However, the B-187 that came out of the modernization never received new weapons (missiles and new torpedoes), the video clearly shows the old design of the rear covers of torpedo tubes (TA) without AERVD data entry units.
That is, there is a BIUS (capable of firing new torpedoes), but again "saved on matches" - on entering data into the TA!
As a result, the modernized "Komsomolsk-on-Amur" is able to use only extremely ineffective in modern conditions "torpedo junk", taking into account that the boat has a mine ammunition (from anti-submarine mines PMR-2). The video clearly shows that several torpedoes are only on the side lower racks, the rest of the ammunition is PMR-2.
Note. The very fact of filming and publishing a video from the torpedo deck of a submarine of the Navy's combat personnel is puzzling, in view of the specificity and importance of such information. According to the author, a public demonstration of the loading (option) of ammunition on the torpedo deck of the submarine, if possible, is only after several years have passed since the shooting and without specific reference to the carriers. And these are not trifles, despite the capabilities of the same satellite reconnaissance, the specific layout of the ammunition in the compartment itself is hot information, that is, it actually informs the enemy about the real combat capabilities of the submarine in a given situation.
It is worth noting that there is no particular sense for diesel-electric submarines in this particular case in the mine version. As there is no point in finding diesel-electric submarines in Vladivostok, their redeployment there from Kamchatka was, of course, a wrong decision.
PMR-2 is an exclusively anti-submarine mine and has long been outdated, having a huge visibility for sonars and a small affected area. The video shows the shooting of torpedo tubes with air ("bubble"). The extremely low secrecy of such a shot is obvious, which is aggravated by the need for a large number of such shots for a short time in a limited area for setting mines.
It will be appropriate to recall here that Japan has highly developed systems for illumination of the underwater environment, including stationary sound direction-finding stations with very high capabilities. Accordingly, our diesel-electric submarine with them is obviously practically a "suicide bomber" - and without the prospect of causing any serious damage to the enemy.
Why is it still (with all this in mind) PMR-2 in the B-187 ammunition load?
Apparently, due to the disastrous state of the old torpedoes (let me remind you that the last high-speed nuclear submarine of project 705K - B-123 served after repair in the "mine loading version", because there were simply no old torpedoes for it).
Well, there is a very bad factor that is far from always adequate to the requirements of higher command bodies (for example, the General Staff) about the presence of a part of the carriers “in a mine version”. The fact that in this version (with our obsolete mines) the real efficiency of the submarine is practically zeroed, the relevant operators, it seems, do not know ...
Anti-torpedo protection (PTZ)?
It's also very bad there - more details "Anti-torpedo catastrophe" of the Russian fleet ".
Diesel-electric submarines of project 636 are armed with SGPD: drifting device PTZ "Vist-2" (developed and manufactured by JSC "Aquamarine") and self-propelled multipurpose device MG-74M (instead of the long-obsolete GIP-1, MG-34 and MG-74).
Details on the Vist-2 drifting device were given in the documents of a number of state purchases (on the official portal), but the key is the following:
- "Vist" - means of PTZ and does not have any effect on the operation of means of targeting weapons (in other words, through the telecontrol channel, the torpedo will confidently aim at our submarine according to the low-frequency SAC);
- against modern SSNs, the effectiveness of single drifting SGPDs is extremely low, and the group use of "Whists" is impossible, due to the outdated logic of their work. (In fact, there will be a "dog wedding" - those staged by the "Vista" group will work on the first emitting device and will "crush" themselves);
- short operating time of "Vista" does not allow diesel-electric submarines to move to a safe distance.
Let me emphasize that all these are facts that have long been well known to specialists. But to which our valiant Navy, as they say, "hammered a bolt." War is not expected, is it? Maybe not expected ...
The film shows the crew well, one can feel their love for their ship, and their attitude to the service with a soul. Take a look at these faces.
In the case of real hostilities, these are suicide bombers.
With minimal chances of causing any serious damage to the enemy. A good modernization of the submarine in the area of electronic weapons was carried out, but "they saved on matches" - GPBA. And the worst thing is just a catastrophic situation with our underwater weapons (both torpedoes and mines).
"Caliber"?
So these submariners were not given it either. Saved ...
The video shows the crew working out on the way out of the sunken submarine. The right thing ...
However, given the usual depths of the Sea of Japan, it is somewhat dubious. You can't ascend from a kilometer - unless at shallow depths "under the shore" ...
It is said about the fleet.
PS
As a postscript, I will quote from the article of 2019 in "NVO" "Varshavyanka" needs an upgrade ":
- the absence of a flexible extended towed antenna (GPBA) in the hydroacoustic complex (SAC);
- lack of ... anti-torpedo, low efficiency of the available passive anti-torpedo protection - hydroacoustic countermeasures (SGPD);
- in fact, the antique level of telecontrol of torpedo weapons, ... "frozen" at the level of Western models more than half a century ago.
Additionally,
It is impossible not to admit that today in the Pacific Fleet all these important decisions should not only be implemented as quickly as possible, but implemented in time. Especially considering that there is almost no time left ...
