A few months later than normal, but here’s a copy of my article from the June edition of The Spectrum Monitor
Russian Navy around the World
The Russian Navy has started to get active again after the usual period of rest over the winter months. The main reason for this is because most of the areas the Navy operate from in the North are frozen over, and are only just now starting to thaw out. There are three busy areas that produce the most traffic in the summer, but one of those practically disappears over the winter; and that is the area that falls under the command of the Northern Fleet, and in particular the White Sea. I intend to cover the Northern Fleet in much greater soon.
One thing that is noticeable is that the fleets seem to have moved to a more regional network of frequencies. They used them anyway before, but in general they tended to stick to 8345 kHz at night and 12464 kHz during the day as the main ship frequencies. I suspect that with the large increase of ships becoming active these frequencies were getting saturated with calls – something that was becoming noticeable as ships were “stepping” on each other. I mentioned last time that these main frequencies were quiet, and it now looks like this it was the reason.
As I say, I’ll go into regional stuff through the rest of the year so I’ll concentrate on a couple of interesting things that have happened over the last few months.
One of my favourite ships is Admiral Vladimirskiy, a Akademik Krylov Class Survey/Research Ship that uses the CW callsign RHO62. From late August 2014 this ship carried out a round the world trip, starting from the Baltic Sea headquarters at Kronshtadt, routing around the north coast of Russia through the Barents Sea, Kara Sea, Laptev Sea, East Siberian Sea and through the Bering Straits. From there it head south down to Taiwan and then across the Pacific to Corinto in Nicaragua, down through the Panama Canal, across the Atlantic to Brest, through the English Channel and home to Kronshtadt. It returned home on the 18th of January 2015 – a huge trip and one that our small group of monitors was able to track the whole way round, probably getting around 95% of all weather/TESAC reports that it sent. After that, it needed a good rest, and that it had until November last year when it set sail for the Antarctic.
Again, we have been able to follow its travels all the way down to the Northern edge of the Antarctic Ice belt, where it operated for some time near Davis Station, part of the Australian Antarctic program. They have a great website which provides various webcams, but unfortunately Vlad didn’t get within their sights. It’s worth checking out their website, just so that you can watch the fascinating time-lapse videos that are produced from the webcams. Vlads route took it this time through the Med, through the Suez Canal, the Gulf of Aden, along the East coast of Africa, stopping off at Madagascar for Christmas. Then it was down to Port Elizabeth in South Africa, before its final push to the Antarctic, getting there mid-January. For its time down to around Madagascar it stuck to 8345 or 12464 for its reports, but later on it transferred to 8460 kHz where it then spent most of its time. It would try the other frequencies should it not get through of course, there’s a huge selection that it could choose from.
8460 kHz is noted as being used by RMP (Baltic Fleet HQ at Kaliningrad) but in fact Vlad was calling RJH25 to pass on its messages. RJH25 is a RX/TX site in Kyrgyzstan and in this case is used in simplex instead of the normal duplex. This was good because it meant we were able to get both sides of the conversation easier than having to monitor lots of frequencies in duplex mode. A link to Google maps is in my callsign list which shows the RJH25 antenna site.
Here is one of my receptions of a FM-13 weather report from the 15th February on 8345 kHz:
0010z RHO62 586 20 15 0301 586 = SML FOR RJH45 RJH48 RJH74 RJD38 =
15001 99655 30900 22233
I’ve missed out most of the weather information to show the relevant data for positioning. The data equates to RHO62 being at 65.5S 90.0E heading SE @ 11-15kts. This is approximately 9670 miles from ship to my Wellbrook Loop antenna!! I must say, I am very pleased with that achievement.
So, what are the Hydrographic ships of the Russian Navy doing? Their main task is to carry out data acquisition of the waters that the Russian navy operate in, which is why the TESAC is very important to them. The checking of sea temperatures against salinity levels helps them in various ways, but there are two particular reasons for this data. One, is that temperature and salinity actually affect how torpedoes and missiles from underwater launches travel through the water – the higher the salinity and colder the sea water is, the more it can cause drag. The second is for much the same reason, but in this case it is for Submarines. Not so important for the Nuclear powered ones, but a little more so for the SSK’s as this can affect the time they can stay underwater before requiring to surface to “snort” and power up their batteries.
The TESAC data also provides the depth of the sea though most of the Hydrographic ships will have equipment that fully maps the sea beds. Again, depths are important, especially for the Submarine fleets, and I suspect they use these ships to map potential routes to strike areas for the SSBN’s. You see a good amount of Hydrographic ship activity in the Northern waters of the Arctic for instance, as with the higher sea temperatures, and the receding Ice cap, more routes are becoming available there – and this is useful for the ships too.
And finally, of course, the Hydrographic ships will be providing information to the Russian Government, not only on things like climate change but also in the search for oil and minerals. The Russians have a civilian Hydrographic fleet for this, but it is not large and so they will use data acquired from the navy too.
The navy fleet consists of around 80 ships that are potentially capable of providing Hydrographic readings, though it is hard to find out exactly whether each one can or cannot. There’s certainly quite a few in the Baltic, where they test the SSK’s and torpedoes. And there’s also plenty in the Northern fleet which has a huge areas in the Barents Sea and White Sea for the testing of missiles launched from SSBN’s. They will use the Hydrographic ships to analyse the water before and after any trials of the submarines or weapons.
Monitoring 8460 Khz for RHO62 also brought us some luck with another callsign, RMGZ, a Prut Class Submarine Rescue Ship named Epron. This had in late summer 2015 travelled east from its home at Sevastopol in the Black Sea, again via the Med and Suez Canal where it was eventually lost from our radios off the east coast of Sri Lanka. It had been erratic on 8345 up until then anyway, and this was probably because it looks like it was using 8460 as its primary frequency. Of course, we didn’t know this as we weren’t monitoring it. Epron was heading towards Visakhapatnam in India to take part in exercises and later on in a Navy exhibition. My furthest east report from it was at 16.3N 82.5E, about 50km SW of Visakhapatnam. Epron is now at home in Sevastopol after its long journey.
I mentioned last time Project 550 Large Dry Cargo and Passenger ship Yauza which uses the callsign RHM80. Yauza has been a very busy ship over the last few months as part of the Russian ferrying of equipment and troops to Syria – named by many as the “Syrian Express”.
In all, our tracking of RHM80 shows it made five trips to Tartus from either Sevastopol or Novorossiysk , both being Russian Navy bases in the Black Sea. The last trip to Tartus has ended, and instead of heading round towards the Bosporus, it headed towards Malta, arriving there on the 4th of April; it will probably travel onwards to its Northern Fleet base of Murmansk after picking up some supplies for the journey from Valletta. The Russian navy quite often uses Valletta as a stop off point and with plenty of ship photographers there, it is a useful port for tying up callsigns to ships.
Of course we will be tracking it all the way home on 8345 and 12464 as it is very good at sending FM-13’s every six hours as required. It also sends lots of “11111” messages – so called because of the first five figure group in messages to Moscow (RIW), Sevastopol (RCV) and Severomorsk (RIT). These are status messages I believe and of low priority, and are very common. But, you don’t need to be listening out on the Russian frequencies to track Yauza, you can just use MarineTraffic to track it. Just enter its name into the search area.
Yauza wasn’t the only ship involved in the “Syrian Express” so there was plenty of traffic from other ships. Some of the callsigns we know and some of them we don’t. There’s still a couple of Large Landing Ships that are avoiding us, but it looks like I have been able to tie-up at least one ship that is currently involved in Syria – and this is RKA80. This I believe is Slava Class Missile Cruiser Varyag, and it’s given itself away by sending messages via RCV for RJS, the callsign for Pacific Fleet HQ, Vladivostok. The messages started around the time that Varyag arrived in the Mediterranean Sea so time will tell if it disappears from the frequencies once it departs the operational area. It has recently stopped sending messages with the extra section for RJS so I wonder if it’s realised it was giving itself away? An example of their messages is here:
1900z RKA80 639 106 29 1230 639 = SML FOR RJS =
MMMMM ХАФЖШ ШЫЖКТ ….. ЦЦЬДЦ ВОПЫУ
АБПУИ = + RKA80
I removed most of the message for ease as this one was 106 groups long, but this was part of what looks like a standard schedule of three priority messages, each well into the hundreds of groups (normally around the 150 mark)
Well, I hope I haven’t gone on too much. Not much frequency information for you this time but I that I plan to change when I start with the Fleet information articles in the future. 8460 kHz monitoring has also bought us some other interesting things which wasn’t known before – but that would fill one article on its own.
As I say, keep an ear out on 8345 Khz and 12464 kHz. And if you’re on the West Coast of North America then try 8348 kHz which seems to be the Pacific Fleet primary CW frequency. If you do decide to give it a try then if you do manage to get anything, in particular from North America, then please do contact me either using my contact info in my blog, or via the TSM editor. I’m very keen to see what coverage there is elsewhere in the world.
Since the time that I wrote the article I have confirmed that RKA80 is Varyag
