A British RC-135 surveillance aircraft joined an American RC-135 and an Italian G550 in conducting patrols over almost the entire length of the NATO border with Russia.

The RC-135W Rivet Joint and its sensors are designed to undertake ā€˜signals intelligenceā€™ missions. In other words, they ā€˜soak upā€™ electronic emissions from communications, radars and other systems.

As we need to post this each time, hereā€™s the usual disclaimer. This isnā€™t a new occurrence. It is pretty routine. The UK has long been gathering intelligence about Russian forces since long before the invasion of Ukraine, and it should be noted that these flights are designed to be visible so that the public and Russia know theyā€™re happening. If it were a secret, I would not know. Also, for those remarking, ‘this isnā€™t new’, thatā€™s right, but people only know this often happens because it is reported often.

British surveillance aircraft being over the area isnā€™t unusual, but we are seeing a significant increase in the frequency of the flights over the last few months for obvious reasons.

What does the RC-135W do?

According to the Royal Air Force website, the RC-135W Rivet Joint is a dedicated electronic surveillance aircraft that can be employed in all theatres on strategic and tactical missions. Its sensors ā€˜soak upā€™ electronic emissions from communications, radar and other systems.

ā€œRC-135W Rivet Joint employs multidiscipline Weapons System Officer (WSO) and Weapons System Operator (WSOp) specialists whose mission is to survey elements of the electromagnetic spectrum in order to derive intelligence for commanders.ā€

The Royal Air Force say that Rivet Joint has been deployed extensively for Operation Shader and on other operational taskings. It had been formally named Airseeker, but is almost universally known in service as the RC-135W Rivet Joint.

The UK operates three of these aircraft.

  1. Not mentioned here but on Adsb you could also see a German aircraft in the baltic sea in front of Kaliningrad. The plane was of unknown type but departed from Nordholz which hints it might have been a P-3 Orion anti sub aircraft. The amount of surveillance around Kaliningrad is a bit suprising.

    • It is easier to overtly keep an eye on things rather than let something silly kick off and then try and contain that?

        • I didnā€™t suggest it wasnā€™t.

          An ASW plane would suggest that NATO was signalling that it knew a sub was being prepared for a mission.

          That can be as simple as the thermal signature from cranking the reactor or diesels up, or even ELINT or even someone with binoculars watching storing of perishables!

          • The Baltic Fleet isnā€™t really much of a threat when it comes to submarines. There are no nuclear ones and just 1 older Kilo class. It can be reinforced via the Internal waterways but Kilos are pretty well the limit of that route. Itā€™s just too confined and small for modern Submarine operations unless you are using small stealthy AIP that are specially designed for it. Russia doesnā€™t have anything like the German or Swedish boats. Even a Kilo is big in the Baltic.
            MPA do not just do ASW, Iā€™d suspect what they are keeping an eye on are Russias Iskander Missiles at Cape Taran and the Missile Corvettes that may have Tsirkons fitted,

          • Ok I was clearly wrong about nuclear subs there. For some odd reason I thought they did at one time.

            In their prime the Kiloā€™s were much feared.

            I agree the Russian conventional subs donā€™t exactly have NATO grade anything these days!

          • Believe any increased tempo of surveillance sorties is directly correlated w/ tempo of Russian activity in UKR, especially the Donbas. Is the pace sustainable over an extended timeframe?

  2. Time to get as much kit across the borders as possible.

    Russian offensive has ‘definitely’ started, Ukrainian official says

    “A major Russian offensive that Ukraine predicted the Kremlin would launch before the first anniversary of the war has started, Ukrainian officials have said.
    Asked on Ukrainian television if he agreed that the offensive had already begun, Pavlo Krylenko, governor of the eastern Donetsk region, said: “Yes, definitely.”

    Around eastern towns such as Bakhmut, Avdiivka and Vuhledar that have witnessed some of the bloodiest battles of the war, “the enemy’s forces and means are escalating there with daily intensity”, Mr Krylenko added. 
    Luhansk governor Serhiy Haidai told Ukrainian Radio NV: “Over the past week to 10 days, the frequency of shelling has increased. The daily number of attacks has increased.

    “In real terms, this is part of the full-scale offensive planned by the Russians.”
    He also said there was a major new Russian assault around Kreminna, along a northern stretch of the eastern front, but that Moscow’s forces were “having no significant success”.
     
    Sky News has not been able to independently verify the reports.
    The Russian offensive comes at the end of a week in which Volodymyr Zelenskyy has travelled around European cities making pleas for Western allies to send fighter jets to Ukraine.

    The Ukrainian president said yesterday that several European leaders were ready to supply aircraft.

    Mr Zelenskyy has said the provision of jets would be one of the biggest shifts yet in Western support, while Moscow has warned it would escalate and prolong the conflict.

    Emmanuel Macron, the French president, said he had not ruled out sending fighter jets to Ukraine at some point.

    But Mr Macron has said the priority is to help Ukraine in the weeks and months ahead, and fighter jets could not be delivered in that timeframe and it would take time to train Ukrainian pilots to fly them.

    The French leader said the priority should be on military aid such as artillery, which had proven to be effective and on which Ukrainian forces were already trained.
     
    He said it might be necessary to intensify the delivery of such items and Ukraine’s allies would examine this possibility in the coming days.”

    • French Defence Minister SĆ©bastien Lecornu and his Ukrainian counterpart Oleksiy Reznikov signed a contract with Thales for the delivery of a short-range air-defence system.

      Under the contract, Thales will supply its Ground Master 200 (GM200) radar as well as a command-and-control (C2) centre, a radio communications system, and air target designators to Ukraine, the company announced on 1 February.”

  3. I once found myself in an RAF recruiting centre enquiring about Air Electronics Operators. Had my eyesight been better I might have ended up on Nimrod R1’s, what an experience that would have been!

    • I donā€™t think they had computer generated names in the early 60ā€™s. Rivet Amber, Brass etc etc.
      It would be generated just like we did used Blue, Green, and another word to make a name or code word.
      Blue Danube, Red Beard,Blue Steel, Yellow Sun etc.

      • Apparently, so I read once, our random names for ops get generated by a computer within PINDAR. True or not, no idea.

        • Military Ops and designations now there is a subject you could write a book on.
          Iā€™m not sure they are computer generated when you look at some of our Ops codes Corporate, Granby, Telic etc.

          The US really donā€™t do subterfuge or subtle. Dessert Storm, Shield, Deny Flight and Provide Comfort etc.

          Conversely they donā€™t use plain, simple English for important things.

          US ā€œIncomingā€ = Hit the dirt, British ā€œDuckā€ = ā€¦..

          US ā€œFreindly Fireā€ = Oops sorry we thought you were the enemy, even though you are right next to us and facing in the direction of the enemy.
          British ā€œFriendly Fireā€ = Dry your socks out and weā€™re Brewing Up.

          As for Acronyms Iā€™d love to know who pointed out why the U.K, NZ and Aussies all laughed when they saw : –
          The War Against Terror as an Acronym.

          U.K. equipment and project codes go way back to post war MOS days. The Rainbow codes were 2 random words consisting of a Random Colour and a Random Noun. I have no idea how it was generated (but it wouldnā€™t be a computer).
          Being British it was probably stick a colour on a Dart Board and then flick open a page in a book of nouns then check if anyone else has used it.
          The idea was to give it a designation which we used but gave no idea to the enemy as to what it was.
          Examples :-
          Blue Sreak was a MRBM
          Blue Danube 1st deployable U.K. A Bomb
          Blue Fox Sea Harrier Radar (odd one cause it was replaced by Blue Vixen)
          Blue Steel (you know that one).

          As for the Yanks their lettering is supposedly simpler W stands for Weather Reconnaissance and the C is because it comes after A, B etc
          WC-135 is to cunningly throw the enemy off track. As it is sampling for nuclear tests.

          IMHO if it was in RAF service
          I would use an acronym (very modern). SARLF

          If you detect nuclear fallout.

          Sniff And Run Like Fā€¦k

          You get my drift (there is a pun in there).

        • Weā€™ll sort of the airframe is a modified KC-135 Stratotanker which was in turn a tanker version of the C-135 Stratolifter first flown in 1956.
          The RC-135 was ordered in 1962 as a modification and designated RC-135A as it was based on the KC-135A
          They have been updated, rebuilt, re engined etc etc.
          Our 3 were converted from the newest examples in the USAF fleet
          They were built in 1964 and should go through to 2045.
