1/ Tens of gigabytes of secret data on Russia's strategic electronic warfare systems has been hacked by the pro-Ukrainian Russian Volunteer Corps (RDK). They say that Russia's EW shield is "not just fragile - it's full of holes" due to multiple flaws and vulnerabilities. ⬇️ Image
2/ Two weeks ago, the RDK announced that it had obtained a large quantity of data on Russia's EW systems, including technical specifications, diagrams, official correspondence, equipment setup methods, drawings, test reports, and functional information.
3/ RDK commander 'Fortuna' says that "We got more than just the external appearance. We see the internal logic, architecture, connections between nodes, we know who designed it, which companies supplied the units, which research institutes are responsible for the developments."
4/ "We received a number of important military developments along with protocols, engineering solutions and approvals from the Russian Ministry of Defence. In addition, we managed to establish the entire chain of enterprises involved in production and supply.
5/ "And it is also important that all the persons involved in the development and creation of these stations were identified. Upon completion of the operation, the RDK had their names, addresses, car numbers, places of work."
6/ RDK announced in a YouTube video that it had obtained data on the following:

🔺 "ANCHAR-K — a polar warfare naval station. An automated station for electronic suppression of satellite communication lines in Arctic conditions. It is installed on icebreaker-class ships. Image
7/ "Developed as a response to the vulnerability of the Russian Federation in high-latitude areas."
8/ The system is intended to disrupt signals from satellites, aviation radars and ship navigation. However, the documents obtained by the RDK indicate that it is not capable of resisting Arctic conditions, including wind, cold and icing.
9/ According to the RDK, "When the ship maneuvers, the Anchar loses tracking. The guidance time is more than four minutes. In the event of a failure, the entire system is switched off." Its location is exposed when it is in operation.
10/ 🔺 "OZON-MEI — over-the-horizon. Over-the-horizon radar project using the evaporation waveguide effect. It works by forming a plasma channel in the near-surface atmosphere."
11/🔺 "Tirada-2.3 — "Interference". Satellite communications electronic suppression station. Part of the Tirada-2S complex."

According to the RDK, this is a narrow-target system for disabling satellite communications which uses directional antennas to focus on specific targets. Image
12/ Operating in ranges from 225 MHz to 15 GHz, it is used to temporarily disrupt communications with US and British military satellites (WGS, MUOS, Skynet).
13/ 'Fortuna' says: "Such a complex jams communications and also generates false signals. For example, a drone flying over the Bryansk region may "think" that it is over Ethiopia. Disorientation and substitution of coordinates occur."
14/🔺 "NMS REP DDV — suppression radio brain. Ground-based mobile station for suppressing long-range satellite communications. Controls other electronic warfare systems. Suppresses FleetSatcom, Milstar, MUOS, etc. links."
15/ The RDK desribes this as a key element of Russian signal suppression technology:

“This is a radio brain, everything depends on it: it determines radiation modes, types of interference, phasing."
16/ However, they say that it has serious flaws. It is reported to be extremely sensitive to weather, vibrations, requires complex settings and a stable power supply. The system copes poorly with combat conditions.
17/🔺 "Software modules, OS, CORVETTE. Operating systems and software modules used for protection and work with electronic warfare. We understand the architecture, but will not disclose all the security details."
18/ The hacked documents also reveal that Russia exploits China's satellites, apparently without China's knowledge. "Russia uses civilian Chinese satellites to cover the calibration of its systems."
19/ "That is, Russian electronic warfare systems are posing as terminals of the PRC’s civilian fleet in the Pacific Ocean. China has not been officially notified of this. If a signal is detected, Russia is betting that the responsibility will fall on the Chinese channel.
20/ "This is a risky game. Sooner or later, China will understand this. And we already know which satellites they “hang on to,” which channels they mimic. This is an extremely interesting and unexpected observation."
21/ 'Fortuna' says that Russian strategic electronic warfare systems suffer from the lack of an operational ecosystem. "This is a huge, overloaded structure, not ready for a real war."
22/ Russia has invested heavily in its EW systems to compensate for its relative lack of satellites, compared to the United States or China. The leak is likely to be a considerable setback, as it will enable Ukraine's Western partners to develop countermeasures. /end

1/ Russia is reportedly considering proposing a wide-ranging economic partnership with the Trump administration, including joint cooperation to push fossil fuels as an alternative to Chinese and European clean energy solutions, in opposition to curbing climate change. ⬇️ Image
2/ Bloomberg is reporting that Russia has prepared a seven-point memo that includes a return to the dollar settlement system, reversing Putin's by now well-established policy of creating an alternative system insulated from US economic pressure.
3/ The proposals also include joint US-Russian ventures in manufacturing, nuclear energy, oil and LNG extraction, preferential conditions for US companies in Russia to compensate for past losses, cooperation on raw materials, and jointly working against clean energy.

1/ Why does the Russian government appear to be so clueless about the role Telegram plays in military communications? The answer, one warblogger suggests, is that the military leadership doesn't want to admit its failure to provide its own reliable communications solutions. ⬇️ Image
2/ Recent claims by high-ranking officials that Telegram isn't relevant to military communications have prompted howls of outrage and detailed rebuttals from Russian warbloggers, but have also pointed to a deeper problem about what reliance on Telegram (and Starlink) represents.
3/ In both cases, the Russian military has failed abysmally to provide workable solutions. Telegram and Starlink were both adopted so widely because the 'official' alternatives (military messngers and the Yamal satellite constellation) are slow, unreliable and lack key features.

1/ Telegram is deeply embedded into Russian military units' internal communications, providing functionality that MAX, the Russian government's authorised app, doesn't have. A commentary highlights the vast gap that is being opened up by the government's blocking of Telegram. ⬇️ Image
2/ The Two Majors Charitable Foundation writes that without Telegram, information exchange, skills transfer, and moral mobilisation work within the Russian army will be crippled:
3/ "I'd really like to add that for a long time, we've been gathering specialized groups in closed chats, including those focused on engineering and UAVs, to share experiences and build a knowledge base. Almost everyone there is a frontline engineer.

1/ Russia's Federal Customs Service is seeking to prosecute Russian volunteers who are importing reconnaissance drones from China to give to frontline troops. It's the latest chapter in a saga of bureaucratic obstruction that is blocking vital supplies to the Russian army. ⬇️ Image
2/ Much of the army's equipment, and many of its drones, are purchased with private money by volunteer supporters or the soldiers themselves. High-tech equipment such as drones and communications equipment is purchased in China or Central Asia and imported into Russia. Image
3/ However, the Federal Customs Service has been a major blocker. Increased customs checks on the borders have meant that cargo trucks have suffered delays of days or even weeks, drastically slowing the provision of essential supplies for the Russian army.

1/ Leaked casualty figures from an elite Russian special forces brigade indicate that it has suffered huge losses in Ukraine, equivalent to more than half of its entire roster of personnel. Scores of men are listed as being 'unaccounted for', in other words having deserted. ⬇️ Image
2/ The 10th Separate Guards Special Purpose Brigade (military unit 51532) is a special forces (spetsnaz) unit under the GRU. It is a 2002 refoundation by Russia of a Soviet-era spetsnaz unit that, ironically, passed to Ukraine when the Soviet Union broke up in 1991.
3/ Since the invasion of February 2022, the brigade has been fighting on the Kherson front, which has seen constant and extremely bloody fighting over the islands in the Dnipro river and delta. Russian sources have reported very high casualties.

1/ Russian warbloggers are continuing to provide examples of how Telegram is used for frontline battlefield communications, to refute the claim of presidential spokesman Dmitri Peskov that such a thing is "not possible to imagine". ⬇️ Image
2/ Platon Mamadov provides two detailed examples:

"Example number one:

Aerial reconnaissance of Unit N spotted a Ukrainian self-propelled gun in a shelter in the middle of town N."
3/ "Five minutes after the discovery, the target's coordinates and a detailed video were uploaded to a special secret chat group read by all drone operators, scouts, and artillerymen in that sector of the front.
