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/ The Russian-occupied city of Donetsk in eastern Ukraine is under a 'drone siege', according to local inhabitants. Ukrainian drones are striking targets across the city and the surrounding region. A resident provides a vivid eyewitness account. ⬇️
2/ 'Donetsk MartynoVa', a pro-Russian resident of Donetsk who positions herself as an influencer and Telegram blogger, has been writing about the deteriorating situation over the past month. On 11 May, she wrote:
3/ "The news brings information that drones are already harassing the land corridor, but, judging by the number of cars from Crimea, this doesn't stop many [travellers]."

By 18 May, the drone campaign had been stepped up:

1/ Russia's captured and corrupted bureaucracy, which is under the thumb of powerful industrial concerns and complicit politicians, is strangling independent developers of military electronics. Several developers are complaining about the situation. ⬇️ Image
2/ Gagaring Lab, a developer of drone detectors and other military electronics, highlights how the 'People's Military-Industrial Complex' is being throttled:

"China launched a new strategy in February. China wants to be not only the world's factory, but also its laboratory."
3/ "Programmes have been launched to attract R&D companies to China. In Russian: welcome, developers, we will create the conditions for you. And here, people are worried about developers running away, but not about entire companies running away.

Strange.

1/ News that Russia's BMPT Terminator, famed for its wobbly autocannons, is to be renamed the Spirodon has attracted criticism from Russian warbloggers. Perhaps not coincidentally, Spirodon also was the first name of Vladimir Putin's paternal grandfather. ⬇️ Image
2/ According to Uralvagonzavod's official channel, "The machine, which replaces an entire unit, no longer bears the nickname of the American destroyer robot. It is our shield and sword."
3/ The official announcement says that the change in name was made "at the request of Uralvagonzavod workers (part of Rostec) and combat vehicle crews ... in honour of courage, resilience, and strength of spirit."

"Why "Spiridon"? This is a rare but revered name in Russia."

1/ Russia may be forced back to its 1991 borders as the Ukraine war turns against it, a Russian warblogger warns in a gloomy commentary. The prospects of a ceasefire on the current line of contact are slipping away and the threat to Russia itself is increasing. ⬇️ Image
2/ 'Tulenkov', a Russian former soldier who fought in Ukraine, writes:

"As far as I can tell from my understanding of the situation on the battlefields of the Special Military Operaion, we've already lost sight of the option of freezing the line of contact."
3/ "Currently, it's of no interest to the enemy and its masters.

Until they fully exploit the capabilities of Palantir and other Karpov-like ideas, no one will put the war on hold.

Therefore, the next stage of real negotiations will be the 1991 borders.

1/ Russian soldiers in Ukraine are unhappy that army health and safety inspectors have ordered them to tear down their camouflage nets because they are too flammable. They've been told to put up bright red fire safety equipment instead. ⬇️ Image
2/ 'Unofficial Bezsonov' complains:

"A commission from Moscow visited some of our units' temporary deployment locations. They ordered us to remove camouflage nets, as they violate fire safety regulations, and to hang up red signs like these."
3/ "Friends, these are frontline zones where our soldiers are trying to deploy secretly.

The war is five years old, but the number of differently-talented people serving on these commissions hasn't decreased.

1/ A fuel shortage is expanding across Russian-occupied areas of Ukraine due to Ukraine's drone strikes. The Russian warblogger 'Two Majors' reports that it is degrading Russian combat capabilities across the Donbas front lines, as well as in the south. ⬇️
2/ On Telegram, 'Two Majors' writes:

"The problem is broader than just the land corridor to Crimea.

The destruction of our logistics to an operational depth of up to 200 km creates problems not only with the fuel supply to Crimea, as esteemed Comrade Rybar writes."
3/ "The operations of Ukrainian drones over the roads of the long-suffering Donbas are no less serious, although less publicised. This is understandable, as people don't go to Donetsk for summer vacations.
