Prominent Russian blogger “Veteran’s Notes” laments the “humiliating” failure of the State to provide heavy lift drones like the Ukrainian “Vampire.”
Instead, Russian frontline units must be supplied by human bearers and a handful of salvaged Ukrainian drones.
1/ Image “Recently, our unit lost a trophy drone, which I mentioned earlier.

It served the Russian army faithfully for exactly one month.

The Russians recovered an 8-element GPS-jamming-resistant CRPA satellite navigation system that is apparently from an AGM-188A “Rusty Dagger” cruise missile.
This is a 930-km range, low-cost missile to be carried by F-16s and intended primarily for use by Ukraine.
1/ Image
Image Initial deliveries are scheduled for October, but the recovered device may indicate that a test batch has already been sent to Ukraine.
The Russians claim that the CRPA was made by Zone 5 Technologies, the developer and manufacturer of the missile.

Excerpts from an interview with Andriy Biletsky, commander of the Ukrainian 3rd Army Corps.
He believes a turning point in the war is approaching.
1/ Image “It's obvious that Russia had a rather unsuccessful winter campaign, and they completely failed their spring campaign. In fact, in May, they managed to capture about 10 square kilometers of territory.

Since its disconnection from Starlink, Russia is urgently pushing forward its own LEO high-speed satellite constellation called “Rassvet”.
Ukrainian communications expert Serhii “Flash” Beskrestnov analyses its status and prospects.
1/ Image “1. The enemy needs a ‘Russian StarLink’. Undoubtedly, Russia understands the importance of a high-speed data transmission system via low-orbit satellites, and it would be foolish to think they wouldn't pursue this direction. The question is just about timing.

Russian sources report that Ukraine has started dropping anti-vehicle landmines on the M-14 highway between Melitopol and Mariupol.
This key logistical route to Crimea is 100–150 km from the front lines and would require fixed-wing UAVs to reach that far.​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​
1/Image This highway has been the primary focus of Ukraine’s sharp rise in strikes on Russian trucks using mid-range UAVs like the “Hornet.”
Landmines at operational depth on this and other routes will greatly increase pressure on Russian logistics.

Serhii “Flash” clarifies new Russian tactics that combine “Geran-2” attacks on Ukrainian air defense units while another UAV simultaneously strikes the main target.
First, a “Gerbera” reconnaissance UAV studies the air defenses to determine their movements and locations.
1/ Then, a double strike is applied—one Geran-2 strikes and distracts the ground-based air defenses, while another attacks the target.
“Flash” advises using camouflage, changing to backup positions, and closely monitoring reconnaissance UAV flights.

Russian blogger “Philologist in Ambush” (Svyatoslav Golikov) warns Ukraine is no longer just flooding the front with drones.
It is building an adaptive, networked strike system that is increasingly outpacing Russian EW and logistics defenses.

The Russians have developed a new radio reconnaissance system called the “Meshtastic-Sniffer” for detecting and analyzing Ukrainian Meshtastic/LoRa mesh networks.
Using multiple synchronized receivers, it can geolocate transmitting nodes via TDOA (Time Difference of Arrival).
1/ Image It is important to note that mesh networks and Meshtastic are different.
A mesh network is a general communications architecture in which devices relay data to one another without a central base station.
Meshtastic is one specific implementation that uses LoRa radio modules.

The sorry state of Russian surface warship construction is exemplified by the long-delayed commissioning of the small 800-ton missile ship Burya.
Laid down in December 2016 and launched in October 2018, it then sat idle for years awaiting its diesel engines.
1/ Image Even then, sea trials dragged on for another three-and-a-half years due to chronic engine problems.
Originally, German high-speed diesel engines had been intended, but sanctions imposed after the 2014 annexation of Crimea cut off supplies.

Ukrainian EW and radio expert Serhii “Flash” Beskrestnov was an early supporter of the importance of UGVs.
Here are excerpts from an interesting interview with him by ArmyInform.com.ua

Russian blogger “Kuban” describes the tactics for evading an incoming FPV.
The essence: a moment's hesitation is death.

“FPV ABOVE THE HEAD: SECONDS MAKE THE DIFFERENCE.

The Russians have failed to develop an equivalent of Ukraine’s successful Sky Fortress acoustic system that detects and tracks Shahed UAVs
Russian bloggers are angry that a recent 1,800 km Ukrainian UAV strike past the Ural Mountains went undetected by Russian air defenses.
1/ Image Sky Fortress is a system of microphones mounted on cellular towers connected to central processing nodes.
AI algorithms detect the distinctive sound of Geran-2 (Shahed) engines, enabling mobile ground fire teams to be dispatched and stationed ahead of the UAV's flight path.

Russian blogger “Military Manager” has described the tactics of Russian “Molniya” strike UAVs used to minimize the heavy losses occurring to Ukrainian interceptor FPVs.

“1. Your target is in a forest belt in the enemy's notional rear area. 10-15km from the front line.
1/ “Several villages behind the LBS [Line of Contact] are directly on the route. How will you fly? The answer is obvious. Of course, we will bypass all NP [settlements] and the forest strips that are part of it.

I just reread Adam Tooze's magisterial The Wages of Destruction: The Making and Breaking of the Nazi Economy, and the parallels with Russia's deteriorating wartime economy are striking.
By the late 1930s, Hitler's massive rearmament program consumed 20% of national income.
1/ The result was a civilian sector starved of labor, materials, and capital.
Consumer goods production was squeezed, infrastructure lagged, and bottlenecks spread across the country.
Despite headline armaments growth, overall productivity was undermined.

Russian milblogger “Two Majors” complains that Ukraine is trying to push Russia out of Africa.

“On April 14, 2026, as part of the Food from Ukraine initiative, the first agrohub (Food Processing and Distribution Center) was opened in 🇬🇭Ghana.
1/ Image “The population is being lured with free food – a mixture of flour and rice (4,000 kits were distributed at the opening), and the authorities with bribes.

Ukrainian “Vampire” heavy bomber drones are switching to Starlink communications, allowing operators to stay hundreds of kilometers from the deadly grey zone.
Previously, Vampires relied on radio and GPS for control and navigation—both highly vulnerable to jamming.
1/ Image GPS jamming or spoofing from Ukrainian electronic warfare (EW) systems, targeting incoming Russian “Geran-2” drones, can also down nearby Vampires.
Starlink provides immunity to EW, and its expanding use magnifies Russia’s loss of Starlink since its disconnection by Elon Musk.

The Russians are very concerned about the emergence of the Ukrainian “Hornet” strike UAV (Russian name: “Martian-2”) from Eric Schmidt's Swift Beat company.
It reportedly has autonomy and terrain-following capabilities that were previously seen on the Russian “V2U” strike UAV.
1/ Image Here, a Hornet UAV destroys a Russian “Zoo-1M” counter-battery radar.
The medium-range UAV can automatically detect, classify, and lock onto a target, as seen here by the on-screen tag “VEH/ARM” (armored vehicle).

Ukrainian blogger Maria Berlinska of “Victory Drones” had a revealing conversation with a taxi driver from Russia.

“Late evening, I’m running late for the metro, so I call a taxi.
The driver’s profile appears in the app — high rating, 17 thousand rides.
1/ Image “I get in, we go. The driver asks for the address again, in Russian. That very Russian that I wouldn’t confuse with anything else. Neither with Russified Kharkiv, nor with Dnipro or Donbas. Russian from Russia.

The accelerometer in the flight controller (FC) of an FPV drone measures linear acceleration, helping the FC understand the drone’s current direction and the force with which it is moving.
1/ Image The solid-state accelerometer has a tiny “proof mass”suspended by springs.
When the drone accelerates or tilts, inertia shifts the mass slightly.
This movement is measured electronically along the X, Y, and Z axes, telling the FC the FPV’s direction and which way is down.
