Russian blogger “Atomic Cherry” argues that Ukrainian strikes on oil refineries will cause Moscow to perversely respond by forcing a reduction in consumption and the Russian economy itself.

A delegation from my volunteer group Defense Tech for Ukraine spent two weeks in Ukraine meeting with military units and defense manufacturers.
My strongest impression was of Ukrainian civilians completely ignoring the frequent air raid sirens and calmly going about their day.
1/ Even a Shahed attack on Kharkiv one night had no apparent effect other than an earlier blackout.
The Milky Way was vivid in the middle of the city!
The Ukrainian people seem determined to ignore the hated Russians as much as possible, and refuse to let them affect their lives.

Two Russian bloggers have opposing views on the effectiveness of steel mesh at protecting energy infrastructure from Ukrainian long-range strike UAVs.
“Two Majors” is scornful of these, arguing that the blast wave of a 50 kg warhead is hardly mitigated at a 2 meter stand-off.
1/ “We get a blast wave pressure of 9089 kPa.

That is, at the moment of the explosion, at 2 meters from the top of the tank, the pressure of the blast wave (excluding damaging elements) on one square meter of the protected object will be 9,089,000 N/m².

Ukrainian Serhii “Flash” Beskrestnov explains the origin and purpose of the mystery UAVs over Europe.

“✈️ Appearance
UAVs do not appear out of nowhere. They either fly in from afar through the air, and this route is clearly recorded by NATO air defense.
1/ Image “Or they are launched locally in countries by some ‘DRG’. [sabotage-reconnassaince group]
There is no information about all this. Although NATO has it. My personal opinion is that the launch was from the decks of Russian naval vessels in the Baltic Sea area.

As Russia increases its production of Shahed (Geran-2) kamikaze UAVs that led to the recent 800 drone raid, Ukrainian interceptor drones are urgently needed.
Missile systems are too expensive, so a cost-effective, very fast, and rapidly produced solution is required.
1/ Image Standard quadcopters are too slow and lack altitude reach to intercept a Shahed.
They were designed for hovering and flights at low level.
The key design change for interceptors is a fixed wing or hybrid frame that trades hovering for high speed and climb rate.

Batteries are the unsung heroes of FPV drones in Ukraine.
Motors and fiber optic control may get more attention, but it’s the chemistry inside lithium packs that sets limits on speed, payload, range, and battlefield effectiveness.
1/ Image FPVs in Ukraine use lithium-polymer (LiPo) batteries.
They’re lightweight, store a lot of energy for their size, and can discharge at very high rates.
That high “C rating” matters, because driving motors at full throttle demands extreme current in an instant.

The Russians claim that Ukraine has begun to implement mesh networks for FPVs.
New compact, inexpensive modems allow a swarm of drones to combine into a local network.
Each FPV can transmit and receive digital data packets.
1/ Image The operator when connected to one drone can control any other in the network.
The connection to the final FPV can be transmitted not through a single channel but simultaneously by several nearby drones.
This significantly increases resistance to EW jamming.
