A Russian blogger explains that thermal cameras are now the primary sensor on the Ukrainian battlefield.

“Modern warfare has completely shifted from the visual plane to the thermal one.
1/ “The experience of the Special Military Operation (SMO) has shown in practice that the battlefield today is controlled not by a soldier's eyes, but by the matrix of a thermal imager installed on a drone, which can hover over an area for days…

The RAND corporation has published a study of whether directed energy weapons (DEW) can be useful in Ukraine.
The study concluded that neither high-energy lasers (HEL) nor high-powered microwave systems (HPM) in their current state of development are suitable for Ukraine.
1/ Image The technological readiness level (TRL) for HEL or HPM systems varies, but none are ready for mass production.
DEW weapons require enormous amounts of power, and lasers generate huge amounts of heat.
Atmospheric conditions can also significantly limit HEL effectiveness.

This Russian “Geran-2” (Shahed) has a new antenna, apparently for navigation using radio beacons.
Ground-based VHF omnidirectional azimuth radio beacons (VOF) broadcast a reference signal in the 108–118 MHz range, while encoding azimuth bearing in a rotating variable signal.
1/ Image The azimuth (radial angle) from the UAV to the station is determined by the phase difference between the reference signal and the narrowly directed variable signal.
This may be paired with DME (Distance Measuring Equipment) for a full position fix, independent of GPS.

Logistics to the Ukrainian frontlines is increasingly being supplied by UGVs and heavy multirotor drones.
In one assault brigade, up to 40 tons per week are sent this way, representing 80% of total logistics delivered.
1/ UGVs in particular are replacing traditional logistics involving infantry and vehicular transport, which can no longer survive in the 20 km grey zone of constant aerial surveillance and FPV strikes.
Drones are attritable and save Ukrainian lives by replacing men with machines.

Russian blogger “Reporter Filatov” does not believe claims by Russian heavy multicopter developers that their products are in frontline service, and are just part of corrupt arrangements with military personnel.

Further excerpts from the interview with the Commander of the Ukrainian Special Electronic Support Center, on how to improve tactical EW.

“Firstly, the means must be easy to modernize because frequencies and application algorithms constantly change on the front.
1/ Image “Moreover, the Russians can switch both to new frequencies and return to old ones. Accordingly, the means must also be changed quickly. Unfortunately, most systems are currently tailored to specific characteristics, and to change them, new ones must be purchased.

More Russian “Gerbera” reconnaissance UAVs are armed with OFBCh-2 fragmentation warheads.
The inertial impact UZ-2 fuze is also used on OFZBCh-50 “Geran-2” warheads.
The fuze is armed by the UAV's flight controller (FC) shortly before impact, likely prompted by altitude.

Image Just before the flight a mechanical safety that partly locks the primer mechanism from moving into alignment is released, but the fuze is not yet armed.

“Why you need to be careful when using a phone at the front line. Let's consider the issue using the example of the ELINT system (Electronic Intelligence).

The progression in capabilities of the Russian UMPK guided glide bomb series for FAB-500 aerial bombs

The original UMPK for the FAB-500 M62 aerial bomb was guided by a 4-element “Cometa M4” CRPA jam-resistant satellite navigation system, with up to 75 km in range.
1/ Image The first major upgrade is the extended-range UMPK-PD, with increasingly difficult to jam 8 and then 12 element “Cometa M8–12” satellite navigation.
Extended wings and a new FAB-500T bomb with better aerodynamic qualities increases the range to 100 km.

VictoryDrones's Maria Berlinska argues that victory for Ukraine will come by winning the race to an army of fully autonomous drones, and not with Tomahawks.

“I do not claim to have the ultimate truth; this is purely my broad vision of the next stages of the technological war.

Just to understand the overall picture and trends.

The first stage - drones are controlled by humans directly on the battlefield. Mainly for artillery fire correction and reconnaissance. The first attempts at strike operations - drops, kamikaze.
