As Ukraine introduces high speed drone interceptors to defeat Russian “Shahed-136” (Rus: Geran-2) kamikaze UAVs, it should be anticipated that the Russians will react with countermeasures.
The battle between Russian reconnaissance UAVs and Ukrainian FPVs provides a template.
1/ Image
Special Ukrainian FPVs began intercepting and destroying large numbers of reconnaissance drones such as “Zala” and “Supercam”.
The Russians first responded with an EW system that detected the video signal of the FPV, and initiated strong jamming in that frequency.
2/
This system apparently had some success, but was replaced by a rear-facing camera and an automated evasion program, possibly with some machine learning.
Upon sighting an approaching FPV, the Russian UAV automatically turns and dives, significantly complicating final attacks.
3/ Image
The rear cameras with evasion would most likely be the first countermeasure mounted on Shaheds if the Ukrainian interceptors continue their successes.
The recently seen Shahed with AI autonomy and terrain following is likely much too expensive to be made in large numbers.
4/
Shaheds use satellite navigation, and the struggle between increased Ukrainian EW jamming and more jam-resistant Russian CRPA antenna systems will continue.
The first 4-element “Cometa” has been replaced with 8, 12, and now 16 element CRPAs produced by Russia, China, and Iran.

Controlled Reception Pattern Antennas resist jamming by adjusting reception.
Using multiple elements directions of minimal sensitivity are steered towards a jammer, while maintaining gain for GPS signals.
Adaptive beamforming counters multiple jammers, giving stable reception.

Russian politician and blogger Dmitry Rogozin continues his examination of “Madyar's” adoption of corporate practices and metrics instead of traditional military bureaucracy to achieve battlefield truth.

“In parallel, a large-scale management reform is being carried out.
1/ Image
“Project management is being introduced, personal responsibility is being strengthened, transparent calculation of needs is being automated, redundant positions are being cut, and the role of analytics is being enhanced.
2/
“In essence, the Ukrainian leadership is striving to replace the traditional military bureaucracy with a corporate management model.

FPV drones have risen from an obscure hobby of racing drones to the mass production of millions and dominance of the Ukrainian battlefield.
However, cheap but lethal FPVs are rapidly being assimilated by terrorist and separatist organizations, cartels, and criminal gangs.
1/ Image
In the Sahel, al-Qaeda-linked Jama’at Nusrat al-Islam wal-Muslimin (JNIM) has used FPV drones armed with explosive warheads against fortified positions.
This marks a significant shift from indirect IED warfare to long-range precision-guided strikes.
2/ Image
Other regional jihadist actors, including elements tied to Al-Qaeda in the Islamic Maghreb (AQIM), Islamic State West Africa Province (ISWAP), and Boko Haram, have adopted similar FPV systems.
Commercial quadcopters have been adapted into guided kamikaze attack platforms.

Russian blogger Dmitry Rogozin compares Ukraine's Unmanned Systems Forces Commander “Madyar’s” use of statistics-based management, transparency of data, and confirmed results of operations with the Russian inheritance from the Soviets of the “operational lie”:
1/ Image
“In early 2026, one of the key commanders of the Ukrainian drone units, … Brody-Madyar, published a programmatic text in which he detailed his vision of the development of the war against Russia for the next year.
2/
“This material is noteworthy not for its grandiose slogans or emotional rhetoric, but for its pronounced pragmatism - today, for the readers of my Telegram channel, we will analyze it together with the head of the Unmanned Systems Service at the ‘Bars-Sarmat’..

Russian millogger Alexei Zhivoff has nostalgia for the good old days of early 2023 before the small drone revolution completely changed the landscape of the War in Ukraine.

“Drones That Changed Everything,

Nostalgia

Spring 2023, the left bank of the Kherson River.

“The enemy is no more than five kilometers away as the crow flies. We maintain night camouflage and head to the rear positions of the airborne troops. Driving at night without headlights is a special ‘pleasure.’
2/
“I already understand: before drones, arriving at the front lines was literally ‘war in luxury style.’

The next day, we reach the road along the Dnieper. The enemy is no more than two kilometers away from this road—technically, driving is allowed.

Ukraine’s Minister of Defense Mykhailo Fedorov reports that SpaceX and Elon Musk have quickly agreed to resolve the Russian UAV use of Starlink satellites.

“The Ministry of Defense, together with SpaceX, is already addressing the issue of using Starlink on Russian UAVs.
1/ Image
“A few hours after the appearance of Russian drones with Starlink connectivity over Ukrainian cities, the Ministry of Defense team promptly contacted SpaceX and proposed solutions to this problem.
2/
“I am grateful to SpaceX President Gwynne Shotwell and Elon Musk personally for their quick response and the start of work on resolving the situation.

Fresnel zones significantly affect control and video communications with FPV drones.
Fresnel zones are volumes of space between a transmitter and receiver in which any obstacles interfere with a signal even if radio line-of-sight (LOS) is clear.
1/ Image
Trees, buildings, terrain, and even vehicles within this zone can interfere because radio waves propagate as expanding wavefronts.
Waves therefore arrive at the receiver via slightly different paths, but they interfere constructively if the zone is clear.
2/ Image
Obstacles within the zone cause diffraction (bending or scattering of waves around edges), so some waves arrive out of phase.
They also cause reflections, in which secondary signals bounce off the obstacle and interfere destructively with the direct signal.
