The first naval battle of uncrewed boats in history — the Ukrainian Sargan gunned down a Russian USV

For the first time, a combat engagement between two naval drones has been recorded. In the Black Sea, the Ukrainian surface drone Sargan 3000, equipped with a Protector remote weapon station with a 12.7-mm machine gun, detected and sank a Russian uncrewed boat. The Ukrainian Navy conducted the operation jointly with HUR: reconnaissance detected the target, and the boat destroyed it (source).

Judging by the footage, the Russian boat was unarmed, which allowed the Ukrainian USV to come close and fire at point-blank range (source). The event marks a new class of tasks for surface drones — not only strikes on ships and infrastructure, but also fighting their own kind. Russian commentators openly admit lagging behind in this segment: the UAVDEV channel points out that the bet on the expensive "Zefir" USV slowed the development of the entire industry, while the Ukrainian side is already building coastal defense on a combination of USVs and mesh modems (source).

Northrop Grumman and SandboxAQ for the first time combined magnetic and visual navigation on an expendable strike UAV

The AQNav system was tested on the Lumberjack jet drone, adding a magnetic channel based on quantum sensors to the previously announced visual navigation. According to SandboxAQ, this is the first publicly announced demonstration of combining MagNav and VisNav on a single-use strike platform (source).

Magnetometers measure weak changes in the magnetic field of the Earth's crust, and the software matches them against an anomaly map — the channel needs no satellites, lighting, or surface visibility, which provides correction of the inertial system when GPS is unavailable, including over open water. The software was installed in existing onboard systems in less than an hour. At the same time, positioning accuracy, the duration of the GPS-free segment, and sensor characteristics have not been disclosed — the claim of "immunity to interference" applies only to the magnetic channel, whose quality depends on the maps and on extracting the useful signal. The topic of GPS-free navigation is becoming multi-layered on the Ukrainian front as well, where jamming and spoofing are everyday reality (source).

update Jet-powered "Gerans" climb to 5–7 km to get out of the zone of most Ukrainian air defense assets

The Russian side has changed the employment profile of jet-powered "Gerans": instead of flying close to the ground, the vehicles periodically climb above 5 km, and in some cases were recorded at 7 km. The logic is not stealth — at that altitude the drone is clearly visible to radars — but taking the target beyond the reach of a significant part of Ukrainian air defense assets (source).

According to the cited analysis, the German Gepard is effective up to about 3.5 km, the Skyranger 35 — about 4 km, Stinger and Piorun — up to 3.5–4 km, the "Strela-10" — about 3.5 km, IRIS-T SLS and Mistral 3 — up to 6 km. Anti-aircraft interceptor drones also struggle at 7 km: a propeller-driven system works worse in thin air. What remains are the "Buk", FrankenSAM, and IRIS-T SLM, but spending scarce expensive SAMs on the "Geran-4" is economically unprofitable. Separately, Serhiy "Flash" notes that in rainy weather the jet-powered "Shahed-Siker" loses the ability to acquire targets from 3–6 km, and the AI-based optical navigation of the "Molniya" stops working — but it is precisely in bad weather that interceptors also have a harder time (source).

update "Shaheds" are being upgraded in inertial navigation and are switching to 20-element CRPA antennas

According to Serhiy "Flash", some of the attacks with jet-powered "Shaheds" on Kyiv are carried out not in online control mode but on traditional satellite navigation, and a few weeks ago the enemy upgraded the inertial navigation system on the "Shaheds" to reduce the impact of EW (source).

This month, 20-element CRPA antennas are expected to appear on "Shaheds" instead of 16-element ones, and VNIIR-Progress will begin producing 24-element antennas in 2027. As a separate point, the source notes: the "Banderol" and "Dan-T" cruise missiles have no online control system, only satellite and inertial navigation, and EW is named as one of the options for countering them.

The Russian foam "Sokol" interceptor — with a remotely detonated warhead, which prohibits its use inside Russia

Footage and details have appeared of the cheap Russian "Sokol" interceptor drone, nicknamed the "foam drone". The vehicle is designed for mass use and is attached to mobile fire groups, but the scale of its use is unknown (source).

The key feature: the "Sokol" is not kinetic, but carries a warhead that the operator detonates at a distance from the target being intercepted. Precisely because of the warhead, according to the source, the drone cannot be used on the territory of Russia itself — its laws prohibit drones with a warhead. For comparison, the "Yolka" interceptor (1.3 kg, up to 230 km/h) works by kinetic ramming with AI terminal guidance to a vulnerable point of the target (source).

Infected Drones — 15 write-ups of attacks from a compromised aircraft on the operator's ground station

A repository has been published with 15 write-ups of vulnerabilities in ground drone control software: QGroundControl, Mission Planner, MAVSDK, MAVROS, MAVProxy, and DroneKit-based applications. The main scenario is that a compromised aircraft sends specially crafted data to the program on the ground, and errors in processing it allow writing files, executing code, and disrupting the station (source).

Specific results: in QGroundControl 5.1.3 under Windows, file writing occurs upon simple connection, and code executes on the user's next login; in Mission Planner, downloading a file via MAVFTP writes it outside the selected folder; in MAVSDK 3.17.4, about 153 KiB of compressed data expand to 1 GiB on disk; in MAVROS, the leak of process memory contents amounted to 47 800 bytes. A practical conclusion for operators working with captured aircraft: connecting and reading data require an isolated workstation, since even a camera name, metadata, and the onboard log can contain attack data. [TECH] in the post — reproduced scenarios for specific software versions.

The insides of the "mini-fipi" — a Luneburg lens and an extractable flight plan

The "mini-fipi" decoy, which the Russian source calls an enemy one, has been taken apart: part of the flight plan can be extracted from the vehicle (the flight over Russian territory is preserved, over Ukrainian territory it is wiped), the tail number is approaching 10000, and a Luneburg lens is installed to increase radar visibility (source). [TECH] in the post — links to a method of making a Luneburg lens by 3D printing to increase the RCS of small UAVs.

Poland's Ala.com showed the Husaria A3 FPV interceptor carrier based on a "Geran" analog

At MSPO 2026 in Kielce, the Polish company Ala.com presented the Husaria A3 carrier drone (in the source's wording — made from a "Geran" analog) for engaging piston-powered propeller drones. The vehicle stays in the air for more than 10 hours at altitudes of up to 5000 m, carrying four to six Pika A1 interceptor quadcopters (warhead 200 g, up to 350 km/h, ceiling 6000 m, radius of at least 4 km, up to 8 minutes in the air) (source).

One operator controls a swarm of six carriers, AI distributes the targets, and a human makes the decision to release an interceptor; acquisition and engagement are automatic. Russian commentators note that the concept of interception from a carrier UAV makes it possible to hit drones at a safe distance, reducing ammunition consumption and the need for experienced operators, and are surprised at the absence of an analog in Russia.

Tactical Technology showed S.O.V.A.-2.0 — multi-layered protection of armored vehicles from drones

The Ukrainian company presented the S.O.V.A.-2.0 system for protecting armored vehicles from strike and reconnaissance UAVs, combining several layers (source). The Blood Seeker radar with an AESA detects aerial targets, radio frequency monitoring assets determine their characteristics, and MOROK EW systems suppress control channels. For targets immune to EW, electro-optical tracking and physical destruction are provided: the ZHNETS-M 240 combat module fires at 300–800 m, and the ZOREPAD-6P system intercepts drones with a net at close range.

Rostec showed the AIM "BM V-01" counter-drone system, but the rental price drew criticism

At the forum in "Patriot" park, Rostec and "Roselektronika" presented the AIM "BM V-01" system: a radar with 5 km range, automatic tracking of 64 targets, EW in the 100–6500 MHz band, a 30-mm cannon with a rate of 550 rounds/min (source). The declared rental cost is 25 million rubles per month for guarding one facility.

Criticism from Russian channels comes down to economics and survivability: for an FPV operator there is no difference whether it is an expensive vehicle or a cheap pickup, and for 25 million a month one could assemble a whole fleet of pickups with anti-aircraft mounts. Separately, questions are raised about the maintainability of complex electronics in frontline conditions.

As a separate story: mobile fire groups are named the main Russian means of fighting drones — a crew of two or three people with a heavy machine gun is given up to five seconds to react (source).

The T-80BVM received serial cable protection against FPVs to replace the "tsar-mangals"

Uralvagonzavod developed and introduced into series production an "assault kit of all-aspect protection" made of high-strength steel cables for the T-80BVM — previously such items were made by the crews themselves and by field repair units (source). The point of the transition: heavy frames with sheets ("tsar-mangals") overloaded the power plant and suspension, deprived the tank of mobility, and prevented the crew from using observation devices. The cable design acts as a shield and prevents an FPV drone from hitting the vehicle's hull. In parallel, a batch of T-90M and T-72B3M tanks with a changed shape of mangals went to the troops (source).

The VoronPTT messenger — a secure push-to-talk radio on the organization's own server, without personal data

The corporate messenger VoronPTT with a walkie-talkie mode, running on the organization's own server without external internet, is in closed testing (source). According to the developer's document: hundreds of subscribers, server deployment in 20–30 minutes, PTT latency of 1–2 seconds, zero subscription fee, and a complete absence of personal data — instead of names, anonymized hash labels; encryption keys are generated on the phone and never leave the device.

Key for combat use: operation over a local network without internet and end-to-end encryption, in which hacking or seizure of the server yields only encrypted blocks without keys. The developer honestly lists the limitations: the system does not hide the fact of exchange itself (labels and time are visible to the server), does not protect an unlocked phone, and does not allow revoking access from a single device — only by changing the network key for everyone at once. Versions for Windows and Android have been tested; Linux and single-board computers are next in line.

The Ukrainian "Liut" UGV shows up to 55 km off-road and 120+ km on highways via Starlink

In a translated interview with the head of Ukraine's UGV Robotics, KCPN documented the evolution of the AFU's ground robotic systems (source). By 2026 the AFU moved from logistics platforms to the systematic use of combat ones: strike robots work in tandem with FPV cover modules and wait in ambush at observation posts. Starlink terminals have become standard, which makes it possible to control a robot 20–40+ km from the front edge; upgraded "Liut" vehicles achieve up to 55 km off-road and over 120 km on hard surfaces, 70–80 km in real conditions. The 6 mm armor (Armox, STANAG 2 standard) withstands 5–6 close FPV hits and detonations of anti-personnel mines. This contrasts with the previously noted decline in robot survivability — here it is about an increased operating radius thanks to satellite communications.

update A Lancet with IRRA AI guidance hit a Ukrainian Sky Sentinel weapon station

A ZALA "Lancet" crew destroyed a Ukrainian Sky Sentinel remotely controlled turret with a loitering munition featuring the IRRA intelligent guidance and target recognition system (source). What is new here is not the "Lancet" itself, but the specific use of IRRA autonomous terminal guidance against a robotic firing point, which places the product in the trend of AI interception in the terminal phase.

The US is moving classified AI workloads off Anthropic, accusing the company of restrictions

The Pentagon has almost completed (about 90%, the finish is the end of October) the removal of classified workloads from Anthropic models (source). The reason is a conflict: Anthropic sought a ban on using its models for mass surveillance tasks and fully autonomous lethal systems, while the Pentagon insisted on the right to use the software for "any lawful purposes". The company was placed on the supply chain risk list, and the parties are in litigation. The department is moving to a multi-model ecosystem (OpenAI, xAI Grok), acknowledging dependence on a single supplier as a strategic mistake; at the same time, officials note that the GenAI.mil platform is still inferior to commercial counterparts. This directly echoes the Russian discussion: DARPA&CIA and mil_hub argue that military tasks need models with minimal censorship, and propose taking open Chinese models into a closed loop (source).

What to watch

• Naval warfare has reached a new level: drones have begun fighting drones. The first USV-versus-USV battle stakes out a whole class of tasks where surface robots become both hunters and targets at the same time.

• Jet-powered "Gerans" have found a simple counter to saturated Ukrainian short-range air defense — climbing to 5–7 km, where only scarce, expensive ballistic SAMs work. The economics of interception is again shifting against the defender.

• The race for anti-jam satellite navigation is accelerating: the "Geran" is switching to 20-element CRPA antennas with a plan for 24 elements by 2027, and the inertial channel is being upgraded in parallel. EW remains a working tool, but the window is narrowing.

• AI has finally established itself as a military-technical target and tool: the Anthropic report documents the use of Claude for missile development (Yemen, range 2000+ km), collection of data on the US fleet (Iran), and cyberattacks on Ukrainian drone companies (Russia). The threshold for creating guided weapons is falling.

• The rift around Anthropic shows: the Western military-industrial complex is not ready to accept the ethical restrictions of AI vendors, and Russian analysts are already openly betting on open Chinese models for a closed loop. The gap in military AI is growing faster than in any other technology.

What's new in UAVs and counter-UAV

• The first USV-versus-USV battle: the Ukrainian Sargan 3000 with a Protector module sank a Russian uncrewed boat.

• AQNav (Northrop Grumman/SandboxAQ) — the first demonstration of magnetic + visual navigation on the Lumberjack expendable strike drone.

• Jet-powered "Gerans" at 5–7 km leave the zone of most short- and medium-range air defense assets.

• The Russian "Sokol" interceptor with a remotely detonated warhead — because of the warhead, it cannot be used over Russian territory.

• Husaria A3 (Poland) — carrier of 4–6 Pika A1 FPV interceptors, up to 10 h in the air, a swarm of six carriers per operator.

• S.O.V.A.-2.0 (Ukraine) — multi-layered protection of armored vehicles: Blood Seeker AESA radar, MOROK EW, ZHNETS-M 240 module, ZOREPAD-6P net.

• AIM "BM V-01" (Rostec) — 30-mm cannon, EW 100–6500 MHz, 64 targets; criticized for the rental price of 25 million ₽/month.

• Cable protection against FPVs has gone into series production on the T-80BVM (UVZ).

• A "Lancet" with IRRA AI guidance hit a Ukrainian Sky Sentinel turret.

• The US Air Force requested information on a ground-based medium-caliber anti-aircraft gun against drones of all groups and subsonic cruise missiles.

Military space and space-based data

The US Space Force approved the third node of the DARC deep space radar — in Texas. The site near Lake Kickapoo will complete the American-British-Australian geostationary orbit monitoring network; construction from 2027, commissioning — 2030 (source). A network of three dispersed radars will provide round-the-clock all-weather tracking of objects at an altitude of about 36 000 km with triangulation, oriented toward the growth of China's space capabilities.

The Pentagon is looking for an AI system to forecast space threats. DIU is collecting proposals for a system to analyze and predict threats in orbit (source) — the Pentagon increasingly views space as a priority and vulnerable domain.

Iran received satellite images of an American base from Chinese companies before the strike. According to the WSJ, US officials linked high-quality satellite images obtained by Iran from Chinese companies to the July 17 missile strike on Muwaffaq Salti Air Base in Jordan (three US service members killed); the images were obtained both before and after the attack (source). At the same time, specific companies were not named, and no direct involvement of the Chinese government was claimed. Officials call this the most convincing evidence that Chinese support led to the deaths of military personnel; separately, concern was expressed about Iran's ability to track moving US ships. China rejects the accusations. This is an example of how commercial remote sensing is becoming a targeting tool.

Russia is promoting a BRICS space council with satellite data exchange, joint missions, and use of orbital networks (source) — a bid for an alternative loop of access to space data.

Data access: an enthusiast launched the site findrassvet.ru for tracking the Russian "Rassvet" satellite constellation — with an archive of orbital elements, a 2D/3D map, and catalog updates 3–5 times a day (source). This is an OSINT tool that makes the movement of the constellation's spacecraft publicly trackable.

Under the radar

The US Army shut down the IFPC-HEL combat laser in favor of Navy developments. The US Army stopped independent development of a high-energy laser under the IFPC program; the decision was revealed in a Pentagon request to reallocate $2.9 million of the FY2026 budget; earlier, in 2024, the purchase of demonstrators worth $4.8 billion had already been canceled (source). A signal of the difficulties in bringing Army combat lasers to series production — against the backdrop of a general rise in interest in C-UAS.

The US Army allocated ~$196 million for EW sensors — the first production contracts under the REWSI program. $99 million — to Heaviside Industries for the compact MOTH spectrum analyzer, $96.9 million — to Research Innovations for Dragonfly AI sensors integrated with the Intrepid drone (source). The Army is moving from proprietary systems to off-the-shelf market solutions in the electromagnetic spectrum.

The Houthis used Claude Code to design three missile platforms, including a ballistic one with 2000+ km range. An Ansar Allah engineering cell used AI to write navigation software and integrate civilian processors into onboard autopilots, splitting tasks between isolated sessions to bypass filters (source). There are no finished ballistic prototypes yet, but the precedent lowers the technological threshold for creating guided weapons.

The University of Arizona patented TriSPADE "lensless vision" optics — target classification without forming an image A University of Arizona patent application describes passive optics made of interferometers and mirrors that decompose the light flux into spatial modes, which AI matches against a dictionary of targets (source). Cheap optics instead of giant telescopes make it possible to put the system on CubeSats and drones; vulnerabilities are phase fragility and the inability to recognize a fundamentally new target. [TECH] in the post — the operating principle of TriSPADE and an overview of related systems (SYNAPLEX, Thales TALIOS).

And what about our Chinese comrades?

China is building a copy of an American Arleigh Burke destroyer as a target ship. Satellite images from September 7 at the Jiangsu Dayang shipyard show a superstructure imitating the silhouette of a US destroyer or ships of Japan and South Korea (source). The goal is to bring tests of seekers, radars, and UAVs as close as possible to real combat conditions against enemy ships in the western Pacific.

The BG 5 bionic robotic fish for underwater reconnaissance. At an exhibition in Beijing, a 3 kg vehicle with seven body sections and three movable tail joints was shown, moving without the jerks and noise characteristic of underwater drones (source). 5 hours of autonomy, a nose sonar for real-time monitoring; the main advantage is camouflage as a live fish for covert surveys of water areas and infrastructure.

The Shenyang institute revealed the autonomy concept of a next-generation fighter. Researchers at the Shenyang Aircraft Design and Research Institute described the aircraft's ability to continue flight if the pilot loses consciousness, navigation without satellites (quantum technologies), and control of swarms of uncrewed wingmen with autonomous re-formation (source). The organization is linked to the development of the J-50, but the document does not name the J-50 directly and does not confirm that these technologies will be installed on it specifically.

China is accelerating the path from lab to series production. Illustrative examples: the NIO plant in Hefei, where AI participates in about 80% of production decisions, and CanSemi, which reached production output in 18 months (source). For the UAV industry, the speed of commercialization is becoming no less important than the vehicle's specifications themselves.

External analysis

The Anthropic report is the most substantive item on military AI of the day, broader than what the Russian-Ukrainian sphere provided. The War Zone analyzes the 154-page report: an Iran-linked group used Claude to gather intelligence on US fleet positions (ship identifiers, transponder data, personal information about service members), and a Yemeni cell used it as a replacement for programmers in developing guidance systems for 2000+ km missiles and a hypersonic glider (source). The Kyiv Independent separately documents Russian use of AI for cyberattacks on Ukrainian drone companies and their supply chains (source). Russian-language channels mentioned these cases in digest form, but without detailing the scale.

Simultaneous Iranian control of two key oil arteries — a scenario the Telegram sphere underestimates. The War Zone points out: a drone attack on the Saudi East–West oil pipeline and the Houthi seizure of Perim and Zuqar islands in the Bab el-Mandeb create a real threat of blockading Middle East oil exports via both Hormuz and the Red Sea at once (source). This moves the Yemeni success from local to geo-economic.

Simultaneous multi-domain attacks exposed gaps in American air and missile defense. Breaking Defense: the conflict with Iran showed that even a generally effective system suffers real damage from synchronized strikes across several domains, which forces a rethinking of the layered defense concept (source). A direct parallel with Ukraine's problem of intercepting ballistic missiles and jet-powered "Gerans".

The US Air Force is returning to anti-aircraft artillery against drones. Task & Purpose analyzes an RFI for a ground-based medium-caliber gun to engage UAVs of all groups and subsonic cruise missiles, with an emphasis on low cost per shot and massed fire (source) — the same interception economics logic that makes Russian mobile fire groups bet on heavy machine guns rather than expensive systems.

Link 16 recognized as a critical condition for coalition interoperability at the Pitch Black 2026 exercise. Janes: countries without this link (India with Rafale, Thailand with F-16) faced limitations, while the Philippines activated Link 16 on the FA-50 for the first time, and South Korea — on the KF-16V (source). Network integration is becoming no less important than the generation of the platform itself.

Conflict development — in brief

The negotiation track has been outlined but runs up against territory: US special envoy Kushner stated that to end the conflict the AFU needs to withdraw along the line outlined in the Kremlin, and that otherwise the peace agreement is ready; so far Ukraine does not want to do this (source). Lavrov stated that Russia will not halt the SMO for the duration of negotiations (source).

At the front — a dynamic situation near Lyman: according to ISW and Russian sources, Ukrainian counterattacks by small groups supported by UAVs may have eliminated the Russian salient north of Lyman and pushed troops back to Zherebets (source). Barantchik soberly assesses this as a deterioration of the Russian operational configuration north of Sloviansk, but not as a "turning point of the war" (source).

Harbingers of escalation: Russia is preparing up to 3000 piston-engine "Gerans" for multi-day strikes on the western regions, waiting for non-flying weather; today's raid by dozens of ordinary propeller-driven "Gerans" reached almost to the Polish border (source. An indirect indicator is Russia's expansion of military medical infrastructure by 16–20 thousand beds, mainly near the Baltic states, which is typical of preparation for an increase in the intensity of hostilities (source).
