Weekly review, week to 20 September 2026

The week in three paragraphs

The main process of the week was the transformation of Russian jet-powered strike drones from an experiment into the backbone of the air campaign. Use of jet-powered "Gerans" grew from about 350 in June to ~2800 in August; in some massed raids they already make up half of the strike wave, and in speed and flight profile they have come close to a cheap cruise missile. Ukrainian air defense is responding by switching to jet-powered interceptor drones, and the "fast drone versus fast interceptor" race has for the first time moved from demonstrations to real shootdowns.

Technologically, the week was defined by two shifts. The first is the move of strike weapons' navigation away from the satellite signal: the US tested navigation by the Earth's magnetic field on an expendable drone, Russia is preparing the "Ariadna" radio beacon system, and the Ukrainian side is expanding Vermeer visual navigation. The second is that military AI showed both sides of its nature: an Anthropic report documented the development of swarm and missile software on commercial models, and a US AI intelligence error nearly provoked a strike on a civilian vessel.

Going forward, expect vertical escalation: "Gerans" at aircraft altitudes of up to 12 km take themselves out of the zone of short-range SAM systems, production is going underground in Alabuga, and the erasure of the boundary between drone and cruise missile will force the entire air defense architecture to be rebuilt. The space domain has moved into an open phase — the US has officially acknowledged weapons in orbit, and the time to deliver a satellite image to troops has shrunk to hours.

Main structural shifts

Jet-powered "Gerans" have become the dominant class of strike weapons, and this breaks the previous logic of air defense. The transition has been documented: in the AFU General Staff report for September 18, of 93 drones used, 46 were jet-powered source. Growth over the summer was roughly sixfold, to ~2850 in August with output of about 3000 per month source. The key consequence is that in a single strike package Russia mixes slow piston drones, decoys and jet-powered "Gerans" — air defense is forced to work simultaneously against targets whose speeds differ several-fold. [TECH] The "Geran-5" carries a warhead of about 90 kg over ~1000 km at speeds of up to 600 km/h, which in layout is closer to a cruise missile than to the former "moped" source.

The ecosystem of Russian strike drones is going underground and deeper, changing the math of retaliatory strikes. Based on published satellite images, the Ukrainian side estimates the underground construction in Alabuga at about 42,000 m² of future production capacity source. The approach largely copies the Iranian practice of sheltering production from a superior air threat source. If such underground workshops are built, effectively hitting them with Ukrainian kamikaze drones and conventional cruise missiles will become practically impossible. In parallel, a satellite exposed a drone port near Tsimbulova in Orel Oblast that has grown from scratch to 16 launchers for jet-powered "Gerans" with autonomous power from solar panels source.

Military AI has shown the real risks of its use before control over it has matured. An Anthropic report documented the use of commercial models by Houthi-linked operators to integrate autopilot software and trajectory simulations, as well as by Russian developers to create drone swarm control software which, according to Anthropic's assessment, could autonomously select targets and issue the command to strike without operator intervention source. The flip side is a case in which a US AI intelligence report about "nuclear cargo" on a Chinese bulk carrier turned out to be an error (the cargo was nut kernels), while an armed team was already preparing to board source. The general conclusion for both sides: commercial AI lowers the barrier to entry into military-technical work, but there are as yet no common rules for verifying the materials it creates.

Technology dynamics and trends

The "jet drone versus jet interceptor" race moved into the combat phase in a single week. The Ukrainian side showed the interception of a "Geran-5" by Wild Hornets' new STING S jet-powered interceptor — the footage has been published; the "Rubin" crew of the 1020th anti-aircraft missile-artillery regiment was operating source. Serhii Beskrestnov confirmed its effectiveness: its speed margin is sufficient for various targets source. The significance goes beyond the "Gerans": if the interceptors prove scalable, they could also be used against some cruise missiles of the "Banderol" class source.

Russia is responding by speeding up the target itself — the adaptation cycle is shrinking to weeks. On the "Geran-5" the jet engine is now located inside the fuselage, and an air intake has appeared source. At the same time, drones have moved to the altitudes of manned aviation — over Odesa jet aircraft were recorded at 6000–9000 m, near Kyiv at about 12,000 m, which is higher than the typical kamikaze ceiling of ~5 km source. A possible tactical novelty is a strike on one important target by a "flock": according to "Rybar", several dozen "Gerans" instead of one or two were launched at an enterprise in Kyiv's Sviatoshynskyi district, which may indicate that a new tactic is being worked out source.

Russian "Gerans" are systematically hunting Ukrainian radars: six radars hit since the beginning of September A map compiled by the Ukrainian side shows six radars hit since the beginning of September, including the 35D6, P-18, P-19MA and 79K6 source. A qualitative shift: whereas previously problematic drones with Starlink were disabled by a complaint to the satellite communications operator, now the "Gerans" carry mesh modems and cannot be jammed so easily source. The Russian side notes that the opposing side can for now effectively counter them only with air-to-air missiles, which are in short supply source.

Satellite-free navigation has become the main vector on all sides of the theater of operations at once. The American side carried out flight tests of navigation by anomalies in the Earth's magnetic field on a Lumberjack expendable drone with the AQNav system — the software was integrated in less than an hour, and the system emits nothing source. [TECH] The principle is simple: position is determined from a magnetic map, as from terrain, and such a picture cannot be jammed by radio interference source. Russia is developing an intermediate solution — the "Ariadna" radio beacon system with a claimed accuracy of 15–20 cm and a range of up to 100 km deep into Ukrainian territory, which is being considered for installation on "Gerans", guided glide bombs and missiles source.

The bet on visual and anti-jam navigation is growing, but in protecting long-range drones Ukraine is in places catching up. The ~600 g VPS module from the American startup Vermeer compares the picture from two to four cameras with a loaded 3D map, emits no radio signals and, according to the source, is actively used in deep strikes on Russian territory source. At the same time, the 8-channel Orion 8 CRPA antenna presented by KORT is a catch-up solution: 16-element antennas with a controlled reception pattern were recorded on Russian "Gerans" as early as 2025 source.

Counter-drone efforts are diverging toward two poles: cheap passive acoustics and expensive multi-sensor integration. The barrier to entry into acoustic detection has fallen sharply — a student published the open-source VolAnti detector on an ESP32-S3 chip costing about 7 thousand rubles, which reliably detects a hovering quadcopter at 104 m with a response time of 0.23 s source. [TECH] Economics are decisive here: one acoustic sensor costs $400–1000, a network of 9500 sensors costs less than $5 million, while a single Patriot missile costs $4–10 million, and the sensors themselves are passive and cannot be jammed source. At the other pole are "matryoshka" interceptors such as Spain's Drizzle, where a carrier delivers up to four small interceptors to an area 80 km away source, and radars for direct drone detection against fiber-optic FPVs (Israel's Arbe Alerion) source.

Automation of fire against drones is reducing the human role in the interception cycle. Russia's Kalashnikov showed the "Zveroboy" system with "Kraken" FPV interceptors and the "Kalitka-KA" automated turret for the PKT machine gun, claiming 200+ drones shot down in three months on one axis source. The Ukrainian side is responding with the automated turret of the "Oberih" unit of the "Pomsta" brigade, where automation itself acquires and tracks the target, leaving the operator only the shot source. The common trend on both sides is the compression of the "see — recognize — strike" cycle, where the human is left with confirmation.

The campaign against Russian oil refining has produced a structural rather than one-off effect. Strikes target key primary processing units rather than areas: at TANECO, the ELOU-AVT-7 unit was hit, whose loss could deprive the plant of 52% of its primary processing capacity source; at the Yaroslavl refinery, according to Reuters sources, AVT-3 (40%) was hit in addition to AVT-4 (33%), knocked out at the end of August, and the plant is running at 27% of nameplate source. [TECH] The qualitative shift lies in the nature of the targets: damage to primary processing is repaired in one to two weeks, but serious damage to catalytic crackers and hydrotreaters requires six to eight months of repairs under sanctions source.

Space domain: the time to deliver an image to troops has shrunk to hours, and orbital confrontation has entered an open phase. America's BlackSky reported that its fifth Gen-3 satellite transmitted a 35 cm resolution reconnaissance image less than 20 hours after reaching orbit, with onboard AI automatically classifying equipment source. The US for the first time officially acknowledged deployed "space control" orbital weapons, without disclosing the type of systems source. According to a Russian analyst, these are probably GSSAP inspector satellites rather than kinetic weapons source.

Access to space data is also changing — toward sovereignization. Poland announced that an ordered image is now received in minutes instead of more than 20 days three years ago, and by the end of the year it will deploy an Earth remote sensing constellation of nine spacecraft source. Finland's ICEYE, after a funding round of more than $1 billion, is expanding its radar (SAR) capabilities to meet states' demand for their own systems source. The trend is that states want dedicated reconnaissance satellites rather than buying images on the open market. A separate vulnerability signal, now for optical spacecraft: the Chinese side is capable of blinding the optics of satellites such as BlackSky Gen-3 with ground-based lasers, and HQ-29 interceptors cover their operating orbits source.

Weak signals (Under the radar)

• The Russian "Ariadna" system turned out not to have been shut down but to have been in development since December 2025, and now the adversary is considering its beacon navigation for installation on "Shaheds", guided glide bombs and missiles — a response to the inevitable degradation of GPS under EW source.

• A Starlink terminal under complete blocking of the satellite signal behaves strictly predictably: it scans 8 channels for ~8.26 s each and reboots after approximately 30 minutes 34 seconds; the stability of the interval points to a software link-loss timeout source.

• Bio-inspired autonomy is leaving the lab: it is proposed to embed the connectome of the Drosophila brain (166,700 neurons) in the control loop of a USV as a ready-made set of reflexes without training from scratch source.

• Passive lidar detects "radio-silent" drones at almost 1.5 km — critical against fiber-optic FPVs and autonomous aircraft, where radio-frequency means are powerless source.

• The five-channel VectorWarp passive radar on a KrakenSDR receiver with GPU processing bypasses frequency hopping and encryption via "delay-Doppler" maps, without emitting a signal of its own source.

• The open-source tactical mesh network OpenMANET is assembled from off-the-shelf civilian hardware (Raspberry Pi, Wi-Fi HaLow) as a cheap replacement for expensive Silvus, but without stealth or protection against jamming — a consumable, not a combat line source.

Vector projection and implications

High confidence: the share of jet-powered strike drones will settle at around half of the strike wave, and the altitude profile will rise. The growth dynamics and Russia's stated 50% goal are already confirmed by this week's data, and moving the engine inside the "Geran-5" fuselage shows that work on speed is continuing. The September increase in the share of piston aircraft is most likely explained by weather conditions and significant accumulated stocks of such drones and does not cancel the long-term trend source.

High confidence: the main problem for Ukrainian air defense will be working simultaneously against targets whose speeds differ several-fold. Mixed packages of piston drones, decoys, jet-powered "Gerans" and the "Banderol" cruise missile require different means of interception in a single raid. The answer will be scaling jet-powered interceptors (STING S, the SBU product) and bringing in aviation with air-to-air missiles, which are in acute shortage.

Medium confidence: satellite-free navigation will move from reconnaissance drones to mass strike weapons within 6–18 months. Magnetic navigation has already been flight-tested, Vermeer VPS is used in long-range strikes, and the adversary is so far only considering "Ariadna" for installation on "Shaheds", guided glide bombs and missiles. If the technologies mature, GPS spoofing and jamming will largely lose their value, which will require fundamentally new countermeasures — up to jamming magnetometric navigation, which for now is a task for fundamental science source.

Medium confidence: the fight will shift toward passive and optical sensors resistant to EW. Acoustic networks, passive IR detection (Anduril Wisp), lidar and passive radar do not reveal a position and work against drones in radio silence. This is a direct answer to the spread of fiber-optic FPVs and autonomous flight, where radio-frequency detection means are useless.

Medium confidence: underground drone production in Russia will make strikes on workshops ineffective and shift targets to logistics and input energy. Conventional drones and cruise missiles are powerless against ~42,000 m² of underground capacity in Alabuga, so the Ukrainian campaign will probably focus on launch sites, fuel and power supply rather than on the assembly lines themselves.

Low confidence: orbital confrontation will accelerate the deployment of inspector satellites and anti-satellite means on both sides. The official US acknowledgment of weapons in orbit removes moral constraints on China and Russia for similar steps. Programs such as GHOST-R and RRS-G are likely to accelerate, but specifics are deliberately classified, so the assessment remains a hypothesis.

External analysis (Western sources)

• Western analysts are more sober than the triumphant Ukrainian presentation of the first naval drone battle: the loss of one Russian USV is not critical in terms of attrition, but the precedent will inevitably accelerate the evolution of surface drone tactics on both sides source.

• Eric Schmidt formulates the main takeaway of the week more harshly than the Russian-Ukrainian sphere: it is not an individual innovation that wins, but whoever turns it into a mass product faster, and here the advantage is currently Russia's — growth of ballistic missiles to ~1300 per year, jet engines on drones, gliding guided bombs and the "Rassvet" constellation source.

• General Atomics showed the Wildfire drone to replace the MQ-9 Reaper with a target airframe price of less than $10 million and a combat radius of more than 4260 km — an industrial response to the Ukrainian logic of "combat mass" through its own cheap production rather than through scarcity source.

• Perseus Defense tested the Mk-III kinetic drone interceptor costing about $2500 with a range of up to 2 km, which hits the target with a physical impact without radio jamming — a direct answer to fiber-optic and autopilot FPVs that are immune to jamming source.

• Britain announced the first contracts of the Recce Strike program for more than 1000 small reconnaissance drones, with the aim of going from production to the front line in 24 months — a compression of the procurement cycle under the direct influence of Ukrainian experience source.

• A Leonardo DRS expert formulates a doctrinal C-UAS lesson: betting on one large radar is "all eggs in one basket"; it is easy to jam or destroy, and what is needed is a distributed network of heterogeneous sensors with redundancy for dead zones source.
