Ukraine’s Air Force reports it has repelled the largest Russian aerial assault since the outset of the full-scale invasion, intercepting 288 unmanned aerial vehicles (UAVs) and destroying nine cruise missiles during a combined overnight strike.
The attack, launched between the evening of 25 May and the morning of 26 May, involved 364 aerial assets in total, and marks the third consecutive night of intensive bombardment.
The nine air-launched Kh-101 cruise missiles were reportedly fired from Tu-95MS strategic bombers based in Russia’s Saratov region. Simultaneously, Russia deployed 355 drones, primarily Shahed-type UAVs and other decoys, launched from multiple directions including Bryansk, Millerovo, Kursk, Oryol, and occupied Crimea.
Ukrainian mobile fire teams and ground-based air defence systems shot down 233 drones, while a further 55 were disabled using electronic warfare systems. According to official statements, no cruise missile reached its intended target. However, aerial weapons impacted five locations, and debris from destroyed drones fell on ten others. A full assessment of the resulting damage is ongoing.
The scale of the strike underlines a wider Russian shift in strategy. According to analysis published by The Economist, drone saturation is now central to the Kremlin’s war fighting doctrine. Whereas thirty drones once represented a significant effort, Ukraine now regularly faces coordinated swarms involving several hundred unmanned systems.
Indeed, only one night earlier, on 25 May, Russia is believed to have launched 298 drones alongside 69 missiles. Ukrainian military intelligence has warned that Moscow could soon be capable of fielding 1,000 drones in a single assault. Production of Shahed drones, originally running at 300 units per month, is now reportedly achievable in less than three days. Captured documentation suggests Russia is working towards a manufacturing rate of 500 UAVs per day.
Ukrainian engineers examining downed drones report that newer models show greater resistance to electronic interference. The latest variants no longer rely on GPS, making them harder to jam. Some are reportedly guided using artificial intelligence, mobile internet, and even real-time communications via encrypted messaging platforms. In one instance, a recovered drone was found to be receiving flight data from a Telegram bot, according to engineers cited by The Economist.
Tactically, Russian UAVs now employ more sophisticated flight patterns, initially flying at low altitude to evade radar, then climbing to 2,000–2,500 metres when nearing urban targets. This evolution has prompted Ukrainian forces to expand their response arsenal, deploying helicopters, F-16 fighter jets, and interceptor drones alongside conventional air-defence assets.
Colonel Denys Smazhnyi of Ukraine’s Air Force stated that, despite ongoing adjustments, the drone threat continues to adapt rapidly. While mobile teams armed with light weapons once formed the bulk of Ukraine’s counter-drone effort, the increasing altitude and range of UAVs has necessitated a shift towards high-altitude and airborne responses.
Air defence around Kyiv is still reported to intercept up to 95% of incoming drones. However, the remaining 5% continue to inflict considerable damage when they break through. Western-provided Patriot missile systems are a key element of Ukraine’s layered defence network, but the availability of interceptors remains constrained.
With the United States now producing roughly 650 PAC-3 missiles per year—fewer than the number of ballistic missiles Russia is thought to be manufacturing—concerns have been raised about Ukraine’s ability to sustain defence against large-scale ballistic threats. Each Russian ballistic missile typically requires two PAC-3 interceptors to be reliably neutralised.
Ukraine currently fields at least eight Patriot batteries, though several are believed to be under repair at any given time. The country’s leadership has appealed for more systems and ammunition to maintain operational readiness amid escalating demand.
A senior Ukrainian official cited by The Economist said the country may soon be forced to pursue a survival strategy that integrates air defence with targeted strikes and broader deterrence. As Russia increases the tempo and volume of drone-led operations, the balance of pressure will likely hinge on whether Ukraine’s international partners can match rising needs with timely deliveries.
As of Monday morning, no new attacks had been recorded following the record overnight assault. Ukrainian forces remain on high alert, anticipating further mass strikes in the days ahead.
