Russia's largest drone attack hits 11 regions

The largest single drone attack of the war hit 11 Ukrainian regions in rare daytime waves, killing at least eight people as the spring offensive gathered force.

Key takeaway

Russia launched its largest ever drone barrage precisely when US interceptor stocks were split between two wars.

Russia launched 948 drones at Ukraine on 24 March, the largest single drone attack since the full-scale invasion began in February 2022⁠1. Strikes hit 11 oblasts in rare daytime waves, killing two people in Ivano-Frankivsk, two in Poltava, and one each in Vinnytsia, Zaporizhzhia, Kherson, and Kharkiv.

The barrage dwarfed the previous record of 430 drones and 68 missiles on 13-14 March and continued a trajectory that saw 9,616 kamikaze drones launched on 17 March alone. Daytime attacks are operationally different from night strikes: thermal detection works best against dark skies, while cluttered urban environments in daylight demand radar-guided interception instead. Russia appears to be testing whether saturating both halves of the 24-hour cycle can overwhelm Ukrainian air defence scheduling.

Zelenskyy told the BBC two days later that 800 US-made interceptors were consumed in three days of the Iran war, against 700 Ukraine received over its entire winter. With American production at 60 to 65 Patriot rounds per month, replacing those 800 takes a full year. Russia's spring offensive launched in the window of maximum interceptor scarcity.

In Lviv, a UNESCO World Heritage city 750 kilometres from the front line, the 16th-century Bernardine monastery lost its tower and the Church of St Mary Magdalene had its windows shattered⁠2. UNESCO dispatched experts to assess the cultural damage. The reach of the barrage, far beyond the eastern front, signals a deliberate effort to stretch Ukrainian air defences across the country's entire depth.

Deep Analysis

In plain English

Russia launched nearly 1,000 drones at Ukraine in a single day — more than double its previous record. Think of it as flooding every intersection in a city with cars at once: no matter how many traffic police you have, some will get through. Ukraine uses expensive missiles (think £1 million each) to shoot down cheap drones (think £10,000 each). Russia is betting it can exhaust Ukraine's missiles before Ukraine gets more. The timing matters because the US — Ukraine's main missile supplier — is currently using its own stockpile in a separate war against Iran.

Deep Analysis
Root Causes

Russia's drone escalation stems from three structural factors not visible in the daily headlines.

First, Iran's supply of Shahed-136 production licences in 2023 enabled Russia to manufacture at scale domestically, breaking its dependence on imported units and absorbing Western supply interdiction.

Second, Ukrainian air defence is fundamentally reactive: it must cover the entire country's depth, while Russia chooses when and where to strike. The 948-drone barrage across 11 oblasts simultaneously exploits that asymmetry.

Third, the Iran war created a window of US interceptor scarcity that Russia's military planners almost certainly anticipated from the moment American involvement in the Middle East became probable.
