Russia’s 255-Drone Barrage: The Inside Numbers on Ukraine’s Biggest Overnight Attack

Broader Campaign Context

The July 30–31 drone wave was not an isolated event — it was part of a larger shift in Russian tactics. On July 29–30, Russia simultaneously launched 74 missiles (many of them ballistic) and 284 drones — 358 total aerial assets — of which Ukraine downed 320 . The Institute for the Study of War (ISW) assessed that Russia is deliberately reducing the share of drones in its strike packages and scaling up ballistic missile salvos to exploit Ukraine's acute shortage of Patriot interceptors, which are the only systems reliably capable of shooting down ballistic missiles like Iskander-M and Kh-47M2 Kinzhal .

The broader campaign has consistently targeted:

• Military-industrial facilities (defense plants, repair depots)
• Civilian fuel and energy infrastructure (oil depots, power substations)
• Kyiv specifically, where ballistic missile penetrations have caused mass casualties

Strain on Ukraine's Air Defenses

Patriot interceptor shortage. By early July 2026, Ukraine had virtually exhausted its stock of Patriot PAC-3 interceptors — the only weapon that can reliably stop Russian ballistic missiles . During a major July 6 attack, Ukraine failed to intercept a single one of 23 Russian ballistic missiles, exposing Kyiv to devastating strikes . The simultaneous U.S.-led war in Iran has further burned through global stockpiles of PAC-3 interceptors (over 1,000 expended), reducing what is available to backfill Ukraine . President Trump granted Ukraine a license to produce Patriot missiles domestically in July, but experts say it will take at least a year to establish production lines and resolve technical agreements with U.S. defense contractors .

F-16AM loss. On July 29, Ukraine lost another F-16AM fighter jet. The aircraft was on a frontline combat mission intercepting Russian aerial targets when an in-flight emergency (described as a malfunction, not enemy fire) forced the pilot to eject; he survived and was evacuated . This is the fourth F-16 Ukraine has lost since receiving the type, underscoring the attritional toll on both platforms and aircrew as Ukraine's small F-16 fleet is pushed hard on daily interception sorties .

Overall air defense erosion. Ukraine's air defense network is being squeezed from two sides: Russia is firing a record volume of munitions (6,443 drones and missiles in July alone, the highest monthly total of the war) while simultaneously shifting toward ballistic missiles that Ukraine cannot stop without Patriot PAC-3s, which are in critically short supply . Drone interception rates remain high (~76–90%), but the ballistic missile gap is widening and directly translates into more deaths and damage in Ukrainian cities .
