Ukraine says Russia launched 433 drones in one night and 371 were neutralised; a switch to piston Shaheds under cloud cover, and a third refinery struck in three days

The composition of the 433 and impacts at 16 sites

According to the Air Force, 64 of the 433 were jet-powered, launched from Oryol, Kursk, Shatalovo, Bryansk, Millerovo and occupied Donetsk. By 07:30, 371 drones including 47 jets had been shot down or suppressed by aircraft, surface-to-air missiles, electronic warfare, unmanned-systems units and mobile fire groups, with impacts at 16 locations and debris at 14. More than 40 drones were still airborne at the time of the statement, and no missiles were reported.

Damage included energy infrastructure in Vinnytsia and Kyiv regions, four injured in Rivne, a child injured in Poltava and five houses in Lviv, and the Energy Ministry said parts of eight regions were without power on Saturday morning. President Zelensky said in his weekly summary that almost 2,000 drones and 44 missiles had been used in the past week. The kill and suppression figures are the Air Force's own and remain unverified independently.

Cloud cover against interceptor crews, and an upgraded ZIRKA that tracks by computer vision

Defense Express and electronic-warfare specialist Serhii Beskrestnov point to the piston-heavy composition of this raid. Interceptor-drone pilots rely heavily on visually acquiring the target, and thick cloud degrades the conditions for chasing slow targets, so Russia appears to have used the weather to blunt interceptor effectiveness. This is one analyst's inference and Russian intent is unconfirmed, but it suggests a pattern of alternating jet raids and mass piston raids according to weather.

On the defending side, a unit of the 412th “Nemesis” Brigade of the Unmanned Systems Forces was reported on 1 November to have downed a jet-powered Geran-5 flying at about 400 km/h at roughly 3,500 m with an upgraded ZIRKA interceptor. The aircraft runs a trained computer-vision model on a Raspberry Pi 5 that detects Shahed-type features at about 1 km and tracks autonomously after operator confirmation. Date and place of the intercept were not given, so the claim rests on footage. Coping with cloud and onboard autonomous tracking define the interceptors' next tasks at once.

The Kstovo strike and a private company claiming it

In the early hours of 1 November explosions and fire hit the Lukoil NORSI refinery at Kstovo in Nizhny Novgorod region, with a capacity of 15–17 million tonnes a year. Governor Gleb Nikitin described a massive drone attack that significantly damaged an industrial facility and claimed more than 100 drones were downed. Fire Point, maker of the FP-1 long-range drone, claimed the strike without giving numbers or damage. No General Staff confirmation had been found by Saturday evening; the strike itself is corroborated by the governor and multiple monitoring channels, while the extent of damage awaits satellite imagery.

The strike overlaps with the Wall Street Journal's 29 October report of a pause in refinery strikes at the US administration's request. Kyiv officials told the Kyiv Independent that no such order existed and only a brief pause occurred, while Russian Deputy Prime Minister Novak said Ukraine had resumed attacks on three refineries and a gas-chemical complex. Satellite analysis assesses that the 30 October strike on the Novokuibyshevsk refinery in Samara region damaged both primary distillation units and halted all primary processing.

About 60 deep strikes in October at a median 551 km

Militarnyi's geospatial tally counts about 60 geolocated deep strikes in October: 20 on oil and gas, 10 on military sites, 9 on defence industry, 9 on infrastructure, 6 on chemicals, 4 on logistics and 2 on power. The median distance from the front was 551.5 km and the maximum 2,508 km at Omsk; at least eight combat aircraft (seven Su-34 and one Su-35) were confirmed destroyed, and Russia acknowledged eleven aircraft lost in October. Neptune was used in three strikes and Storm Shadow at Oryol and Yelets. The run of refinery strikes extends this distribution.
