Ukraine has approved a drone built to reach the deepest parts of Russia. Ukraine's Defense Ministry has codified the domestic Dovbush T40 uncrewed aviation complex, a strategic-level drone for deep reconnaissance and precision strikes on distant Russian targets, the ministry announced.

The drone extends the reach of Ukraine's homegrown deep-strike arsenal to Siberia. With a wingspan of nearly 5 meters, the Dovbush T40 has enough range to hit targets beyond the Urals and in Russian Siberia.

What the drone does

The Dovbush T40 is a multi-role strategic aircraft. It is designed for deep reconnaissance, fire correction, and precision strikes on structures, equipment, and enemy personnel far from the line of contact.

Its endurance is the enabler. More than a day aloft gives it the range to reach targets, letting Ukraine threaten the deep-rear sites, from factories to airfields, that Russia has kept far from the front for safety.

Its advantages over similar drones

The drone offers several edges, the ministry said. It has ultra-low radar visibility, a high-performance engine with electronic fuel injection, and a choice of strike methods, either as a kamikaze drone or by dropping a munition.

It is built to work under jamming. The Dovbush T40 stands out for high resistance to electronic warfare, according to the Defense Ministry, the recurring requirement for any Ukrainian drone meant to fly deep into a contested electromagnetic environment.

It builds on combat-proven predecessors

The drone comes from a maker with a track record. It was built by a Ukrainian enterprise whose Dovbush T20 and Kotyhoroshko drones have operated on the battlefield since 2022 with some of the highest effectiveness ratings.

The T40 is an evolution of a proven system. The medium-range Dovbush T20, used for reconnaissance, real-time artillery correction, and pinpoint strikes, evolved through battlefield feedback into the longer-range, more powerful T40. It joins a fast-growing domestic fleet: since the start of 2026, Ukraine's Defense Ministry has codified 413 uncrewed systems, almost all of which are Ukrainian-made.

A Ukrainian drone strike shut the plant that produces 40% of Russia’s liquefied petroleum gas on 10 August, and the country’s fuel crisis snapped back across at least 16 regions within days.

The shutdown of the Sibur ZapSibNefteKhim complex in Tobolsk, western Siberia, removes about six million metric tons of annual LPG capacity from a fuel system that was already under strain.

Gasoline restrictions had begun easing across Russia at the end of July, when Ukrainian drones temporarily shifted to other targets. When the strikes resumed in early August, fuel rationing returned immediately, the independent Russian outlet 7×7 reported.

Three industry sources told Reuters on Tuesday that the complex stopped operations indefinitely “while the extent of the damage and its consequences are being assessed.”

No LPG volumes were offered from the Tobolsk delivery point on Russia’s commodity exchange—a point that earlier this year handled about 4,000 metric tons of propane-butane mix per day. Sibur declined to comment.

A strike on one unit stopped the entire plant

Tyumen Oblast Governor Aleksandr Moor confirmed a fire at an industrial site following a drone attack but did not identify the facility.

Ukraine’s Special Operations Forces Deep Strike units, working with the Russian insurgent movement Chornaya Iskra (Black Spark), claimed the strike. The plant sits more than 2,200 kilometers from the front line.

Militarnyi’s OSINT analysis identified the specific target as the complex’s central gas fractionation unit—the plant’s entry point, where raw hydrocarbons are separated into usable products before anything else in the production chain can run. About half of ZapSibNefteKhim’s output feeds Sibur’s own petrochemical complex in Tobolsk; the rest goes to market.

Sibur held contracts to supply feedstock to defense-industry enterprises, including the Kamenskiy Kombinat, which produces solid rocket fuel and motors for the Grad, Smerch, and Uragan rocket systems.

Sibur also supplied the Perm Gunpowder Plant, which makes charges for multiple-launch rocket systems, air-defense complexes, and cruise missile boosters, Militarnyi also reported. The Sverdlov Plant and Biysk Oleum Plant, both explosives manufacturers, were also Sibur clients.

Fuel rationing returned within days

Across at least 16 regions, the fuel restrictions that had briefly eased in July are back, 7×7 reported.

In Sochi—Russia’s most famous beach resort—Mayor Andrei Proshunin said on Telegram that fuel was available at only 38 of the city’s 58 gas stations. Deputy Mayor Vyacheslav Bauer told residents and tourists to use public transport or stop driving, the Moscow Times reported.

In Bashkortostan, authorities banned gasoline sales in canisters, leaving at least one resident unable to fuel his lawnmower—as he complained to regional head Radiy Khabirov during a televised address, a Bashkortostan outlet reported. Production at the Ufa petrochemical complex is unaffected by the drone strikes, Khabirov said.

Still, the shortage persists for a different reason: every time a drone-alert protocol is activated, fuel tankers halt en route to gas stations, regional official Elena Prochakovsky explained at a briefing reported by Prufy. Three districts remain in a fuel “red zone,” and 19 of 26 gas stations in Sterlitamak are operating.

Lipetsk Oblast Governor Igor Artamonov told residents not to expect improvement for one to two weeks, Lipetsk outlet Ploshchad reported. “If you can leave 10 liters unfilled, the person arriving on empty will thank you,” he said.

Russia’s fuel system was already breaking

The Tobolsk shutdown lands on an already fractured system. By mid-July, fuel rationing had spread to more than half of Russia’s regions. Ukraine’s drone campaign had struck Russian refineries 194 times in the first half of 2026 alone—eleven times the previous year’s pace—knocking nearly half the country’s refining capacity offline, Ukraine’s General Staff reported on 4 July.

Repair timelines keep slipping because sanctions block the spare parts Russian plants need. To plug the gap, Russia has banned gasoline exports, permitted lower-grade fuel, and begun importing gasoline from India and Morocco, refined from its own crude—shipping it 14,000 kilometers home because its refineries cannot meet domestic demand.

The Tobolsk shutdown removes more LPG output than any single strike of the war. Russia was already rationing fuel in more than half its regions before this strike.
