Ukraine has struck four valuable Russian targets. The Ryazan Oil Refinery in Russia, the “Nebo-U” radar station in temporarily occupied Crimea, a military echelon near Tokmak in Zaporizhzhia Oblast, and a troop concentration near Vovchansk in Kharkiv Oblast came under fire, Ukraine's General Staff reports.

The Ryazan Oil Refinery produces A-92/95/98/100 gasoline, diesel, TS-1 aviation fuel, and other petroleum products. It is the country’s fourth-largest oil processing plant. 

“The products of this enterprise are used by the Aerospace Forces of the Russian military,” the General Staff emphasized.

Following the strike, multiple explosions and a significant fire were reported.

Nebo-U can no longer monitor from Crimea

The “Nebo-U” radar station in temporarily occupied Crimea was also hit, significantly limiting Russia's ability to observe and manage military operations in the southern direction.

The Nebo‑U radar system can detect fighter aircraft at a distance of more than 400 km when targets fly at an altitude of 20 km. For lower-flying objects, the range is 65 km.

A military echelon in the Tokmak area of Zaporizhzhia Oblast and a concentration of Russian personnel near Vovchansk in Kharkiv Oblast were also struck.

These strikes are part of comprehensive measures by Ukrainian forces to weaken Russia’s capability to conduct missile and bomb attacks on Ukrainian territory.

Ukrainian special forces, working with Russian insurgents, report they destroyed two of Russia’s most advanced air defense assets in Rostov Oblast. The attack reportedly happened overnight on 28 September and was confirmed publicly on 31 October by Ukraine’s Special Operations Forces (SSO).

Ukrainian commandos say Buk‑M3 and Nebo‑U radar destroyed in covert operation

Ukraine’s Special Operations Forces announced they had taken out two major components of Russia’s air defense infrastructure — the Buk‑M3 surface-to-air missile system and the Nebo‑U early warning radar station — during a special operation carried out jointly with the Russian resistance group Chornaya Iskra (“Black Spark”). The hit occurred in Rostov Oblast, inside southern Russian territory, in the early hours of 28 September.

Euromaidan Press couldn't independently verify this report.

The military reported both systems were disabled and turned into “scrap metal.” They emphasized the strategic value of the strike, stating that the Buk‑M3 and Nebo‑U posed “a serious threat to the work of Ukrainian combat aviation in the frontline zone” and interfered with Ukraine’s deep strike kamikaze drone operations.

The Buk-M3 and Nebo-U

The Special Operations Forces said the value of each system is measured in hundreds of millions of dollars.

The Buk‑M3 is capable of hitting aerial targets at distances of up to 80 km and speeds of up to 3 km/s. Its engagement range spans from 2.5 to 80 km, with altitudes between 15 meters and 35 km.

The Nebo‑U radar system can detect fighter aircraft at a distance of more than 400 km when targets fly at an altitude of 20 km. For lower-flying objects, the range is 65 km. 

Ukraine’s military intelligence drones struck key Russian radars and a landing craft in occupied Crimea on 26 October. The drones evaded both missile strikes and small arms fire, continuing a targeted campaign to degrade Moscow’s air defense network.

Ukrainian Ghosts hit radars and landing craft in occupied Crimea

According to the Main Directorate of Intelligence (HUR) of Ukraine’s Defense Ministry, drones from its Prymary (Ghosts) special unit of  carried out new attacks in Russian-occupied Crimea, targeting and damaging multiple pieces of high-value military equipment, including three radar systems, and a Russian Navy boat.

According to the 26 October update from HUR, the strike destroyed the following Russian assets:

• a 96L6 radar from the S-400 Triumf air defense system,
• a P-18 Terek radar,
• a 55Zh6U Nebo-U radar,
• and a BK-16 landing craft.

Video released by HUR shows one drone dodging a missile fired from a Pantsir S1 system moments before striking a radar installation. Another scene captures a Russian landing craft attempting to fend off a drone with small arms fire before being hit.
