Ukraine’s Defense Forces struck a Russian Nebo-U long-range radar in occupied Sevastopol and several other military targets in Russia and occupied Ukrainian territories during a series of overnight attacks on 13 August, the General Staff of Ukraine’s Armed Forces reported.

The strikes are part of Ukraine’s broader “Middle-Strike” campaign, which targets Russian military infrastructure beyond the immediate front line.

Nebo-U radar hit in Sevastopol

The most significant overnight target was a Russian Nebo-U radar station in Sevastopol, occupied Crimea.

The Nebo-U is a Russian long-range, three-coordinate radar operating in the meter wavelength range. It is designed to detect and track airborne targets, including aircraft, cruise missiles, and ballistic missiles.

The General Staff said disabling the radar weakens Russia’s ability to detect and track incoming aircraft, cruise missiles, and ballistic missiles, potentially making it harder for Russian forces to detect future Ukrainian strikes and giving Ukrainian weapons a better chance of reaching their targets.

The Nebo-U is estimated to cost around $100 million, making it a high-value Russian surveillance system.

The radar strike supposedly came during a broader Ukrainian drone attack on Sevastopol that also damaged energy infrastructure, according to Russian occupation authorities. The attack caused a citywide blackout before power was later restored through a temporary setup. Ukrainian drones also reportedly targeted the Balaklava power plant, one of Crimea’s two main power stations.

Earlier strikes hit Crimean military infrastructure

The General Staff also reported strikes on Russian military infrastructure in occupied Crimea on 12 August, including a control tower at the Saky airfield.

Ukrainian forces also struck a communications relay near Chornomorske used to control Russian Geran and Gerbera strike drones, according to the General Staff. It said the strikes weaken Russia’s ability to operate the military airfield and control its attack drones.

Russian logistics and supply sites targeted

Ukrainian forces also struck a Russian drone control center near Myrne in occupied Zaporizhzhia Oblast, a fuel and lubricants depot near Dovzhansk in occupied Luhansk Oblast, and an ammunition depot near Novyi Hai in occupied Zaporizhzhia Oblast.

Another strike hit a Russian logistics and equipment depot near Kalanchak in occupied Kherson Oblast.

The General Staff said these strikes disrupt Russian logistics and reduce the military’s ability to accumulate and use ammunition, equipment, and personnel.

Strike reported inside Russia

Ukraine also reported striking a Russian personnel concentration area near Butyrky in Russia’s Belgorod Oblast.

The General Staff did not provide details on the weapons used, the scale of damage, or possible casualties at the individual sites.

The latest report is part of Ukraine’s continued campaign to strike Russian military infrastructure beyond the battlefield. The “Middle-Strike” concept focuses on targets that support Russia’s ability to conduct and sustain combat operations, including command, logistics, air defense, and other military facilities.

The General Staff said Ukrainian forces continue to carry out strikes against key Russian military targets.

A man was killed in an explosion in occupied Sevastopol on the morning of 13 August, according to the Russian outlet ASTRA and the local Telegram channel Emergency/Sevastopol.

The man's identity has not been officially confirmed, but Russian and Ukrainian Telegram channels are circulating claims that he is Robert Shahieiev, deputy commander of the 4th separate submarine brigade of Russia's Black Sea Fleet — a former Ukrainian Navy officer who sided with Russia after the occupation of Crimea.

What happened

According to preliminary information from Russian sources, the man was walking down a set of stairs with a friend when the explosion occurred. He died of his injuries at the scene. The device is believed to have been planted in a trash bin next to a bench, per preliminary reports cited by Ukrainska Pravda.

The Russian Telegram channel "Baza" reported that the blast took place in a park behind a residential block on Stoletovsky Avenue and that forensic investigators were working at the scene. The channel said local residents were being urged to stay alert and avoid approaching suspicious objects.

Some witnesses initially believed a drone had struck a nearby building because of how loud the blast was, according to accounts circulating on Telegram.

Unverified claim about a suspect

The pro-Kremlin channel Mash claimed a woman carrying a backpack may have been involved, alleging she stood between two residential buildings — numbers 28 and 30 — and watched the man before the explosion. Ukrainska Pravda noted this claim has not been confirmed.

No source has provided official confirmation of the victim's identity or a motive for the attack.

A large-scale Ukrainian drone attack cut electricity across occupied Sevastopol overnight on 13 August, with power later restored on a temporary scheme after strikes damaged the city's energy infrastructure, the Russian-installed head of the city wrote on his Telegram channel.

The blackout is the latest blow in Ukraine's months-long campaign to isolate occupied Crimea by degrading the fuel, power, and transport networks Russia relies on to hold the peninsula. Sevastopol — the former main base of Russia's Black Sea Fleet — has lost power repeatedly since early June, when Ukraine sharply escalated strikes on Crimean energy sites.

What was hit

Drones headed toward the Balaklava thermal power plant, one of the peninsula's two main power stations, while mobile fire groups worked over Sevastopol, the monitoring channel Crimean Wind reported. Witnesses described an explosion and the loss of electricity across the city.

A fire also broke out at a large water-supply facility near the village of Shturmove, south of Sevastopol, around the time of the strike on Balaklava, the same channel said. The cause has not been established. The site houses the city's No. 3 hydro unit, which supplies Sevastopol's water.

Elsewhere on the peninsula, gunfire was reported near the Tavriiska thermal power plant, and Russian air defense operated near the Gvardiiske airfield.

A grid already rationing power

Russia closed the Crimean Bridge to road traffic during the attack, the crossing's occupation-run information channel reported.

The outage lands on a grid already under strain. Sevastopol last went fully dark on 27 July, and in July the occupation authorities imposed a rolling blackout schedule that left residents with about six hours of electricity a day. Since early June, Ukrainian strikes have repeatedly cut power across Crimea, with some districts dark for a week or more, alongside disruptions to water and mobile coverage.

The isolation campaign

Ukrainian officials have described the strikes as stages of a plan to cut occupied Crimea off from mainland Russia. Beyond power plants, Ukraine has hit the fuel tankers supplying the peninsula, the bridges and rail links feeding it, and Russian vessels — leaving Crimea rationing petrol and, at times, short of food.

Ukraine's military had not publicly claimed the 13 August strike as of publication.
