Ukrainian Unmanned Systems Forces, led by commander Robert “Magyar” Brovdi, destroyed two Russian Tu-142 naval reconnaissance aircraft and an Iskander ballistic missile system during an overnight strike on May 30. The operation, conducted by the 1st Center of the Unmanned Systems Forces, targeted a military airfield in Taganrog, a port city in Russia's Rostov Oblast. Rostov Governor Yuri Slusar reported that the drone attack also ignited fuel tanks and an oil tanker, causing two civilian injuries.
The strike is part of a broader, synchronized campaign to degrade Russian logistics in the "deep rear." The 412th Nemesis Brigade, a decorated drone unit, announced it has joined the Unmanned Systems Forces in a "massive hunt" for military assets, utilizing new fixed-wing drone platforms developed for deep-strike missions. This campaign has forced Russian authorities to shut down the Manhush-Berdiansk highway, a critical land corridor connecting occupied Crimea to the Donetsk region. Residents in Mariupol report that traffic is being diverted through the coastal village of Urzuf, where large columns of trucks are now stalled and entry is restricted to those with local residency permits.
Energy infrastructure across Russia also faced sustained pressure throughout the weekend. Ukrainian forces confirmed strikes on the Saratov oil refinery and the Lazarevo oil-pumping station in the Kirov region, located approximately 1,300 kilometers from the Ukrainian border. While Russian officials acknowledged damage to "civil infrastructure" in these regions, Moscow-backed authorities in occupied Crimea introduced restrictions on petrol sales, a move linked to the ongoing targeting of fuel logistics in the south.
Controversy emerged regarding the Zaporizhzhia nuclear power plant, where Russian officials alleged a drone strike hit the turbine hall of the facility's sixth unit. Rosatom director Alexéi Lijachov claimed the strike was “deliberate,” though Ukrainian forces denied the accusation, labeling it propaganda. International Atomic Energy Agency (IAEA) Director General Rafael Grossi expressed concern over the incident, stating that "attacking nuclear facilities is like playing with fire," and requested immediate access for agency experts to inspect the site.
These tactical developments occur as the Kremlin faces an mounting financial crisis. A letter from Finance Minister Anton Siluanov, reviewed by the Financial Times, indicates that Russia’s war spending is projected to exceed the 2026 budget by at least 2 trillion rubles ($28 billion). The federal budget deficit reached 5.9 trillion rubles in the first four months of the year, the largest shortfall since the 2022 invasion. To compensate, Siluanov has requested the suspension of 2.9 trillion rubles in planned non-military spending for 2026, with further cuts proposed for 2027 and 2028.
Despite a revenue boost from high oil prices, the Finance Ministry warned that energy windfalls are insufficient to cover the escalating costs of the conflict. In response to the ongoing threat, President Volodymyr Zelenskyy confirmed the arrival of a new German-supplied Iris-T air defense system. Zelenskyy emphasized the continued need for international support, stating, “We also need missiles for air defence systems to have sufficient capabilities to repel Russian attacks.”
