Ukraine strikes three Russian military-aviation sites in one night, burning the Black Sea Fleet's air headquarters in Sevastopol
Ukraine hit three Russian military-aviation sites in a coordinated overnight operation on 27 May 2026 -- the Baltimor airbase at Voronezh that hosts Su-34 fighter-bombers, the 325th Aircraft Repair Plant at Taganrog, and the Black Sea Fleet's air-force headquarters in occupied Sevastopol, where a missile left the command building badly burned. OSINT monitors and a Russian occupation official attributed at least part of the assault to British-French Storm Shadow cruise missiles, while Moscow's commanders insisted air defences had repelled the attack and blamed "falling debris" for the damage. The strikes extend a deep-strike campaign that has hit Russian refineries, oil terminals and Black Sea Fleet vessels over the preceding week.
Ukraine targeted three facilities tied to Russian military aviation during the night and morning of 27 May 2026: the Baltimor airbase in Voronezh, the 325th Aircraft Repair Plant in Taganrog, and the Black Sea Fleet Air Force headquarters in occupied Sevastopol. Monitoring channels and a Russian occupation official said British-French Storm Shadow cruise missiles were among the weapons used.
A seven-hour air-raid alert sounded over occupied Sevastopol overnight. The missile wave began around 05:02 near the Tavrida thermal power station in Simferopol; explosions started around Cape Fiolent in Sevastopol at 05:07, followed by four powerful blasts with smoke rising over Sevastopol Bay and Sapun Mountain. At about 05:50 a missile struck the Black Sea Fleet Air Force headquarters on Hohol Street. The Crimea-monitoring Telegram channel Krymsky Veter published photographs of the burning building, said it was "badly burned" with no intact windows, and reported that the air headquarters had become the fleet's primary command center after the earlier destruction of the Black Sea Fleet's main headquarters. Mikhail Razvozhayev, the Russian occupation governor, confirmed damage at the Hohol Street site but described the target as "an administrative building that had long been unused" and said four people inside were unhurt. He claimed Russian forces had repelled the combined attack and downed more than 20 Ukrainian drones over the Northern Side, Cape Fiolent, Sevastopol Bay and Omeha Bay. A separate missile hit the Southern Administration of Russia's Central Bank on Lastova Square; Razvozhayev blamed Ukraine, while Krymsky Veter said the building was struck by a Russian Pantsir anti-aircraft missile.
The Baltimor airbase, in Voronezh's Sovetsky district about 200 km from the front, was struck on the morning of 27 May. It hosts the 47th Guards Bomber Aviation Regiment of the 105th Mixed Aviation Division and has been the main staging site for the Su-34 fighter-bombers that have bombed Ukrainian cities since 24 February 2022. Voronezh governor Aleksandr Gusev said air defences destroyed two "high-speed targets" and that falling debris damaged a tire shop and an outbuilding without causing casualties. The Russian OSINT channel Astra geolocated rising smoke to the airbase. The Exilenova+ and AMK Mapping channels assessed that the strike likely used Storm Shadow cruise missiles, citing the short alert duration and Gusev's "high-speed targets" phrasing -- language the outlet Militarnyi noted is consistent with cruise missiles rather than drones.
A fire broke out the same morning at the 325th Aircraft Repair Plant in Taganrog, Rostov Oblast, roughly 170 km from the front line. Rostov governor Yuri Slyusar said air defences shot down a missile over Taganrog and confirmed ground damage from falling debris; the Kyiv Post reported the debris injured two women, one seriously. Astra again geolocated the smoke to the plant's grounds. The 325th is Russia's sole base facility for major overhauls of An-12 and An-72 transports -- aircraft that move munitions and personnel daily -- and also services components for Il-76 heavy transports and the scarce A-50 radar planes. It shares a runway and production capacity with the Beriev TANTK complex, Russia's only maker of A-50 surveillance aircraft, which posted a $65 million loss for 2025. The plant has been sanctioned by the European Union, the United States and Ukraine.
Russia's Defense Ministry said its air defences intercepted 140 Ukrainian drones overnight across seven Russian regions, occupied Crimea and waters of the Sea of Azov and Black Sea, but made no mention of missile strikes. The Tuapse oil refinery on Russia's Black Sea coast was also reportedly targeted again overnight, with Astra publishing eyewitness footage; the extent of the damage was unclear.
The operation extended a deep-strike campaign that over the preceding week hit the Tamanneftegaz oil terminal, the Syzran refinery and Black Sea Fleet vessels including the frigate Admiral Essen. It also came amid a sharp escalation: Russia fired roughly 90 missiles and more than 600 drones at Kyiv between 23 and 24 May, killing four and wounding 87, and on the following Monday announced "systematic strikes" on Ukraine's military-industrial sites and "decision-making centers" in the capital, urging foreign nationals and diplomats to leave. Russian Foreign Minister Sergei Lavrov told US Secretary of State Marco Rubio that Washington should evacuate its Kyiv embassy. Ukraine's foreign minister, Andrii Sybiha, called the warnings "shameless blackmail," and EU Ambassador Katarina Mathernova said Western missions would remain in Kyiv.
