Ukrainian forces reportedly conducted successful drone strikes against Russian military infrastructure and oil refineries in occupied Crimea, Krasnodar Krai, and Leningrad Oblast on the night of May 18 to 19. The Russian Ministry of Defense (MoD) claimed that Russian forces destroyed nine ATACMS missiles over occupied Crimea. A prominent Kremlin-affiliated Russian milblogger claimed that Ukrainian forces launched 12 ATACMS against Sevastopol Bay — nine of which Russian forces shot down near Sevastopol and Belbek airfield, and three of which struck a vessel in Sevastopol port. Footage published on May 19 purportedly shows Russian forces attempting to repel Ukrainian drones over the port in Novorossiysk, Krasnodar Krai. Krasnodar Krai Governor Venyamin Kondratyev claimed that Russian air defense suppressed over 10 drones near Novorossiysk and that falling debris caused fires. Sources in Ukrainian intelligence told Ukrainian outlet Suspilne that Ukraine's Security Service (SBU) and Unmanned Systems Forces conducted successful drone strikes against the Slavyansk oil refinery in Slavyansk-on-Kuban, Krasnodar Krai and against the Kushchyovskaya airfield in Krasnodar Krai where Russian forces station Su-34, Su-25, Su-27, and MiG-29 aircraft used to conduct strikes in Ukraine. The sources stated that the Ukrainian drone strikes damaged several aircraft at the Kushchyovskaya airfield and several distillation columns at the Slavyansk oil refinery. Slavyanskiy Raion Head Roman Sinyagovsky claimed that six drones fell on the Slavyansk oil refinery, and Krasnodar Krai Operational Headquarters reported that Russian air defense suppressed at least 10 drones over Slavyanskiy and Kushchyovskiy raions. Ukrainian forces previously conducted successful drone strikes against the Kushchyovskaya airfield in April 2024 and the Slavyansk oil refinery in March and April 2024. The Ukrainian General Staff reported that Ukrainian forces also destroyed the Russian Black Sea Fleet's (BSF) Kovrovets Natya-class minesweeper, although it is unclear if Ukrainian forces destroyed the minesweeper near occupied Sevastopol, Crimea, or Novorossiysk, Krasnodar Krai as the BSF has redeployed the majority of its naval assets to Novorossiysk over the past year. Suspilne also reported on May 19 that its sources within Ukrainian special services stated that Ukraine's Main Military Intelligence Directorate (GUR) caused explosions at an unspecified number of vertical fuel tanks at the Vyborg oil depot in Leningrad Oblast with three explosive devices. Geolocated footage published on May 18 shows a large fire at the oil depot, although Leningrad Oblast Governor Alexander Drozdenko denied reports that drone strikes caused the explosions and claimed that pyrotechnics caused the explosions near the oil depot.

Key Takeaways:

• Ukrainian forces reportedly conducted successful drone strikes against Russian military infrastructure and oil refineries in occupied Crimea, Krasnodar Krai, and Leningrad Oblast on the night of May 18 to 19.

• Russian milbloggers appear to be experimenting with different ways to express critical opinions of the Russian Ministry of Defense (MoD) following the recent appointment of Russian Defense Minister Andrei Belousov.

• Russian Security Council Deputy Chairperson Dmitry Medvedev threatened Russian internet technology and telecommunications company Yandex because its large language model failed to provide responses that cohere with ongoing Russian information operations.

• A St. Petersburg court ruled that Russian authorities can seize over 700 million euros ($760 million) of assets from three large European banks on May 18 on behalf of a Gazprom subsidiary.



• Russian forces recently marginally advanced within Vovchansk and near Chasiv Yar and Donetsk City.
