Russian forces conducted the largest single drone strike of the war against Ukraine on the night of May 17 to 18 – in disregard of US President Donald Trump's calls for Russia to stop long-range strikes against Ukraine, particularly against Kyiv Oblast. The Ukrainian Air Force reported that Russian forces launched 273 Shahed and decoy drones from the directions of Bryansk, Kursk, and Oryol cities; Millerovo, Rostov Oblast; and Primorsko-Akhtarsk, Krasnodar Krai. The Ukrainian Air Force reported that Ukrainian forces shot down 88 drones over eastern, northern, and central Ukraine; that 128 decoy drones were "lost in location;" and that one drone was still in Ukrainian airspace as of 0800 local time. Ukrainian officials reported that the Russian strike largely targeted Kyiv Oblast and that drones struck Kyiv, Dnipropetrovsk, and Donetsk oblasts. Russian forces launched 267 drones (and three ballistic missiles) in their overnight strike series against Ukraine on the night of February 22 and 23. Russian forces have significantly intensified their nightly strikes against Ukraine over the last five months and have conducted several of the largest strikes of the entire war since January 2025. A Russian milblogger claimed that the May 17-18 record-breaking strike was effective due to Russia's use of the "Geran-3" drone (the Russian analogue to the Iranian Shahed-238), which is reportedly equipped with a turbo jet and 300-kilogram warhead. ISW continues to assess that Russian forces are innovating their long-range drone strike tactics in order to offset the effectiveness of Ukrainian mobile defense units and overwhelm the Ukrainian air defense umbrella.
The Kremlin continues efforts to project Russia's military strength ahead of US President Donald Trump’s scheduled phone call with Putin on May 19. Kremlin journalist Pavel Zarubin published on May 18 excerpts of an allegedly "new" interview with Putin, in which Putin claimed that Russia has enough manpower and materiel to bring the war in Ukraine to its "logical" conclusion with the "necessary" results for Russia. Putin reiterated long-standing Kremlin narratives about the necessity that peace negotiations address the war’s "root causes" and "protect" of Russian-speakers of Ukraine, whom Putin claimed consider Russia their "motherland." Ukrainian outlet The Kyiv Independent and Russian state media reported on May 18 that the excerpts that Zarubin published on May 18 are unaired footage from the documentary "Russia.Kremlin.Putin.25 Years" that the Kremlin published on May 4 in which Putin repeatedly promoted claims about Russia’s ability to bring the war to its "logical conclusion." The Kremlin's decision to delay publishing these clips until May 18 suggests that the Kremlin is trying to project a strong, militarily superior Russia to the West and to domestic Russian audiences ahead of Putin’s May 19 phone call with Trump. Russian Presidential Aide Vladimir Medinsky recently stated that Russia is prepared to fight for "however long it takes," and Russian Security Council Secretary Dmitry Medvedev recently made thinly veiled nuclear threats in reference to what Medvedev categorized as "negotiating ultimatums."
