Background: On June 3, 2026, Ukrainian drone forces struck the Russian Navy corvette Boykiy in Kronstadt and the St. Petersburg Oil Terminal during the St. Petersburg International Economic Forum. Ukrainian Navy expert Andrii Ryzhenko assessed that the 13-year-old corvette, damaged in dry dock, will be out of service for at least several months, and that the attack demonstrated Ukraine's ability to penetrate Russia's multilayered air defense and strike important military facilities, with psychological impact. Ryzhenko further stated that Ukraine's Security and Defense Forces will analyze the operation to continue weakening Russia's combat capabilities and its ability to escort shadow fleet vessels.

Background: Ukrainian drone units struck a Russian cargo ship loaded with ammunition at Berth No. 3 in the occupied port of Berdiansk on 31 May.

This is the sixth such arrangement negotiated by IAEA Director General Rafael Grossi since late 2025.

Ukrainian Defense Ministry adviser Serhii Beskrestnov analyzed production dates on intercepted Russian munitions, finding that most weapons are fired 'straight from the factory' with minimal reserves. Shahed drones are 5-15 days old, Zircon and Kh-101 missiles are from 2026. The Iskander 9M723 ballistic missile is an exception, with 2025 production dates suggesting a stockpile of 180-250 missiles, representing three to four months of inventory at current production rates. This stockpile is particularly dangerous due to the Patriot interceptor shortage.

Russian forces struck a logistics facility in the Odesa region with two ballistic missiles carrying cluster warheads, wounding eight road workers, two seriously.
