A June 3 Ukrainian strike hit the Petersburg Oil Terminal and reportedly damaged the Baltic Fleet corvette Boikiy near Kronstadt, extending Kyiv’s long-range campaign against Russian energy and naval assets.
More than 1,000 kilometers from Ukraine, the attack underscored the reach of Kyiv’s new strike capability and targeted infrastructure that helps turn Russian oil exports into wartime revenue.
The corvette was used to escort Russia’s shadow tanker fleet, linking the operation to Ukraine’s broader effort to disrupt sanctions evasion as well as military logistics.
That pressure comes as higher oil prices—after the Iran war briefly pushed Brent above $100 a barrel—have offered Moscow fiscal relief, making export-terminal strikes more important to limiting the Kremlin’s windfall.
Can Ukraine's strikes on oil infrastructure cripple Russia's economy faster than high global prices can rescue it?
With new long-range missiles, are Ukraine and Europe building a security shield independent of American political shifts?
As Russia's military falters, could a US-brokered peace deal snatch diplomatic victory from the jaws of its defeat?
