Ukraine recaptured a net 100 square kilometers in May 2026 and struck 111 Russian military-industrial, energy, and fuel infrastructure objects with Deep Strike systems. In addition, for the first time, it conducted coordinated multi-target strikes on Moscow and Moscow Oblast under a unified operational plan, Ukraine's Commander-in-Chief General Oleksandr Syrskyi reports.

The Deep Strike operations caused approximately $1.058 billion in economic damage to Russia in May alone, per Syrskyi's estimates.

Ukrainian forces had already liberated more than 400 square kilometers in southern Ukraine since winter and retaken much of Kupiansk in the east, per ISW data and Syrskyi's earlier briefing.

Frontline directions and territorial change

The most intense fighting in May took place along three Ukrainian-defined directions: Pokrovsk, Oleksandrivka, and Huliaipole. The ratio of recaptured to lost territory for the month was approximately over 100 square kilometers in Ukraine's favor, Syrskyi said, with year-to-date recapture exceeding 600 sq km of Ukrainian territory.

The recapture totals are based on Ukrainian General Staff documentation of village-level and small-position retake operations, often conducted by Ukrainian special operations units, drone-supported infantry assaults, and small mechanized actions.

Unmanned systems and the 88,000-target month

Ukraine's Unmanned Systems Forces (SBS) units struck more than 88,000 targets across the front in May, and SBS Command estimates that more than 30,500 Russian military personnel were neutralized by drone strikes during the month, Syrskyi said.

Ukraine's "Front" and "Middle" classes of strike drones continued to systematically destroy Russian command posts and ammunition arsenals. These are the target categories that have become central to Ukraine's broader "logistics lockdown" campaign, funded with $113 million for medium-strike drones against the Russian rear. 

Air defense and naval forces

Ukrainian air defense forces destroyed more than 59,000 aerial targets in May, including kamikaze drones, cruise missiles, ballistic missiles, and reconnaissance UAVs, and repelled 25 combined Russian missile-and-aviation strikes, Syrskyi said.

Ukraine's Naval Forces conducted approximately 1,500 measures during the month to ensure the safety of civilian shipping in the war zone, enabling 633 vessels to transit to and from Ukraine's "Greater Odesa" ports and Danube River ports.
