On June 3, 2026, Ukraine’s Unmanned Systems Forces targeted the RFS Boykiy, a 2,200-ton Steregushchiy-class corvette in maintenance at Kronstadt’s Veleshchynskyi Dry Dock. The 414th Brigade, called ‘Magyar’s Birds,’ released footage showing the strike at 06:35 local time, igniting a fire that damaged the superstructure, radar arrays, and main mast.
This first confirmed hit on Russia’s Baltic Fleet, over 1,100 km from the front lines, exposed vulnerabilities in a key port during the St. Petersburg International Economic Forum. Russia has not officially commented, with pro-Russian sources downplaying the blaze.
Overnight on June 4, Ukrainian forces hit a Russian Project 10410 Svetlyak-class patrol vessel in the Sea of Azov near occupied Crimea, according to Ukraine’s General Staff. The ship, armed with Igla MANPADS, naval guns, and anti-aircraft autocannons, was part of Russia’s coastal defense. In parallel, drones struck an oil terminal and naval facilities in St. Petersburg’s Kronstadt base, destroying one storage tank, damaging six others, and igniting multiple large fires.
Ukraine’s drone program has evolved from small commercial quadcopters in the early war period to an industrial-scale operation producing between 1.2 and 1.8 million drones annually, with potential to reach 20 million. President Zelenskyy says over 80% of successful strikes now rely on drones, replacing artillery and costly Western missiles. The diverse fleet includes FPV attack, bomber, kamikaze, interceptor, long-range strike, and naval drones, enabling hits on targets thousands of kilometers away.
Maj. Gen. Volodymyr Havrylov noted that Russia has lost numerous air-defense systems and has pulled some back to defend critical infrastructure from deep strikes. He said Russian forces are now making interceptor drones to counter Ukrainian unmanned systems and could introduce them within months. He emphasized the need for Ukraine to develop countermeasures during this period to maintain its advantage.
Ukraine’s ability to hit critical infrastructure deep inside Russia could force Moscow to divert resources from frontline operations to homeland defense, potentially slowing its offensives. In one plausible future, sustained deep strikes erode Russian logistical capacity, enabling Ukrainian counteroffensives. Alternatively, rapid Russian deployment of interceptor drones could blunt Ukraine’s reach, leading to a contested drone battlefield and renewed emphasis on traditional strike assets.
