Nine hundred and forty-eight drones. One day.

Russia has launched the largest aerial attack of its four-year war against Ukraine, deploying 948 drones across a 24-hour period that stretched from Monday night through Tuesday afternoon. The barrage killed at least five people, injured dozens more, and reached deep into western Ukraine — far from the entrenched front lines in the east.

The scale is unprecedented. More than 400 drones struck during daylight hours alone on Tuesday, an unusual tactic for Russian forces, which typically favor night attacks when air defenses are harder to coordinate. Ukrainian Air Force spokesman Yurii Ihnat said the drones entered Ukrainian airspace from the north, “effectively moving in columns.”

The message is unambiguous: Russia’s spring offensive has begun.

A Shift in Targets

Western Ukraine has been hit far less frequently than regions near the Russian border. Tuesday’s attacks changed that calculus.

Lviv, a city near the Polish border that has served as a logistical hub for Western aid, saw 22 people injured and a residential building set ablaze. The Bernardine monastery, a 16th-century UNESCO heritage site, sustained damage. In Ivano-Frankivsk, two people were killed and four injured — including a six-year-old child. A maternity hospital was damaged. Vinnytsia reported one death and 11 injuries.

The geographic spread signals a deliberate strategy: overwhelm Ukraine’s air defense network by forcing it to protect the entire country simultaneously.

What Four Years of War Have Wrought

Russia’s capacity to sustain this level of firepower after four years of grinding warfare is the strategic revelation of this attack. The 948 drones were accompanied by 23 cruise missiles and seven ballistic missiles, according to Ukrainian officials. Moscow has not exhausted its arsenal.

Ukraine’s air defenses, heavily reliant on Western-supplied systems, face an impossible math problem. Shooting down nearly 1,000 drones requires interceptors, ammunition, and coordination across multiple time zones. Each successful interception depletes stockpiles that take months to replenish.

On the ground, Russian forces have intensified assaults along the roughly 1,250-kilometer front line snaking through eastern and southern Ukraine. Ukrainian defenders, stretched thin and awaiting a spring mobilization that may never fully materialize, are bracing for what could be a decisive push.

The Diplomatic Vacuum

The timing is not coincidental. US-brokered peace talks have stalled since the outbreak of the Iran war on February 28, which diverted Washington’s attention and resources to the Middle East. Ukrainian President Volodymyr Zelenskyy acknowledged this week that the “geopolitical situation has become more complicated” and that the Iran conflict “bolsters Russia’s confidence.”

According to Ukrainian media reports, US officials have increased pressure on Kyiv to consider withdrawing from the Donetsk region as part of a potential settlement. Washington has also warned that it may step back from mediation efforts entirely if no progress is achieved.

Russia, sensing advantage, has rejected ceasefire proposals and refused direct leadership-level talks. Instead, Moscow is supporting the Iranian regime with intelligence data while preparing, in Zelenskyy’s words, for “new conflicts in the coming years.”

What’s at Stake

The spring offensive will test whether Ukraine can hold territory it has defended since 2022. Russia’s larger army, now reinforced and resupplied, is probing for weaknesses along a front that has remained largely static for over a year.

For European security, the implications are stark. If Moscow makes significant territorial gains while Western attention remains divided, the calculus of deterrence across the continent shifts. The 948 drones are not just an attack on Ukraine — they are a demonstration of what a determined adversary can achieve when its opponents are distracted and its neighbor’s defenses are stretched thin.

The war, now entering its fifth year, shows no sign of ending. Russia has just made clear it has the capacity to escalate.
