LONDON — December saw a new record number of Ukrainian long-range drones shot down by Russian forces, according to statistics published by the Russian Defense Ministry and analyzed by ABC News, with Moscow claiming to have destroyed more than 4,300 over the course of the month.

Through December, Russia’s Defense Ministry claimed to have shot down 4,379 Ukrainian long-range drones, at a rate of around 141 each day.

ABC News cannot independently verify the data released by either Russia or Ukraine. It is possible that both sides may seek to exaggerate the effectiveness of their air defenses, or to amplify the attacks against them as proof that their enemies are not interested in pursuing a peace deal.

The total number of Ukrainian drones being reported as shot down by Moscow is still significantly less than the number of munitions launched into Ukraine by Russian forces, as detailed in the daily after-action reports from the Ukrainian air force.

But the gap between the two figures appeared to have narrowed in December compared to recent months, according to data released by both sides and analyzed by ABC News.

In December, Ukraine’s air force said Russia launched a total of 5,307 long-range munitions — 5,131 drones and 176 missiles. Of the drones, nearly 81% were shot down or suppressed, while around 64% of missiles were also defeated, the air force said.

The scale of Russia’s attacks on Ukraine through December were similar to previous months, all of which were slightly down on the record-breaking month of July.

Over the course of July, Ukraine’s air force said Russia launched 6,443 munitions — 6,245 drones and 198 missiles — into the country.

This year has seen an exponential increase in the scale of long-range cross-border strikes by both Russia and Ukraine, according to data released by each side, as the combatants try to destabilize their opponent’s economy and sap their ability to marshal military and financial resources to fight the ongoing war.

Neither side provides detailed data on the scale of their own attacks or their targets, though often release statements describing the targets as military, energy or industrial sites. Both sides accuse the other of intentionally attacking civilian targets.

Both Kyiv and Moscow do offer limited information on their day-to-day air defensive actions.

Ukraine’s air force publishes what it says is a daily tally of Russian drone and missile strikes, including information as to how many munitions were intercepted and how many hit targets. Russia’s Defense Ministry only publishes figures of Ukrainian drones it claims were shot down.

The last month of the year saw the reported number of Ukrainian drones surpass even the most intense months of 2025, which has seen the largest barrages of the war, according to data published by both Ukraine and Russia.

The days on which Russia reported the highest number of drones shot down this year were on Dec. 24, when 387 drones were reported destroyed, and on Dec. 11, when 336 drones were recorded as having been intercepted.

Until December, the largest number of Ukrainian drones reported having been downed by Russian forces was in October, when Moscow said it destroyed 3,641 drones at a rate of over 117 per day.

In November, Russia reported downing 3,392 Ukrainian drones at a rate of 113 per day. December saw a 29% increase in reported Ukrainian drones shot down versus November, according to Russian data.

It is unlikely that Russian data offers a full picture of Ukraine’s offensive drone activities. But the numbers appear indicative of Kyiv’s efforts to grow its drone and missile arsenals, the reach of those munitions and the intensity with which it can attack targets inside Russia.

Ukraine’s military confirms the targets of some long-range strikes. When Kyiv does describe the targets, officials say they’re military sites or industrial energy facilities. Over the past year, Ukraine has adopted a special focus on attacking Russian oil refining and transport facilities.

Among the targets claimed struck by Ukraine’s military in December were oil refineries, oil tankers, oil rigs and pipeline infrastructure.

Ukrainian officials have been clear on the value they place on Kyiv’s long-range strike capabilities — and on their intention to further expand their drone and missile arsenals to reach deeper into Russia. To date, the majority of Ukrainian strikes are believed to have been conducted using relatively cheap, Ukrainian-made drones.

“Our production potential for drones and missiles alone will reach $35 billion next year,” Ukrainian President Volodymyr Zelenskyy said in October. “Despite all the difficulties, Ukrainians are creating their national defense product that, in certain parameters, already surpasses many others in the world.”

“Never before in history has Ukrainian defense been so long-range and so felt by Russia,’ Zelenskyy said. “We must make the cost of war absolutely unacceptable for the aggressor — and we will.”

Russian officials have broadly sought to downplay the Ukrainian attacks, with most reports of damage or casualties attributed to falling debris from intercepted drones, rather than craft that found their mark.

But plentiful publicly available information — including video footage and photographs of the attacks — indicate that a significant number of Ukrainian drones do get through Russian air defenses and impact at sensitive military and industrial sites.
