Drones Over Donbas: How Unmanned Aircraft Changed the War in Ukraine
KYIV, Ukraine – In the predawn darkness of June 1, 2025, a mysterious whirring sound cut through the air at a Russian airfield deep in Siberia. Moments later, small explosive-laden drones burst from the roofs of wooden sheds on the back of trucks and streaked toward rows of parked warplanes. Russian guards barely had time to react. A series of fireballs rolled into the sky as several Tu-95 and Tu-22 strategic bombers erupted in flames. By dawn, more than 40 Russian aircraft lay damaged or destroyed in what appeared to be Ukraine’s most audacious drone strike of the war. The operation – code-named “Spider’s Web” – had been in the works for months under top-secret oversight by Ukrainian intelligence and President Volodymyr Zelensky. It marked a dramatic escalation in a conflict that has increasingly been defined by the hum of propellers and the glow of drones’ night-vision cameras rather than the rumble of tank columns.
The Rise of Drone Warfare in Ukraine
Such scenes would have seemed like science fiction just a few years ago. Yet the war in Ukraine has become the first major conflict where drones are playing a truly vital role, with some experts comparing their impact to that of the machine gun in World War I. In the early weeks of the 2022 invasion, one drone in particular grabbed headlines: the Turkish-made Bayraktar TB2. This medium-altitude, armed drone gave Ukraine a precision-strike capability it had never had before. Videos showed the Bayraktar TB2 hunting Russian armored convoys from above – knocking out tanks, artillery pieces, and even naval vessels with startling efficiency. According to one open-source analysis, Ukrainian TB2 strikes in the first months of the war destroyed at least five tanks, multiple rocket launchers, and several air-defense systems, among other targets. Ukrainians even composed a hit song praising the “holy Bayraktar,” reflecting how this drone became a symbol of resistance. However, as Russia’s air defenses adapted, the lumbering TB2’s once-vaunted prowess waned. By late 2023 Ukrainian officials admitted the big drone had become difficult to deploy without being shot down, and its sorties grew much rarer.
If the Bayraktar’s star has faded, it’s only because a new generation of drones has risen to take its place. In this war, smaller and cheaper unmanned aircraft – some no bigger than a shoebox – have proven to be game-changers. Quadcopters and first-person-view (FPV) racing drones, originally sold for filming weddings or high-speed drone races, are being retrofitted with explosives and turned into miniature cruise missiles. Remarkably, the total cost of parts for a weaponized FPV drone can be as little as $500. Despite their toy-like appearance, these tiny machines pack a deadly punch. Every day, battlefield videos show $500 drones zipping over trenches and destroying artillery pieces or tanks worth millions of dollars – a staggering cost disparity that is reshaping military economics. “Ukraine’s tactical drones are inflicting roughly two-thirds of Russian losses,” says a recent study by a British defense think tank, making them “twice as effective as every other weapon in the Ukrainian arsenal”. In short, what began as an improvisation – soldiers buying hobby drones online and crowd-funding “dronations” from civilians – has evolved into a central feature of modern warfare.
Eyes in the Sky: Reconnaissance and Precision Strikes
One of the most crucial roles of drones in Ukraine is reconnaissance – giving soldiers eyes in the sky. Small commercial models like the ubiquitous DJI Mavic quadcopter have become the wartime workhorses for both sides. At any given moment over the front lines, dozens of these buzzing cameras hover overhead, spotting enemy movements that once would have been hidden by terrain or darkness. They transmit live video to operators on tablets, peering down into trenches and tree lines with an unblinking stare. This real-time surveillance has made it far easier to detect ambushes or guide troops. It has also drastically shortened the kill-chain – the time between seeing a target and striking it. As soon as a Russian tank is spotted creeping along a tree line, a Ukrainian artillery battery can be dialed in on its coordinates within minutes. In effect, drones have turned even old-fashioned artillery shells into precision-guided munitions. A Ukrainian analyst quipped that drones have made common howitzers into “sniper rifles” for hitting high-value targets from miles away.

Drones are not only hunting targets themselves; they are team players on a modern digital battlefield. Military units now often deploy a pair of drones in tandem: a small recon drone to find the enemy, and a loitering attack drone to finish the job. Ukrainian forces have entire specialized drone units for surveillance, artillery spotting, and bombing missions. In fact, almost every brigade in the Ukrainian army now has its own drone company embedded. Russian units, too, have come to rely on their own drones – models like the Orlan-10 for scouting and the Lancet kamikaze drone for striking Ukrainian armor. The result is a cat-and-mouse aerial duel. Each side stalks the other’s troops with circling quadcopters, while also using electronic jammers to knock drones out of the sky by severing their control signals. The sky above the trenches is alive with this silent duel of robots, each hunting for any sign of the enemy.
Cheap and Deadly: From DIY Drones to Shahed Swarms
Perhaps the most disruptive aspect of drone warfare in Ukraine is how accessible and affordable it is. In past wars, air power belonged only to those who could afford fleets of high-tech jets or expensive missiles. In Ukraine, by contrast, volunteer hobbyists can build a functional attack drone in a garage. Ukraine has rapidly expanded its domestic drone industry – from just a handful of manufacturers to at least 80 drone-making companies within a year. The government has even announced plans to produce a million FPV drones in 2024, treating these tiny aircraft as a new kind of munition to be mass-produced. Such drones can be expended in huge numbers; they don’t need to be reliable or long-lived if they are cheap and deployed en masse. Quantity has a quality all its own. Battlefield reports describe Ukrainian units launching swarms of small drones simultaneously to overwhelm Russian positions or confuse their air defenses. A Russian soldier might shoot down one or two drones, only to be hit by the third or fourth that comes whirring over the trench. “The Taliban had nothing like the swarms of drones sent into the skies by the Ukrainians and the Russians,” one U.S. Army officer observed, contrasting this high-tech threat with past insurgencies.
The R18 octocopter drone, developed by Ukrainian volunteers (Aerorozvidka unit) and seen here at a Kyiv exhibition, is one example of homegrown innovation. Armed with bombs or anti-tank grenades, such multirotor drones give front-line units a cheap way to strike Russian armor from above.
Russia has adapted to this new reality in its own way. Lacking enough domestic high-end drones, Moscow turned to Iran’s workshop of unmanned weapons. Since late 2022, Russia has imported hundreds of Shahed-136 kamikaze drones – cheap, GPS-guided delta-wing drones that can travel over a thousand miles to hit a target. Rebranded as “Geran-2” by the Russian military, these Shaheds have been unleashed in waves against Ukrainian cities and power stations. They fly low and slow, with a distinctive buzzy engine note that has earned them the nickname “mopeds.” Individually, a Shahed carries about 40 kilograms of explosives – enough to cripple a section of power grid or blast a hole in an apartment building. But their real effectiveness comes when they are launched in large salvos. Ukraine’s air defenders have struggled at times to shoot down every drone in a swarm of a dozen or more. Crucially, a Shahed drone is thought to cost as little as $20,000–$50,000 to produce, a fraction of the price of a traditional cruise missile. This means Russia can afford to launch swarms of them nightly, forcing Ukraine to expend expensive air-defense missiles to intercept them. The introduction of these kamikaze drones marked a turning point in the conflict – a new era of low-cost, high-impact warfare where even a country with limited advanced weapons can rain down destruction via remote-controlled planes.

Each Shahed carries a warhead but costs a fraction of a guided missile, exemplifying the new economics of warfare.
Shifting Battlefield Tactics
On the ground, the proliferation of drones has begun to reshape battlefield tactics. Large-scale armored assaults – the thunderous tank-led offensives that once defined warfare – have become exceedingly perilous in the age of drones. Any massing of tanks or troops is quickly spotted by quadcopters orbiting above, and within minutes that formation can be targeted by precise artillery or kamikaze drones. “Drones are making it difficult to concentrate forces, achieve surprise, and conduct offensive operations,” writes Stacie Pettyjohn, a military analyst, noting that Ukrainian and Russian commanders are learning to be more agile and dispersed. In practice, this means units must spread out and stay hidden. Soldiers now camouflage their positions not just from enemy eyes on the ground, but from the infrared gaze of drones in the sky. Command posts that once consisted of clusters of tents and antennae have shrunk to small, clandestine bunkers. “When he flies over, he doesn’t see a large tent complex that looks like a command post,” explained one Ukrainian brigade commander, describing how his HQ is now just “a needle in a stack of needles” – indistinguishable from the terrain to avoid drawing a drone’s attention. During exercises, U.S. officers have taken note of this adaptation. Unlike in past wars where rear bases could be relatively large and secure, in Ukraine even generals in the rear must assume a drone is watching and hunting for any electronic signal that might betray a high-value target.
Trench warfare has also returned, but with a high-tech twist. Infantry on both sides crouch in zig-zagging trenches reminiscent of World War I, yet above them hover quadcopters ready to drop grenades into any foxhole. A simple grenade fitted with fins can be thrown from a drone with uncanny accuracy into the turret hatch of a tank or through the roof of a dugout. As a result, life at the front has been described as “an endless hide-and-seek with drones.” Troops scan the skies constantly; a mere distant buzz sends everyone scrambling for cover under trees or nets. Concentrated tank charges or large infantry assaults have become rarer – and far more costly when they occur – because loitering drones and precise artillery make any frontal attack a deadly proposition. This has contributed to a bloody stalemate in places like the Donbas, where advancing even a few hundred meters can require suppressing countless aerial observers and drone-guided guns. Drones haven’t completely replaced traditional firepower – artillery still causes the majority of destruction – but they have made the battlefield more transparent and lethal than ever before. Even when neither side controls the skies with piloted aircraft, the constant presence of unmanned eyes and munitions means there are no truly safe rear areas.
Logistics, Morale, and the New Face of War
The drone revolution in Ukraine is not only military but also logistical and psychological. On the logistical front, both nations have had to adjust their supply chains to build or acquire thousands of drones and also defend against them. Ukraine, with Western help, set up “drone armies” – training programs and workshops to modify civilian drones for combat use. Its plan to manufacture one million drones underscores a shift in industrial strategy: instead of investing solely in a few heavy weapons like tanks or fighter jets, invest in swarms of expendable flying machines. This approach can be cost-effective. For the price of a single modern main battle tank, Ukraine can likely deploy well over a hundred weaponized quadcopters. Russia’s reliance on Iranian drones, meanwhile, shows how supply lines for war now extend into global tech markets and even hobbyist communities. Electronic components like cameras and radio chips – often the same found in consumer gadgets – have become as crucial as bullets and shells. There is also a race for counter-drone gear: portable jamming guns, radar that can pick up tiny drones, even trained eagles (experimented with by some armies) to snatch drones out of the air. All these must be produced and delivered to the front in large numbers, adding new complexity to wartime logistics.
Morale, too, has been affected by the drone age. For Ukrainian soldiers, the creativity and success of their drone units have been a point of pride – a David vs. Goliath narrative where ingenuity beats brute force. Stories abound of small drone teams stopping armored assaults or destroying expensive hardware with a $500 flying bomb, which boosts the confidence of defenders armed with wit and determination. Ukrainian officials often publicize drone strike footage as proof that high-tech skill is on their side. On the flip side, the psychological pressure on troops under constant drone surveillance is intense. “They can see us everywhere,” is a common refrain. Russian trenches have reportedly been found littered with pamphlets warning soldiers not to even light cigarettes at night, for fear a Ukrainian drone’s thermal camera will spot the glow. Front-line fighters describe the distinct buzzing of an enemy quadcopter overhead as one of the most nerve-wracking sounds in modern war – a herald that death could rain down from above at any moment. Civilians far behind the front have also felt the dread of drones, as buzzing swarms of Shahed kamikaze drones send families running to basements in midnight air-raid alarms. In many ways, drones have become the symbol of ever-present threat in this war, much like tanks were in wars past.
As the war in Ukraine grinds on, it is offering the world a sobering preview of the future of conflict. This conflict has shown that drones – once a niche tool – are now central to modern warfare, from the tactical level up to strategic strikes deep behind enemy lines. We have seen relatively low-cost drones disable billion-dollar warships and bombard distant airbases. We have seen tech-savvy volunteers turn off-the-shelf gadgets into weapons that level the playing field against a larger foe. At the same time, experts caution that drones are not a standalone silver bullet: they work in tandem with traditional arms, and large numbers of drones can be blunted by robust air defenses or electronic jamming. In Ukraine, drones have not replaced the bloody slog of artillery duels and infantry assaults, but they have unquestionably altered the character of the battlefield. Armies around the world are taking note. The war in Ukraine has made one thing clear: from here on, the side with the better drones, and the savvy to use them, will hold a crucial edge. The buzz of a tiny quadcopter over a darkened field may well be the defining sound of 21st-century warfare.
