The war in Ukraine has taken to the skies, and it's not just the birds singing in the sunflowers anymore. As the sun set over a field of tall yellow sunflowers, a moped-like growl disturbed the evening calm. Lt Col Ray, a Ukrainian commander with the 414th aviation brigade, took cover in a leafy ditch as a drone roared into the mauve sky, leaving behind black smoke and a whiff of gunpowder - a modern-day biplane with a wooden propeller, heading for Crimea.
Four and a half years after Vladimir Putin sent tanks to seize Kyiv, the conflict has evolved into an unprecedented battle of drones. "We are making history here. This is where democracy beats totalitarianism. It's like George Orwell. But this time Big Brother loses," Ray said, as the drone vanished over the horizon. Its destination: Crimea, the scenic peninsula stolen by Russia in 2014 and militarised ever since.
On the night of 21 July, Ukraine launched what it calls the Crimean "switch off" campaign - a series of strikes to disconnect the region from power and logistics. That night, 13 electricity nodes were hit, including a 110kV substation in the resort of Alushta, which erupted in flames. The drones, carrying 50-100kg of explosives each, were built in Kyiv by a defence technology startup, and can fly more than 2,500km - far enough to reach anywhere in European Russia and much of Siberia.
Russia has been bombing Ukrainian cities nightly since 2022 with Iranian-designed shaheds and missiles, a campaign of terror that intensified after Donald Trump returned to the White House. Ukraine, once a recipient of Western aid, has responded by becoming the world's leading unmanned systems power. Ray's battalion, named after Kairos, the Greek god of opportunity, has carried out hundreds of deep strikes against oil refineries, warehouses, munitions depots, and logistics routes. In 2026, Ukrainian drones have even struck Moscow and St Petersburg, embarrassing Putin and bringing the war home to ordinary Russians.
"I think Putin is afraid," Ray said. "One of the justifications he gave for his war was to stop Ukraine from bombing Moscow. It's happening now as a direct consequence of his actions." He feels "revenge and justice" with every launch: "We didn't start this war. We have no choice. We are fighting for our independence, for our people, for the memory of those who have died, and for our future."
The operation is shrouded in secrecy. An analytics department finds targets, Western partners provide some intelligence, but most is open source. Crews get coordinates at the last minute, and so far none have been injured or killed. One participant said: "You are making change on a global scale. Trump wakes up and sees the results. At the same time it's very solitary. You can't tell anybody about what you do, even your wife. Only your commander understands."
Kairos is part of "Magyar's Birds", a brigade led by Robert Brovdi, head of Ukraine's unmanned systems forces. In July, Brovdi launched a campaign to destroy oil tankers in the Sea of Azov and Black Sea - more than 200 have been hit. The brigade has also been burning warehouses belonging to Wildberries, Russia's equivalent of Amazon, obliterating at least nine, causing billions of roubles in damage. "The socio-psychological impact on society is greater than that of an oil refinery," Brovdi said.
Brovdi claims Ukrainian drones have "significantly thinned out" Russia's air defences, destroying 305 systems, including recent strikes in the port of Yeysk. "With every air defence unit destroyed, the breach expands." The Kremlin has moved defences from the frontline to protect Moscow, turning Russia's vast size into a weakness. Crimea now has so little fuel that Russian military groups sometimes can't launch drones, and power cuts are frequent.
Brigade member Schweik predicts food shortages: "There will be a cascade effect. They will be thinking about survival instead of assault operations." He added: "The situation is humiliating for Russia. Crimea is symbolic. It was Putin's first trophy and the place where the world order was broken. Now everyone understands that Russia is really weak."
Not all drones reach their targets - about a third are lost over occupied territory, and losses over Russia are higher. But the strategy to pressure the Russian economy appears to be working. "Troops and resources must be exhausted, so that it becomes impossible for them to continue the war," Brovdi said, while acknowledging Russian advances in the Donbas: "Their gains to date do not justify the price they're paying."
Back in the countryside, Ray's colleague "Panama" called the latest launch a success: "It was 10 out of 10." The only challenge is the mosquitoes. "Over time we've become friends with them. They are also inhabitants of free Ukraine. But if they irritate us we will launch them at the enemy. They can eat Russians."
