‘Kamikaze’ drones are far cheaper than bigger, more sophisticated Western models, so they can be deployed by the dozens and deliver a big scare factor.
A little before 7am on Monday, people in Kyiv heard a whining sound overhead before identifying where it was coming from – a group of “kamikaze” drones flying into the city.
Drones have been widely used on both sides of the Ukraine conflict, but these were the first Russian attacks that deployed swarms of the aircraft.
Videos and images began to circulate on social media of the drones flying directly over urban infrastructure such as power stations, residential buildings and railways as civilians and soldiers tried to shoot them down with guns.
About 28 were launched on Monday morning in Kyiv. At least four civilians were killed after one of the aircraft hit a residential building.

Tension was high as locals waited to see where the drones would go. There was the low buzz of the aircraft, gunfire and screams as each of the drones still flying found and dove for its target.
The aircraft are called kamikaze drones because they attack once and don’t come back. Ukrainian officials say the ones primarily being used in their airspace are the Iranian-made Shahed-136. About 2,400 were apparently purchased by Russia in August, and their first reported use in Ukraine was a month ago.
They are far from top-end technology. The smallest costs just $20,000 while a traditional drone typically is at least 10 times that figure.
They also carry 35 to 40kg (80 to 90 pounds) of explosives, significantly smaller than most drones. But their value is in their numbers. They appear in large swarms and fly low enough to evade radar-defence systems.
“They’re relatively small, and they’re single use,” said Katherine Lawlor, a research fellow at the Institute for the Study of War. “They fly into something and then explode.”
“It’s important to note that these are not the kinds of drones that you see in other conflicts, such as US Predators, which are far more expensive and sophisticated,” she said. “These drones are effectively missiles – they loiter in place looking for their target.”
Their low price means the drones can be deployed in large numbers, and they hover before they strike, so they have a psychological effect on civilians as they watch and wait for them to strike.

Ukrainian officials estimated they have shot down dozens in the past week and nearly 100 since they were first used. But even if they are shot down, they explode in the air and can spray potentially deadly debris. Those that hit their target detonate on impact.
The emergence of swarms of drones in Ukraine is part of a shift in the nature of the Russian offensive, which some speculate indicates that Moscow may be running low on long-range missiles.
Russia has recently intensified its aerial bombardment of densely populated urban areas, such as the capital, Kyiv.

Analysts say this appears to be in retaliation for recent Ukrainian attacks, such as the bombing of a bridge linking Russia with Russian-occupied Crimea, as well as an attempt to demoralise the Ukrainian population and fighters.
But this strategy also potentially signals a wider trend worldwide.
“These drones allow Russia to target Ukrainians far away from the front line, away from the primary battle space,” says Ulrike Franke, a senior policy fellow at the European Council for Foreign Relations who leads its Technology and European Power Initiative.
“But it’s not just a tactic to target civilian populations and infrastructure. It’s also about depleting Ukrainian air defences,” she said. “Every drone shot down is another shot from Ukrainian defence systems – whether people or weapons – that can’t be used against something else.”
Suicide drones
Like many trends of modern warfare, these techniques appear to have been tested during the decade-long war in Syria, where both Russia and Iran have reportedly used suicide drones.
Unlikely countries are also becoming international drone heavyweights, such as Turkey, which has recently been selling drones to countries such as Somalia, Nigeria and Albania that are locked out of the traditional military marketplaces.
Ukrainian forces themselves have used Turkish-made Bayraktars along with US-supplied Switchblade drones.
