Iranian drones buzz across the Persian Gulf after their pivotal use by Russia in Ukraine

The distinctive buzz of Iranian-designed drones has become a familiar sound in Ukraine over the past four years. Now, it’s increasingly heard across the Persian Gulf as Tehran strikes back with the cheap but effective weapons following the attack by the U.S. and Israel against Iran.

The Shahed drones have made a transformative impact on modern warfare, with Russia sending swarms of the deadly weapons into the skies above Ukraine on nightly missions.

While ballistic and cruise missiles fly much faster and pack a bigger punch, they cost millions and are available only in limited quantities. A Shahed drone costs only tens of thousands of dollars — a tiny fraction of a ballistic missile.

Available in big numbers, the drones have shown their capability to oversaturate air defenses and inflict painful damage at a very low cost.

The debut in Ukraine

After Russia’s botched attempt to capture the Ukrainian capital after its full-scale invasion with tanks, troops and missiles in February 2022, the fighting has turned into a war of attrition that has been increasingly shaped by drones.

While swarms of small drones have played a decisive role on the battlefield, both Russia and Ukraine also have increasingly relied on longer-range drones to attack deep into each other’s territory.

After reaching a deal with Tehran to import Shahed drones early in the war — Shahed means “witness” in Farsi — Russia localized their production. Russian engineers have increased its altitude, made it more jamming-resistant and fitted it with more powerful warheads.

The Russian replica of the Shahed — called “Geran,” or “geranium” — has been put in production at a plant in the Russian province of Tatarstan that has exponentially increased output. Since then, Russia has battered Ukraine with hundreds of drones in a single night – more than were used during some entire months in 2024.

By using large numbers in a single attack, Moscow’s strategists seek to overwhelm Ukrainian air defenses and distract them from engaging more expensive cruise and ballistic missiles that Moscow often uses alongside the drones to hit high-value targets.

And while it flies slow at 180 kph (just over 110 mph), it can range as far as 2,000 kilometers (1,240 miles) and carry a relatively big load of 40 kilograms (88 pounds) of explosives. Ukrainians have dubbed them “mopeds” for their distinctive buzz.

Ukraine has relied on mobile teams armed with machine guns as a low-cost response to the drones to spare using more-expensive Western-supplied air defense missiles. It also has developed interceptor drones and is working to scale up production, but the steady rise in Russian attacks has strained its defenses.

Attacks in the Gulf and beyond

Following the weekend U.S. and Israeli attacks, Iran has struck Israel and also unleashed a barrage of hundreds of missiles and drones on multiple targets in Saudi Arabia, Bahrain, Kuwait, Qatar and the United Arab Emirates.

They included U.S. bases, ports, airports, oil facilities and oil tankers, as well as some high-rise buildings.

Officials in Dubai in the United Arab Emirates said Sunday that air defenses had dealt with 165 ballistic missiles, two cruise missiles and more than 540 Iranian drones over two days. While officials said they intercepted all air attacks Saturday, debris from the knocked-down weapons sparked blazes at some of Dubai’s most iconic locations.

Some Iranian drones flew as far as a U.K. military base in Cyprus. The runway at the Royal Air Force base in Akrotiri was struck by an Iranian drone Sunday, according to U.K. officials, and sirens blared there again Monday when two more drones heading toward the base were intercepted.

State-of-the-art U.S. and Israeli air defense assets have proven efficient in intercepting most of Iran’s ballistic missiles launched at Israel. But the attacks using large numbers of cheap drones hit some softer targets lacking the same level of protection.

Patrick Bury, a professor of security issues at the University of Bath, said drones have transformed warfare, thanks to the combination of “the persistent surveillance and the high-precision strike” coupled with improved targeting systems and artificial intelligence.

He noted the Shahed drones can be easily hidden in the back of a truck.

“What’s taken people by surprise … is the ferocity and the scale with which Iran has retaliated this time,” compared with its response to the June 2025 U.S. and Israeli attacks, Bury told The Associated Press. “What the U.S. and the Israelis are hoping, I think, and calculating, that they can degrade that enough to basically then take some of the steam out.”

Many observers noted the U.S. and its allies could tap the experience that Ukraine gained in dealing with Russian drone attacks.

“Our military must do more ASAP to institutionalize defensive lessons from Ukraine,” said Dara Massicot, a senior fellow at the Carnegie Endowment, posting on X.
