With Russian ground troops bogged down in a grinding war of attrition, Moscow is striving to press home its advantage in the skies – through an ever-evolving army of drones, courtesy of Iran.

In early January, wreckage of a drone found in Ukraine hinted at a new high-speed model of drone being deployed by Russia in the conflict. It prompted Ukraine President Volodymyr Zelenskyy to air fears over failing to keep pace. “We produce (drones) at about 1,000 a day. We really produce them, but it’s not enough. It’s still not enough,” he told an audience of political business leaders at the World Economic Forum on Jan. 22, 2026.

Ukrainian intelligence suggests that Moscow, too, will also soon be pumping out 1,000 drone units a day, in large part thanks to the support and technical assistance of Iran. A central concern for Ukraine is Russia’s increasing production of long-range attack drones that it has used in mass attacks to strike targets in Ukraine.

Tehran’s role in supplying Russia with hundreds of long-range, kamikaze-style drones is long known. But what has gone largely unnoticed outside Ukraine is Iran’s central role in teaching Russia to produce these drones itself.

As an expert on weapons technology and former assistant director of the CIA for weapons and counterproliferation, I believe use of Iranian technology has helped Russia develop a fleet of sophisticated drones able to erode Ukrainian air defenses and strain the country’s resolve. By doing so, Moscow is able to preserve more expensive missiles for long-range precision strikes.

Both Ukraine and Russia have ramped up drone production since the beginning of the current conflict in February 2022.

Russia was initially unable to produce large numbers of kamikaze drones, and the country’s military seemingly did not at first understand the decisive role........
