WASHINGTON — The Biden administration has embarked on a broad effort to halt Iran’s ability to produce and deliver drones to Russia for use in the war in Ukraine, an endeavor that has echoes of its yearslong program to cut off Tehran’s access to nuclear technology.
In interviews in the United States, Europe and the Middle East, a range of intelligence, military and national security officials have described an expanding U.S. program that aims to choke off Iran’s ability to manufacture the drones, make it harder for the Russians to launch the unmanned “kamikaze” aircraft and — if all else fails — to provide the Ukrainians with the defenses necessary to shoot them out of the sky.
The breadth of the effort has become clearer in recent weeks. The administration has accelerated its moves to deprive Iran of the Western-made components needed to manufacture the drones being sold to Russia after it became apparent from examining the wreckage of intercepted drones that they are stuffed with made-in-America technology.
U.S. forces are helping Ukraine’s military to target the sites where the drones are being prepared for launch — a difficult task because the Russians are moving the launch sites around, from soccer fields to parking lots. And the Americans are rushing in new technologies designed to give early warning of approaching drone swarms, to improve Ukraine’s chances of bringing them down, with everything from gunfire to missiles.
But all three approaches have run into deep challenges, and the drive to cut off critical parts for the drones is already proving as difficult as the decades-old drive to deprive Iran of the components needed to build the delicate centrifuges it uses to enrich near-bomb-grade uranium. The Iranians, American intelligence officials have said in recent weeks, are applying to the drone program their expertise about how to spread nuclear centrifuge manufacturing around the country and to find “dual use” technologies on the black market to sidestep export controls.
In fact, one of the Iranian companies named by Britain, France and Germany as a key manufacturer of one of the two types of drones being bought by the Russians, Qods Aviation, has appeared for years on the United Nations’ lists of suppliers to Iran’s nuclear and missile programs. The company, which is owned by Iran’s military, has expanded its line of drones despite waves of sanctions.
The administration’s scramble to deal with the Iranian-supplied drones comes at a significant moment in the war, just as Ukraine is using its own drones to strike deep into Russia, including an attack this week on a base housing some of the country’s strategic bombers. And it comes as officials in Washington and London warn that Iran may be about to provide Russia with missiles, helping alleviate Moscow’s acute shortage.
Officials across the Western alliance say they are convinced that Iran and Russia, both isolated by American-led sanctions, are building a new alliance of convenience. One senior military official said that partnership had deepened quickly, after Iran’s agreement to supply drones to the Russians last summer “bailed Putin out.”
