US intelligence officials have warned that Russia is building a drone-manufacturing facility  with Iran’s help that could have a significant impact on the war in Ukraine and terrorizing Ukrainians once it is completed.

When the facility is completed, likely by early next year, the new drones could have a significant impact on the conflict, the analysts warned. In April, the US released a satellite image of the planned location of the purported drone manufacturing plant, inside Russia’s Alabuga Special Economic Zone about 600 miles east of Moscow. The analysts said Iran has regularly been ferrying equipment to Russia to help with the facility’s construction.

They added that to date, it is believed that Iran has provided Russia with over 400 Shahed 131, 136 and Mohajer drones.

Russia is primarily using the drones to attack critical Ukrainian infrastructure and stretch Ukraine’s air defenses, a senior DIA official said. Iran has been using the Caspian Sea to move drones, bullets and mortar shells to Russia, often using vessels that are “dark,” or have turned off their tracking data to disguise their movements, CNN has reported.

One of the drones recovered in Ukraine had only its wings and engine partially intact. But judging by its shape and size, it appeared to be a Shahed-131, the same model as an Iranian-made drone found in Iraq.
