RAN has shown Russia US drones it shot down over the Gulf, Revolutionary Guards aerospace commander Brigadier General Amir Ali Hadjizadeh was quoted as saying.
"Russian experts requested to see these drones and they looked at both the downed drones and the models made by the Guards through reverse engineering," the official IRNA news agency quoted Hadjizadeh as saying.
Hajizadeh did not elaborate on the number or type of unmanned US aircraft it had shot down, or when or where it had done so.
Iran announced on January 2 that its forces had downed two US drones after they "violated" Iranian-controlled territory.
It later said it would put the aircraft on public display.
"The planes that were shot down are among the most modern US navy drones and have a long-range capability," the Fars news agency quoted the commander of the Guards' naval forces, Ali Fadavi, as saying at the time.
