While Iran purchased trained military dolphins from Russia in 2000, there is no verified evidence they currently operate an active "kamikaze" or weaponized dolphin program. US officials have denied reports that Iran is using mine-carrying dolphins to target vessels in the Strait of Hormuz, calling such claims unfounded.
The Hill +4
Past Activity: Iran acquired 27 military-trained dolphins from the former Soviet Union in 2000, which were originally trained for underwater detection and attacking vessels, notes.
Current Status: Experts believe those dolphins are too old to be operational, and there is no evidence of a modern active program.
The "Kamikaze" Rumors: In May 2026, reports emerged suggesting Iran might use dolphins to carry explosives to attack U.S. ships amidst tensions.
Official Response: U.S. Defense Secretary Pete Hegseth directly denied that Iran has "kamikaze dolphins".
