In a dramatic propaganda broadcast on March 17, 2026, Mojtaba Khamenei, son of the late Supreme Leader Ayatollah Ali Khamenei, unveiled Iran’s latest weapon — a high-speed “underwater missile” claimed to travel at an astonishing 100 meters per second (360 km/h).

Speaking from an undisclosed location, Mojtaba declared the new weapon “a game-changer that will sink American carriers and punish the aggressors.” He boasted that the underwater missile, allegedly unstoppable by current defenses, had already been deployed in the Persian Gulf and Strait of Hormuz. Iranian state media released slick video showing high-speed underwater trails and claimed successful tests against “enemy targets.”

The timing is clearly designed to boost collapsing morale. Iran has suffered devastating losses: the death of Supreme Leader Khamenei, repeated Israeli strikes on Tehran, the destruction of IRGC headquarters, and heavy damage to naval bases.

However, US officials are dismissive.

US Central Command described the announcement as “more Iranian propaganda mixed with exaggeration.” While acknowledging increased underwater drone and torpedo activity in the Gulf, CENTCOM stated that American naval forces have successfully neutralized multiple Iranian underwater threats in recent days. “No new Iranian weapon has changed the battlefield reality,” a senior official said.

America’s naval dominance remains unchallenged.

The dual supercarrier strike group — USS Abraham Lincoln and USS Gerald R. Ford — continues to operate at full combat strength in the Arabian Sea under Operation Epic Fury. Both carriers remain completely undamaged despite weeks of Iranian missile, drone, and swarm boat attacks. Thousands of U.S. Marines, recently deployed by CH-53 Sea Stallion helicopters, have further strengthened coalition capabilities across the region.

Military analysts note that even if Iran has developed a faster underwater system, modern carrier strike groups are protected by multiple layers of advanced anti-submarine warfare, including helicopters, destroyers, and sophisticated sonar networks.

While Iran continues desperate attacks on Gulf cities, shipping, and Israel, its arsenal is visibly shrinking under sustained US-Israeli pressure. Mojtaba’s dramatic reveal appears to be an attempt to project strength at a time when Iran’s conventional military power is being systematically dismantled.

The United States and its allies will not be intimidated by new claims or flashy videos. Superior technology, training, and resolve continue to prevail.

Iran’s underwater gamble, like so many before it, will likely meet the same fate — neutralized by overwhelming American power.
