Iran’s Islamic Revolutionary Guard Corps Navy said it captured a U.S. unmanned underwater vehicle, or UUV, at the entrance to the Strait of Hormuz early local time on Sept. 8, according to Iran’s Tasnim News Agency. The force said the vehicle was taken back into Iran after the operation. The IRGC Navy described the craft as 「one of the world’s most advanced intelligent unmanned submarines」 and said it had been delivered to the U.S. Navy in 2025. It also said the vehicle was seized from what it called 「a complex」 facility. Iranian officials added that photos of the vehicle would be released within hours. The claim had not been confirmed by the U.S. side at the time of publication. The report was cited by BlockBeats in a 7x24 flash update.

According to a report cited by BlockBeats on July 18, China Central Television (CCTV) said information from the Iranian side indicated that a vessel was struck in the Strait of Hormuz that day. A source said the ship was flying the Thai flag and attempted to pass through the waterway despite related warnings. The same source said the vessel had not obtained permission from the naval branch of Iran’s Islamic Revolutionary Guard Corps. It was later intercepted by the IRGC Navy and hit, according to the report. The brief did not provide further details on the vessel, casualties, damage, or the ship’s ownership.
Iran’s Islamic Revolutionary Guard Corps said two foreign oil tankers were attacked and destroyed after, according to its public relations department, the vessels ignored repeated navigation warnings, entered related waters illegally near the Strait of Hormuz, and switched off their navigation systems. The IRGC Navy said it took necessary measures under relevant laws and regulations and handled the two “violating vessels” accordingly. Iran also said the security and uninterrupted passage of the Strait of Hormuz are critical to global energy supply, and that it will continue to safeguard normal traffic through the waterway while responding firmly to illegal acts that threaten regional security. Iranian authorities have started a further investigation into the incident and said more details will be released in due course. The report was cited by BlockBeats from China Central Television.
