United States forces have carried out a covert maritime operation in the Indian Ocean, intercepting and boarding a commercial vessel transporting suspected military-related cargo from China to Iran, according to reports by the Wall Street Journal and confirmed by U.S. officials.
The operation, which took place in November 2025, occurred hundreds of miles off the coast of Sri Lanka, a key corridor along one of the world’s busiest shipping routes. U.S. special operations forces reportedly boarded the ship at sea after intelligence indicated it was carrying prohibited materials destined for Iran’s weapons programs .
According to the reports, U.S. personnel searched the vessel and seized components believed to be linked to Iran’s conventional weapons and missile development, including items described as dual-use materials—equipment that can be used for both civilian and military purposes. U.S. officials said the confiscated cargo was destroyed to prevent it from reaching Iran .
After the seizure, the ship was allowed to continue its journey, and no arrests were publicly disclosed. Authorities have also declined to release the vessel’s name, ownership details, or the exact nature of the seized materials, citing operational and intelligence sensitivities .
The raid is considered highly unusual, as direct interdictions on the high seas are rare and typically conducted only when there is strong intelligence of sanctions violations or weapons proliferation. Analysts say the move underscores Washington’s determination to block supply chains supporting Iran’s military capabilities, particularly amid heightened tensions over Tehran’s missile program and regional activities.
The incident also adds to growing scrutiny of China–Iran trade links, especially involving sensitive technology and materials restricted under U.S. and allied sanctions regimes. While neither Beijing nor Tehran has officially responded to the report, past cases have seen both countries deny wrongdoing and accuse Washington of overreach.
Security experts note that the operation reflects a broader U.S. strategy of maritime enforcement and targeted interdictions, complementing sanctions and diplomatic pressure aimed at curbing Iran’s access to weapons-related technology and resources.
The U.S. military has not indicated whether similar operations are planned, but officials say intelligence-driven actions will continue where there is evidence of illicit arms transfers threatening regional and global security .
