U.S. Navy forces seized a ship flagged to both China and Iran in the Strait of Hormuz on April 20, 2026, claiming it carried chemicals for Iran's ballistic missile program. (centcom.mil) The vessel, identified as MV Sheng Tai, was boarded by U.S. Marines from the USS Bataan after it refused to divert for inspection. A search uncovered 1,200 tons of sodium perchlorate, a key oxidizer used in solid-fuel rocket motors. (navytimes.com) Sodium perchlorate powers the engines of Iran's Shahab-3 and newer Fateh-series missiles by providing oxygen for fuel combustion, much like the booster in a space shuttle launch. The chemical is heavily regulated under UN sanctions against Iran's weapons programs. (armscontrol.org) The Strait of Hormuz, a 21-mile-wide chokepoint between Iran and Oman, handles 20% of global oil shipments, making it a flashpoint for naval interdictions. U.S. Central Command has conducted 15 similar seizures since 2023 under Operation Rough Rider. (cfr.org) This incident follows a fragile U.S.-Iran ceasefire from January 2026, which halted direct strikes after Iran's drone attacks on Gulf shipping. Separate Houthi drone strikes sank two tankers last week, killing 14 crew members. (euronews.com) Iran's Foreign Ministry called the seizure "piracy" and demanded the crew's release, while China protested the boarding of its-flagged vessel. U.S. officials cited intelligence from intercepted communications linking the cargo to IRGC missile factories. (x.com) The UN Security Council imposed sanctions on such missile components in Resolution 2231 after Iran's 2015 nuclear deal, but enforcement relies on naval patrols. Similar seizures in 2024 netted ammonium perchlorate from the same supplier network. (un.org) U.S. lawmakers, including Sen. Lindsey Graham (R-SC), praised the action as deterring "Iran's nuclear escalation," while Rep. Ilhan Omar (D-MN) questioned the evidence and urged diplomacy. The cargo now heads to a U.S. facility in Diego Garcia for analysis. (congress.gov) CENTCOM warns of potential Iranian retaliation, including mine-laying in the Strait, as ceasefire talks in Oman collapsed Sunday. Oil prices spiked 8% to $92 per barrel following the news. (reuters.com)
