US Central Command said Revolutionary Guard forces launched ballistic missiles toward a US aircraft carrier and a guided-missile destroyer patrolling regional waters; both evaded and no American personnel were injured. In response, US forces permanently disabled the IRGC crude oil carrier M/T Downy off the coast of Kharg Island and the M/T Stark 1 near Jask, and completely destroyed the unladen crude tanker M/T Kylo in the Gulf of Oman after hitting it repeatedly to render it inoperable; its crew was directed to abandon ship. CENTCOM described the vessels as part of a "multibillion-dollar shadow network" funding the IRGC and its regional proxies. Iranian state television said four US missiles struck a tanker about ten kilometres from Kharg Island, and Tasnim reported no casualties.

The provocation matters as much as the response. Danny Citrinowicz of Israel’s Institute for National Security Studies said Iran firing a ballistic missile at a US aircraft carrier "indicates that Tehran is becoming increasingly willing to accept risks it previously sought to avoid", including directly threatening the most important American military assets in the region. Through July and August this archive logged Iranian retaliation aimed at bases hosting US forces in third countries — Jordan, Kuwait, Bahrain, Iraq, the UAE. Firing at a carrier is a different order of target.

The American doctrine was stated plainly. CENTCOM commander Admiral Brad Cooper said that if the IRGC shoots at two US ships, "we will impose an even higher economic cost" by taking out three of Iran’s, adding that Washington would destroy Iran’s limited and exposed oil fleet if necessary. Defense Secretary Hegseth wrote that if Iran shoots at US ships their oil tankers will be destroyed and sunk, and that Iran’s tanker fleet could be hit in the Middle East or the Indo-Pacific because "Iran’s oil tanker fleet is defenseless" — Iran having neither navy nor air force to protect it. This merges the two campaigns this archive has tracked separately: the sanctions programme announced on Day 178 is now being enforced by airstrike.

Audio verified by CNN records how the method worked. A US military aircraft hailed one of the vessels on an emergency channel: "Motor Tanker STARK 1, this is the United States military aircraft. I am preparing to fire at your stern. You have 10 minutes to clear the crew from the stern of your ship." No casualties were reported from any of the three strikes. It is a deliberate distinction from the Kuhestak wedding four days earlier, and the contrast is likely to be made in Tehran as loudly as in Washington.

The two governments do not agree on who moved first. CENTCOM says the strikes on the tankers answered unprovoked Iranian missile fire at its warships. Iranian state media said its navy attacked US destroyers with missiles and drones in retaliation for earlier American action against Iranian tankers, and the state broadcaster later claimed Iran had targeted three oil tankers and three American vessels. Reporting noted the accounts differ substantially and that the precise sequence cannot be independently verified from public information. Iran’s foreign ministry called the US strikes illegal and aggressive, an overt threat to the security of commercial shipping and a clear violation of the UN Charter; its joint military command warned that strikes on US warships would be more severe if Washington keeps interfering with Iranian shipping. Trump, meanwhile, publicly downplayed the war as small potatoes.

Yemen’s internationally recognised government launched its own air attacks on Houthi offensive formations and artillery near Bab el-Mandeb — a shift from the ground defence logged yesterday to an air campaign of its own. Fighting around Hodeidah left 57 casualties recorded, and a missile struck a civilian bus on a crowded road in Taiz, killing 13. In southern Lebanon, Israel claimed control of the Ali al-Taher ridge, a strategic highland position.

Tracker status holds at WAR RESUMED. Day 190 opens a new front that is neither territorial nor conventional: the deliberate destruction of the other side’s export fleet as a stated substitute for striking its soil. Washington has declared Iran’s tankers defenceless and priced retaliation explicitly at three-for-two; Tehran has answered by firing at an aircraft carrier, a target it had avoided for six months. No casualties resulted from any of it, which is the only restraint visible in the day. The strait remains closed, the second chokepoint at Bab el-Mandeb is being fought over on land, and no negotiation exists.
