TEHRAN, July 15 — The waters of the Strait of Hormuz have a long memory, and for the families of the mariners who sail them, that history is not abstract. It is written in the hulls of more than 500 vessels damaged during the Iran–Iraq War’s so-called “Tanker War” between 1980 and 1988 — a campaign in which both nations deliberately targeted oil tankers transiting the narrow chokepoint.
What began as a bilateral conflict metastasized into a broader international crisis, drawing in the United States and reshaping the strategic calculus for every nation dependent on Persian Gulf oil.
A chokepoint with centuries of weight
The strategic significance of the Strait of Hormuz has been recognized for centuries, but its modern criticality emerged with the rise of Persian Gulf oil exports. When the Iran–Iraq War turned the waterway into a battlefield, the world took notice. In 1987, the United States launched Operation Earnest Will, a mission to reflag and escort Kuwaiti tankers through the strait.
American warships shepherded commercial vessels under the U.S. flag, a direct intervention that signaled Washington’s commitment to keeping the oil lanes open. For the crews on those tankers, the escort meant a measure of safety — but the threat never fully receded.
Recent flashpoints
The pattern of confrontation did not end with the Iran–Iraq War. In 2019, a series of attacks on tankers near the strait brought the region back to the brink. In May of that year, four vessels were attacked off the coast of Fujairah, a port city on the Gulf of Oman.
The United States and its allies attributed the attacks to Iran. No casualties were reported, but the explosions tore holes in the hulls of the commercial ships, sending a clear signal that the waterway remained volatile.
The following month, tensions escalated further. Iran shot down a U.S. RQ-4A Global Hawk drone near the strait. The high-altitude surveillance aircraft was operating in international airspace, according to the U.S. military.
Iran claimed the drone had violated its airspace. The incident pushed the two countries to the edge of direct military confrontation.
In July 2019, Iranian forces seized the British-flagged tanker Stena Impero in the strait. The vessel was held for two months, its crew detained while diplomatic channels worked to secure its release. For the families of the crew members, those weeks were a waiting game with no clear end.
The seizure underscored the strait’s enduring role as a flashpoint for international conflict — a place where a single incident can escalate into a crisis that holds lives and global markets in the balance.
What to watch next
As of mid-2026, the Strait of Hormuz remains a central node in the world’s energy security architecture. Any new incident — a seizure, a strike, a drone downed — could trigger a rapid escalation. For the mariners who transit these waters, and for the families who wait for them at home, the stakes have never been higher.
