Iran is escalating the war by placing explosive mines along a key oil route. Here are the risks.
Iran is escalating the war by placing explosive mines along a key oil route. Here are the risks.
Strategic Control and Mine Deployment
Despite being outgunned and outspent by the US and Israel, Iran retains a strategic edge through its dominance over the Strait of Hormuz. This vital waterway, which carries one-fifth of the world’s oil supply, has become a focal point for Tehran’s efforts to disrupt global energy flows. Recent reports indicate Iran has begun laying mines in the strait, further complicating navigation and signaling a new phase in the conflict.
Types of Mines and Threat Assessment
Iran’s naval arsenal includes around 5,000 to 6,000 mines, according to a US Congress report from last year. These mines vary in design, with some attached to ship hulls by divers, others floating just beneath the surface, and a third type resting on the seabed to detonate upon detecting nearby vessels. The deployment of mines adds a layer of unpredictability to the already perilous passage, potentially creating a chokehold on maritime trade.
“If Iran has put out any mines in the Hormuz Strait, and we have no reports of them doing so, we want them removed, IMMEDIATELY!”
Recent Incidents and US Response
On Tuesday, the Islamic Revolutionary Guard Corps (IRGC) targeted the Thai-flagged bulk carrier Mayuree Naree, igniting an explosion in its engine room. Thai authorities confirmed three crew members were missing, while the Liberian-flagged Express Rome also faced Iranian projectiles in the same morning. Meanwhile, US Central Command claimed to have destroyed 16 Iranian minelayers near the strait, though no mines were explicitly mentioned in the operation.
Earlier, President Donald Trump expressed skepticism about the mine deployment, stating, “we have no reports of them doing so.” His remarks raised questions about the extent of Iran’s actions and the readiness of US forces to counter them. However, the US Navy’s minesweeping capabilities have diminished, with the last dedicated minesweeper decommissioned in September 2025. Critics argue that littoral combat ships now tasked with this role are less reliable, often labeled as “Little Crappy Ships” due to their operational challenges.
Minesweeping Challenges and Economic Risks
The prolonged closure of the Strait of Hormuz has dire economic consequences. Analysts estimate nearly 15 million barrels per day (BPD) of crude oil and 4.5 million BPD of refined products are trapped in the gulf, causing storage facilities to reach capacity rapidly. With the strait effectively blocked, the global economy faces heightened vulnerability to supply chain disruptions.
Iran’s use of asymmetric tactics, including suicide boats and shore-based missile systems, highlights its ability to project power despite conventional disadvantages. The UKMTO, a British security organization, noted, “there remains no confirmed evidence of mine deployment or detonation” in the strait, underscoring the need for ongoing verification amid conflicting reports.
