Iran is escalating the war by placing explosive mines along a key oil route. Here are the risks.
Iran Escalates Conflict by Deploying Explosive Mines in Key Oil Passage
Despite being outmatched in firepower and funding by the US and Israel, Iran retains a critical edge through its dominion over the Strait of Hormuz. This narrow waterway, which facilitates one-fifth of global oil shipments, has become a strategic battleground as Tehran intensifies its operations. Recent reports indicate the country has placed mines in the region, further complicating navigation and signaling a new phase in the ongoing conflict.
US Intelligence and Iranian Naval Strength
According to US intelligence sources, Iran has deployed several dozen mines in the strait, though the scale remains limited. Despite this, Iran still controls over 80% to 90% of its small boats and minelayers, as confirmed by a military official. This contradicts former President Donald Trump’s assertion that Iran “has no navy,” highlighting the nation’s persistent maritime capabilities.
“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!”
Trump’s remarks on Truth Social sparked debate, as US Central Command claimed to have destroyed 16 Iranian minelayers near the strait. However, it did not confirm the elimination of mines, suggesting they may have already been laid. The UKMTO, a British naval intelligence body, noted that there is currently no verified evidence of mine activity or detonations in the waterway.
Types of Mines and Iranian Tactics
The US Congress report estimates Iran holds around 5,000 to 6,000 naval mines, including limpet mines, moored mines, and bottom mines. Limpet mines are manually attached to ship hulls, while moored mines float beneath the surface. Bottom mines lie on the seabed, triggering explosions upon detecting nearby vessels. These diverse mine types underscore Iran’s reliance on asymmetric warfare to disrupt global supply chains.
On Tuesday, Iranian forces intercepted the Thai-flagged bulk carrier Mayuree Naree, resulting in an explosion near the ship’s engine room. Thai authorities reported three crew members missing, with the incident coinciding with an attack on the Liberian-flagged Express Rome. The IRGC, with its own naval branch, continues to pose a significant threat through a combination of mines, suicide boats, and shore-based missile systems, earning the strait the ominous label “Death Valley.”
Naval Challenges and Economic Implications
US minesweeping efforts in the Persian Gulf have weakened, following the decommissioning of its last dedicated minesweeper last September. Now, the Navy relies on littoral combat ships, which critics call “Little Crappy Ships” due to their operational issues. This shift leaves the region more vulnerable as Iran’s mines remain a persistent danger.
With the strait effectively blocked, nearly 15 million barrels per day of crude oil and 4.5 million barrels of refined products are trapped in the gulf. Analysts warn that storage facilities are rapidly reaching capacity, creating a potential crisis for global markets. The mines amplify risks for ships attempting to traverse the channel, making reopening the route increasingly difficult.
