WORLD • MIDDLE EAST • US-IRAN WAR 2026 • ENERGY CRISIS
A bombshell Pentagon assessment presented to the US House Armed Services Committee warns that clearing Iranian mines from the Strait of Hormuz could take up to six months — even after a peace deal is reached. With 20+ GPS-guided mines already deployed across a danger zone 14 times the size of Paris, the world’s most critical oil waterway faces a crisis that could outlast the war itself.

The war between the United States and Iran may one day end at the negotiating table in Islamabad or Geneva. But here is the chilling reality that a classified Pentagon briefing delivered to Congress on Tuesday revealed: even after a peace deal is signed, the Strait of Hormuz — through which one-fifth of the world’s traded oil flows in peacetime — may remain a minefield for up to six more months.
The Washington Post, citing three officials familiar with the briefing, reported on April 22 that members of the House Armed Services Committee were told that Iran may have deployed more than 20 naval mines in and around the strait. Some were dropped by boat. Others were released using GPS-guided technology that allows them to drift to programmed positions — making them extraordinarily difficult for US forces to detect, let alone neutralise. The assessment added that a mine-clearing operation was unlikely to begin before the war ends.
“A six-month closure of the Strait of Hormuz is an impossibility and completely unacceptable to the Secretary.”

The Pentagon pushed back hard. Spokesman Sean Parnell called the Washington Post’s reporting “cherry-picked and false,” saying the outlet had cherry-picked leaked information from a classified briefing. “By deciding to publish these false claims, the Washington Post has made clear they care more about advancing an agenda than truth,” he said. However, Parnell did not deny that the briefing took place, that mines exist, or that a mine-clearing operation poses significant challenges.
What makes these mines so dangerous — and so hard to remove
Iran possesses a formidable naval mining capability. According to the Defense Intelligence Agency, Iran holds a stockpile of more than 5,000 naval mines — making it one of the most mine-capable nations in the world. These are not simple contact explosives. Iran has acquired and developed sophisticated moored mines, bottom mines, and drifting mines that can be triggered by acoustic, magnetic or pressure signatures of passing ships.
The GPS-guided variant is particularly alarming. Unlike traditional mines anchored to the seabed, GPS-guided mines can be programmed to drift to specific locations in shipping lanes, then activate. They leave no visible trail. They generate no radar signature. Standard minesweeper sonar can detect bottom or moored mines but has far more difficulty locating drifting units in the shallow, current-filled waters of the Strait of Hormuz — where depths range from just 25 to 60 metres.
Making matters worse: a New York Times investigation reported that Iran itself has lost track of some of the mines it planted. The IRGC deployed them rapidly at the start of the conflict and may not have maintained accurate records of all positions. This means even Iran cannot hand over a complete map of the minefield in any future peace negotiation — a terrifying scenario for any ship attempting to transit the strait.
The 1,400 km² danger zone — 14 times the size of Paris
Iran’s Revolutionary Guard has formally warned shipping of a “danger zone” covering 1,400 square kilometres — an area 14 times the size of Paris — where mines may be present. This zone encompasses the core of the Strait of Hormuz shipping lanes. No commercial vessel can safely enter this zone without risk of hitting a mine. Even the Hapag-Lloyd, one of the world’s largest container shipping companies, has said its vessels need details on viable alternative routes — because fear of mines is keeping captains away even when official corridors are announced as “open.”
When the Strait of Hormuz briefly reopened at the start of the ceasefire in early April, only a handful of ships trickled through — not because Iran blocked them, but because captains and shipping companies refused to risk their vessels, crews and cargo to mines that may or may not be in their path. The strait is open on paper. In practice, it remains a war zone.

London talks — 30 countries plan mine clearance mission
On Wednesday, April 23, London hosted an emergency summit of military planners from more than 30 countries to discuss a UK and France-led multinational mission to protect navigation in the Strait of Hormuz once hostilities end. The “defensive” coalition — announced by UK Prime Minister Sir Keir Starmer and French President Emmanuel Macron — is focused on two objectives: protecting shipping from attack, and conducting mine clearance operations once the war ends.
Trump, however, was dismissive. He posted on Truth Social: “Now that the Hormuz Strait situation is over, I received a call from NATO asking if we would need some help. I TOLD THEM TO STAY AWAY, UNLESS THEY JUST WANT TO LOAD UP THEIR SHIPS WITH OIL. They were useless when needed, a Paper Tiger!” The post underlined deepening divisions between the US and NATO allies over the management of the Iran war’s aftermath.
Historical precedent provides a sobering benchmark. After the 1990–91 Gulf War, a multinational coalition force took more than two years to remove hundreds of mines and declare the northern Gulf mine-free, according to US naval mine warfare researcher Scott Truver. The Hormuz situation involves fewer mines but far more technically sophisticated ones — and the political will to begin clearing them does not yet exist while the war continues.
What this means for oil prices, India and the global economy
The economic stakes are enormous. The average cost of gasoline in the US stood at $4.02 per gallon on April 23 — up from $2.98 just before the US-Israel strikes on Iran began on February 28. That is a 35% surge in fuel prices in under two months. A six-month mine clearance timeline, if accurate, means oil markets face sustained disruption through the US midterm elections — a politically explosive outcome for Trump’s Republican Party.
For India, the impact is direct and severe. The Strait of Hormuz is the primary route for India’s oil imports from the Gulf, which account for roughly 60% of India’s total crude imports. A sustained Hormuz closure means higher energy import bills, rising inflation, a weaker rupee and continued pressure on Indian equity markets. The Sensex crashed 700 points today partly due to these fears. Indian shipping companies face rerouting costs via the Cape of Good Hope that add 10–15 days and significant fuel expenses to every Gulf voyage.
The IMF has already cut global growth to 3.1%, describing the Hormuz closure as the worst oil supply shock since 1973. Fertiliser prices are rising 20% due to disrupted gas exports through the strait — threatening food security across Africa and South Asia. If the mine clearance timeline stretches to six months as the Pentagon assessment suggests, the cumulative economic damage will dwarf anything seen since the 2008 financial crisis.
Frequently asked questions (People Also Ask)
How many mines has Iran placed in the Strait of Hormuz?
According to a Pentagon briefing to the House Armed Services Committee, Iran may have deployed 20 or more naval mines in and around the Strait of Hormuz. Some were anchored by boat; others were released using GPS-guided technology that allows them to drift to targeted shipping lane positions, making detection extremely difficult.
How long will it take to clear the Hormuz mines?
A Pentagon assessment shared in a classified briefing estimates up to six months to fully clear the Strait of Hormuz of Iranian mines — and only after the war ends. Pentagon spokesman Sean Parnell disputed the six-month figure, calling it “inaccurate,” but did not provide an alternative timeline. Historical precedent: after the 1990–91 Gulf War, mine clearing in the northern Gulf took over two years.
Why can’t Iran remove its own mines?
The New York Times reported that Iran has lost track of some of the mines it planted in the Strait of Hormuz and lacks the technical capacity to recover them all. Iran deployed them rapidly at the start of the war. GPS-guided mines in particular can drift from their original positions, making recovery even more difficult for the nation that placed them.
What is the Hormuz danger zone?
Iran’s Revolutionary Guard has officially warned of a danger zone covering 1,400 square kilometres — 14 times the area of Paris — in and around the Strait of Hormuz where naval mines may be present. Commercial shipping companies including Hapag-Lloyd have said they need safe route information before they will risk their vessels transiting this zone.
Who is leading mine clearance operations in Hormuz?
The UK and France are leading a multinational “defensive” coalition that hosted military planners from more than 30 countries in London on April 23, 2026. The mission is focused on protecting navigation and conducting mine clearance once the Iran war ends. The US Navy has also begun limited mine-clearing operations in the strait, though Iran’s Revolutionary Guard has threatened to attack any military vessels attempting to enter the channel.
How does the Hormuz mine crisis affect India?
India imports roughly 60% of its crude oil through the Strait of Hormuz. A sustained six-month closure means higher oil import bills, rising petrol and diesel prices, inflationary pressure, rupee depreciation and continued stock market stress. The Sensex has already fallen 700 points today partly due to this crisis. Indian shipping firms face longer, costlier rerouting via the Cape of Good Hope for every Gulf voyage.
What happens next
The Hormuz mine crisis creates a deeply uncomfortable reality for any peace negotiation: even a signed deal between the US and Iran does not reopen the world’s most important oil waterway. Six months of mine clearance means six more months of elevated oil prices, disrupted supply chains, and economic pain for importing nations — from India and Japan to Germany and the United States itself.
The London coalition is a significant step toward a post-war plan, but it cannot begin work until hostilities formally end. In the meantime, every day the US-Iran ceasefire holds without a deal is another day that ships wait in anchorage, oil markets price in fear, and the global economic cost of this war grows larger. The mines in the strait are not just a military problem. They are a time bomb under the world economy. Follow our live coverage of the US-Iran war at techsunnews.com for the latest updates.
