U.S, U.K and Belgium Mobilize Drones to Clear Hormuz Mines

World · Defense Industry

The Strait of Hormuz carries about a fifth of global oil traffic and a quarter of liquefied natural gas exports. Since the US-Israeli strikes on Iran in late February 2026, that traffic has collapsed. Iran’s mine warfare campaign and its rerouting orders forced commercial vessels into coastal channels under Tehran’s control. The defense industry — General Dynamics, BAE Systems, Raytheon, Thales and their European counterparts — is now mobilising the largest collection of unmanned mine countermeasures platforms ever assembled for a single operation. Belgian, UK, and other allied capabilities are joining the force package. Trump’s overnight strike suspension on Iran is real but does not change the underlying need: the strait still has to be cleared, the world economy depends on it, and the technology to do it has shifted from manned ships to autonomous drones.

What is the demining operation actually doing?

The Rio Times, the Latin American financial news outlet, reports that the US Navy and allied forces are deploying a combination of manned and unmanned platforms to detect, identify and neutralise sea mines across the Strait of Hormuz. The operation, currently part of Operation Epic Fury, uses a three-stage process. First, autonomous underwater vehicles equipped with synthetic-aperture sonar map the seabed and identify mine-like objects. Second, the data is transmitted to crews operating outside the minefield, who confirm the threat identification. Third, neutralisation systems — either the expendable Archerfish explosive devices or remotely operated boats towing mine-sweeping sleds — destroy the confirmed mines. The Strait of Hormuz is between 60 and 80 kilometres wide at its narrowest section, with mines potentially planted at the seabed, tethered just below the surface, drifting freely, or attached as limpets to vessel hulls.

Which defense companies are making the equipment?

General Dynamics produces the Knifefish, an autonomous underwater vehicle designed for detection, classification and identification of buried mines and mines in high-clutter environments. The platform operates as an off-board sensor while host ships remain outside minefield boundaries, reducing personnel risk. BAE Systems produces the Archerfish, a torpedo-shaped 2-meter remotely operated device carrying an explosive charge — designed as expendable equipment costing tens of thousands of dollars per unit. Raytheon (RTX) produces the Barracuda, a semi-autonomous mine neutralizer. Thales operates the AQS-20C sonar cylinders deployed from MH-60S helicopters. The Naval Sea Systems Command has been working with industry for years on the Mine Countermeasures Unmanned Surface Vehicle (MCM USV), a high-speed drone boat platform designed to autonomously hunt and destroy mines using sonar.

How are allies contributing?

The UK has pledged a force package that includes destroyer HMS Dragon (D35), Typhoon fighter aircraft, autonomous Kraken drone boats and unmanned surface vessels. The UK Ministry of Defense confirmed the package May 13 contingent on a “sustainable” US-Iran ceasefire agreement. Belgium has committed its mine countermeasures capability, which Defense Minister Theo Francken described as “world-class” — Belgium operates among Europe’s most advanced naval mine warfare programmes. Other NATO partners are coordinating contributions through ongoing meetings. The multinational dimension is essential: the Iranian mine inventory is estimated at thousands of devices and clearing such a quantity requires platform diversity, redundancy and personnel beyond what the US Navy alone can deploy. Ukraine has also been informally consulted: since 2022, Russia has dropped thousands of mines across the Black Sea, and Ukrainian engineers developed innovative solutions including the TLK-150 surface drone.

Why is autonomous mine countermeasures the new model?

The US Navy has neglected the mine countermeasures mission for over twenty years, according to Scott Savitz, a senior engineer at the RAND Corporation who previously advised the Navy’s mine warfare command. The traditional Avenger-class minesweepers are being phased out of service; only four were operational in late March 2026, with two in maintenance in Singapore. The shift to autonomous platforms is therefore both technological progress and necessity. The structural argument: a metal-hulled ship cannot safely enter a minefield, so it must remain outside the threat zone. Autonomous platforms can operate in the minefield without crew risk. AI-enabled data analysis onboard unmanned vessels speeds the identify-and-neutralise loop. The longer-term ambition, according to Mark Bock of Thales’ US Navy business, is groups of unmanned systems that search, identify and destroy mines in a single autonomous workflow rather than the current multi-step process.

Does Trump’s Iran de-escalation change the operation?

Yes, but not in the way headlines suggest. The Trump-Iran strike suspension overnight changes the political probability of further escalation but does not change the operational reality on the water. The mines that were placed in late February and March 2026 are still present. Drifting mines could still be in the channels. Limpet mines may be on vessel hulls. Even with a sustainable ceasefire, the strait does not become navigable without active clearance. The UK force package is explicitly conditioned on a “sustainable” ceasefire — meaning the demining force enters once the security risk to clearance crews is materially reduced. The technology, the contracts, the platforms and the international coordination are all proceeding regardless of the negotiation status. The operation has a 6-12 month horizon at minimum.

What should investors and analysts watch next?

• Defense industry contract awards: Knifefish (General Dynamics), Barracuda (Raytheon), Archerfish (BAE Systems) and Kraken (UK) production scaling will be the operational signals.
• The US-Iran ceasefire status: the UK package is explicitly conditioned on a sustainable ceasefire. Trump’s overnight pause is necessary but not sufficient.
• Commercial vessel traffic statistics: the daily count through Hormuz against pre-war 130 daily ships. Restoration to 50% would imply effective clearance is underway.
• Brent price response: sustained reopening would push Brent below $80; failure of operations would keep it above $100.
• Belgian defense procurement: Belgium’s MCM commitment may accelerate broader European defense industrial spending — a Europe-wide policy shift with implications well beyond Hormuz.

Frequently Asked Questions

How many mines did Iran place?

Public estimates are uncertain. Iran has access to multiple mine categories — bottom mines that detonate when ships pass overhead, tethered mines anchored below the surface, drifting mines, and limpet mines for hull attachment. The Iranian inventory is believed to be in the thousands, though confirmed deployment numbers are classified. The clearance operation must assume the worst case — entire channels potentially contaminated — which is why the multinational force package and the 6-12 month operational horizon.

How long will clearing the strait take?

The Wall Street Journal cited estimates of weeks to months even after the mine-clearing mission succeeds, before normal traffic resumes. The next likely step is military escorts for ship convoys — but convoys move only 5-10 ships at a time, far below the pre-war daily 130. Clearing the operational backlog of vessels (as of March, 1,129 ships in the Gulf area) would take months. The US Navy, already worn down by lengthy deployments, has approximately 292 battle force ships compared with over 500 during the 1980s “Tanker War” — capacity for prolonged escort missions is constrained.

What is the cost of the operation?

Direct platform costs run from tens of thousands of dollars per expendable device (Archerfish) to tens of millions per Littoral Combat Ship or destroyer. The total operation cost — including personnel, fuel, maintenance, and the depreciation of high-value platforms — is likely in the billions over the full clearance timeline. The cost is borne primarily by the US defense budget, with allied contributions from the UK, Belgium and others.

Could Brazilian or Latin American firms be involved?

Marginally. Brazilian defense industry capabilities in unmanned maritime systems are limited. Embraer‘s defense unit produces aircraft platforms but not naval drones. The Brazilian Navy has been observing the operation as a doctrinal case study. The longer-term implication for Latin America is that Brazilian, Mexican and Chilean naval procurement may shift toward unmanned platforms over the next decade — but the Hormuz operation itself is a NATO-aligned effort with limited Latin American direct participation.

Will autonomous mine warfare become standard?

Yes. The Hormuz operation is being explicitly described by US Navy commanders as the laboratory for the next-generation mine countermeasures “kill web.” The combination of MH-60S laser systems, autonomous underwater vehicles, semi-autonomous neutralizers and AI-enabled data analysis represents the future of the mission. The Avenger-class manned minesweeper is being phased out globally. The defense industrial base — General Dynamics, BAE, Raytheon, Thales, Northrop Grumman — is restructuring around the autonomous platform thesis. The shift will outlast the Hormuz operation by decades.
