The 35 Ships: How Iran's Revolutionary Guard Positions Itself as the Strait of Hormuz's Security Anchor

The Islamic Revolutionary Guard Corps Navy confirmed on May 22, 2026, that 35 commercial vessels — including oil tankers, container carriers, and general cargo ships — transited the Strait of Hormuz under its coordination over the preceding 24 hours. The announcement, carried simultaneously by Tasnim, Mehr News, and Alalam, described the movement as a security escort operation. The number alone is not remarkable: Hormuz is one of the world's most heavily trafficked maritime corridors, and comparable vessel counts cross daily. What is significant is the framing. The IRGC presented itself, explicitly, as the coordinating authority for safe passage.

That matters. The Guard Corps has been one of the primary instruments of Iranian coercive pressure in the Gulf — detaining vessels, boarding ships, threatening closure. To announce that 35 ships moved under IRGC coordination within a 24-hour window is not merely an operational report. It is a statement of institutional identity: we are the ones who keep this corridor open, and we choose to do so.

The message has multiple recipients. It reaches European energy buyers who need reassurance that Iranian escalation will not interrupt their supply chains. It reaches Washington, where the Trump administration has maintained maximum-pressure sanctions while engaging in indirect nuclear talks in Muscat, Oman — a process in which maritime normalisation is a practical reward Iran has sought in exchange for concessions on enrichment. And it reaches the Gulf's own monarchies, who watch the IRGC's every movement with particular alertness and who have historically preferred that American naval power, not the IRGC, guarantee their commercial lifelines.

What the corridor carries — and why that matters now

The Strait of Hormuz is the world's most consequential maritime chokepoint. Roughly 20 percent of global oil output and 30 percent of global liquefied natural gas pass through its narrow waters, which at their narrowest span just 33 kilometres of navigable passage between Iranian territory and Oman. It is the umbilical cord connecting Gulf producers — Saudi Arabia, the UAE, Kuwait, Iraq, Qatar, Iran itself — to Asian refining markets, European import terminals, and the broader apparatus of global trade.

The volume of 35 ships in 24 hours is not anomalously high. Traffic through the corridor runs at that scale almost every day under normal conditions. But the context is not normal. Tensions between Iran and the United States have remained elevated since the collapse of the JCPOA in 2018; the current nuclear negotiations, hosted by Oman with European and indirect American participation, have produced no binding agreement; and the broader atmosphere of US-China trade confrontation — with tariffs affecting global shipping insurance, commodity pricing, and Chinese import demand — has injected additional volatility into Gulf energy markets.

The IRGC Navy's announcement, arriving at the start of a new trading week and disseminated across four state-aligned Telegram channels within a 90-minute window, carries the hallmarks of a deliberate information operation. It is targeted at the commercial maritime community: shipowners, insurers, charterers, port operators. The message, stripped of jargon, is: we are not an obstacle. We are an asset.

The counter-argument — and why it deserves serious attention

It would be straightforward to read this announcement as propaganda — the IRGC manufacturing a display of competence to serve domestic political purposes or to improve its negotiating posture ahead of the Muscat talks. That reading has merit. Iranian state media frequently amplifies military and security achievements, sometimes well beyond their operational significance. The 35-ship figure cannot be independently verified from non-Iranian sources within the available record, and the IRGC has strong incentives to present a veneer of control that its actual capacity may not match.

But the counter-argument deserves equal weight. The IRGC Navy has genuinely had the operational capability to interfere with Gulf shipping for years — and has used it, selectively, most notably in the seizure of tankers and the mining of vessels during periods of acute escalation. Its choice not to disrupt these passages is a meaningful signal. Announcing that it coordinated them rather than merely tolerating them is a different kind of statement: not a concession made under pressure, but a claim of positive agency.

The more important question is whether this posture reflects a strategic reorientation or a temporary tactical choice. Iran has both domestic hardliners who view maritime confrontation as an appropriate tool and pragmatic actors who understand that the sanctions burden makes commercial normalisation economically vital. The 35-ship announcement may represent an agreement within the Iranian system that the current moment rewards restraint — or it may reflect a temporary freeze while nuclear talks continue, with a return to coercive signalling if the Muscat negotiations fail.

History, precedent, and the leverage calculation

The Strait of Hormuz has been a site of Iranian leverage since the Iran-Iraq War of the 1980s, when the so-called Tanker War saw both Baghdad and Tehran target commercial vessels in the Gulf as a means of pressuring the other side's export revenues. The experience left a durable imprint on Iranian strategic thinking: the Strait is not merely a geographic feature but a political instrument, and Iran controls the geography. No other state in the Gulf possesses that geographic advantage to the same degree.

The last major period of overt Iranian threats to close or restrict the Strait came in 2019, when Iranian officials signalled that if sanctions deprived Iran of its own oil revenues, it would target the revenues of others. Those threats did not result in closure — the operational difficulties of actually sealing a passage as wide as Hormuz, combined with the certain retaliation from a US-led naval coalition, made them largely rhetorical. But they illustrated the persistent logic: the Strait is Iran's most credible coercive instrument precisely because it is not Iran's to close absolutely, but Iran's to make costly for everyone else.

The current announcement sits in a different register. Rather than threatening disruption, it claims credit for facilitation. The IRGC is not saying Hormuz is dangerous; it is saying the IRGC makes Hormuz safe. That is a significant reframing — from instrument of coercion to provider of a public good — and it signals that Iranian strategic communications have adapted to a context where they need Western and Asian commercial actors to view them as legitimate partners rather than rogue disruptors.

The precedent matters because it demonstrates that Iran can modulate its approach to the Strait depending on what it calculates serves its interests. During periods of acute hostility — 2019, the US drone strike that killed Quds Force commander Qasem Soleimani in 2020 — the IRGC leaned toward threat escalation. During periods of negotiation and economic pressure, it can lean toward reassurance. The 35-ship announcement is the latter mode, fully activated.

Stakes and what comes next

The nuclear talks in Muscat remain the central variable. The Trump administration has stated publicly that it will not accept an Iranian enrichment programme at the level Iran currently maintains — Iran has enriched to approximately 84 percent purity, according to the most recent International Atomic Energy Agency reporting, a level technically close to weapons-grade — while Iran has insisted that its enrichment programme is a sovereign right under the Non-Proliferation Treaty and will not be rolled back to the pre-2018 levels the JCPOA once imposed.

A breakdown in those talks would likely shift Iranian behaviour across multiple domains, including the maritime. The Guard Corps has demonstrated before that when political signals from Tehran shift toward confrontation, its naval arm follows. The 35-ship announcement should be read as a contribution to the negotiating atmosphere — an assertion of value that Iran believes Western parties and commercial actors will relay to their governments as evidence that accommodation, not confrontation, defines Iranian behaviour in the Gulf.

Separately, the broader trajectory of Gulf energy infrastructure investment suggests that Hormuz's strategic weight will grow rather than diminish over the coming decade. Saudi Aramco, ADNOC, and their Gulf counterparts are directing capital toward downstream petrochemical complexes — the Rabigh refinery expansion, the Borouge complex in Abu Dhabi — that increase the region's processing capacity and reduce its dependence on shipping crude through the Strait in its raw form. Those complexes still need feedstock, still need to export products, and still rely on the same corridor for the margins that fund national budgets. The Strait does not become less important as Gulf states move downstream; it becomes a more complex political object, because the cargo it carries becomes more valuable and the actors with a stake in its stability diversify.

The announcement on May 22 will not resolve any of those tensions. But it should be read for what it is: a signal that Iran has decided, at least for now, that the more valuable posture is that of a security guarantor than a commercial disruptor. Whether that decision holds through the Muscat negotiations — and beyond — will be among the more consequential geopolitical questions in the Gulf over the next eighteen months.

The 35 ships passed without incident. Whether they do so again, and under what conditions, will tell us a great deal about where Iranian strategy is heading.
