Ships Turn Off Trackers to Transit Strait of Hormuz Amid War Fears

The Strait of Hormuz, a critical artery for global energy supplies, is increasingly at the center of the escalating conflict involving Iran, Israel, and the United States. Recent days have seen a surge in tensions as attacks on commercial vessels near the strait intensify, prompting a historic release of oil reserves aimed at stabilizing prices. While a complete closure of the strait remains averted, the situation is fluid and fraught with risk, with several ships employing evasive maneuvers to navigate the waterway.

At least six vessels have transited the Strait of Hormuz since March 6, according to data reviewed by CNN and MarineTraffic, a maritime tracking service. A significant number of these ships have taken steps to obscure their movements, either by switching off their Automatic Identification System (AIS) – a mandatory tracking system – or attempting to conceal their actual positions. This behavior suggests a heightened level of concern among shipping companies regarding potential attacks.

Navigating a Minefield: Vessel Tactics and Iranian Warnings

Among the vessels identified is the Dalia, an Iranian-flagged oil and chemical tanker sanctioned by both the US Treasury Department and the European Union. These sanctions target entities involved in Iran’s proliferation of weapons of mass destruction and support for terrorism. The Dalia deactivated its AIS transponder on March 8 while approaching the strait from the east, reactivating it on March 10 after passing through, and subsequently docking at Bandar Imam Khomeini port in Iran. Similar tactics were employed by the Shenlong, a Liberian-flagged crude oil tanker that arrived in Mumbai, India, on March 11, and the KSL Hengyang, a bulk carrier sailing under the Jordanian flag.

The evasive maneuvers aren’t limited to simply disabling tracking systems. The Palau-flagged Parimal tanker experienced GPS jamming on March 7 while traversing the strait, further illustrating the challenges faced by vessels. Adding to the complexity, some ships have begun broadcasting unusual messages, seemingly intended to deter potential attacks. These messages, typically used for destination port information, now include declarations like “CHINAOWNERALLCHINESE” and “CHINA OWNER&CREW,” potentially signaling a desire to avoid being targeted.

These actions follow warnings from the Iranian military that any ship attempting to pass through the Strait of Hormuz would be considered a target. This declaration effectively closed the strait, a vital chokepoint for roughly one-fifth of the world’s crude oil shipments. The situation prompted an unprecedented response from global powers, with countries agreeing to release a record 400 million barrels of oil from strategic reserves in an attempt to mitigate potential price spikes.

Escalation and Regional Fallout

The attacks near the Strait of Hormuz are occurring against a backdrop of escalating conflict. Iran has claimed to have launched its “heaviest operation” since the start of the war, while Israel has responded with an “additional wave” of strikes in Tehran. The conflict has already resulted in significant casualties, with Iran’s UN ambassador reporting over 1,300 Iranian deaths and at least 630 deaths reported in Lebanon due to Israeli strikes. The United Nations has expressed deep concern over the escalating violence and called for de-escalation.

The internal political situation within Iran is also adding another layer of complexity. Mojtaba Khamenei, Iran’s new Supreme Leader, reportedly sustained a fractured foot and facial lacerations on the first day of the war, according to a source cited by CNN. His limited public appearances since his appointment following the death of his father, Ayatollah Ali Khamenei, have fueled speculation about the extent of his injuries and the stability of the Iranian leadership.

The US-Russia-Iran Trilemma

The conflict with Iran is also creating complications for the United States’ strategy regarding Russia’s war in Ukraine. President Trump had been pressuring India to reduce its purchases of Russian oil, with some initial success. However, the current crisis has led the US to grant Indian refiners a 30-day waiver to purchase Russian oil currently stranded at sea, a move seemingly at odds with the administration’s broader goals. This decision highlights the delicate balancing act the US faces in navigating multiple geopolitical challenges simultaneously.

Confirmed and Unclear Elements

Confirmed: Attacks have occurred on at least three vessels near the Strait of Hormuz. Iran has warned against passage through the strait and is reportedly laying mines in the waterway. A significant oil release has been authorized to stabilize global markets. Casualties are mounting in both Iran and Lebanon. Mojtaba Khamenei sustained injuries shortly after assuming the Supreme Leadership.

Unclear: The full extent of Iran’s mining operations in the Strait of Hormuz remains unconfirmed. The precise nature of the attacks on the vessels – including who carried them out and the types of projectiles used – is still under investigation. The long-term impact of the conflict on global oil prices and supply chains is uncertain. The full extent of Mojtaba Khamenei’s injuries and their impact on his leadership are also unclear.

What Lies Ahead: Procedural Next Steps

The immediate future will likely see continued efforts to de-escalate tensions through diplomatic channels, though the prospects for a swift resolution appear dim. The International Atomic Energy Agency (IAEA) will likely continue its monitoring of Iran’s nuclear program, seeking assurances that it remains peaceful. The United Nations Security Council may convene to discuss the situation, but any meaningful action is likely to be hampered by divisions among its members. Shipping companies will continue to assess the risks and adjust their routes accordingly, potentially leading to increased insurance costs and delays in deliveries. The US and its allies will likely maintain a military presence in the region to deter further escalation and protect shipping lanes, while simultaneously attempting to manage the fallout from the conflict on global energy markets and its broader geopolitical implications.
