Tracking the shadow fleet: How Iran evaded the US naval blockade in Hormuz

Using fake flags, ammunition companies and disabled tracking signals, a immense web of vessels bypassed the US naval blockade of the Strait of Hormuz.

On March 11, the Thai cargo vessel Mayuree Naree was struck by 2 projectiles portion crossing the Strait of Hormuz, 1 of the world’s astir important waterways located betwixt Iran and Oman.

Their remains were recovered weeks aboriginal erstwhile a specialised rescue squad boarded the vessel, which had tally aground connected the shores of Iran’s Qeshm island.

At astir the aforesaid time, a “shadow fleet” of tankers continued to navigate the precise aforesaid waters safely.

Following a impermanent ceasefire connected April 8, the United States imposed a afloat naval blockade connected Iranian ports connected April 13. Theoretically, postulation done the strait should person travel to a implicit halt.

However, tracking information reveals a remarkably antithetic reality.

An exclusive Al Jazeera open-source probe tracked 202 voyages made by 185 vessels done the strait betwixt March 1 and April 15, navigating some nether occurrence and crossed blockade lines.

The numbers down the shadows

To recognize however the strait operated nether utmost pressure, Al Jazeera’s Digital Investigative Unit monitored the waterway daily, cross-referencing vas International Maritime Organization (IMO) numbers with planetary authorisation lists from the US Office of Foreign Assets Control (OFAC), the European Union, the United Kingdom and the United Nations. An IMO fig is simply a unsocial seven-digit fig assigned to commercialized ships.

Of the tracked voyages, 77 (38.5 percent) were straight oregon indirectly linked to Iran. Notably, 61 of the ships transiting the strait were explicitly listed connected planetary sanctions lists.

The probe divided the struggle into 3 chiseled phases to representation the fleet’s behaviour:

• Phase 1: Open War (March 1 – April 6): 126 ships crossed the strait, peaking astatine 30 vessels connected March 1. Among these, 46 were linked to Iran.
• Phase 2: The Truce (April 7 – 13): 49 ships crossed during this fragile pause. More than 40 percent of these vessels were tied to Iran, including the US-sanctioned, Iranian-flagged Roshak, which successfully exited the Gulf.
• Phase 3: The US Blockade (April 13 – 15): Despite the explicit naval blockade, 25 ships crossed the strait.

Breaking the blockade

When the US blockade took effect, the shadiness fleet adapted immediately.

The Iranian cargo vessel “13448” successfully broke the blockade. Because it is simply a smaller vas operating successful coastal waters, it lacks an authoritative IMO number, allowing it to evade accepted sanction-monitoring tools. The vas departed Iran’s Al Hamriya larboard and reached Karachi, Pakistan.

Similarly, the Panama-flagged Manali broke the blockade, crossing connected April 14 and penetrating the cordon again connected April 17 en way to Mumbai, India.

The probe uncovered wide manipulation of Automatic Identification System (AIS) trackers. Vessels specified arsenic the US-sanctioned Flora, Genoa and Skywave deliberately disabled oregon jammed their signals to fell their identities and destinations.

Fake flags and ammunition companies

To obscure eventual ownership, the shadiness fleet heavy relies connected a analyzable web of “false flags” and ammunition companies. The probe identified 16 ships operating nether fake flags, including registries from landlocked nations similar Botswana and San Marino, arsenic good arsenic others from Madagascar, Guinea, Haiti and Comoros.

The operational web managing these ships spans the globe. Operating firms were chiefly based successful Iran (15.7 percent), China (13 percent), Greece (more than 11 percent) and the United Arab Emirates (9.7 percent). Notably, the operators of astir 19 percent of the observed vessels stay unknown.

The toll of a parallel system

Despite the aggravated subject pressure, vigor carriers dominated the traffic, with 68 ships (36.2 percent) transporting crude oil, petroleum products and gas. Ten of these tankers were straight linked to Iran. Non-oil commercialized besides persisted, with 57 bulk and wide cargo ships crossing during the unfastened warfare phase, 41 of which were tied to Tehran.

Before the war, astatine slightest 100 ships crossed the Strait of Hormuz daily. Today, a staggering 20,000 sailors are trapped connected 2,000 ships crossed the Gulf – a situation the International Maritime Organization described arsenic unprecedented since World War II.

A shadiness Iranian fleet, meanwhile, has been navigating seamlessly arsenic portion of a parallel maritime strategy calved from 47 years of US sanctions connected Tehran. Washington slapped sanctions connected Tehran pursuing the 1979 Islamic gyration that toppled the pro-Washington ruler Shah Mohammad Reza Pahlavi. The 2 countries person had nary diplomatic ties since 1980.
