The U.S. military has issued a stern warning to ships navigating the Strait of Hormuz, advising them to be ready for potential boarding as it enforces a blockade ordered by former President Donald Trump.

On Wednesday, the U.S. Central Command (CENTCOM) shared an audio recording of the serious radio transmission, even as Trump declared that he was “permanently opening” the Strait.

“The United States has formally announced a blockade of Iranian ports along the coast,” a military official stated in the communication.

The officer further advised, “This action is within legal bounds. All vessels should immediately return to port if departing, and if Iran is your next destination, cease all transit to avoid breaching the blockade.”

The officer issued a firm warning that any ships attempting to break the blockade “will face boarding, interdiction, and seizure,” adding, “We are prepared to use force.”

This military announcement stands in stark contrast to Trump’s earlier comments on Truth Social, where he claimed that the strait is “permanently open” following private discussions with Chinese President Xi Jinping, asserting that Xi had agreed to halt arms supplies to Iran.

‘China is very happy that I am permanently opening the Strait of Hormuz,’ Trump wrote on Truth Social. ‘I am doing it for them, also – And the World. This situation will never happen again.’

A senior White House official told the Daily Mail that, despite Donald Trump’s promise to reopen it, ‘the blockade is fully in effect and working.’ It remains unclear whether Trump was declaring the strait open to shipping traffic immediately or signaling an intent to reach a permanent resolution as peace talks with Iran continue.

After peace talks with the Islamic regime collapsed over the weekend, the President launched a naval blockade of Hormuz, a critical oil chokepoint through which one-fifth of the world’s supply flows.

Trump imposed the blockade to push Tehran back to the negotiating table, with the President reportedly reluctant to resume the bombing campaign, which has brought chaos to the Middle East.

During the start of Operation Epic Fury, Iran retaliated by choking off traffic through the strait with swarms of explosive speedboats, drones, and naval mines.

The regime has also sought to impose de facto tolls on passing oil tankers, allowing favored partners like China and India to transit more freely while pressuring Western vessels.

The blockade has sparked condemnation from China who is the number one importer of Iranian oil. 

Xi Jinping called Trump’s decision ‘dangerous and irresponsible’ while demanding the world must not ‘revert to the law of the jungle.’

Since the blockade has gone into effect, ships operating in the Gulf have begun adopting tactics to avoid detection to by the US military, according to the New York Times.  

‘Now, we are starting to see vessels going dark or using ‘zombie’ or random identification,’ Ami Daniel, a maritime intelligence data analyst, told the paper.

The report notes that in the past 24 hours ships linked to Iran have begun manipulating the global system used to surveille maritime traffic as the move in and out of Iranian ports. 

On Tuesday, the US military blocked six oil tankers from passing through the strait.

The Pentagon, meanwhile, is preparing to send 6,000 more troops to the region aboard the USS George HW Bush and several other warships.
