US Navy Enforces Full Blockade on Iranian Ports, Says CENTCOM
The United States Central Command (CENTCOM) has announced that its naval blockade of Iranian ports is now "fully implemented," with economic trade entering and leaving Iran by sea "completely halted." In a statement posted on social media, CENTCOM said the blockade is being enforced against vessels of all nations "entering or leaving coastal areas or ports in Iran," including all Iranian ports on the Persian Gulf and the Gulf of Oman.
According to CENTCOM, more than 10,000 sailors, Marines, and Air Force personnel, along with over a dozen warships and dozens of aircraft, are involved in the operation. In the first 24 hours after the blockade took effect, no ships managed to pass, and six merchant vessels complied with US orders to turn around and "re-enter an Iranian port." The US military also reported that, since the start of the blockade, US forces have directed 28 vessels to turn around or return to port.
Scope and Implementation
According to CENTCOM, the blockade is being applied exclusively to vessels entering or exiting Iranian ports. The command explicitly stated that US forces will not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports. This clarification comes after conflicting reports about whether some ships had managed to pass through the blockade.
A Reuters report cited shipping data indicating that at least three vessels transited the strait during the first 24 hours, none of which were heading to Iranian ports. However, the AFP news agency and several US media outlets, citing data from maritime tracker Kpler, reported that two ships had transited the waterway after leaving Iranian ports on Monday. CENTCOM subsequently rejected these reports, reiterating that no ships made it past the blockade.
Economic and Strategic Impact
Admiral Brad Cooper, commander of CENTCOM, said in a statement that an estimated 90% of Iran's economy is fueled by international trade by sea. "In less than 36 hours since the blockade was implemented, US forces have completely halted economic trade going into and out of Iran by sea," he said.
Iran has described the blockade as an "act of war," according to sources cited by Al Jazeera. In response, Iran has reimposed its own restrictions on the Strait of Hormuz after previously declaring the waterway fully open last week. The strait is a critical chokepoint for global oil shipments, and any disruption could have significant implications for world markets.
The US military has amassed significant naval assets in the region, including three aircraft carriers operating simultaneously for the first time in 23 years. The carriers, along with 12 accompanying ships, more than 200 aircraft, and 15,000 soldiers, represent a major show of force. The last time such a concentration occurred was in the lead-up to the 2003 invasion of Iraq.
Diplomatic Context
The blockade follows weekend talks between the US and Iran that failed to yield an agreement on ending the war that the US and Israel launched on February 28. US President Donald Trump announced the blockade after the talks and has since said that negotiations could resume in the next two days. Trump has also threatened to destroy Iran's civilian infrastructure if the conflict escalates, a statement that has not been independently verified.
Iran has reportedly set the lifting of the naval blockade as a precondition for resuming talks. Meanwhile, Trump has extended a fragile ceasefire but indicated that the naval siege would persist. He has not set a deadline for the extended truce, suggesting he is comfortable with the status quo, which he argues is depleting the Iranian economy at a low cost to the US.
Potential Consequences
Military observers widely acknowledge that US forces have the capability to maintain the blockade for the foreseeable future. However, the continued pressure increases the likelihood of Iranian attacks, which could cause the two-week ceasefire to collapse. The situation remains tense, with the blockade's effectiveness and the potential for escalation both under close scrutiny.
As the blockade continues, the international community watches closely for any signs of a diplomatic breakthrough or further military confrontation. The impact on global oil markets and regional stability remains uncertain, but the current trajectory suggests sustained pressure on Iran's economy and continued uncertainty in the region.
