US Military Says 31 Ships Turned Back as Part of Iran Blockade, Mostly Oil Tankers
Published on Reflecto News | World News | Defense & Energy Security
United States Central Command (CENTCOM) has announced that American forces have directed 31 vessels to turn around or return to port as part of the ongoing US naval blockade against Iran, with the majority of intercepted ships identified as oil tankers . The announcement comes as tensions continue to escalate in the strategic Strait of Hormuz, with Iranian forces seizing two commercial vessels in the past 24 hours.
In an operational update posted on social media, CENTCOM noted that the maritime enforcement actions have seen high levels of cooperation, with “the majority of vessels having complied with US directions” following interception in the region .
Massive Military Operation
The blockade, which began on April 13 following President Donald Trump’s proclamation, represents a significant escalation in regional maritime security. CENTCOM disclosed that the operation involves:
| Asset | Number |
|---|---|
| US troops | More than 10,000 |
| Warships | 17 |
| Aircraft | More than 100 |

The deployment includes a mix of high-value naval and air assets such as aircraft carriers, guided-missile destroyers, amphibious assault ships, littoral combat ships, and advanced surveillance platforms. Both manned and unmanned aircraft are being used for intelligence, reconnaissance, and enforcement operations .
Blockade Rules and Enforcement
The blockade is being enforced “impartially against vessels of all nations entering or departing Iranian ports and coastal areas, including all Iranian ports on the Arabian Gulf and Gulf of Oman” . However, CENTCOM has stated that US forces “will not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports” .
The official rules of the blockade include:
| Rule | Details |
|---|---|
| Scope | All vessels entering or departing Iranian ports |
| Enforcement | Impartial against all nations |
| Neutral transit | Vessels to non-Iranian ports not impeded |
| Consequences | Interception, diversion, or capture |

Recent Maritime Confrontations
The massive naval enforcement has triggered a volatile reaction in the Middle East, with tensions boiling over after Iranian forces opened fire on three commercial ships in the Strait of Hormuz, successfully seizing two of them . The maritime confrontation represents a significant spike in hostilities within the strategic waterway, occurring only 24 hours after President Trump opted to prolong a ceasefire while simultaneously upholding the American blockade.
US forces have also taken offensive action. On April 19, the USS Spruance intercepted and disabled the Iranian-flagged cargo ship Touska, which was attempting to breach the blockade in the Gulf of Oman. The vessel was given “fair warning to stop” over a six-hour period, but the crew “refused to listen, so our Navy ship stopped them right in their tracks by blowing a hole in the engine room,” President Trump said . US Marines subsequently rappelled from helicopters onto the ship and took control of the vessel .
Iran’s top military headquarters, Khatam al-Anbiya, has vowed that the country will respond to the interception, calling it a “violation of the ceasefire” . Iranian Foreign Minister Abbas Araghchi has characterized the naval restrictions as an “act of war” and a direct breach of the existing ceasefire .
Ceasefire Status
The maritime confrontations come as a fragile ceasefire between the US and Iran, brokered by Pakistan, remains in effect. President Trump recently extended the ceasefire without setting a formal deadline, adopting a cautious strategy while communication lines remain open .
White House press secretary Karoline Leavitt clarified that the US has refrained from setting a formal deadline for the current truce extension. Nevertheless, she emphasized that a non-negotiable requirement for any permanent agreement would involve Iran consenting to surrender its entire stockpile of enriched uranium .
President Trump has asserted that the naval blockade will persist until such time as Tehran presents a formal proposal and discussions lead to a definitive outcome .
Economic Impact
The White House has declared that the United States is “completely strangling” Iran’s economy through the blockade, with Press Secretary Karoline Leavitt telling reporters that Tehran is losing an estimated $500 million per day. The blockade has severely restricted Iran’s ability to export oil, its primary source of foreign revenue.
What Comes Next
The situation remains highly volatile. As the US blockade continues and Iran retaliates with ship seizures, the risk of further military escalation remains elevated.
| Scenario | Likelihood | Implications |
|---|---|---|
| Continued standoff | Likely | Ceasefire holds, but no progress |
| Further ship seizures | Elevated | Iran may continue targeting vessels |
| US military response | Possible | Could escalate conflict |
| Diplomatic breakthrough | Unlikely | Would require major shift from Iran |
The coming days will determine whether the ceasefire can withstand these escalating maritime tensions. For now, the US continues to tighten its blockade, and Iran has shown it will respond in kind.
