The US State Department launched the Maritime Freedom Construct (MFC) alongside CENTCOM on 30 April 2026, describing it as a diplomatic hub to provide "real-time information, safety guidance, and coordination to ensure vessels can transit securely" through the Strait of Hormuz1. CENTCOM is the US Central Command responsible for the Middle East theatre; the MFC is the State Department's first dedicated diplomatic instrument for Hormuz governance since the blockade began. State named no member countries in the announcement, signed no framework document, and cited a diplomatic cable as the launching instrument.
A diplomatic hub without member countries cannot publish rules of engagement, the legal documents that would bind it, because rules of engagement require signatories. The United Kingdom and France lead a parallel coalition through the Northwood Permanent Joint Headquarters and the Paris track, with more than 50 named participating countries. Northwood is drafting rules of engagement now; the MFC has none yet to draft. Oman and Iran had already drafted a bilateral transit protocol in March, the structural inheritance behind Khamenei's same-day "new management" statement; the surrounding US posture sits in the prior week's blockade messaging.
The MFC reads as a counter-announcement to Khamenei's written statement rather than an operational instrument, the announcement repackages existing CENTCOM tasking under a State Department brand. Whether the MFC names member countries before the European track publishes rules of engagement is the documentation race that will determine which framework prices Hormuz transit risk.
