Danish shipping giant A.P. Moller-Maersk confirmed that its U.S.-flagged roll-on/roll-off vessel Alliance Fairfax safely exited the Persian Gulf on May 4, 2026, under U.S. military protection. The vessel, operated by Farrell Lines, a subsidiary of Maersk Line Limited, completed the transit "without incident" with all crew reported safe. The Alliance Fairfax had been unable to leave the Gulf since late February 2026, when conflict between the United States and Iran sharply escalated, leading to a near-collapse in commercial traffic through the critical maritime chokepoint amid missile, drone, and mine threats.
U.S. Central Command (CENTCOM) announced on social media that two U.S.-flagged merchant vessels successfully transited through the Strait of Hormuz on May 4, marking the first step of President Trump's Project Freedom initiative. The operation deployed U.S. Navy guided-missile destroyers, over 100 land- and sea-based aircraft, multi-domain unmanned platforms, and 15,000 service members. The identity of the second vessel has not been disclosed. The company stated that the U.S. military approached Maersk with the option to exit under protection, and after developing a detailed security plan involving both shore-side and onboard teams, the operation was approved and executed.
The Alliance Fairfax is part of the U.S. Maritime Security Program (MSP), which provides commercially operated U.S.-flagged vessels for military logistics during emergencies. It was one of five MSP/TSP vessels (along with APL Eagle, Maersk Yorktown, CS Anthem, and Stena Imperative) stranded in the Gulf when the conflict began, collectively crewed by approximately 100 American merchant mariners. Industry officials noted the operation may represent a limited extraction effort rather than full restoration of normal traffic flows. Jakob Larsen, BIMCO's Chief Safety & Security Officer, emphasized that "without consent from Iran to let commercial ships transit safely," the operation's sustainability remains uncertain.
The Strait of Hormuz is a vital waterway through which approximately 20% of the world's oil passes. Iran blocked the strait after U.S. and Israeli strikes on February 28, 2026, with the IRGC declaring full control on March 4. Prior to the conflict, around 3,000 vessels used the strait each month; in April 2026, only 191 vessels transited. Hundreds of ships remain stranded in the Gulf. The U.S. imposed a counter-blockade on Iranian ports on April 13, turning around 52 vessels as of May 6. Trump paused Project Freedom on May 6 citing "great progress" toward a deal; however, the U.S. blockade remains in effect.
