The Trump administration expanded Operation Economic Outcast to Iran’s aviation sector, sanctioning 27 Iranian airlines and nine foreign entities, cargo providers and sales agents accused of supporting the industry and helping Mahan Air obtain U.S.-origin aircraft. The ostensibly private civilian carrier has operated under U.S. sanctions for more than a decade and is accused by the United States and other governments of ferrying cash, weapons and personnel for the Islamic Revolutionary Guard Corps and supporting its allies in the region and beyond. The Treasury Department’s Office of Foreign Assets Control also suspended three Iran-related aviation authorizations, including permissions for overflights and certain non-U.S. flights into Iran. Treasury said Mahan received at least three Boeing 777 aircraft this summer after retired jets were routed through the United Arab Emirates and Oman, with ECT Aviation Support and Sky Phoenix allegedly acting as intermediaries. The action follows a recent push by the Trump administration to ground Mahan and builds on its 2011 designation for supporting the Islamic Revolutionary Guard Corps-Quds Force, as well as a broader campaign targeting Iran-linked finance, shipping, technology, gold and digital assets.
