The Iran navy's new deadly warship Makran, a former aframax tanker, is not the first Iranian warship converted from a clandestinely acquired foreign merchant vessel.

The precedent was set in November 2020 when a former Italian ro-ro, the 8,700-gt Altinia (built 1992), emerged from an Iranian shipyard as the Islamic Revolutionary Guard Navy’s multipurpose heavy combat warship IRIS Shahid Roudaki.
