IRIS Makran (Persian: مکران) is the first and only forward base ship of the Islamic Republic of Iran Navy, in service with its Southern Fleet since 2021 and named after a coastal region in southeastern Iran.
A former crude oil tanker converted into a warship, she was known with the tentative title Khalij-e Fars (lit. 'Persian Gulf', a name reserved for the lead ship of Project Loghman) before her name being changed to the current. Though not officially acknowledged, TankerTrackers, a firm that tracks maritime traffic, has identified her as a Japanese-built ship completed in 2010, previously named Beta and earlier Al Buhaira, and whose AIS signal was last detected in 2019 near United Arab Emirates. Her intended task/purpose is to support naval units in remote waters, especially in the North Indian Ocean, the Bab-el-Mandeb and the Red Sea.
