Construction and career
The ship was laid down in 1977 at Uljanik Shipyard, SFR Yugoslavia and she was launched in 1978. Ibn Khaldun was commissioned on 20 March 1980.

She was mainly used for training and as transport between Europe and Gulf of Aqaba during Iran–Iraq War. The ship was still operational in 1988, despite several Iranian claims that she had been sunk.

Ibn Khaldun was severely damaged by air attacks while at Basra in February 1991 as the result of Operation Desert Storm. The ship was later renamed to Ibn Marjid. Ibn Marjid survived the Gulf War, but her overall condition was deteriorating and she lacked spare parts for her Roll-Royce engines. She was able to sailed briefly in March 2003 during the U.S. invasion of Iraq, but later was sunk at harbor by air attacks.
