القوات الجوية الإيرانية
Following the Iranian Revolution in 1979, the Orions continued in service, after the IIAF was renamed the Islamic Republic of Iran Air Force (IRIAF). They were used in the Tanker War phase of the Iran–Iraq War and were operated by one of the most successful squadrons of the IRIAF during that conflict. A total of four P-3Fs remain in service.
