Operation Morvarid (Persian:عملیات مروارید "Operation Pearl") was an operation launched by the Iranian Navy and Iranian Air Force against the Iraqi Navy and Air Force on 28 November 1980 in response to Iraq positioning radar and monitoring equipment on the Al-Bakr and Khor-al-Amaya oil rigs to counter Iranian air operations. The operation resulted in a victory for Iran, which managed to destroy both oil rigs as well as much of the Iraqi Navy and inflicted significant damage to Iraqi ports and airfields. It should not be confused with the Operation Morvarid launched by the NLA in the 1990s.
