Islamic Republic of Iran Navy
It is charged with the responsibility of forming Iran's first line of defense in the Gulf of Oman and beyond with the mission of acting as an effective blue-water navy. However, it is generally considered as a conventional green-water navy as it mostly operates at a regional level, in the Persian Gulf and Gulf of Oman but also as far afield as the Red Sea, the Mediterranean Sea and northwest quarter of the Indian Ocean. In July 2016, the Navy said that it would establish a presence in the Atlantic Ocean, of unspecified duration.
History of the Islamic Republic of Iran
Shortly after the success of the revolution, revolutionary leader Ruhollah Khomeini began calling for Islamic revolutions across the Muslim world, including Iran's Arab neighbor Iraq,
the one large state besides Iran in the Gulf with a Shia Muslim majority population. The leadership in Tehran believed that they would launch a massive Shiite uprising across the Middle East and after Iraq's defeat, march on Israel and destroy it.
