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.
Arab states of the Persian Gulf
The Arab states of the Persian Gulf are the seven Arab states which border the Persian Gulf, namely Bahrain, Iraq, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates (UAE). This excludes the non-Arab state of Iran. All of these nations except Iraq are part of the Gulf Cooperation Council (GCC), and prefer to use the term "Arabian Gulf" rather than "Persian Gulf".
