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.

On 4 June 2006, Khamenei said that Iran would disrupt energy shipments from the Persian Gulf region (about 20% of the world's daily supply of oil passes from the Persian Gulf through the Strait of Hormuz very close to Iran's coast) should the country come under attack from the US, insisting that Tehran will not give up its right to produce nuclear fuel.
