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.

In 1977, the bulk of the fleet was shifted from Khorramshahr to the new headquarters at Bandar-e Abbas. Bushehr was the other main base; smaller facilities were located at Khorramshahr, Khark Island, and Bandar-e Imam Khomeini (formerly known as Bandar-e Shahpur). Bandar-e Anzali (formerly known as Bandar-e Pahlavi) was the major training base and home of the small Caspian Sea fleet, which consisted of a few patrol boats and a minesweeper. The naval base at Bandar Beheshti (formerly known as Chah Bahar) on the Gulf of Oman had been under construction since the late 1970s and in late 1987 still was not completed. Smaller facilities were located near the Strait of Hormuz. Iran also announced that new base is established in the Oman Sea.
